Peanut Butter Chocolate Cake – my 30th birthday cake!

Me and my cake!

Birthdays are pretty special regardless but I think some are more special than others. 16 is a big deal as it brings about the freedom of a drivers licence, in BC (and most of Canada) 19 is important since it signifies what I am going to call “the new responsibilities that go along with being legal drinking age”, and then it is 30. There is no real reason that 30 should be special as nothing actually changes in life at that age but it seems that 30 is the end of the “younger years”. To me it has always been the age where you really start to ‘get’ life. You know who you are. You know what you want (and of course don’t want). You know what is important to you. You have the ability to say no to the things that aren’t. And you just really are ready for real life to “bring it!” That was me this past weekend. And just to be clear: I actually had been looking forward to my 30s for years! It even happened that my 30th birthday was on a Saturday!

So it may have rained... but it was still fun!

The day started early – by my choice. I wanted to run a race. Now I have run enough races that it wasn’t like I wanted to do something new and exciting on my 30th, I just wanted to start the year with something I loved and something that I find important in my life! So a 10km race in the rain! It was a blast. I had 3 friends join for the run and one that came as “support crew”. The beginning was a lot of fun as 3 of us chased each other and traded on the lead. And then it settled in to me following closely behind one friend for the rest of the race while the other two followed not far behind. I was hoping that I would have this burst of speed at the end and pass my friend but apparently he also had some kick for the end so I followed in behind 13 seconds after him at a decent race time of 53min35sec. A good start to the day!

The Chocolate Batter... it is SO delicious!

Anyways, this is a baking blog so I better cut to the chase! Of course I needed to make a cake. I understand that some may think it is taboo to make your own cake but I really wanted to make it! For me it was a special treat! I love making desserts for other people and I love to make perfect desserts for the tastes of the recipient (so mango cake for my mango loving friend, chocolate coconut cupcakes for my friend that has loves that flavour combo,  lemon for the lemon lovers, etc). So for me, it was extra special to make the cake that I would want! Instead of it being a hassle or extra work for me when I should be “enjoying”, it turned into being allowed to make MY perfect cake! What a treat!

The Peanut Butter Batter... also delicious!

My favourite flavour combination of all time isn’t very refined or very mature: it is the classic chocolate and peanut butter. I love it. It is simply the perfect balance! Of course this is what my cake had to be. I had made chocolate cupcakes (I’ll post those later this week) the previous weekend so I made the middle layer of the cake from that and froze it (I’ll add the link for that part of the cake once I write it). The other two layers – top and bottom – had to be peanut butter cake. And between the layers, well that was a mixture of several things. First, on the bottom was chocolate ganache (leftover from the cupcakes as well) and a peanut butter buttercream. Then, between the 2nd & 3rd layers was leftover chocolate marshmallow mousse (or that is what I am calling it). (Apparently I needed to use up some leftovers!) The cake was then covered in more peanut butter buttercream. And then came the home made chocolate fondant. I thought this was a good time to try making my own! That will be a post all on its own! (If you choose to make this recipe, it is not necessary to use the same fillings as I did! But if you want my opinion, I would go with the Chocolate Marshmallow Mousse filling.)

It turned out AMAZING! Although I don’t love the taste of fondant, I love how it seals in the moisture and makes for a more delicious cake! This fondant was also tastier and less gummy than most. We went for dinner at a fantastic restaurant that had prepared a 3 course meal especially for us (with a menu that had my name on it!) including dessert but everyone was still ok with eating a 2nd dessert and most finished it!! Those that didn’t (including myself) took home their leftovers! Although it was quite rich, I only heard rave reviews (unless they were just being nice to me because it was my birthday!)

Fondant'ed cake sans decorations

Now for the shape, I couldn’t just do a regular round or square cake – I wanted a giant Whoopie Pie cake! (Just in case someone missed it – I love making Whoopie Pies and you should check out my Whoopie Pie blog!) So I carved a little here and there, cut the top to a dome shape, carved the chocolate cake to be about an inch smaller in diameter and then shaped the fondant over the top. I also piped more peanut butter buttercream around the outside as the “filling” for the Whoopie Pie! It turned out almost identical to my vision in my head (except for the imperfections in the fondant).

On the top, well I couldn’t write “Happy Birthday Becky!” That seemed a little odd. So I went with a quote from a movie. Although I am not “13 Going on 30”, like I said before, I had been looking forward to 30 as I saw myself being “Flirty, 30 and Thriving”… uh oh, as I write this now I just realized it is supposed to be “30, Flirty and Thriving”. I don’t know why I got ‘flirty’ in my head first. Oh well, too late! The cake was made and eaten as a tribute “to being flirty, 30 and thriving!”

The Finished Cake!! It was SO delicious!

Decadent Buttermilk Chocolate Cake

Ok, so I am not putting the recipe here (this post is crazy long as is!), I am putting it on another post linked here. The recipe made enough for 1-9″ layer, 12 regular sized cupcakes and 12 mini cupcakes. If you want to just use it for this cake, you should likely only make 1/2 the recipe and make an additional 6-8 cupcakes (or make 2 layers and freeze one for use later).

Peanut Butter-cup Cake
(from Best-Loved Desserts by Good Housekeeping – an awesome cookbook!)

  • Mixing up the Peanut Butter-cup Cake

    2 cups flour

  • 1 tsp baking powder
  • 3/4 cup creamy peanut butter
  • 1/2 cup soft butter
  • 1 cup white sugar
  • 1/2 cup packed brown sugar
  • 2 eggs
  • 2 tsp vaninlla
  • 2/3 cup milk
  1. Preheat oven to 325°F. Grease 2 9″ cake pans and line the bottoms with parchment paper.
  2. In a small bowl, whisk together flour and baking soda.
  3. With a stand mixer, beat butter and peanut butter a minute or so until creamy. Add both sugars and continue beating for a few more minutes. Add eggs one at a time and then the vanilla.
  4. Alternate between adding the flour and the milk, begin & end with the flour. Beat just until smooth.
  5. Split batter between the two pans and bake about 40-45 minutes.
  6. Cool cake in pan 15-20 min before removing it to cool completely on a rack.

Chocolate Ganache

Scald 1/2 cup of whipping cream but don’t let it boil (it should just start to have bubbles on the top.) Pour over 1/2 cup or 4 oz chopped semi-sweet chocolate. Let sit 2 min then stir until smooth. Allow to cool before using.

Peanut Butter Buttercream

Oops, I should have payed more attention to what I did! I just made this up as I went and didn’t measure a single thing. Basically what it was was 1/2-3/4 cup peanut butter, 1/4 cup cream cheese, 1/4 cup butter, 1 tsp vanilla and about 3-4 cups of icing sugar. Add cream/milk 1 tsp at a time until the icing is a good consistency for icing. Sorry I can’t say for sure what it was! (I actually used some leftover cream cheese icing and added peanut butter and more sugar to it so this is why I really don’t know!)

Chocolate Marshmallow Mousse Filling

See the filling here for the Whoopie Pies I previously made.

Chocolate Fondant

This recipe and process will get its own entire page! But you will have to wait a couple days!


Mmm... that was one good piece of cake!! YUM!!!

Of course you can use whatever filling you want but this is what I did!

  1. Start with a layer of the Peanut Butter Cake.
  2. Spread ganache over the top and then peanut butter buttercream over the cake layer.
  3. Cover with the chocolate cake layer.
  4. Spread the Chocolate Marshmallow Mousse on top of the chocolate cake.
  5. Top with the Peanut Butter Cake.
  6. Cover the whole thing with Peanut Butter Buttercream.
  7. Cover with rolled chocolate Fondant!


My First Fondant Cake! Lemon Blueberry Delight!

Lemon Blueberry Layer Cake with Lemon Curd and Lemon Swiss Meringue Buttercream

The time had come: it was time to try fondant! I have been watching all the fabulous cake shows on the Food Network and TLC for years but I had never tried it myself. Once, I bought a small package with intentions to try it but never did get around to it! I am not sure if it was out of fear of the unknown or just laziness? I think partly I just didn’t quite know what to do with it! So finally after these many years of baking, I learned how to at the cake decorating class. I went a little wild with the colours and would maybe tone it down next time but it was fun! Generally I find that I need more colour than I would expect to get the colour I want so cake covering I added quite a bit only to find that the pale green that I was hoping for was instead an intense shade that made the cake look like a play-do creation! Oh well! I made the flowers all ahead of time (and I wanted them to be intensely coloured) so it was just a matter of putting it all together.

The completed cake

I have to confess, by the time I was done, I wasn’t sold on fondant cakes. I do like how perfectly smooth the cake can look and some of the fun things you can do with it, but I sort of like the more rustic look of piping icing. And there is something fun about piping that you just don’t get from using cutters for flowers. Maybe this also stems from the fact that I don’t really like making cut cookies – the rolling, the cutting, the re-rolling, more cutting, the sticking, the flour everywhere… and on and on. It gets kind of irritating by the end so fondant flowers seem to feel about the same (except you feel like you have shortening everywhere instead of flour!)

One delicious slice! Because the cake was so moist and there was so much amazing curd, the cake started to collapse a bit almost as soon as it was cut.

For the cake itself, I went with a recipe from one of my new favourite blogs. I say “new favourites” when in reality I have just recently actually started following people’s blogs more. I had used recipes from blogs before but I have never actually subscribed to any or frequently checked any one in particular. Anyways, my new favourite one for phenomenal cakes is Sweetapolita. She makes these amazing looking cakes with beautiful layers and takes gorgeous pictures of each of them. Although I am pretty sure my cakes taste as fantastic as hers, I need to learn a lot from her about taking pictures! Mostly I have figured out that I need some white kitchenware! And I need to pay attention to the backgrounds that I use to take the pictures. Although I took the pictures of the process at home (at night… with a light bulb burnt out), the final product was only photographed at work so there wasn’t too many options for backdrops!

Now onto the baking. As I said, the cake recipe is from Sweetapolita (slightly modified) and can be found here. It varies ever so slightly from a recipe found on Epicurious. I filled the cake with lemon curd. For the icing, I went with a Lemon Swiss Meringue Buttercream rather than my usual buttercream as often people find buttercream too sweet. I am going to say now that this was a delicious cake! Super moist and the lemon curd was amazing (although I already knew it would be!)

A little extra lemon!

No low fat here!

So to start: the ingredients. Normally I wouldn’t have whole milk but I bought some for baking purposes. Plus the full-fat sour cream and an organic lemon. I used to buy low fat only but have decided that if you are baking, what difference does it make if you buy low fat or high fat? It is DESSERT! May as well make it to its best!

For the Lemon Curd and the Lemon Swiss Meringue Buttercream, I went to Martha… the recipes are adapted from her cupcake cookbook.

Here is how I did it – although you could definitely do it differently. I decided to make three 9″ layers and put blueberries in 2 of them while leaving the third just lemon. You could do 8″ pans and you could do just 2 layers as mine were pretty thin. With the cooled cakes, I then wrapped them tightly in Saran Wrap and put them in the freezer for awhile. I think this is supposed to make them so they aren’t as crumbly when you ice them. I left them too long though and so they were so cold that when I went to ice them, the buttercream went harder than I would have liked. Anyways, start with the bottom layer, then pipe a layer of buttercream around the outside to create a dam to hold the lemon curd in. Scoop in half the lemon curd. Top with your next layer and repeat the dam/lemon curd treatment. Top it off with your final layer and then ice the entire cake. From there you can decorate it however you wish! Like I said, I went with the fondant!

Lemon-Blueberry Layer Cake

Mmm... the delicious batter is ready!

  • 2 cups plus 6 tablespoons all-purpose flour
  • 2 teaspoons baking powder
  • 3/4 teaspoon salt
  • 2 cups fresh blueberries
  • 1/2 cup sour cream
  • 1/2 cup whole milk
  • 2 teaspoons vanilla extract
  • 3/4 teaspoon pure lemon extract
  • ~1tsp lemon zest from one lemon
  • 1 cup (2 sticks) unsalted butter, softened
  • 1 1/2 cups white sugar
  • 4 large eggs
  1. Preheat oven to 350°F. Butter (and use parchment paper if your pans stick frequently) three 9″ round cake pans.
  2. Whisk together the dry ingredients (flour, baking powder and salt) in a medium bowl.

    The blueberries & flour

  3. In another bowl, put your washed blueberries and then add 1 tablespoon of the flour mixture and stir to coat them. This keeps them from sinking to the bottom of the pan I think!
  4.  Stir together milk, sour cream, extracts and lemon zest. It doesn’t matter if it is perfectly mixed though.
  5. In a stand mixer (or with hand beaters), beat butter briefly and then add sugar. Beat a few minutes until pale yellow and fluffy. Add eggs one at a time until well combined.
  6. Mix in flour mixture alternating with milk mixture. Add the flour in 3 batches and the milk in 2 (so add flour, then milk, then flour, then milk, then end with flour). Mix until just combined.
  7. Gently fold in blueberries (I divided my batter into 3 and added the blueberries to only 2/3 as mentioned above but you can do it as you wish).
  8. Divide the batter between the prepared pans. Bake 20-25 minutes until a toothpick poked into the centre comes out clean.
  9. Cool cakes in pans on racks for 10-20 minutes and then remove from pans to cool completely.

The layers ready for baking!

The baked layers - cooling beside my cat oven mitt! I am not a crazy cat lady, I just like to pretend!

Lemon Curd

  • 2 whole eggs plus 8 egg yolks
  • 1 cup sugar
  • 2/3 cup fresh lemon juice (or mix of fresh and bottled)
  • 2 Tb unsalted butter, room temp, cut into small pieces
  1. Combine eggs, yolks, sugar & lemon juice in a bowl of a double boiler. Set over simmering water.
  2. Cook whisking constantly until the mixture is thick enough to coat the back of a spoon.
  3. Remove from heat and add the butter a few pieces at a time. Stir well between each addition.
  4. Cover with plastic wrap – pressing it directly against the surface to prevent a film from forming – and refrigerate several hours.

Lemon Swiss Meringue Buttercream
Note: Sweetapolita has some great tips for Swiss Meringue Buttercream 

  • 1 cup + 2 Tb sugar
  • 5 large egg whites
  • 1 3/4 cups unsalted butter, cut into tablespoons, room temperature
  • 1 teaspoon pure vanilla extract
  • 1/2 tsp lemon extract
  • 1/2 cup lemon curd
  1. In the top of a double boiler over simmering water, heat the sugar and egg whites. Whisk while heating until 140°F. Remove from heat and transfer to the bowl of a stand mixer with the whisk attachment.
  2. Whip the meringue by beating on low to start, until foamy, and then increasing the speed. Beat until stiff, glossy peaks form and the mixture is cooled completely (test by touching the outside of the metal bowl). This takes about 10 minutes.
  3. Mix in the butter a few tablespoons at a time. Beat between each addition until the butter is fully incorporated.
  4. Don’t worry if it looks kind of curdled during the process, keep beating as it will come together at the end.
  5. Beat in the extracts and lemon curd.
  6. To finish, switch to the paddle attachment and beat a few extra minutes to reduce air bubbles.
This can be stored in the fridge until you are ready to use it. Just bring it to room temp again and give it a few beats to fluff it up nicely.
