Vanilla Butter Cake with Marzipan Buttercream

This is the layer cake version of the mega moist/buttery vanilla cupcakes that I posted this summer! I’ve altered the ratios just slightly from the cupcakes here in order to provide the stability in the batter necessary to hold up a full layer, and it took a zillion test runs, but I’m proud to say that it retains the lusciousness that I was so pleased with in those cupcakes. It’s perfectly vanilla-y and just sooo… whatever the opposite is of those wildly airy grocery store sheet cakes. (Not (!) that there isn’t a time and place for those.) But Eggpop and I share a particular love of two important things: rom coms and very dense cake.

And such a hard earned cake is worthy of an equally lush frosting, no?

Marzipan buttercream is not an idea that I can take credit for, even though I’d like to since, as we’ve already established, my body is made up of 1/2 marzipan around the holidays. Alaina, who I met at my very first Molly on the Range book tour event, made the cutest ever cake earlier this year and added the marzipan butter from MOTR (which is essentially your basic ingredients for marzipan, blanched almonds and sugar, blended into oblivion until silky and spreadable) to the frosting. Brilliant!!!!!! Right??? I immediately knew I had to try it with my favorite go-to buttercream and the results were as I expected: otherworldly. Almondy, buttery, sweet, the best. You know I love a good rustic nut butter frosting, but using a blanched nut butter here makes this frosting so smooth and dreamy. I mean, marzipan on its own is obviously the best thing ever, but how do you make the best thing ever even better? Add butter. Duhhh.

And obviously if you are going to bestow the name “marzipan” onto any type of frosting, you are going to use great butter for it. Land O Lakes® European Style Unsalted Butter is what I’m using here and its flavor is so good and pure that if there’s any butter who deserves to be mashed up with marzipan, it is this. And then, rather than making the full marzipan butter recipe (which you can find in Alaina’s post and which also makes a great little gift when put in a cute jar) before adding it to my buttercream, I’ve rearranged the ingredients a bit to make things a little more straightforward and to take it easy on your food processor since it’s already getting quite a workout making the blanched almond butter. 

The decorations here are inspired by embroidery again, just like these cookies! I referenced these awesome trees and then here is a video that goes more in depth with the decorating process:

1 tsp almond extract, optional

3 tb (45g) heavy cream

clues

To make the cake layers: preheat the oven to 350ºf. Grease and line the bottoms of three 8” cake pans with parchment and set aside.

In a large bowl, sift together the flour and baking powder, and then lightly stir in the salt and set aside. in a large measuring cup, whisk together the heavy cream and sour cream and set aside. 

In a stand mixer fitted with a paddle attachment, cream together the butter, coconut oil, and sugar on medium high for 3-4 minutes, until light and fluffy. Add the eggs, one at a time, beating well after each. Add the vanilla and almond extract, if using. Reduce the mixer to medium low and add the dry mixture and cream mixture in 3 alternating additions, mixing until just combined. Distribute the batter evenly between the cake pans and spread it out evenly.

Bake until the  tops of the cakes are thinking about starting to turn brown and a toothpick inserted into the center comes out with a few crumbs on it; begin checking for doneness at 30 minutes and try your darnedest not to let it overbake. Let cool in the pans for 10 minutes and then transfer to a wire rack to cool completely. 

To make the buttercream: 

First, make the almond butter. In a high powered food processor, blend the almonds, scraping the sides occasionally, until very creamy and spreadable, about 5-10 minutes.

In a stand mixer fitted with a paddle attachment, beat together the butter and almond butter until creamy. Gradually add the powdered sugar, and then mix in the salt, vanilla, almond extract, and heavy cream. Mix until creamy.

To frost the cake, level the top of the layers and then stack them up with a layer of frosting in between. Frost all over and decorate as desired (See video!)! Enjoy!


-yeh!

Thank you so much to Land O’Lakes for providing me with the butter and heavy cream for all of my cake baking adventures and for sponsoring this post. Their European style butter is so gosh darn rich and perfect for buttercream.
