harder than it looks
Ahh..hubris.
The San Francisco MOMA sells a beautiful Mondrian cake for $8 a slice. It’s a museum attraction unto itself:
With my masterful understanding of economic theory, I decided to make my own Mondrian cake, which I could then sell for $7 a slice. Devious! Unfortunately, it is a lot easier to boast about making a Mondrian cake than actually making an intriciate, perfectly square art cake that is worth charging $7 a slice for.
My recipe was a basic white velvet cake and dark chocolate ganache, both adapted from (say it with me now) Rose’s Heavenly Cakes. In retrospect, a denser pound cake would have worked a lot better structurally. My blue and yellow food coloring was hastily purchased from the grocery store and the color concentration was so miserable that after using the entire tube on a quarter-batch of batter, I had only the palest of icy blues. I was able to achieve pureed a decent blue color by pureeing frozen blueberries and mixing it in with the batter and scrapped the yellow cake completely.
The ganache on the bottom of the cake stuck to the wax paper, forcing me to serve the cake on the same messy sheet that I had decorated it on, losing me presentation points right off the bat. Cutting so many small squares left crumbs all over the table, and it was very difficult to get a crumb-free frosting. Any unevenness in pressure in applying the frosting led to deformation of the cake, and the square shape gradually deteriorated into an irregular trapezoid.
The only good thing about a project like this is the sheer quantity of leftover cake you get to eat. There is excess red and blue cake, excess white cake, and two endcaps that need to be sliced off to even out all the strips of cake. Delicious, if a bit sad to look at.
Total creation time was about 3 hours, which included baking three cakes in two batches.
White Velvet Cake from Rose’s Heavenly Cakes
3 large egg whites (90 g)
2/3 cup milk (160 g)
1.5 teaspoon vanilllla extract
2 cups cake or AP flour (200 g)
1 cup baker’s sugar (200 g)
1/2 teaspoon salt
1 stick unsalted butter, softened (113 g)
The recipe above makes one 9×2 round cake, I scaled it up to a 9×2 square cake which entails multiplying everything by 1.27.
Whisk the egg whites, vanilla, and a few tablespoons of milk together until combined.
In a large bowl, beat together the flour, sugar, baking powder, and salt until well combined and any clumps are broken up. Add the butter and remaining milk and slowly increase the speed to medium and beat for 1½ minutes, scraping the sides of the bowl as necessary. The batter should be light and fluffy.
Add half of the egg mixture and beat for 30 seconds, then the other half and beat for another 30 seconds. Scrape the batter into the prepared pan and bake until a cake tester comes out clean and the cake springs back when pressed lightly in the center, about 30-40 minutes.
One batch of batter can be divided into two standard 9″ loaf pans to make the blue and red cakes. Mix in either food coloring or a fruit puree until desired color is reached and bake.
Cool completely before frosting.
Dark Chocolate Ganache
12 oz dark chocolate (62%)
5 oz heavy cream, warm
2.5 oz unsalted butter, softened
1 teaspoon vanilla extract
Melt the chocolate in a double boiler, remove from heat and add in the heavy cream, stirring until even in color and texture. Allow the chocolate to cool until warm to the touch and and gently stir in the butter and vanilla. Ganache will thicken when allowed to cool. To apply in thin layers, I ended up drizzling warm ganache to get an even application and then smoothing it out and scraping off the excess with a spatula after it thickens upon cooling. This helps to avoid stirring up any crumbs from the soft cake.
