Instructions
Step 1
Preheat oven to 350°F. Line four 7” with parchment rounds, and grease with non-stick cooking spray.
Step 2
Mix together all dry (flour, baking powder, sugar, and salt) in a stand mixer with a paddle until fully combined.
Step 3
Mix chunks of room-temperature butter slowly into the dry mix, on a low speed. Continue to mix until no large chunks of butter remain, and the mixture becomes crumbly.
Step 4
Pour in egg whites, and mix on low until just incorporated. Mix in the buttermilk in two installments, on a low speed. Add in vanilla and oil, and mix at a low speed until fully incorporated. Slowly mix in the melted white chocolate. Scrape down the sides of the bowl with a spatula, then beat on medium speed for about 30 seconds.
Step 5
Weight out half of the batter, in a separate bowl. Use pink gel food coloring to color the batter a vibrant shade of pink.
Step 6
Divide evenly between the prepared cake pans, to make 2 white layers, and 2 pink layers. Bake for about 37 minutes (or until a skewer comes out clean). Allow to cool for 10 minutes, then run an offset spatula around perimeter of the pan to separate the cake from the pan. Place cake layers into the freezer for 45 minutes, to accelerate the cooling process.
Step 7
Once the layers have fully cooled, I like to trim the caramelized bits from the sides of the layers using a serrated knife. While these layers bake pretty flat, sometimes I’ll also trim the top of the layers too. Be sure the layers are completely cooled or chilled before trimming. If you try to trim the layers while they’re still warm, they will crumble apart.
Step 8
While the layers bake, prepare the white chocolate frosting. Beat the butter on a medium speed for 30 seconds with a paddle attachment, until smooth. Slowly add in the powdered sugar, 1 cup at a time. Alternate with small splashes of cream. Once fully mixed, add in the vanilla, salt, and melted white chocolate. Beat on low until the are fully incorporated, and the desired consistency is reached. If the frosting is too thick, add in cream (1 teaspoon at a time). If the frosting is too thin, add in more powdered sugar (quarter of a cup at a time).
Step 9
NOTE When making frosting for a cake, it is important to mix the buttercream on low at the end of the process for a couple minutes, to get out any extra air that might have be incorporated during the mixing process. This will make it easier to get super smooth sides on your cake!
Step 10
Next, make the pink, white chocolate ganache! Heat heavy cream in a heat-proof bowl in the microwave for 45 seconds-1 minute, until bubbling. Gently pour white chocolate chips into the heavy cream, making sure they are fully covered with cream. Allow mixture to sit for 2 minutes. Stir slowly until the cream and white chocolate are combined, then heat again for 20 seconds and stir. Repeat as necessary until all the chocolate bits are fully melted and incorporated. Then add gel food coloring, and mix until evenly colored. Allow to cool until desired viscosity is reached.
Step 11
If it seems too thin or thick, you can add a touch more chocolate chips or heavy cream! The type of cream and white chocolate that you use can affect the consistency, so feel free to adjust as needed. I like to put my ganache into plastic squirt bottles when decorating cakes, but you can also use a spoon to drizzle it over cakes.
Step 12
Stack and frost layers on a cardboard cake round. Frost an even layer of white chocolate buttercream on top of each cake layer, and add a generous drizzle of white chocolate ganache. Sprinkle with non-pareil sprinkles. Repeat with remaining cake layers, alternating the pink and white layers.
Step 13
Cover the cake in a thin crumb coat, and chill in the freezer or fridge for about 5 minutes. Once the crumb coat is firm to the touch, add a second layer of frosting. Smooth using a bench scraper. You can see a full tutorial on how to frost a cake with smooth sides here.
Step 14
To add the pink ganache drips, chill the cake for 10 minutes in the freezer (the cake needs to be cold for the drips to stay in place). Always be sure to do a test drip, to ensure that your ganache is at the right temperature. Place the cake back in the freezer for another 10 minutes, to ensure the drips chill to keep them in place.
Step 15
Then add frosting swirls around the top of the cake using a wilton 4B tip. Place a circus animal cookie on top of each swirl, and add non-pareil sprinkles around the top, and base of the cake.
