This may be the most delicious cake I've ever made... if you love chocolate, that is!
Chocolate cake layers with oreo French buttercream, a chocolate ganache glaze, and more oreos on top! My sister requested this cake for her father-in-law for father's day.
Oreo French Buttercream
8 egg yolks
1 cup sugar
1 tsp vanilla extract
4 sticks unsalted butter, softened
12 whole oreo cookies (with the creme intact), processed into crumbs in a food processor
Place the egg yolks, sugar, salt, and vanilla in the bowl of your stand mixer and set it over a saucepan with an inch of simmering water. Whisk until the temperature reaches 150F. All the sugar should be dissolved. Place the mixer on its stand and whip on high speed for 7 minutes until cooled to room temperature. Mixture will be much paler in color and very light and fluffy. On medium speed, add the butter 1/2 stick at a time. Increase speed to medium high and whip until smooth. Add the oreo crumbs and mix just until combined.
