How to Make Whoopie Pie Cake
- Preheat oven to 350°F (175°C). Grease and dust two 9-inch round cake pans with cocoa powder.
- In a large bowl, cream together the softened butter and granulated sugar until light and fluffy.
- Beat in the eggs one at a time until well combined.
- In a separate bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt.
- Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk, beginning and ending with the dry ingredients. Beat for 2 minutes.
- Divide the batter evenly between the prepared cake pans.
- Bake for 25-30 minutes, or until a wooden skewer inserted into the center comes out clean.
- Let the cakes cool in the pans for 10 minutes before inverting them onto a wire rack to cool completely.
- While the cakes are cooling, prepare the frosting: In a medium saucepan, whisk together the milk and flour until smooth.
- Cook over medium heat, stirring constantly, until the mixture thickens and comes to a gentle boil. Reduce heat and simmer for 1 minute, stirring constantly.
- Remove from heat and let cool completely.
- In a separate bowl, cream together the softened butter and powdered sugar until light and fluffy.
- Beat in the vanilla extract.
- Gradually add the cooled flour mixture to the butter mixture, beating on high speed until light and fluffy and resembles whipped cream.
- Once the cakes are completely cool, place one layer on a serving plate and frost the top generously.
- Top with the second cake layer and frost the top and sides of the cake.
- Dust with cocoa powder, if desired.
