Bakery Style Whoopie Pie Cake

Submitted by wannabecook

"I found this recipe on a website for parents. The original was for the actual Whoopie pies, but I am too lazy for all of that. I altered a little and made a cake out of it. It is awesome and so worth the work. Note: use real butter, makes it much better."

• For Cake

• 1 (18 ounce) box devil's food cake mix
• 3 eggs
• 1⁄2 cup buttermilk

directions

1. For the cakes: Heat oven to 350°F; line 2 cake pans with parchment paper.

3. Pour half of batter into each cake pan. Cook approximately 20 minutes, or until cakes spring back when pressed. Cool completely on baking sheets, at least 1 hour.

4. For the filling:

5. With electric mixer on medium speed, beat butter and sugar together until fluffy, about 2 minutes. Beat in vanilla and salt. Beat in Fluff until incorporated, about 2 minutes. Refrigerate filling until slightly firm, about 30 minutes. (Bowl can be wrapped and refrigerated for up to 2 days).

7. This is also good if you heat a can of frosting for 20 seconds and pour over the cake.

These were yummy and went fast at school. I cut back on 1/2 cup water so that I could make little whoopie pies. I added chocolate vodka to the cream filling instead of the extract. I added a teaspoon or so of expresso power to the cake batter too. These were for grow-ups and they loved them!
