Peanut Butter Cake:
3 1/3 cup all-purpose flour
1 tablespoon baking powder
1 1/2 teaspoon baking soda
3/4 teaspoon salt
1 cup Justin's Classic Peanut Butter
1/2 cup unsalted butter, softened
3/4 cup sugar
3/4 cup light brown sugar
1 2/3 cup buttermilk
3 sticks unsalted butter, softened
1 cup unsweetened cocoa
5 cups confectioner’s sugar
½ cup milk
2 teaspoons vanilla
Preheat oven to 350 F. Grease and flour three 9-inch round cake pans. Set aside.
In a medium bowl, whisk together the flour, baking powder, baking soda and salt.
Using an electric mixer, beat the peanut butter, butter and sugars together on medium speed until light and fluffy.
Add the eggs one at a time, beating for 1 minute between additions and scraping down the sides of the bowl before adding the next.
Reduce the mixer speed to low and alternate adding 1/2 cup of the flour mixture and 1/3 cup of the buttermilk, until just combined.
Divide the batter between the prepared pans and bake until a toothpick inserted into the center comes out clean, 15 to 22 minutes. Cool in pans for 10 minutes, then cool completely on a wire rack before frosting.
