Step 1

Preheat oven to 350°F. Grease a 12-14 cup bundt cake pan with butter, shortening, or spray with baking spray and dust with cocoa powder. Set aside.

Step 2

Peanut Butter Filling: In a small bowl, use an electric mixer to beat together peanut butter, cream cheese and sugar on medium speed until thick and fluffy.

Step 3

To the bowl, add the egg, beating well. Add 2 tablespoons of flour and one Tablespoon heavy whipping. Continue beating until fully combined, set aside.

Step 4

Cake: In a medium bowl, sift together the flour, baking powder, baking soda, salt, cocoa powder, and instant espresso powder using a whisk.

Step 5

In a separate large bowl, using a mixer, beat together the sugar, oil and vanilla. Add the eggs, one at a time, beating well after each addition. .

Step 6

With the mixer on low speed, add the sifted dry ingredients alternately with the buttermilk. Repeat until all has been added, then beat just until fully combined.

Step 7

Pour 1/2 of the cake batter into the prepared bundt pan. Dollop the peanut butter filling evenly over the cake batter leaving around a 1/2 inch border. (It shouldn't touch the edges). Spread the remaining batter over the filling and carefully smooth.

Step 8

Bake for about 45-55 minutes, or until a toothpick inserted into the middle of the cake comes out clean. Allow the cake to cool in the pan for 20-30 minutes on a cooling rack.

Step 9

Carefully run a knife or offset spatula around the edge to loosen if needed then carefully turn out onto a cooling rack to cool completely.
