Instructions
1-First Step: Bake the Chocolate Cake LayersMix dry ingredients: 1 3/4 cups flour, 2 cups sugar, 3/4 cup cocoa, 2 tsp baking soda, 1 tsp baking powder, 1 tsp salt in a large bowl. Whisk wet: 2 eggs, 1 cup buttermilk, 1/2 cup oil, 2 tsp vanilla. Combine, then stir in 1 cup hot coffee. Batter will be thin. Divide into pans. Bake 30-35 minutes until toothpick tests clean. Cool in pans 10 minutes, then on racks fully. About 40 minutes total.
2-Second Step: Prepare the Peanut Butter Truffle FillingBeat 1 cup peanut butter and 8 oz softened cream cheese until smooth, 2 minutes. Gradually add 2 cups powdered sugar, mixing well.

This peanut butter truffle recipe sets like candy center.
3-Third Step: Assemble the CakePlace one cooled cake layer on serving plate. Spread all truffle filling evenly, 1/2-inch thick. Top with second layer. Press gently. Refrigerate 30 minutes to firm filling. Trim edges if domed for flat top.
4-Fourth Step: Make and Pour the Chocolate GanacheHeat 1 cup heavy cream until steaming, not boiling. Pour over 12 oz chopped dark chocolate in bowl. Let sit 5 minutes, then stir from center out until glossy. Cool 10 minutes to thicken slightly. Pour over cake, spreading sides with offset spatula. Refrigerate 2 hours to set ganache firm yet sliceable.
5-Final Step: Garnish and ServeSprinkle 1/2 cup crushed peanuts around edges and flaky sea salt on top. Slice into 12-16 pieces. Let sit 30 minutes at room temp before serving for best texture.
