Peanut butter and chocolate is a favorite combination the world over, and is featured at The Cake Bake Shop with Gwendolyn's Peanut Butter Mousse Pie. Crushed chocolate wafer cookies and melted Callebaut Belgian chocolate are mixed together, creating a deep chocolatey pie crust. Filled with a mixture of heavy cream, peanut butter, and a touch of cream cheese. It tastes like a Peanut Butter Cheesecake, melted Callebaut Belgian chocolate ganache is poured over the top with roasted chopped peanuts. Delicious!.
