Ingredients 2 tablespoons butter 2 tablespoons peanut butter 1/2 teaspoon vanilla 1 egg 2 tablespoons sugar 2 tablespoons flour 3 tablespoons cocoa powder 1/8 teaspoon salt 1/8 teaspoon baking powder 3 tablespoons chocolate chips Melt the butter in a small dish. Add the peanut butter and mix well. In the mug, mix together the vanilla, egg, and sugar until well combined. Combine the flour, cocoa, salt, and baking powder and add to the mug. Pour in the peanut butter/butter mixture and mix well. Stir in the chocolate chips. Put in the microwave for 1-2 minutes or until desired doneness is reached (all microwaves are different so you might have to experiment a little. I only do it for about 1 minute). Top with peanut butter pie mousse and hot fudge. Peanut Butter Pie Mousse 1 tablespoon softened cream cheese 1 tablespoon peanut butter 1/2 teaspoon vanilla 2 tablespoons whipped cream or cool whip 1 tablespoon powdered sugar Mix together the cream cheese, peanut butter, and vanilla. Fold in the whipped cream. Sift in the powdered sugar (I just used a fork) and fold that in too, trying not to over stir.
