In a microwave-safe mug sprayed with nonstick spray, combine 3 tbsp. moist-style devil’s food cake mix, 1 tbsp. egg whites or fat-free liquid egg substitute, 1 tbsp. fat-free sour cream, and 1/8 tsp. baking powder. Add 2 tbsp. water, and mix well. Microwave for 1 minute and 45 seconds, or until set. Run a knife along the edges to release the cake.Place a plate over the mug, flip, and gently shake mug to release cake onto the plate. Once cool, drizzle with 1 tsp. fat-free/low-fat/light caramel dip, and sprinkle with 1 tsp. each chopped peanuts and mini semi-sweet chocolate chips.
