Ingredients
For the Cake Layers:
- 1 box (15.25 oz) sugar-free chocolate cake mix
- 1 cup unsweetened applesauce
- 3 large egg whites
- 1 cup water
For the Peanut Butter Layer:
- 1 package (8 oz) light cream cheese, softened
- 1/2 cup powdered peanut butter (like PB2), mixed with 1/4 cup water
- 1/4 cup powdered sugar or zero-calorie sweetener equivalent
- 1 tub (8 oz) light whipped topping, thawed
For the Chocolate Topping:
- 1/2 cup semisweet chocolate chips
- 2 tbsp skim milk
- Optional: crushed peanuts or mini chocolate chips for garnish
Instructions
1. Bake the Cake Layers
Preheat oven to 350°F (175°C). Lightly spray two 8-inch round cake pans with nonstick spray.
In a large bowl, mix cake mix, applesauce, egg whites, and water until smooth.
Divide batter evenly between the pans and bake for 22–25 minutes or until a toothpick comes out clean. Let cool completely.
2. Prepare the Peanut Butter Filling
In a medium bowl, beat cream cheese until smooth. Stir in the reconstituted powdered peanut butter and powdered sugar until well combined. Fold in the whipped topping until fluffy and uniform.
3. Assemble the Cake
Place one cake layer on a serving plate. Spread half the peanut butter filling evenly over the top. Add the second cake layer and spread the remaining filling on top.
4. Add the Chocolate Topping
In a microwave-safe bowl, melt chocolate chips with milk in 20-second intervals, stirring in between, until smooth. Drizzle or spread over the top layer.
5. Chill & Serve
Refrigerate for at least 1 hour before serving to set the layers. Slice and enjoy!
