Ingredients
- 1 box chocolate cake mix (use your favorite or a low-sugar version for a healthier alternative)
- 1 cup peanut butter cups, chopped (about 6-8 regular-sized peanut butter cups)
- 1 cup unsweetened applesauce (as a substitute for oil to make the cake lighter)
- 1 cup milk
- ½ cup chocolate chips
- ¼ cup peanut butter
- 1 tsp vanilla extract
- 1 cup water
Instructions
Preheat the Oven
Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish to ensure the cake doesn’t stick.
Layer the Ingredients
Start by pouring the cake mix directly into the baking dish. Don’t worry about mixing it with anything else. Layer the chopped peanut butter cups over the cake mix evenly. Next, scatter chocolate chips and drizzle peanut butter over the top for that rich, creamy texture.
Add the Wet Ingredients
In a separate bowl, whisk together the applesauce, milk, vanilla extract, and water. Pour this mixture evenly over the dry ingredients in the baking dish. The cake mix will begin to absorb the wet ingredients, and the layers will start to form.
Bake the Cake
Place the dish in the preheated oven and bake for 35-40 minutes or until the top is golden brown and a toothpick inserted in the center comes out clean. The cake will bake into a crisp top with a gooey, peanut butter-chocolate filling underneath.
Serve & Enjoy
Allow the cake to cool for about 10 minutes before serving. Scoop it out into individual servings, and top with a scoop of vanilla ice cream or a dollop of whipped cream for the ultimate indulgence.
