This easy slow cooker dessert is the kind of back-to-school treat that earns an immediate spot in the weeknight rotation: minimal prep, only five ingredients, and a rich chocolate-peanut butter payoff that feels far more special than the effort involved. Using unwrapped mini peanut butter cups as the base creates pockets of creamy, candy-like flavor throughout the finished dessert, and the crock makes it especially convenient for busy afternoons when the oven is already tied up or you simply want a hands-off sweet.
Serve this warm with small bowls and spoons, or scoop it into dessert cups with a spoonful of whipped cream or a scoop of vanilla ice cream. For a lunchbox-inspired finish, drizzle on a little chocolate syrup or add a sprinkle of chopped peanuts; a glass of cold milk or hot coffee alongside balances the sweetness nicely.
Slow Cooker Peanut Butter Cup Chocolate Dump Cake
Servings: 8
Ingredients
1 box chocolate cake mix, about 15.25 ounces
Directions
1. Lightly grease the slow cooker insert. Scatter the unwrapped mini peanut butter cups evenly across the bottom.
2. In a mixing bowl, stir together the chocolate cake mix, milk, and melted butter until just combined into a thick batter.
3. Spoon the batter over the peanut butter cups and spread it gently to cover. Warm the peanut butter briefly if needed, then dollop it over the top and swirl it lightly through the batter with a knife.
4. Cover and cook on low for 2 to 2 1/2 hours, or until the edges are set and the center is soft but no longer wet. Turn off the heat and let it rest, covered, for 10 minutes before serving.
5. Spoon the warm dessert into bowls and serve as is, or top with vanilla ice cream if you like.
Variations & Tips
Make it extra chocolatey: For an even deeper chocolate flavor, use a dark chocolate cake mix if you have one on hand. The bittersweet edge helps balance the sweetness of the peanut butter cups.
Add a little texture: A small handful of chopped roasted peanuts sprinkled over each serving adds welcome crunch and reinforces the peanut butter flavor without changing the simplicity of the recipe.
Watch the cooking time: Slow cookers vary quite a bit, so begin checking at the 2-hour mark. You want a soft, pudding-like cake rather than a dry one, and the dessert will continue to set slightly as it rests.
Serve for parties: This recipe doubles nicely for potlucks or family movie nights if your slow cooker is large enough. Keep portions modest since it is very rich, and offer ice cream or whipped topping on the side for easy serving.
