Ingredients

Scale

Cake Batter

  • 1 15.25 ounce box Devil’s Food Cake mix
  • 1 3.9 ounce package instant chocolate pudding mix
  • 1 cup milk
  • 3 eggs
  • 1/2 cup butter, melted
  • 1/4 cup sour cream
  • 1 tsp vanilla extract

Mix-ins and Topping

  • 2 1.55 ounce Hershey bars, chopped
  • 4 graham crackers, broken
  • 2 cups mini marshmallows
  • Additional chocolate bars, marshmallows, and graham crackers for topping

Instructions

  1. Mix dry ingredients: In a large mixing bowl, whisk together the devil’s food cake mix and instant chocolate pudding powder ensuring an even combination.
  2. Add wet ingredients: Add the milk, eggs, melted butter, sour cream, and vanilla extract to the dry mixture. Whisk all together until the batter is smooth and free of lumps.
  3. Fold in chocolate and graham crackers: Gently fold in the chopped Hershey bars and crushed graham crackers, distributing them evenly throughout the batter.
  4. Prepare slow cooker: Spray the slow cooker insert with nonstick spray to prevent sticking during cooking.
  5. Pour batter into slow cooker: Pour the prepared batter into the slow cooker and smooth the top for even baking.
  6. Cook the cake: Cook on high for 2 to 2½ hours. Begin checking around the 2-hour mark to ensure the edges do not overcook or burn.
  7. Add marshmallows topping: Once the cake is fully set and cooked through, evenly sprinkle mini marshmallows all over the top of the cake.
  8. Broil the marshmallows: Carefully remove the slow cooker insert and place it under the oven broiler for 1 to 2 minutes until the marshmallows become golden and toasted. Watch closely to prevent burning.
  9. Finish with extra toppings: After broiling, garnish the cake with additional marshmallows, extra crushed graham crackers, and more chocolate pieces as desired.

Notes

  • Keep a close eye on the cake during cooking to avoid over-browning, especially near the edges.
  • The broiling step is essential for getting that classic toasted marshmallow finish, but watch it carefully as marshmallows can burn quickly.
  • You can customize the toppings with different kinds of chocolate or add nuts for extra texture.
  • Ensure your slow cooker insert is oven-safe before broiling the cake inside it.
  • Leftover cake can be stored covered at room temperature for up to 2 days or refrigerated for longer freshness.
