Ingredients You’ll Need
- 15.25 oz devil’s food cake mix
- 3 large eggs
- 1 cup water
- ½ cup unsalted butter, melted
- 14 oz can sweetened condensed milk
- ½ cup caramel topping, plus extra for drizzling

Step-by-Step Instructions for Slow Cooker Cake
Step 1: Mix the Cake Batter
In a large bowl, combine the devil’s food cake mix, eggs, water, and melted butter. Blend well until smooth and fully incorporated.
Step 2: Prepare the Slow Cooker
Spray the inside of your slow cooker insert generously with cooking spray to prevent sticking. Pour the cake batter into the slow cooker and smooth it into an even layer.
Step 3: Cook the Cake
Cover and cook on high for 2 hours. Avoid opening the lid during cooking to ensure the cake rises and cooks evenly.
Step 4: Add Condensed Milk and Caramel
Once cooked, use the end of a spoon to poke holes all over the cake’s surface. Slowly pour the sweetened condensed milk and ½ cup of caramel topping evenly over the cake, allowing it to seep into the holes.
Remove the slow cooker insert and let the cake cool until the bottom is cool to the touch.
Step 5: Chill the Cake
Place the cake in the refrigerator for at least 2 hours or overnight to set and meld the flavors.
Step 6: Add Whipped Topping and Garnishes
Spread the thawed Cool Whip evenly over the chilled cake. Sprinkle the chopped Heath bars on top, then drizzle generously with caramel and chocolate sauces.
Step 7: Serve and Enjoy
Scoop the cake with a large spoon and serve. The combination of moist cake, creamy topping, crunchy candy, and rich sauces makes each bite pure bliss.
