Ingredients You’ll Need
These ingredients are wonderfully simple yet each one plays a critical role in making this cake irresistibly moist, flavorful, and textured from top to bottom. They come together to balance sweetness, richness, and crunch.
- 15.25 oz. Devil’s food cake mix: The base for a rich and fudgy chocolate flavor that melts in your mouth.
- 3 large eggs: These provide the structure and moisture your cake needs to rise and stay tender.
- 1 cup water: Helps create the perfect batter consistency while keeping the cake light.
- ½ cup unsalted butter (melted): Adds a velvety richness and moistness that’s unbeatable.
- 14 oz. can sweetened condensed milk: Pouring this on top after cooking infuses the cake with creamy sweetness that soaks deep inside.
- ½ cup caramel topping (plus extra for drizzling): Contributes luscious caramel notes and a beautiful sticky texture.
- 8 oz Cool Whip (thawed): Whipped topping gives an airy, creamy finish that lightens up the sweetness.
- 3 Heath bars (chopped; 4.2 ounces): The crunchy bits of toffee and chocolate add the perfect contrast to the gooey cake.

How to Make Slow Cooker Better Than Sex Cake
Step 1: Mix the Batter
In a large bowl, combine your devil’s food cake mix, three eggs, one cup of water, and the melted unsalted butter until the batter is smooth and evenly mixed. This simple batter is the foundation of your cake, delivering a depth of chocolate flavor with a moist and tender crumb that’s just waiting to be slow-cooked to perfection.
Step 2: Prepare the Slow Cooker
Spray the inside of your slow cooker with cooking spray. This crucial step ensures the cake doesn’t stick to the sides and comes out cleanly once it’s cooked. Pour your smooth batter into the slow cooker and spread it out evenly with a spatula for consistent cooking.
Step 3: Slow Cook the Cake
Cover your slow cooker and set it to cook on high for about two hours. It is important not to open the lid during cooking, as steam and heat are key to letting your cake rise perfectly and maintain its moisture. After cooking, the cake will be soft, rich, and begging for the next step.
Step 4: Create the Magic with Condensed Milk and Caramel
Using the back of a spoon, gently poke holes all over the cooked cake. These holes allow the sweetened condensed milk and caramel topping to seep deeply into the cake, infusing each bite with extra sweetness and gooeyness. Pour the 14 oz. can of condensed milk evenly over the cake, followed by ½ cup of caramel topping. Then remove the slow cooker insert and let it cool to room temperature.
Step 5: Chill the Cake
Once the insert feels cool to the touch, place it in the refrigerator for at least two hours or ideally overnight. This chilling step helps the cake set up and the flavors to meld beautifully, making it even more indulgent and satisfying.
Step 6: Add the Final Toppings
When you’re ready to serve, spread a generous layer of thawed Cool Whip over the chilled cake. Sprinkle the chopped Heath bars evenly on top, generously drizzle caramel and chocolate sauces, creating an enticing final layer that pleases both the eyes and taste buds.
Step 7: Serve and Enjoy!
Use a large spoon to scoop out portions of this divine dessert. Each bite brings a fantastically rich combination of creamy, crunchy, chocolaty, and caramel flavors that will have everyone asking for seconds. Trust me, this Slow Cooker Better Than Sex Cake truly delivers a melt-in-your-mouth experience every time.

Garnishes

Creative Ways to Present

Make Ahead and Storage
Storing Leftovers
Store any leftover Slow Cooker Better Than Sex Cake in an airtight container in the fridge. It will stay fresh and moist for up to four days, allowing you to enjoy this decadent dessert several times without losing any flavor or texture.
Freezing
If you want to save some for later, freeze the cake in portions, wrapped tightly in plastic wrap and aluminum foil or in freezer-safe containers. This way, your delicious cake can last up to 2 months while retaining its indulgent taste.
Reheating
To reheat, thaw the cake in the refrigerator overnight and then warm individual servings in the microwave for about 20-30 seconds to bring back that fresh-baked feeling. Add fresh drizzles of caramel or chocolate sauce after warming for a perfect treat.
FAQs
Can I use a different cake mix for this recipe?
Absolutely! While devil’s food cake gives the richest chocolate flavor, you can experiment with chocolate fudge or even spice cake for unique twists. Just keep in mind that the overall flavor will shift depending on the base.
Do I have to use a slow cooker for this cake?
This recipe is designed specifically for slow cooker use. Cooking it in a conventional oven would require a different method and timing. The slow cooker ensures the cake stays moist, tender, and evenly cooked.
What if I don’t have Cool Whip? Can I use something else?
You can substitute Cool Whip with homemade whipped cream or any other whipped topping you prefer. Just make sure it’s thawed and spreadable for the best texture on top of the cake.
Is it okay to skip the Heath bars?
Though the Heath bars add excellent crunch and toffee flavor, you can substitute with chopped nuts, crushed chocolate candies, or even omit entirely if you prefer a smoother texture.
How long should I cook the cake if I want a firmer texture?
If you prefer a less gooey, firmer cake, you can try cooking the cake on low for a longer time, around 3 to 4 hours, monitoring it closely to avoid drying out. The two-hour high cook is ideal for the classic soft, luscious texture.
