- 15.25 oz. Devil’s food cake mix: The foundation of this cake, providing a rich, chocolatey flavor and moist texture.

- 8 oz Cool Whip (thawed): Provides a light, airy contrast to the dense cake.

How to Make Slow Cooker Better Than Sex Cake
Step 1: Prepare the Batter
Begin by blending the devil’s food cake mix, eggs, water, and melted butter in a large bowl. Mixing until smooth is key because it ensures your cake will bake evenly in the slow cooker. The batter’s smooth texture is what makes the final cake pillow-soft and moist.
Step 2: Get Your Slow Cooker Ready
Spray the slow cooker insert generously with cooking spray. This step prevents the cake from sticking and makes removing it effortless after cooking. Once prepped, pour in the batter and smooth it out evenly to avoid uneven cooking spots.
Step 3: Cook on High
Cover your slow cooker and set it on high for exactly 2 hours. Patience here pays off—do not open the lid during cooking as it lets the heat escape, which can affect texture. The slow cooking method results in an incredibly moist cake that oven baking just can’t replicate.
Step 4: Add the Gooey Goodness
When the cake is finished, use the handle end of a spoon to poke holes all over the surface. Then pour the sweetened condensed milk and half a cup of caramel topping directly over the cake, allowing it to seep deep into those holes. This step transforms the cake into a rich, gooey masterpiece that lives up to its name.
Step 5: Cool and Chill
Remove the slow cooker insert and let it cool until the bottom feels slightly warm to the touch. Then pop it into the refrigerator for at least two hours or ideally overnight. Cooling lets the flavors meld and the cake set perfectly for serving.
Step 6: Final Assembly
Once chilled, spread the Cool Whip evenly on top. Sprinkle the chopped Heath bars over the whipped topping, then drizzle extra caramel and chocolate sauce for an irresistible finish. This layered combination makes every bite a delicious adventure of flavors and textures.
How to Serve Slow Cooker Better Than Sex Cake

Garnishes
Simple yet impactful garnishes can elevate this dessert. Consider adding a few extra Heath bar pieces, a sprinkle of sea salt to balance sweetness, or even some fresh berries for a pop of color and freshness. Each garnish adds a new dimension to this already decadent cake.
Side Dishes
This Slow Cooker Better Than Sex Cake is rich, so serving it alongside lighter sides like fresh fruit salad, a scoop of vanilla ice cream, or a small dollop of lightly sweetened whipped cream can beautifully balance the sweetness and richness, making the dessert experience even more memorable.
Creative Ways to Present
For parties or special occasions, consider serving the cake straight from the slow cooker to keep it warm and inviting. Alternatively, cut into neat squares and layer individual servings in clear glass cups with layers of whipped cream and caramel sauce for a stunning parfait-style presentation.
Make Ahead and Storage
Storing Leftovers
Store any leftover Slow Cooker Better Than Sex Cake in an airtight container in the refrigerator. It will stay fresh and moist for up to 4 days. Keeping it chilled preserves the whipped topping and ensures the caramel-soaked cake stays luscious.
Freezing
You can freeze this cake by wrapping leftover portions tightly in plastic wrap and placing them in a freezer-safe container. Freeze for up to 3 months. Thaw overnight in the refrigerator before serving for the best texture and flavor.
Reheating
If you want to enjoy your cake warm, gently reheat individual portions in the microwave for about 20-30 seconds. Avoid reheating the entire cake at once, as this can melt the Cool Whip and alter the texture.
FAQs
Can I use a different cake mix for this recipe?
Absolutely, though the devil’s food cake mix gives the rich chocolate flavor essential to this dessert’s signature taste. Using another mix will still work but will change the cake’s flavor profile.
Do I have to use a slow cooker?
The slow cooker is what makes this cake uniquely moist and tender, but you could bake it in the oven if necessary. Adjust baking times accordingly and be sure to poke holes for the condensed milk soak when warm.
How important is it to chill the cake before adding the toppings?
Chilling the cake is crucial for setting the infused condensed milk and caramel inside and for stabilizing the structure. It also helps the Cool Whip topping hold its shape better before serving.
Can I substitute Cool Whip with homemade whipped cream?
Yes, homemade whipped cream can be a delicious alternative and adds a fresh, creamy flavor. Just whip heavy cream with a bit of sugar until stiff peaks form and spread it on chilled cake before adding toppings.
What can I use instead of Heath bars?
If you want a different crunch, crushed butterfingers, toffee bits, or even chopped pecans work wonderfully. Each will bring its own twist to the texture and flavor of the cake.
