Can I substitute the Heath bars for something else?

Absolutely. Chopped toffee (or other chocolate‑toffee bars) work, or even chopped pecans for crunch. Just adjust sweetness if needed.

What if I don’t have Cool Whip?

You can use whipped cream, mascarpone whipped with a bit of sugar, or even vanilla frosting thinned slightly with milk. It won’t be identical , but it’ll still be heavenly.

How long does it keep?

Stored in the refrigerator, covered tightly, this dessert stays good for up to 3–4 days. Texture softens a little after the first day, but flavors deepen nicely.

Can I double this recipe?

Depends on the size of your slow cooker. If you have a large one (6‑8 quart), you might fit a double batch. But cooking time might stretch a bit—add 30‑45 minutes and test with a toothpick for doneness.

Instructions

In a large bowl, combine the cake mix, eggs, water, and melted butter. Mix until smooth.
Spray the inside of the slow cooker with nonstick spray. Pour in the batter and spread evenly.
Cover and cook on high for 2 hours. Do not lift the lid during cooking.
Once done, poke holes in the cake using the end of a wooden spoon.
Pour sweetened condensed milk and ½ cup of caramel topping over the cake, letting it soak into the holes.
Allow the cake to cool slightly, then refrigerate for at least 2 hours or overnight.
Once chilled, top with Cool Whip, sprinkle with chopped Heath bars, and drizzle with caramel and chocolate sauce.
Scoop and serve. Enjoy!

Notes

Don’t skip chilling—this helps the cake set and enhances flavor.
For cleaner scoops, refrigerate overnight.
Feel free to swap Heath bars for toffee bits or chopped nuts.
