When you want a comforting Southern-style bake packed with warm tropical flavors and buttery roasted nuts, multi-layered dump cakes are a hassle-free kitchen classic.

Featuring a creamy coconut base, a self-forming golden butter pecan crust, and a crown of nutty toasted coconut and crunchy pecans, this dessert requires zero advanced baking skills.

Simple Ingredients for a 9×13 Pan Feast

This recipe uses everyday low-sugar convenience staples to create a multi-tiered dessert with minimal effort.

Ingredients

1 can (15 oz) sugar-free cream of coconut (or unsweetened full-fat coconut cream): Forms the rich, liquid coconut base at the bottom of the pan.
1 cup unsweetened shredded coconut: Toasts in the oven to add texture and a nutty flavor.
1 box sugar-free butter pecan cake mix (or sugar-free vanilla cake mix): Acts as the dry crust component that bakes into a golden layer.
1 cup chopped pecans: Provides an authentic Southern crunch and buttery flavor across the top.
1 cup unsalted butter (melted): Drizzled evenly over the dry mix to bind the ingredients into a rich crust.

Step-by-Step Instructions

Follow these two straightforward steps to assemble, bake, and serve your coconut cream pecan cake.

Step 1: Prep and Layer

Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish.
Pour 1 can of sugar-free cream of coconut evenly into the bottom of the prepared dish.
Sprinkle 1 cup of unsweetened shredded coconut evenly over the liquid coconut base.
Add the dry box of sugar-free butter pecan cake mix in an even layer directly over the top. (Do not stir).
Scatter 1 cup of chopped pecans uniformly across the dry cake mix layer.
Drizzle 1 cup of melted unsalted butter as evenly as possible across the entire surface, covering as much of the dry mix and nuts as you can.

Step 2: Bake and Cool

Place the baking dish into the preheated oven and bake for 45 minutes, or until the top is deep golden brown and the edges are bubbling.
Remove from the oven and allow the cake to cool for at least 15 minutes to let the bottom layer set slightly before serving warm.

Pro Tips for Perfect Dump Cake Results

Do Not Stir the Layers: Leaving the layers unmixed is the secret to a successful dump cake. The butter melts down through the dry mix during baking, forming a golden crust over the creamy liquid base.
Drizzle Butter Carefully: Take your time pouring the melted butter to cover as much of the dry cake mix as possible. This minimizes any dry, powdery spots after baking.
Serve Warm: Enjoy a slice warm on its own, or elevate it by serving alongside a scoop of sugar-free vanilla ice cream or a dollop of sugar-free whipped cream.
Watch the Pecans: Pecans toast quickly on the top rack. If you notice them browning too quickly near the end of baking, loosely tent a sheet of aluminum foil over the pan for the last 10 minutes.

Storage and Reheating Guidelines

Refrigeration: Cover leftover cake with foil or plastic wrap and store it in the refrigerator for up to 3 to 4 days.
Reheating: Reheat individual slices in the microwave for 15 to 20 seconds to restore the soft, warm custard-like base.

FAQs

Why shouldn’t I mix the ingredients together?

Stirring the dry cake mix into the liquid destroys the distinct layers. Leaving the cake mix dry on top allows the melted butter to saturate it gradually, forming a tender, crisp cake crust over the coconut layer.

What if I cannot find sugar-free butter pecan cake mix?

You can easily substitute sugar-free vanilla or yellow cake mix! Simply add a dash of ground cinnamon or a teaspoon of pecan extract to the dry mix before layering if you want an extra boost of butter pecan flavor.

Can I use unsweetened full-fat canned coconut milk instead of cream of coconut?

Yes, unsweetened full-fat canned coconut milk works as a great substitute. If using plain coconut milk, you can whisk in 1 to 2 tablespoons of your favorite granulated sugar-free sweetener before pouring it into the dish for added sweetness.

How do I fix dry powdery spots on top?

Dry spots happen when melted butter misses areas of dry flour. If you notice dry patches halfway through baking, gently press them down with a spoon so they absorb the bubbling butter from surrounding areas.
