What Is a Pecan Pie Dump Cake?
A dump cake is a no-mix dessert made by layering ingredients in a baking dish and baking. The name comes from the idea of “dumping” the ingredients into the pan.
This Pecan Pie Dump Cake uses sugar-free syrup, brown sugar-free sweetener, pecans, sugar-free cake mix, and butter. As it bakes, the butter melts into the cake mix and creates a crisp, golden topping.
The pecan filling underneath becomes warm, bubbly, and syrupy. The result is a cross between a pecan pie and a simple cake.
Ingredients You Need
This recipe uses only a few simple ingredients to create a warm, comforting dessert.
Sugar-Free Pecan Filling
- 1 cup brown sugar-free sweetener, divided
- 1 cup sugar-free syrup
- 1/2 cup salted butter, melted and cooled
- 3 large eggs, at room temperature
- 2 tsp vanilla extract
- 3 cups pecan halves, roughly chopped
Sugar-Free Cake Topping
- 1 box sugar-free white or vanilla cake mix
- 3/4 cup salted butter, melted
- 1/2 cup brown sugar-free sweetener
- 1 cup hot water
- 1 cup pecan halves
The pecan filling provides sweet, nutty flavor. The cake mix and butter create the buttery, golden topping. Hot water helps create the gooey caramel-like filling as it bakes.
How to Make Sugar-Free Pecan Pie Dump Cake
This recipe is extremely easy to prepare. The key is to layer the ingredients and let the oven do the work.
Prepare the Oven
Preheat the oven to 350°F.
Generously grease a 9×13-inch baking dish.
Make the Pecan Filling
Add 1 cup brown sugar-free sweetener, sugar-free syrup, melted butter, eggs, and vanilla extract to a medium bowl.
Whisk until smooth and fully combined.
Stir in the chopped pecans.
Spread the pecan mixture evenly into the prepared baking dish.
Add the Cake Topping
Sprinkle the dry sugar-free cake mix evenly over the pecan filling.
Drizzle the melted butter evenly over the cake mix.
Sprinkle the remaining 1/2 cup brown sugar-free sweetener over the butter.
Slowly pour the hot water over the entire surface.
Do not stir the layers together.
Sprinkle the remaining pecan halves evenly over the top.
Bake
Bake for 35 to 40 minutes, until the topping is golden brown.
The center should still have a slight jiggle when removed from the oven because it will continue to set as it cools.
Let the dessert cool completely before slicing.
Serve
Serve warm for a soft and gooey texture.
Chill before serving for firmer, cleaner slices.
Add sugar-free whipped topping or homemade vanilla cream if desired.
Texture and Flavor
This pecan pie dump cake has a soft, gooey pecan filling underneath and a buttery, golden, slightly crisp topping. The filling is warm and syrupy, with deep caramel and vanilla notes.
Toasted pecans add crunch and a nutty, buttery flavor that makes it taste like classic pecan pie. The cake topping is tender and slightly sweet, which pairs perfectly with the flowing filling.
Served warm, it feels like a rich, comforting dessert that is perfect for any occasion.
Tips for the Best Results
A few small details can help your dump cake turn out perfectly every time.
Cool the Butter Before Mixing
Let the melted butter cool before mixing it with the eggs to keep the filling smooth. Hot butter can cook the eggs.
Chop the Pecans for the Filling
Chop the pecans for the filling so every serving has an even nutty texture. Whole pecans can make slicing difficult.
Do Not Stir the Layers
Do not stir after adding the cake mix, butter, and water. The separate layers create the gooey filling and golden topping.
Avoid Overbaking
Avoid overbaking because the center should remain slightly soft when the dessert comes out of the oven. It will continue to set as it cools.
Let It Cool Fully
Let the cake cool fully so the filling can set properly. This makes for cleaner slices.
Easy Variations
This recipe is easy to customize with different flavors, toppings, and additions.
Add Bourbon Flavor
Add 1/2 teaspoon of bourbon extract or a splash of sugar-free bourbon flavoring to the filling for a grown-up twist.
Add Chocolate
Sprinkle a few sugar-free dark chocolate chips over the pecans before baking for a chocolate-pecan version.
Add Coconut
Sprinkle unsweetened shredded coconut over the top before baking for a tropical touch.
Use Walnuts
Replace the pecans with walnuts for a different nutty flavor.
Add Cinnamon
Add a pinch of ground cinnamon to the filling for a warmer spice note.
Serving Ideas
This dump cake is best served warm. A dollop of sugar-free whipped topping or a scoop of sugar-free vanilla ice cream makes it feel extra special.
Extra toasted pecans add crunch and visual appeal. It is perfect for holiday desserts, family dinners, potlucks, or any time you want a cozy, comforting treat.
Storage Tips
Store leftovers covered at room temperature for up to 3 days or in the refrigerator for up to 1 week.
Reheat individual portions gently in the microwave or warm the whole dish in the oven at 350°F until heated through.
The filling will thicken as it cools. Reheating helps it become gooey again.

Common Mistakes to Avoid
A few simple mistakes can affect the texture of a dump cake.
Using Hot Butter in the Filling
If the butter is too hot, it can cook the eggs. Let it cool before mixing.
Stirring the Layers
Stirring the filling, cake mix, and water together will prevent the gooey filling from forming. Keep the layers separate.
Overbaking
Bake only until the topping is golden brown and the center has a slight jiggle. Overbaking can make the filling too thick.
Serving Too Soon
Let the dump cake cool fully before slicing. This allows the filling to set so it is easier to scoop and serve.
Using a Small Pan
A pan smaller than 9×13 inches can cause the dessert to overflow in the oven.
FAQ
Can I make this ahead of time?
Yes. You can assemble and bake it ahead, then reheat gently before serving. The filling may thicken as it cools but will loosen when warmed.
Can I freeze pecan pie dump cake?
Yes. Cool completely, then cover and freeze for up to 2 months. Thaw in the refrigerator and reheat before serving.
Can I use regular sugar?
Yes, but it will no longer be sugar-free. Use regular brown sugar and syrup in place of the sugar-free versions if preferred.
Why is my filling too thin?
It may need a few more minutes in the oven, or it may thicken more as it cools. Let it rest fully before serving.
Can I use a different nut?
Yes. Walnuts, hazelnuts, or a mix of nuts can work well in place of pecans.
