Name: Gooey Pecan Pie Dump Cake Recipe
Prep time: 10 min
Cook time: 50 min
Total time: 60 min
Ingredients: 1 cup light corn syrup; 1 cup packed light brown sugar; 3 large eggs; 1/4 cup unsalted butter, melted; 1 tsp vanilla extract; 1/4 tsp fine sea salt; 2 cups pecan halves or roughly chopped pecans, plus a small handful for topping; 1 box (15.25 oz) yellow cake mix; 3/4 cup cold unsalted butter, sliced into thin pats

This pecan pie dump cake gives you all that sticky, nutty, buttery pecan pie flavor with none of the rolling pin work. Just a quick whisk, a few layers, and the oven does the rest.

Even better, it bakes up with a crisp golden top and a gooey pecan-filled base that tastes like it took all afternoon. A dessert this good with this little effort tends to disappear fast.

What Makes This One So Good

The bottom layer is soft and almost custardy, packed with brown sugar, corn syrup, and plenty of toasted pecans. It sets up just enough to slice but stays spoonable and rich.

On top, a yellow cake mix bakes into a buttery, crunchy crust that breaks with a fork. The contrast between the crisp top and the tender filling is why this dump cake shows up at potlucks, Thanksgiving, and random Tuesday nights.

I like that it needs no mixer and no chilling. The whole thing comes together in one bowl before you even need to preheat, and it fills the kitchen with the same warm, nutty smell as a classic pecan pie.

Ingredients

1 cup light corn syrup: keeps the filling smooth and gooey, not thick or grainy
1 cup packed light brown sugar: dark brown sugar gives a deeper caramel note if you have it
3 large eggs: let them sit out so they blend evenly without shocking the melted butter
1/4 cup unsalted butter, melted: cool it slightly so you don’t scramble the eggs when you whisk
1 tsp vanilla extract
1/4 tsp fine sea salt: balances the sweetness without making it salty
2 cups pecan halves or roughly chopped pecans: plus a small handful to scatter over the top
1 box (15.25 oz) yellow cake mix: standard dry mix, no ingredients added
3/4 cup cold unsalted butter, sliced into thin pats: straight from the fridge is best

Variations / Substitutions

Swap the corn syrup: you can use dark corn syrup for a deeper, almost molasses like taste, but light keeps the appearance classic.
Use a different cake mix: butter pecan or white cake mix both work, the yellow just gives the most butter forward contrast.
Change the nuts: walnut halves or a mix of pecans and almonds will toast up nicely, though pecans give you that true pie flavor.
Try browned butter for the filling: brown the 1/4 cup melted butter first, let it cool a bit, then whisk it in for a nuttier base.
Make it dairy free: a good plant based butter stick works for both the melted butter in the filling and the cold pats on top.

How to Make Gooey Pecan Pie Dump Cake

Step 1: Mix the Pecan Filling

Preheat the oven to 350°F (175°C) and grease a 9×13 inch baking dish with butter or nonstick spray. In a large bowl, whisk together the 1 cup corn syrup, 1 cup brown sugar, the 3 eggs, the 1/4 cup melted butter, vanilla, and salt until the mixture is smooth and no streaks of egg white remain, about 1 minute of brisk whisking.

Once it looks glossy and blended, fold in the 2 cups of pecans so they are evenly coated. Pour the whole thing into the greased dish and spread the nuts into an even layer. The mixture will be thin at this stage but it thickens as it bakes.

Step 2: Sprinkle the Cake Mix

Open the box of yellow cake mix and sprinkle it dry, straight from the package, over the pecan mixture. Use a spoon or your fingers to break up any large clumps and work across the surface so the mix covers the filling completely to the edges. No stirring, no mixing, just an even layer.

This dry layer will absorb moisture from the filling below and turn into a soft, cakelike texture in some spots and a crisp topping in others. Leaving gaps causes bare pockets, so take an extra 30 seconds to spread it out.

Step 3: Arrange the Butter and Pecans

Take the 3/4 cup cold butter pats and distribute them evenly over the surface of the dry cake mix. Try to cover most of the top so every bit of mix gets some fat as it melts. Then scatter the reserved handful of pecans over the butter.

As the cake bakes, those cold butter slices slowly melt and seep into the mix, creating golden puddles and flaky patches. The extra pecans on top will toast and turn fragrant and crunchy.

Step 4: Slice and Serve Warm

Bake for 45 to 50 minutes, until the top is deeply golden and the filling bubbles thickly around the edges. The center should jiggle only slightly, not slosh. Let the dish rest on a wire rack for at least 15 minutes so it can set up before you slice.

Run a knife around the edge, then cut into squares and lift them out with a spatula. A scoop of vanilla ice cream melting into the warm slices is never a bad idea. Serve while it is still warm and the top is crisp.

A Few Notes for the Best Dump Cake

Use butter straight from the fridge. Room temperature butter melts into a greasy layer instead of forming those golden, flaky pockets on top of the cake mix.
If your pecans are untoasted, spread them on a sheet pan and toast at 350°F for 6 to 8 minutes before you start. That quick step deepens the nutty flavor throughout the whole dessert.
For the cleanest slices, let the cake cool completely, then rewarm individual portions in a low oven or microwave. It holds its shape better once fully set.
This recipe easily doubles for a crowd. Use a larger deep dish pan and add about 10 extra minutes to the bake time, watching for the same dark golden top and bubbling edges.

Storing Leftovers

Refrigerate: Cover the dish tightly or transfer squares to an airtight container. It keeps well in the fridge for up to 4 days.
Reheating: A 20-second zap in the microwave brings back the gooey texture, or warm slices in a 300°F oven for 10 minutes to revive the crisp top.

Frequently Asked Questions

Can I use dark corn syrup instead of light?

Yes, dark corn syrup tastes richer and a bit more like molasses. The color will be deeper and the flavor a touch less sweet, which some people prefer.

What if I only have pecans in pieces, not halves?

Chopped pieces work just fine. The nuts still soften inside the filling and toast on top. You can even leave them whole if they are small.

How do I keep the middle from being underbaked?

Make sure the butter pats are evenly spaced so the cake mix hydrates uniformly. Also, let the cake rest the full 15 minutes out of the oven; the carryover heat finishes setting the center.

Can I assemble this ahead and bake it later?

The dry cake mix absorbs moisture from the filling if it sits unbaked, so it is best to layer everything right before it goes in the oven. You can whisk the filling together a day ahead and keep it covered in the fridge.
