Pecan dump cake is one of those magical desserts that feels like a cross between a cobbler, a pecan pie, and a cake, but with way less effort than you’d expect for something so indulgent.

It’s incredibly simple to throw together—no mixers, no complicated techniques, and no stress. If you’re looking for a dessert that delivers maximum flavor with minimal fuss, this one’s a keeper.
A sweet memory with pecan desserts
Growing up, my family had a serious love for pecan desserts. Every holiday season, my grandma would bake her famous pecan pie, and the whole house would smell like toasted nuts and warm caramel. I can still picture her, humming softly, cracking pecans by hand while sharing bits of wisdom about life (and dessert). Years later, when I first stumbled across this dump cake recipe, I was immediately reminded of her. It felt like a modern twist on a classic family tradition. The best part? The recipe doesn’t require her legendary pie-making skills—it’s as simple as mixing, layering, and baking. Every time I make it, I’m reminded of those cozy holiday gatherings, but with a much easier cleanup.
The story behind pecan dump cake
Dump cakes have been a staple in home kitchens for decades, especially in the U.S. They gained popularity for their ease—everything is essentially “dumped” into a pan—and their ability to satisfy a sweet tooth without dirtying a ton of dishes. The pecan version takes inspiration from the rich, nutty flavors of pecan pie, one of the most iconic Southern desserts. Combining that traditional filling with the simplicity of a dump cake makes this recipe a modern classic. It’s evolved into a crowd-pleasing dessert perfect for potlucks, family dinners, and holiday celebrations.
Let’s talk ingredients: sweet, nutty, and versatile
Dark brown sugar
Dark brown sugar brings a deep molasses flavor that’s essential to this cake’s pecan-pie-inspired filling. If you’re out of dark brown sugar, you can use light brown sugar in a pinch, though the flavor will be slightly less robust. Look for fresh, soft sugar that crumbles easily when squeezed for the best results.
Dark corn syrup
This keeps the filling gooey and rich, giving it that signature pecan pie consistency. If you don’t have dark corn syrup, maple syrup or honey can be used as substitutes, though they’ll alter the flavor slightly. Dark corn syrup provides a balanced sweetness that pairs beautifully with the nuts.
Salted butter
Butter does double duty here—both in the pecan filling and to moisten the cake mix topping. I always use salted butter for that extra depth of flavor, but unsalted works too; just add a pinch of salt. Pro tip: Let the butter cool slightly after melting so it doesn’t scramble the eggs when mixed.
Pecans
Pecans are the star of this recipe. Toasted, buttery, and slightly sweet, they give the dessert its signature crunch and flavor. When buying pecans, look for ones with a rich, nutty aroma and no signs of discoloration or bitterness. Walnuts can work as a substitute, but there’s something undeniably special about pecans.
White cake mix
This creates the perfect golden topping. Any standard boxed white cake mix will do, but you can experiment with yellow cake mix for a slightly richer flavor. Gluten-free cake mix works well too if you’re catering to dietary restrictions.
Hot water
Though it seems unusual, pouring hot water over the top layer is key. It helps hydrate the cake mix and create that gooey, caramelized layer as it bakes.
Caramel topping (optional)
If you’re feeling fancy, a drizzle of caramel on top adds a luxurious finishing touch.

Kitchen gear: the essentials
For this recipe, you don’t need much, which is part of the appeal:
- 9×13 baking dish: The perfect size for this cake. If you don’t have one, a similarly sized casserole dish will work. Just be sure to grease it well.
- Mixing bowl: A medium-sized mixing bowl is all you need to prepare the pecan filling.
- Whisk or spatula: For stirring together the filling ingredients.
- Measuring cups and spoons: Precise measurements ensure the filling sets up properly.
If you don’t own a whisk, you can use a fork to combine the filling ingredients—it might take a little longer, but it works just fine.
Step-by-step: making your pecan dump cake
- Prep your baking dish and oven
Preheat your oven to 350°F and generously spray a 9×13 baking dish with nonstick spray. Trust me, you don’t want to skip the greasing—it’ll make cleanup so much easier later. - Mix the pecan filling
In a medium mixing bowl, combine 2 cups of dark brown sugar, dark corn syrup, ½ cup of melted butter, eggs, and vanilla. Whisk it all together until smooth, then stir in 3 cups of pecan halves. The mixture should look thick and glossy. - Layer the filling in the pan
Pour the pecan mixture evenly into your greased baking dish, making sure the nuts are distributed throughout. - Add the dry cake mix
Sprinkle the entire packet of cake mix over the pecan filling. Don’t stir—just let it sit on top like a fluffy layer of snow. - Drizzle butter and sugar
Pour the remaining ¾ cup of melted butter over the dry cake mix, then sprinkle ¾ cup of dark brown sugar on top. - Add hot water and pecans
Carefully pour 1 cup of hot water over the top, tilting the pan gently to help spread it out. Scatter the remaining 1 cup of pecan halves over the surface. - Bake to golden perfection
Pop the dish in the oven and bake for 35-40 minutes. The top should be golden brown, and the center will jiggle slightly (this is normal!). Check on it around the 30-minute mark, as ovens can vary. Let it cool completely before serving.

Fun variations to try
- Gluten-free version: Use a gluten-free white cake mix. It works just as well, and your gluten-sensitive friends will thank you.
- Vegan twist: Swap the butter with vegan butter, the eggs with flax eggs (1 tablespoon flaxseed meal + 2.5 tablespoons water per egg), and ensure your cake mix is dairy-free.
- Seasonal flavors: Add a teaspoon of cinnamon and nutmeg to the pecan filling for a warm, fall-inspired dessert.
- Chocolate pecan cake: Use a chocolate cake mix instead of white for a decadent twist.
- Coconut flair: Stir shredded coconut into the filling or sprinkle it on top for a tropical take.
How to serve and garnish
This pecan dump cake shines on its own, but adding a little flair never hurts. Serve it warm or at room temperature with a scoop of vanilla ice cream or a dollop of whipped cream. A drizzle of caramel sauce over each serving takes it to another level. For presentation, I like to scatter a few toasted pecans over the top for extra crunch and visual appeal.
Perfect beverage pairings
- Coffee or espresso: The bold flavors of coffee pair beautifully with the sweetness of the cake.
- Spiced chai tea: The warm spices complement the pecans perfectly.
- Vanilla almond milk: A creamy, nutty drink that echoes the flavors of the dessert.
- Iced tea: A refreshing choice, especially if you’re serving this cake at a summer gathering.
- Hot cocoa: For a cozy winter pairing, hot chocolate with a dollop of whipped cream is delightful.
Storing and reheating tips
If you’ve got leftovers (lucky you!), cover the pan tightly with plastic wrap or transfer the cake to an airtight container. It’ll stay fresh in the fridge for up to 4 days. When reheating, pop a slice in the microwave for about 20-30 seconds to bring back its gooey warmth. Avoid freezing this cake—the texture doesn’t hold up well.
Adjusting for different servings
To feed a smaller group, halve the ingredients and bake in an 8×8 dish. Keep the bake time roughly the same but start checking for doneness at 25 minutes. For a crowd, double the recipe and bake in two 9×13 pans. Just remember, this cake is rich—a little goes a long way!
Potential hiccups (and how to fix them)
- Too dry? Make sure you evenly pour the hot water over the cake mix and don’t skimp on the butter.
- Runny center? It’s normal for the center to be slightly jiggly, but if it’s overly wet, bake it for an additional 5-10 minutes.
- Uneven topping? Tilt the pan gently after adding the water to help distribute moisture.
Go ahead, give it a try!
This pecan dump cake is the perfect combination of easy and impressive. Whether you’re making it for a holiday gathering, a potluck, or just because you’re craving something sweet and nutty, it’s bound to become a favorite. Experiment with your own twists and serve it with pride—you really can’t go wrong.

Frequently asked questions

2. Can I make this ahead of time?
Yes, it tastes even better the next day. Just store it in the fridge and reheat individual portions before serving.

Warm water works too—just make sure it’s not cold, as it needs to help dissolve the sugar and hydrate the cake mix.
