Pecan Pie Dump Cake Recipe With Cake Mix: Gooey Pecan Filling Meets Moist Cake Layers

This dessert brings together the rich, gooey filling of pecan pie with the ease of a cake mix. I developed this method after finding my grandmother’s vague handwritten notes about “that pecan cake thing.”

With just a few ingredients and minimal effort, you’ll create a moist cake layered with a caramelized pecan topping. The cake mix base ensures consistency, while the pecans add that signature Southern charm.

The result is a warm, comforting dessert that’s perfect for gatherings or a cozy night in. The pecans soften into a sticky, sweet layer, while the cake stays tender and flavorful.

No fancy techniques—just simple steps for a dish that tastes like it came from a bakery. Here’s how to make it.

Ingredients for Pecan Pie Dump Cake Recipe with Cake Mix

Short list. Big flavor. Probably have most of this already.

The pecans are the star here. Fresh pecan halves from a bulk bin or Trader Joe’s are ideal—avoid the pre-chopped kind (they can taste stale). I always grab extra since they keep well in the freezer. The cake mix is your shortcut—Betty Crocker or Duncan Hines both work great. Look for the 15.25 oz boxes, which are the standard size.

No heavy cream? Whole milk with a splash of melted butter gets you close. Light brown sugar is ideal, but dark brown adds a deeper molasses note if that’s what you’ve got. If you’re out of vanilla, a pinch of cinnamon or nutmeg can add some warmth. The butter needs to be unsalted so you can control the saltiness—Land O’Lakes is my go-to.

This keeps 3-4 days at room temperature in an airtight container. The pecan topping softens over time but stays gooey. For longer storage, freeze slices for up to 3 months (thaw at room temp before serving).

Step-by-Step Instructions for Pecan Pie Dump Cake

This method layers pecan pie filling with cake mix for a dessert that bakes itself into perfection.

Step 1: Prepare the Pecan Pie Filling Base

Preheat your oven to 350°F. In a 9×13-inch baking dish, combine the 2 cups Pecan Halves, 1 cup Light Brown Sugar, 1 cup Heavy Cream, 0.5 cup Unsalted Butter (melted), 1 tsp Vanilla Extract, 1 tsp Ground Cinnamon, and 0.25 tsp Salt. Stir until the brown sugar starts to dissolve and everything is well coated.

The mixture should look glossy and slightly bubbly around the edges. This is your pecan pie layer—rich, gooey, and packed with buttery pecan flavor. Spread it evenly across the bottom of the dish so every bite gets that caramelized goodness.

Step 2: Mix the Cake Batter

In a separate bowl, whisk together the 1 box Yellow Cake Mix, 2 whole Large Eggs, 0.33 cup Vegetable Oil, and 1 cup Water until smooth and lump-free. The batter should be thick but pourable—like pancake batter but slightly denser.

I’ve found that using a fork works better than a spoon here—it breaks up any clumps quickly without overmixing. Let the batter rest for 2 minutes while you check the oven temperature. This brief pause helps the cake mix hydrate fully for a perfectly moist texture.

Step 3: Layer and Bake Without Stirring

Gently pour the cake batter over the pecan mixture in the baking dish. Here’s the thing—don’t stir or mix the layers together. Simply let the batter spread naturally over the filling. The magic happens as it bakes, with the cake layer rising to the top and the pecan filling sinking to create that signature dump cake effect.

I always tap the dish lightly on the counter once or twice to release any large air bubbles in the batter. Then slide it into the preheated oven and bake for 40-45 minutes, or until the top is golden brown and a toothpick inserted into the cake layer comes out clean.

Step 4: Cool and Serve Warm

Remove the dish from the oven and let it cool for 15 minutes before serving. This resting time allows the layers to set slightly, making it easier to portion without everything running together.

You’ll notice the pecan filling bubbles up through the cake in spots—that’s exactly what you want. Serve warm with a scoop of vanilla ice cream or a drizzle of caramel sauce. The contrast between the moist cake and the gooey pecan layer below is what makes this dessert so irresistible.

Essential Equipment for This Recipe

Baking Dish Essentials

For this dessert, a 9×13-inch glass baking dish is ideal. I use my grandmother’s old Pyrex—it distributes heat evenly and lets you watch the caramelized pecans bubble. Avoid metal pans, as they can cause the edges to overcook before the center sets. 💪

Mixing Tools

A simple whisk and mixing bowls (one for filling, one for batter) are all you need. I prefer a fork for the cake batter—it breaks up clumps better than a spoon. No fancy stand mixer required; this is a one-bowl recipe at heart.

Measuring Must-Haves

Keep dry measuring cups for the cake mix and brown sugar, and liquid measures for the cream and oil. A 1-tablespoon measure helps with the vanilla and spices. My grandmother eye-balled everything, but I’ve learned precise measurements prevent mistakes.

Oven Thermometer

Don’t trust your oven’s built-in gauge. A $10 oven thermometer from the grocery store ensures your 350°F is accurate. I hung one in my oven after burning a batch of cookies, and it’s been a game-changer for consistent results.

Serving Supplies

Have a cooling rack ready for the dish after baking. A sharp knife dipped in hot water makes clean slices through the gooey layers. And don’t forget the ice cream scoop—this dessert begs for vanilla on top.

Honestly, the best part is how little equipment you actually need. No special gadgets, just reliable basics. 💛
