Dark brown sugar and corn syrup provide a sweet, caramel-like flavor, while the pecan halves deliver nuttiness and crunch. White cake mix offers a soft base, and the hot water transforms it into a moist cake, ensuring the perfect texture.

For this recipe, you’ll need:

  • 1½ cups of dark brown sugar, packed (divided into 1 cup and ½ cup)
  • 1 cup of dark corn syrup (I used dark Karo syrup)
  • 1¼ cup of salted butter, (divided into ½ cup and ¾ cup) melted, and cooled 
  • 3 large eggs, room temperature
  • 2 teaspoons of pure vanilla extract
  • 4 cups of pecan halves (divided into 3 cups and 1 cup)
  • 1 (15.25-ounce or 432-gram) box of white cake mix
  • 1 cup of hot water
  • Caramel topping, optional 

Substitutions and Additions

WHITE CAKE MIX: If you’re feeling adventurous, try substituting the white cake mix with yellow cake mix, butter pecan cake mix, or even a spice cake mix for a unique twist on flavors.

DARK CORN SYRUP: If you don’t have dark corn syrup on hand, a caramel sundae topping can step in to maintain that rich sweetness.

TOPPING: Take your pecan dump cake to the next level with a little bit of caramel drizzle over the top for an extra layer of indulgence.

How To Make This Pecan Dump Cake Recipe

The beauty of a dump cake is just how easy they are to make. Don’t over think it! This recipe requires you to mix together a simple filling, then dump a few things on top.

Bake, and you’re done! Let’s have a look at the step-by-step instructions together.

STEP ONE: Preheat the oven to 350°F. Generously spray a 9×13 (or 13×9) baking dish with nonstick cooking spray.

STEP TWO: Add one cup of dark brown sugar, dark corn syrup, ½ cup of melted butter, eggs, and vanilla to a medium-sized mixing bowl (2-3 quarts). Whisk to combine.

STEP THREE: Stir in the three cups of pecan halves. Evenly spread the pecan mixture into the sprayed baking dish.

Bottom row: Two images labeled “Add the pecans & pour into the dish.” showing whole pecans mixed into the batter, then the mixture poured into a glass baking dish, ready for baking.

STEP FOUR: Sprinkle the dry cake mix over the pecan filling. 

STEP FIVE: Drizzle the remaining ¾ cup of melted butter over the dry cake mix.

STEP SIX: Sprinkle the remaining ½ cup dark brown sugar over the butter layer.

STEP SEVEN: Pour the hot water over the top of the cake mix and butter. Do not mix. You can carefully tilt the cake pan to distribute the water over the cake mix. 

STEP EIGHT: Sprinkle the remaining one cup of pecan halves over the cake mix and water layer.

STEP NINE: Bake for 35-40 minutes or until golden brown. Because all ovens bake differently, check on the cake at the 30-minute mark. Allow the cake to cool completely before serving.

Step-by-step collage showing how to assemble pecan dump cake:
Top left: Glass baking dish filled with dry cake mix and drizzled melted butter, labeled “Cake Mix & Butter.”
Top right: Brown sugar sprinkled over cake mix, with water being poured in, labeled “Brown Sugar & Water.”
Bottom left: Whole pecans arranged on top of the mixture, labeled “Pecan Halves.”
Bottom right: Fully baked pecan dump cake, golden brown with toasted pecans on top, labeled “Bake!”

Be very careful when placing the cake in the oven due to the hot water on top of the cake.

Our Recipe Developer Says: “At 38 minutes, this dump cake still had a slight jiggle in the middle. I went ahead and took it out, and it firmed up as it cooled.

How To Serve

Scoop this gooey pecan dump cake right out of the pan. Its wonderfully rich flavor is the perfect way to end a family dinner.

For an easy serving idea, you can’t go wrong with our homemade vanilla ice cream. Or whip up some whipped cream and drizzle with caramel sauce.

Pure indulgence.

Need a sweet afternoon treat? Pair a scoop of pecan dump cake with a steaming cup of coffee (or a cool caramel latte) for a cozy afternoon treat.

Storage

MAKE AHEAD: You can prepare the pecan dump cake filling ahead of time, cover it tightly, and store it in the fridge for up to 24 hours before baking. Then, just assemble the layers and bake.

IN THE FRIDGE: If you have leftovers of this quick dessert, cover the cake and store it at room temperature for up to three days. For longer storage, place it in the fridge for up to a week.

IN THE FREEZER: To freeze, wrap individual portions in plastic wrap and place them in an airtight container. Freeze for up to two months. 

To serve, thaw overnight in the refrigerator, and then reheat in the oven at 350°F until warm.

REHEATING: Reheat leftover slices in the microwave for a quick warm-up, or place them in a preheated oven at 350°F for about ten minutes for that freshly baked taste.
