1¼ cups salted butter, melted and cooled (divided into ½ cup and ¾ cup)

1 cup hot water
Caramel topping (optional, but delicious)

Let’s Get Started

This recipe follows the classic “dump cake” method with just a few small mixing steps to ensure the perfect texture.

Step 1 — Preheat the Oven

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish or line it with parchment paper.

Step 2 — Prepare the Brown Sugar Mixture

In a large bowl, whisk together:

1½ cups dark brown sugar
1 cup dark corn syrup
½ cup melted butter
3 eggs
Vanilla extract

Whisk until smooth and glossy. Fold in 3 cups of pecan halves.

Step 3 — Spread Into the Baking Dish

Pour the mixture into the prepared baking dish and spread evenly.

Step 4 — Add the Dry Cake Mix

Sprinkle the dry white cake mix evenly over the top. Do not mix.

Step 5 — Add Water and Butter

Drizzle the hot water evenly over the entire surface.
Pour the remaining ¾ cup melted butter over the dry cake mix.

This helps create a buttery, crisp topping.

Step 6 — Add Extra Pecans

Scatter the remaining 1 cup pecans across the top for crunch and caramelization.

Step 7 — Bake

Bake for 45–55 minutes, or until the top is golden brown and the edges are bubbling.

Step 8 — Serve

Allow the cake to cool for at least 15 minutes before serving.
Add caramel drizzle for extra decadence.
