 Ingredients (Serves 10–12)

For the Pumpkin Base:

• 1 can (15 oz) pumpkin puree (not pumpkin pie filling)

• 1 can (12 oz) evaporated milk

• 3 large eggs

• ¾ cup brown sugar, packed

• ½ cup granulated sugar

• 2 teaspoons pumpkin pie spice

• 1 teaspoon ground cinnamon

• ½ teaspoon salt

• 1 teaspoon pure vanilla extract

For the Topping:

• 1 box (about 15.25 oz) yellow cake mix or spice cake mix

• ¾ cup old-fashioned rolled oats

• 1 cup unsalted butter, melted

• ½ cup chopped pecans or walnuts (optional for crunch)

 Instructions

1. Preheat Oven

Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or non-stick spray.

2. Mix the Pumpkin Layer

In a large bowl, whisk together:

• Pumpkin puree

• Evaporated milk

• Eggs

• Brown sugar

• Granulated sugar

• Pumpkin pie spice

• Cinnamon

• Salt

• Vanilla extract

Mix until smooth and fully combined.

Tip: Taste the mixture (before adding eggs, if you like) to adjust sweetness or spice.

3. Pour Into Pan

Pour the pumpkin mixture evenly into the prepared baking dish. Spread it out into a smooth layer.

4. Add the Dump Cake Topping

1. Sprinkle the dry cake mix evenly over the pumpkin layer. Do not mix!

2. Add a layer of rolled oats on top of the cake mix.

3. Drizzle the melted butter evenly over the entire surface. Make sure most of the cake mix is moistened.

4. Sprinkle with chopped nuts, if using.

Butter Tip: Pour butter slowly and evenly to avoid dry patches. Alternatively, dot the top with cold butter slices if preferred.

5. Bake

Bake in the preheated oven for 45–50 minutes, or until the top is golden brown and the center is mostly set (a slight jiggle is okay).

⏱️ Check at 40 minutes. If the top is browning too quickly, loosely tent with foil.

6. Cool & Serve

• Let the cake cool for at least 15–20 minutes to allow it to set.

• Serve warm, at room temperature, or chilled.

• Optional: Top with a dollop of whipped cream, vanilla ice cream, or a drizzle of maple syrup.
