About the Ingredients
Pumpkin Puree
The base of the recipe, providing natural sweetness, moisture, and that classic fall flavor.
Evaporated Milk
Adds richness and creaminess, making the pumpkin layer smooth and custard-like.
Eggs
Help bind the filling and give it structure.
Sugar
A mix of granulated and brown sugar provides sweetness with a hint of molasses depth from the brown sugar.
Pumpkin Pie Spices
Warm spices like cinnamon, nutmeg, ginger, and cloves enhance the pumpkin flavor.
Yellow Cake Mix
Acts as a topping, creating a crumbly, golden crust.
Rolled Oats
Add texture and a rustic flavor that pairs perfectly with pumpkin.
Pecans
Provide crunch and a nutty flavor that elevates the dessert.
Melted Butter
Helps brown the topping while giving it a rich, buttery taste.
Tips & Tricks
Choose the Right Pumpkin
Use pumpkin puree, not pumpkin pie filling. The canned pie filling already contains sugar and spices, which can make the dessert overly sweet.
Even Butter Distribution
Drizzle the melted butter carefully to ensure the oats and cake mix bake evenly without dry patches.
Check for Doneness
Test doneness with a toothpick. Insert into the center – if it comes out mostly clean, the cake is ready.
Pro Tips
- Let it rest before slicing to allow the layers to firm up for cleaner cuts.
- For extra flavor, consider toasting the pecans before adding them to the cake.
- Serve with a dollop of whipped cream or a scoop of vanilla ice cream for a delightful contrast.
Step-by-Step Instructions
Prepare the Oven and Dish
Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking dish to prevent sticking.
Mix the Pumpkin Filling
In a large bowl, whisk together the pumpkin puree, evaporated milk, eggs, granulated sugar, brown sugar, cinnamon, nutmeg, ginger, and cloves until the mixture is smooth and well combined.
Assemble the Cake
Pour the pumpkin mixture evenly into the prepared dish. Then, sprinkle the dry yellow cake mix evenly over the pumpkin filling, followed by the rolled oats and pecans.
Add the Butter
Drizzle the melted butter evenly over the topping, ensuring that it covers the entire surface to promote even baking.
Bake and Serve
Bake the cake for 50–60 minutes, until the top is golden brown and set. Allow to cool slightly before serving. Enjoy warm or at room temperature.
Delicious Variations
Spice Cake Mix
Use a spice cake mix instead of yellow cake mix to enhance the fall flavors even more.
No Nuts
Omit the pecans for a nut-free version that still offers delightful texture from the oats.
Extra Crunch
Add a handful of chopped walnuts or almonds for an additional layer of crunch and flavor.
