How to make a simple pumpkin spice dump cake
First, preheat your oven to 350º F.
Grease a 9x13 baking dish. I use a classic glass casserole dish.
In a large mixing bowl, whisk together the pumpkin puree, evaporated milk, sugar, eggs, vanilla extract, and pumpkin pie spice until well combined.
Pour the pumpkin mixture into your prepared baking dish.
Sprinkle the dry cake mix evenly over the pumpkin mixture. DO NOT STIR!
Drizzle the melted butter over the top of the cake. Get it spread out as evenly as possible. If you need more coverage, you can melt and add more butter.
If desired, sprinkle nuts over the top.
Bake for about 40-50 minutes, or until the top is golden brown and a toothpick inserted in the middle comes out clean. Baking times will depend on your dish (metal or glass) and your oven.
Allow the cake to cool slightly before serving.
This easy pump cake is delicious on its own or served with whipped cream or vanilla ice cream.
Whipped cream is something I never buy pre made because it is so incredibly easy to make. Also, homemade whipped cream doesn’t deflate dramatically! Learn how to make your own whipped cream.
