Ingredients

• 1 can pumpkin puree
• 1 can evaporated milk
• 4 large eggs
• 1/2 cup sugar
• 1/2 cup packed light brown sugar
• 2 teaspoons pure vanilla extract
• 1 tablespoon pumpkin pie spice
• 1 teaspoon salt
• 1 box yellow cake mix
• 1 cup chopped pecans
• 1 cup unsalted butter, melted

How to make Pumpkin Crunch Cake

Step 1: First things first, get your oven ready. Preheat it to 350°F. Generously butter a 9×13 inch baking pan to prevent the cake from sticking.

Step 2: In a large mixing bowl, create the creamy pumpkin base. Whisk together the pumpkin puree, evaporated milk, eggs, granulated sugar, brown sugar, vanilla extract, pumpkin pie spice, and salt. Keep whisking until the mixture is completely smooth and well-combined. There should be no lumps.

Step 3: Pour this luscious pumpkin mixture into your prepared baking pan. Use a spatula to spread it out into an even layer, making sure it reaches all the corners.

Step 4: Now for the “crunch” part! Open the box of yellow cake mix and sprinkle the dry mix evenly all over the top of the pumpkin layer. Use your hands to very gently press the cake mix down into the pumpkin batter. You’re not mixing it in, just helping it adhere.

Step 5: Sprinkle the chopped pecans evenly over the cake mix. Then, take your melted butter and drizzle it as evenly as you can over the entire surface. Try to cover as much of the dry cake mix as possible, as this is what creates the buttery, crunchy topping.

Step 6: Carefully place the pan in your preheated oven and bake for 40 minutes. At the 40-minute mark, check on the cake. If the pecan topping is getting too dark, loosely cover the pan with a piece of aluminum foil. Continue to bake for another 10-20 minutes. The cake is done when the center is set and a knife inserted into the middle comes out mostly clean.

Step 7: Remove the cake from the oven and place the pan on a wire rack to cool completely to room temperature. Once cooled, it’s very important to chill the cake in the refrigerator for at least a few hours. This allows the pumpkin layer to fully set for clean slicing.

How to serve Pumpkin Crunch Cake

This Pumpkin Crunch Cake is best served chilled, straight from the refrigerator. The cold temperature makes the pumpkin layer firm and fudgy, like the perfect pumpkin pie. For an extra touch of decadence, serve each slice with a generous dollop of fresh whipped cream or a scoop of vanilla bean ice cream. A final sprinkle of chopped pecans or a light dusting of cinnamon on top makes it look as amazing as it tastes!

How to store Pumpkin Crunch Cake

Because of its creamy, custard-like base, this cake must be stored in the refrigerator. Cover the baking pan tightly with plastic wrap or transfer slices to an airtight container. It will stay fresh and delicious for up to 5 days. You can also freeze this cake! To do so, cut it into individual portions, wrap each one tightly in plastic wrap and then foil, and freeze for up to 3 months. Let it thaw in the refrigerator overnight before serving.

Tips to make

• Even Butter Distribution is Key: For the perfect crunchy topping with no dry spots, make sure you drizzle the melted butter as evenly as possible over the cake mix and pecans. A slow, steady pour works best.
• Don’t Skip the Chilling Time: I know it’s tempting to dig in right away, but chilling the cake for a few hours is crucial. It allows the pumpkin custard layer to set properly, ensuring clean slices and the perfect texture.
• Watch for Browning: Ovens can vary. Keep an eye on the cake around the 40-minute mark. If the pecan topping is browning too quickly, loosely tent it with foil for the remaining bake time to prevent it from burning.
• Mix It Up: Feel free to swap the pecans for chopped walnuts or even a mix of the two. You could also experiment with a spice cake mix instead of yellow cake mix for an extra layer of fall flavor.

FAQs About Pumpkin Crunch Cake

Can I use a different cake mix?

Absolutely! While yellow cake mix is the classic choice, a spice cake mix works wonderfully and enhances the fall flavors even more. A butter pecan or even a white cake mix would also be delicious alternatives.

Why is my topping powdery in some spots?

This usually happens when the melted butter doesn’t fully saturate all of the dry cake mix. When drizzling the butter, be slow and methodical, ensuring you cover the entire surface as evenly as possible. The butter is what transforms the dry mix into a crunchy, cookie-like topping.

Can I make this ahead of time?

Yes, this is a fantastic make-ahead dessert! You can bake it a day or two before you plan to serve it. Just let it cool completely, then cover and store it in the refrigerator. The flavors actually meld together and become even better overnight.
