Ingredients You’ll Need

Gathering your ingredients for this Pumpkin Oatmeal Dump Cake is a breeze, and each one plays a crucial role in building that perfect balance between creamy, crunchy, and spice-kissed warmth.

• Pumpkin puree: The star ingredient providing smooth texture and that unmistakable fall flavor.
• Evaporated milk: Adds richness and helps create a custard-like base.
• Eggs: Essential for binding the pumpkin mixture and giving it structure.
• Granulated sugar: Sweetens the pumpkin filling gently without overpowering.
• Brown sugar: Adds a deep molasses note that complements the spices beautifully.
• Cinnamon: A classic warming spice that enhances the pumpkin’s flavor.
• Nutmeg: Offers a nutty, slightly sweet spice that lifts the whole dessert.
• Ginger: Gives just a hint of zesty heat to keep things interesting.
• Cloves: Provides a subtle depth and aromatic intensity.
• Yellow cake mix: Acts as the dry, crumbly layer that crisps up in the oven.
• Rolled oats: Adds hearty texture and wholesome crunch to the topping.
• Chopped pecans (optional): For extra nutty crunch and a lovely contrast to the soft filling.
• Melted butter: Drizzled on top to glue everything together and create a golden crust.

How to Make Pumpkin Oatmeal Dump Cake

Step 1: Preheat and Prepare Your Dish

Start by preheating your oven to 350°F (175°C). Grease a 9×13-inch baking dish well—this ensures your Pumpkin Oatmeal Dump Cake lifts out easily and bakes evenly with a beautifully caramelized edge.

Step 2: Whisk the Pumpkin Mixture

In a large bowl, combine the pumpkin puree, evaporated milk, eggs, granulated sugar, brown sugar, and all your spices (cinnamon, nutmeg, ginger, and cloves). Whisk everything until it’s perfectly smooth and all those flavors start mingling. This creamy mixture forms the juicy, flavorful base of your dump cake.

Step 3: Pour and Layer

Pour the pumpkin mixture evenly into your greased baking dish. Then, gently sprinkle the dry yellow cake mix right on top—resist the urge to stir. It might seem like a simple step, but this layer forms the cakey topping that crisps up beautifully as it bakes.

Step 4: Top with Oats and Pecans

Scatter the rolled oats over the cake mix layer, and if you’re feeling nutty, add the chopped pecans on top of that. These layers bring texture and a wonderful nutty aroma to the Pumpkin Oatmeal Dump Cake.

Step 5: Drizzle with Melted Butter

Finally, drizzle the melted butter evenly over the oats and pecans. This step is what makes the topping golden, crunchy, and irresistible with every bite.

Step 6: Bake to Perfection

Place the baking dish in your oven and bake for 50 to 60 minutes. You’ll know it’s done when the top turns a gorgeous golden brown and a toothpick inserted into the center comes out clean. Let it cool slightly—but don’t wait too long to dig in!

How to Serve Pumpkin Oatmeal Dump Cake

Garnishes

Serve your Pumpkin Oatmeal Dump Cake with a generous dollop of whipped cream or a scoop of vanilla ice cream for a cool, creamy contrast. A sprinkle of cinnamon or a few toasted pecans on top can add extra flair and texture, making each bite even more delightful.

Side Dishes

This dessert pairs wonderfully with a hot cup of spiced tea or freshly brewed coffee, perfect for cozy afternoons or after a hearty meal. For a festive touch, serve alongside warm mulled cider or pumpkin spice latte to deepen all those seasonal flavors.

Creative Ways to Present

If you want to make your Pumpkin Oatmeal Dump Cake truly special, try serving it in individual ramekins or mason jars. Layer it with whipped cream and a drizzle of caramel for a stunning dessert parfait. You can also add a sprinkle of crushed gingersnaps on top for an extra crunch and spice.

Make Ahead and Storage

Storing Leftovers

Store any leftover Pumpkin Oatmeal Dump Cake in an airtight container in the refrigerator. It will keep beautifully for up to 4 days, and the flavors often deepen and mellow with time, making each serving even more comforting.

Freezing

You can freeze the cake for up to 2 months by wrapping it tightly with plastic wrap and aluminum foil. Thaw it overnight in the refrigerator and reheat gently to bring back that freshly baked warmth and texture.

Reheating

To reheat, warm individual portions in the microwave for about 30 seconds or pop the whole thing in a 325°F oven covered loosely with foil until heated through. Adding a fresh dollop of whipped cream or scoop of ice cream after reheating is always a winning idea.

FAQs

Can I use canned pumpkin pie filling instead of pumpkin puree?

It’s best to stick with plain pumpkin puree because pumpkin pie filling contains added sugar and spices that might throw off the balance of flavors and texture in your Pumpkin Oatmeal Dump Cake.

What if I don’t have rolled oats? Can I substitute something else?

If you don’t have rolled oats, quick oats can work in a pinch, but avoid instant oats as they might turn mushy. You could also try finely chopped nuts or even granola for a crunchy topping.

Is it possible to make this recipe gluten-free?

Absolutely! Use a gluten-free yellow cake mix and make sure your oats are certified gluten-free. This way, everyone can enjoy this delicious Pumpkin Oatmeal Dump Cake without worry.

Can I make this dessert vegan?

With some substitutions like using a plant-based evaporated milk alternative, flax eggs or another egg replacer, and vegan butter, you can create a lovely vegan version of this dessert, though the texture might be slightly different.

How do I know when my Pumpkin Oatmeal Dump Cake is done baking?

Look for a golden-brown top and test by inserting a toothpick into the center. If it comes out clean or with just a few moist crumbs, your cake is perfectly baked and ready to enjoy.
