Step‑by‑Step Instructions for Pumpkin Spice Crumble Cake
Step 1: Prepare Oven and Pan
Begin by preheating your oven to 350°F (175°C) and greasing a 9-inch square baking pan with cooking spray or butter. This will keep your Pumpkin Spice Crumble Cake from sticking. Set the pan aside while you gather and measure out your ingredients, ensuring everything is at hand for a smooth baking experience.
Step 2: Mix Dry Ingredients
In a large mixing bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon of baking powder, ½ teaspoon of baking soda, 1 teaspoon of cinnamon, ½ teaspoon of nutmeg, ½ teaspoon of ginger, and a pinch of salt. The dry ingredients should be well combined to ensure the flavors of your Pumpkin Spice Crumble Cake are evenly distributed. This mix will create the delicious base of your cake.
Step 3: Combine Wet Ingredients
In a separate bowl, whisk together 1 cup of pumpkin puree, 2 large eggs (at room temperature), ½ cup of vegetable oil, ½ cup of brown sugar, and ½ cup of granulated sugar. Whisk until the mixture is smooth and well-blended, as this helps create a moist texture in your cake. This combination will provide the rich flavor that defines the Pumpkin Spice Crumble Cake.
Step 4: Combine Mixtures
Gently fold the wet ingredients into the bowl of dry ingredients, stirring until just combined—be careful not to overmix. You should see no flour streaks, and the batter should be thick and slightly lumpy. This step is crucial in maintaining a tender crumb in your Pumpkin Spice Crumble Cake, so mix it with love and patience.
Step 5: Prepare Crumble Topping
In a medium bowl, combine ½ cup of cold butter (cut into small pieces), 1 cup of all-purpose flour, and ½ cup of sugar. Using a pastry cutter or your fingers, mix until the texture resembles coarse crumbs. This crumble topping will add a delightful crunch on top of your cake, ensuring every bite is full of comforting textures.
Step 6: Bake
Pour the batter into your prepared baking pan, spreading it evenly. Sprinkle the crumble topping generously over the batter. Place the pan in the preheated oven and bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. You’ll know your Pumpkin Spice Crumble Cake is ready when it springs back slightly when touched.
Step 7: Cool and Serve
Once baked, remove the cake from the oven and let it cool in the pan for about 10 minutes before transferring it to a wire rack. Allow it to cool slightly before slicing into squares. Serve warm for the best experience, and savor the cozy flavors of autumn in every delicious bite!

Expert Tips for Pumpkin Spice Crumble Cake
-
Room Temperature Eggs: Ensure your eggs are at room temperature for better incorporation, which keeps the cake light and fluffy when baked.
-
Fresh Ingredients: Check the freshness of your baking powder and baking soda; expired leavening agents can lead to a dense Pumpkin Spice Crumble Cake.
-
Avoid Overmixing: Gently fold wet and dry ingredients together without overmixing to maintain a tender texture; overworking the batter can create a tough cake.
-
Proper Crumble Texture: Use cold butter in the crumble topping to achieve that delightful crunch; warm butter will give a soggy texture instead.
-
Monitor Baking Time: Keep an eye on your cake and do the toothpick test early—start checking at 25 minutes to ensure it doesn’t overbake, maintaining moistness.
-
Pumpkin Purée Quality: Use real pumpkin purée rather than pumpkin pie filling, which often contains additional sugars and spices that can alter the flavor balance of your cake.

Autumn Pumpkin Spice Crumble Cake Recipe FAQs
What type of pumpkin puree should I use?
I highly recommend using real pumpkin puree instead of pumpkin pie filling. The latter often contains added sugars and spices that can throw off the flavor of your Pumpkin Spice Crumble Cake. You want pure pumpkin for that rich, warm essence that only true pumpkin can provide.
How should I store the Pumpkin Spice Crumble Cake?
Store your cake in an airtight container at room temperature for up to 2 days to maintain its wonderful flavors and texture. If you want to keep it longer, it can be refrigerated for up to a week, but be sure to wrap it well to prevent it from drying out.
Can I freeze the Pumpkin Spice Crumble Cake?
Absolutely! To freeze your cake, wrap individual slices tightly in plastic wrap, then place them in a freezer bag. This method helps preserve the moistness and flavor. Your baked goods can last for up to 3 months in the freezer. When you’re ready to enjoy, simply thaw in the refrigerator overnight and reheat slices in the microwave for about 10-15 seconds for the best results.
What should I do if my cake is too dense?
If your Pumpkin Spice Crumble Cake turns out dense, it might be due to overmixing the batter after combining the wet and dry ingredients. To achieve a lighter texture, mix gently until just combined—it’s perfectly fine if there are a few lumps! Additionally, ensure you’re using fresh baking powder and baking soda, as expired leavening agents can lead to a heavy cake.
Is there a gluten-free option for this recipe?
Yes! To make your Pumpkin Spice Crumble Cake gluten-free, simply substitute all-purpose flour with a gluten-free flour blend. Many great blends exist on the market that will work beautifully in this recipe, so everyone can enjoy this autumn delight!
Can I modify this recipe for dietary restrictions?
Very much so! You can easily adapt this Pumpkin Spice Crumble Cake for vegan diets by substituting eggs with flax eggs (1 tablespoon of flaxseed meal mixed with 2.5 tablespoons of water for each egg) and using a plant-based oil. This way, it’s not only delicious but also caters to various dietary needs!
