Ingredients
- 1 cup pumpkin puree
The star ingredient, pumpkin puree, adds moisture and a rich flavor while providing essential nutrients like vitamin A. Opt for canned pumpkin or homemade puree for convenience. - 1 cup all-purpose flour
All-purpose flour acts as the base for the cake structure, allowing it to rise and hold its shape while creating a tender crumb. - 1/2 cup granulated sugar
Granulated sugar sweetens the cake, balancing the natural earthiness of the pumpkin. It also aids in creating a desirable texture. - 1/2 cup packed brown sugar
Brown sugar adds a deeper, richer sweetness, along with a hint of molasses flavor, enhancing the autumnal taste profile. - 1/4 cup unsalted butter, melted
Butter enriches the cake with flavor and moisture. Its fat content helps create a tender crumb by coating the flour proteins. - 2 large eggs
Eggs act as binding agents, giving structure to the cake. They also add moisture and contribute to the overall rich flavor. - 1 tsp vanilla extract
Vanilla extract introduces a warm, aromatic note that complements the spices and pumpkin beautifully. - 1 tsp baking powder
Baking powder is the leavening agent that helps the cake rise, giving it a light and airy texture. - 1 tsp baking soda
Baking soda works in conjunction with the acidic ingredients to produce carbon dioxide bubbles, contributing to the cake’s lightness. - 1 tsp pumpkin pie spice
A blend of cinnamon, nutmeg, and ginger, pumpkin pie spice is critical for imparting that quintessential autumn flavor that resonates with the season. - 1/4 tsp salt
Salt amplifies the flavors in the cake, balancing the sweetness and enhancing the overall taste profile. - 1 cup old-fashioned oats
Oats form the base of the crumble topping, adding texture and nuttiness, and complementing the softness of the cake. - 1/2 cup chopped pecans
Pecans add a delightful crunch and richness to the crumble. Their buttery flavor enhances the nutty notes of the oats. - 1/4 cup maple syrup
Maple syrup sweetens the crumble with a unique flavor, echoing the warm notes of autumn and providing moisture.
Directions & Preparation
Step 1: Preheat your oven to 350°F (175°C). Grease and line an 8-inch square baking pan with parchment paper.
Preheating the oven ensures that your cake bakes evenly from the moment it goes in. Lining your baking pan prevents sticking, making it easier to remove the cake once baked.
Step 2: In a large mixing bowl, combine pumpkin puree, granulated sugar, brown sugar, melted butter, eggs, and vanilla extract. Mix until smooth and well incorporated.
This step is crucial as it creates a cohesive batter. The sugars will dissolve, and incorporating the eggs fully will ensure a uniform texture throughout the cake.
Step 3: In a separate bowl, whisk together the all-purpose flour, baking powder, baking soda, pumpkin pie spice, and salt.
Separately whisking the dry ingredients ensures even distribution of the leavening agents and spices throughout the batter. This prevents any clumping and helps in achieving a consistent rise.
Step 4: Gradually add the dry mixture to the wet ingredients, folding gently until just combined. Be careful not to overmix, as this could lead to a dense cake.
Overmixing can develop the gluten in the flour unnecessarily, resulting in a tougher cake. Gently folding helps maintain a tender crumb, ensuring a soft texture.
Step 5: Scrape the batter into the prepared pan, smoothing the top evenly with a spatula.
Smoothing the top creates an even surface for baking and helps the cake to rise uniformly, resulting in a beautiful final product.
Step 6: In a separate bowl, prepare the crumble by combining oats, chopped pecans, melted butter, maple syrup, and a pinch of salt. Mix until crumbly.
Creating a crumble texture is vital for ensuring it distributes evenly on top of the cake. The mixture should resemble small crumbs that can easily be sprinkled without clumping.
Step 7: Sprinkle the crumble mixture evenly over the pumpkin batter in the pan.
Even distribution of the crumble topping ensures each bite is packed with flavor and texture, balancing the soft cake beneath.
Step 8: Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
Proper baking time is crucial for achieving the right consistency. Overbaking can lead to a dry cake, while underbaking might leave it gooey in the middle.
Step 9: Allow the cake to cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
Cooling in the pan helps set the structure of the cake. Transferring to a wire rack allows for even heat distribution and prevents sogginess from steam.
Step 10: Once cool, cut into squares and serve, optionally with whipped cream or a dusting of powdered sugar.
Presentation plays a key role in enjoyment. Serving with whipped cream enhances richness and adds a luxurious feel to the dish, inviting you to savor each bite.

FAQs
What should I do if my batter is too thick?
If your batter seems too thick, you can add a tablespoon or two of milk to loosen it up. This will help achieve a better texture as it bakes.
How can I ensure my cake is flavorful enough?
To enhance the flavor, make sure you use freshly ground spices instead of pre-ground ones, as they have a more vibrant taste. Adjusting the amount of pumpkin spice slightly can also boost the overall flavor.
What if my crumble topping gets too brown during baking?
If your crumble is browning too quickly, cover the cake loosely with aluminum foil during the last few minutes of baking. This will prevent further browning while allowing the cake to finish cooking.
Can I scale this recipe to fit a larger pan?
Yes, for a larger pan, you can double the ingredients and bake in a 9×13-inch pan. Adjust the baking time as needed, potentially increasing it by 5-10 minutes.
What if my cake is too moist after baking?
If your cake is too moist, it may need more time in the oven. Check for doneness by inserting a toothpick in the center; it should come out clean.
What can I do if my crumble topping is too dry?
If your crumble seems dry and crumbly without clumping, add an additional tablespoon of melted butter or maple syrup to help bind it together.
