Instructions

Prepare the Oven and Cake Pan

Preheat your oven to 350°F (175°C) and grease a 9x13 inch baking pan.

Make the Cake Batter

In a large bowl, mix pumpkin puree, sugar, brown sugar, and vegetable oil until smooth. Add eggs one at a time, mixing well after each addition.

In another bowl, combine flour, baking soda, baking powder, salt, and pumpkin pie spice. Gradually add the dry mixture to the wet ingredients, stirring until just combined.

Prepare the Crumble

In a separate bowl, mix flour, oats, brown sugar, cubed butter, and cinnamon until crumbly.

Combine and Bake

Pour the cake batter into the prepared pan and top with the crumble mixture. Bake in the preheated oven for 50 minutes or until a toothpick inserted comes out clean.

Allow to cool before serving.

Serving Suggestions

Serve this Ultimate Autumn Pumpkin Spice Crumble Cake warm from the oven or at room temperature. Pair it with a dollop of fresh whipped cream or a scoop of vanilla ice cream for an extra indulgent treat. For an elegant touch, drizzle caramel sauce or sprinkle chopped nuts on top to amplify the flavors and textures. This not only enhances the visual appeal but also elevates the taste, creating a dessert that feels both rustic and refined.

Consider slicing the cake into individual portions and presenting it on a beautiful serving platter at your next gathering. Garnishing with a sprinkle of cinnamon or a few extra crumbs from the topping adds a nice touch of flair. A side of spiced chai or apple cider complements the flavors wonderfully, creating a well-rounded experience that encapsulates the essence of fall.

Storage Tips

To keep your Ultimate Autumn Pumpkin Spice Crumble Cake fresh, store it in an airtight container at room temperature for up to three days. If you prefer longer storage, you can refrigerate the cake for up to a week. Ensure it’s wrapped properly to prevent it from drying out. Before serving again, a quick warm-up in the microwave for a few seconds can revive its just-baked flavor and aroma.

For ultimate freshness, consider freezing any leftover cake. Slice the cake and wrap individual pieces in plastic wrap before placing them in a freezer-safe container. This way, you can easily thaw and enjoy a slice whenever a craving strikes. Just be sure to let the cake come to room temperature before enjoying, or briefly warm it in the oven for a delightful experience.
