Autumn Pumpkin Spice Crumble Cake

### Instructions

#### 1. Preheat the Oven and Prepare the Pan:
Start by preheating your oven to 350°F (175°C). Grease and flour a 9-inch round or square cake pan, or line it with parchment paper for easy removal.

#### 2. Make the Pumpkin Spice Cake:
In a medium bowl, whisk together the dry ingredients: flour, baking powder, baking soda, cinnamon, nutmeg, ginger, cloves, and salt. In a separate large bowl, combine the pumpkin puree, granulated sugar, brown sugar, eggs, vegetable oil, vanilla extract, and sour cream (or Greek yogurt). Stir until everything is well incorporated.

Gradually add the dry ingredients to the wet ingredients, mixing just until combined. Be careful not to overmix, as this can make the cake dense. The batter should be thick and smooth.

#### 3. Prepare the Crumble Topping:
In a small bowl, combine the flour, rolled oats, brown sugar, cinnamon, and a pinch of salt. Add the cold cubed butter and use your fingers or a pastry cutter to rub the butter into the dry ingredients until the mixture resembles coarse crumbs. This will create that delightful crumbly texture on top of your cake.

#### 4. Assemble the Cake:
Pour the pumpkin cake batter into the prepared cake pan, smoothing the top with a spatula. Evenly sprinkle the crumble topping over the cake batter, making sure the top is well covered.

#### 5. Bake:
Place the cake in the oven and bake for 40 to 45 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs. The cake should be golden brown, and the crumble topping will be slightly crisp.

#### 6. Cool and Serve:
Allow the cake to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely. Once cooled, slice and serve as a delicious dessert or a sweet treat for breakfast with a cup of coffee or tea.

### Tips for the Perfect Autumn Pumpkin Spice Crumble Cake:
– **Pumpkin Puree:** Make sure to use pure pumpkin puree, not pumpkin pie filling, which contains added sugar and spices.
– **Crumble Texture:** If the crumble topping isn’t coming together, you can add a little more butter to help bind the ingredients together.
– **Make It Ahead:** This cake can be made ahead and stored in an airtight container for up to 3 days, or frozen for up to 3 months.
– **Add-ins:** For extra texture and flavor, consider adding chopped walnuts, pecans, or even chocolate chips to the batter.
