This pumpkin coffee cake is for anyone who believes there can never be too much crumb topping. Unlike a traditional coffee cake with a thin layer of streusel, this one is made with nearly equal parts moist pumpkin cake and buttery crumb topping. So every bite is packed with plenty of that cinnamon-sugar goodness.
WHAT YOU NEED Crumble all-purpose flour or 1-to-1 gluten-free baking flour cornstarch granulated sugar light brown sugar ground cinnamon kosher salt unsalted butter Pumpkin Coffee Cake vegetable oil granulated sugar large egg + egg yolk vanilla extract 100% pure pumpkin pumpkin pie spice ground cinnamon baking soda baking powder kosher salt coarse ground black pepper all-purpose flour or 1-to-1 gluten-free baking flour powdered sugar
1. Preheat the oven to 350F and grease an 8×8 baking dish. Line the bottom and two sides with a sheet of parchment paper. 2. In a medium bowl, use your hands to mix together all of the crumble ingredients, minus the butter. Once combined, pour in the butter and use a spatula to mix everything together until evenly hydrated. Set aside.
Crumble
1. In a large bowl, whisk together the oil and sugar until evenly combined, then whisk in the egg, egg yolk, vanilla, and pumpkin until smooth. 2. Add the pumpkin pie spice, cinnamon, baking soda, baking powder, salt, and pepper and whisk to evenly distribute. Then add in the flour and whisk until fully incorporated, careful not to over mix. 3. Spread the batter evenly in the pan and top with a layer of the crumble topping, breaking it up with your hands as you sprinkle it on top.

4. Bake for 30 to 35 minutes or until the cake is evenly puffed and the center does not move when the pan is nudged. Allow to cool in the pan for about 20 minutes, then lift it out onto a cooling rack and cool completely either at room temperature or in the refrigerator. 5. Once cooled, top with a dusting of powdered sugar and it’s ready to slice and enjoy! Store in a container at room temperature for a couple days, or for about a week in the refrigerator.
