Ingredients
Method
Preparation
- Heat oven to 350°F (175°C). Grease a 9 inch square pan and line with parchment for easy lifting.
- Make crumble: Stir flour, brown sugar, cinnamon, and salt. Pour in melted butter and mix until clumpy. Chill while you make the batter.
- Make ripple: Mix brown sugar, cinnamon, and flour in a small bowl.
Batter Mixing
- In one bowl, whisk flour, baking powder, baking soda, salt, and spices. In another bowl, whisk pumpkin, eggs, brown sugar, oil, coffee, vanilla, and sour cream.
- Stir dry ingredients into wet just until combined. Do not overmix.
Assembly
- Spread half the batter in the pan. Sprinkle ripple mix evenly over it. Dollop and gently spread the remainder of the batter on top.
- Evenly sprinkle the crumble mixture over the top.
Baking
- Bake for 40 to 50 minutes. Start checking at 38. A toothpick should come out with a few moist crumbs, not wet batter.
- Cool at least 20 minutes before slicing to allow it to set.
Serving
- If the top is browning too fast, loosely cover with foil for the last 10 minutes of baking.
Notes
Cake is better the next day as flavors settle. Store covered for up to 5 days or freeze slices for up to 2 months.
