Instructions
Getting Ready
Preheat the oven to 350 F, and position a rack in the center of the oven.
Spray a 9-inch baking dish with non-stick baking spray, or prep the pan with butter and flour.(An 8-inch pan is too small for the amount of batter in this recipe, but you can multiply the recipe by 1 1/2 - 2x and bake it in a 9x13 pan.)
Cake
To make the cake batter, whisk all of the liquid ingredients (pumpkin, melted butter, sugars, milk, eggs and vanilla) in a large bowl. Separately, sift together the dry ingredients (flour, corn starch, baking soda, salt and spices). Add the dry ingredients to the liquid and whisk just until moistened, but a few streaks of flour remain.
Spread the batter evenly into the prepared baking dish.
Topping
In a bowl, combine all of the crumb topping ingredients until moistened and crumbly.
Sprinkle the topping over the batter.
Bake
Bake for about 35-40 minutes, until a toothpick or cake tester inserted in the center comes out clean, or with moist crumbs clinging to it.
Set the pan on a cooling rack, and cool the cake for about 30-45 minutes, then slice and serve warm.
Notes
Store leftover coffee cake in an airtight container at room temperature for up to 3-4 days, or in the freezer for up to 3-6 months.For a just-baked texture, warm up leftover pieces in the microwave at 50% power for 20-30 seconds.
