Ingredients
 

Cake

  • 1 cup canned pumpkin puree (not pumpkin pie filling)
  • ½ cup unsalted butter, melted
  • ½ cup dark brown sugar, lightly packed
  • ½ cup granulated sugar
  • ½ cup whole milk
  • 2 large eggs
  • 1 tsp vanilla extract
  • 2 cups all-purpose flour, fluffed, spooned and leveled
  • 1 tbsp corn starch
  • ¾ tsp baking soda
  • ¼ tsp coarse Kosher salt (if using table salt, use half the amount)
  • ¾ tsp ground cinnamon
  • ¾ tsp ground ginger
  • ¼ tsp ground nutmeg
  • ¼ tsp ground cloves
  • ¼ tsp ground allspice

Topping

  • 1 ¼ cups all-purpose flour, fluffed, spooned and leveled
  • ½ cup dark brown sugar, lightly packed
  • ¼ cup granulated sugar
  • ½ tsp coarse Kosher salt (if using table salt, use half the amount)
  • ¼ tsp ground nutmeg
  • 6 tbsp unsalted butter, melted

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.
