Method
Make the cake
- Heat the oven to 350°F.
- Coat an 8-inch square baking pan with cooking spray.
- Whisk the flour, baking powder, baking soda, cream of tartar, cinnamon, and salt in a medium bowl.
- Beat the softened butter and 3/4 cup granulated sugar in a large bowl until light and fluffy, about 2 minutes.
- Beat in the egg and vanilla.
- Mix in the pumpkin puree until combined.
- Add the flour mixture and mix on low just until no dry streaks remain.
Make the topping and bake
- Stir the 2 tablespoons granulated sugar and 1 teaspoon cinnamon together in a small bowl.
- Sprinkle the cinnamon-sugar evenly over the batter.
- Bake for 32 to 38 minutes, until the center is set and a toothpick inserted in the center comes out with a few moist crumbs.
- Cool in the pan for at least 20 minutes before cutting and serving.
Notes
For a tender crumb, mix the flour in just until no dry streaks remain. Store covered in the refrigerator for up to 4 days; freeze slices for up to 2 months. A dairy-free butter substitute can replace the unsalted butter.
