⭐ Instructions

1. Make the crumb topping

In a medium bowl, mix flour, brown sugar, granulated sugar, pumpkin pie spice, and salt.
Stir in melted butter and vanilla until crumbs form.
Place in fridge while you make the cake (helps firm it up).

2. Preheat oven

Heat oven to 350°F (175°C).
Grease an 8×8 or 9×9 baking pan (or line with parchment).

3. Make the pumpkin cake

1. In a bowl, whisk flour, baking powder, baking soda, salt, and pumpkin pie spice.
2. In a separate bowl, beat butter with brown sugar + granulated sugar until creamy.
3. Add eggs one at a time.
4. Mix in pumpkin purée, vanilla, and sour cream.
5. Fold in dry ingredients until just combined (don’t overmix).

4. Assemble

Spread cake batter into the pan.
Sprinkle crumb topping evenly over the batter.

5. Bake

Bake 35–45 minutes, depending on pan size.
Done when the center springs back lightly or a toothpick comes out clean.

6. Glaze (optional)

Whisk glaze ingredients and drizzle over cooled cake.
