Ingredients
Method
Preheat and Prepare
- Preheat your oven to 325°F (160°C). Line an 8x8 inch baking dish with aluminum foil, leaving extra hanging over the edges for easy removal. Spray the foil lightly with nonstick cooking spray.
Make the Topping
- In a medium bowl, combine the melted butter, both granulated and brown sugar, cinnamon, and salt. Stir in the cake flour until crumbly. Set aside.
Make the Cake Batter
- In a stand mixer, combine the 1 1/4 cups cake flour, sugar, pumpkin pie spice, salt, and baking soda. Mix on low until combined.
- Add the room-temperature butter pieces, mixing until the mixture resembles coarse crumbs.
- In a separate bowl, whisk together the pumpkin purée, buttermilk, egg, egg yolk, and vanilla extract. Add this wet mixture to the dry ingredients and beat until the batter is fluffy and well combined.
Assemble
- Pour the batter into the prepared baking dish and spread it evenly. Sprinkle the crumb topping generously over the batter.
Baking
- Bake for 38-40 minutes or until golden brown. A toothpick inserted should come out with a few moist crumbs attached.
Cooling
- Allow the cake to cool slightly before using the foil edges to lift it out of the pan. Let it cool completely on a wire rack.
Serving
- Dust the top with confectioners' sugar just before serving to add a lovely finishing touch.
Notes
For an extra moist cake, avoid overbaking, and keep an eye on the time! Allowing the butter to come to room temperature helps create a fluffier batter. Store at room temperature for up to 2 days or refrigerate for up to 1 week.
