Ingredients
Method
Preparation
- Preheat your oven to 350°F (175°C). Grease a 9-inch round springform pan and line the bottom with parchment paper.
- In a medium bowl, whisk together the gluten-free all-purpose flour, baking powder, baking soda, and salt. Set aside.
Mixing
- In a large bowl, beat the softened butter and granulated sugar together for about 3 to 4 minutes until light and fluffy.
- Mix in the eggs one at a time, then stir in the vanilla extract.
- Add half of your dry mixture to the butter mixture and mix gently, then add the sour cream and blend until smooth. Fold in the remaining dry ingredients until just combined.
Filling and Topping
- In a small bowl, stir together the brown sugar, ground cinnamon, and gluten-free flour for the filling.
- Spread half of the prepared batter in the bottom of the springform pan, sprinkle the cinnamon filling over this layer, and gently spread the remaining batter on top.
- In a separate bowl, combine the crumb topping ingredients until crumbly and sprinkle over the batter.
Baking
- Place the cake in the oven and bake for 45-55 minutes until a toothpick inserted into the center comes out clean.
- Allow the coffee cake to cool in the pan for at least 20 minutes before removing and slicing.
