Ingredients
Method
Preparation
- Preheat your oven to 350°F (175°C) and grease a 9-inch round cake pan.
- In a mixing bowl, cream together the softened butter and granulated sugar until light and fluffy, about 3-4 minutes.
- Add the eggs, one at a time, mixing well after each addition. Stir in the vanilla extract.
- In another bowl, combine the flour, baking powder, and salt. Gradually add this dry mixture to the wet ingredients, alternating with the milk. Mix until just combined; be careful not to overmix.
- In a separate bowl, toss the mixed berries with brown sugar and cornstarch. Set aside to marinate.
Assembly
- Pour half of the batter into the prepared cake pan, then carefully layer the berry mixture on top, followed by the remaining batter.
- For the topping, mix together the rolled oats, brown sugar, flour, melted butter, and cinnamon until crumbly. Sprinkle evenly over the cake.
Baking
- Bake for 40-45 minutes or until a toothpick inserted in the center comes out clean and the top is golden brown.
- Allow the cake to cool for at least 15 minutes in the pan before transferring it to a wire rack to cool completely.
Notes
To make it lighter, consider substituting half of the flour with whole wheat flour and using a sugar alternative like coconut sugar. This coffee cake can be stored in an airtight container at room temperature for up to 3 days, or in the fridge for a week. It also freezes well; wrap individual slices tightly and store them.
