Soft, fluffy yellow cake with a brown sugar nut streusel topping. This easy, from-scratch blueberry coffee cake is perfect for breakfast or brunch. Use any fruit you'd like!
In a medium-size bowl, beat together the egg, sugar, oil and vanilla until fluffy.
In a small bowl, combine the flour, baking powder and salt. Whisk until well combined.
Add the dry ingredients alternately with the milk. Mix just until combined.
Fold in the blueberries.
Spray an 8" or 9" square pan with cooking spray.
Pour the batter into the prepared pan.
For the topping, combine the brown sugar, flour, cinnamon, butter and nuts. Mix well. Sprinkle the topping over the cake batter.
Bake for 25-35 minutes. If the pan is a 9" pan, it will take closer to 25 minutes. If it is an 8" pan, it will be done in closer to 35 minutes.
Serve warm.
