Blueberry Crumb Cake
For the cake
For the streusel
  1. In the bowl of a stand mixer, mix together the flour, brown sugar, sugar, cinnamon, and salt until there are no large lumps, about 45 seconds. Add butter and mix well until streusel looks like wet sand, about 2 1/2 minutes. Transfer to a separate bowl and set aside.
For cake
  1. Preheat oven to 350 degrees. Grease round pan with coconut oil or non-stick spray and set aside.
  2. Whisk together the flour, baking powder, and salt and set aside.
  3. In the bowl of a stand mixer, beat the butter, sugar, and zest on medium speed until light and fluffy. Beat in eggs (one at a time) and vanilla. Eggs will not fully incorporate.
  4. Slowly stir in the flour mixture on low speed until just combined (batter will be very thick). Gently fold in blueberries with a spoon or spatula.
  5. Pour the batter into the prepared pan and spread evenly. Sprinkle the streusel topping over batter.
  6. Bake for 50-55 minutes or until cake is golden brown and toothpick comes out clean. Cool completely.
