How to Make Blueberry Coffee Cake
For the Cake:
Mix the first 6 ingredients together in a medium bowl, making sure its well combined. Cover the cake batter with blueberries before baking.
Combine the cinnamon and sugar in a separate small bowl and set aside. Reserve ¾ of the cinnamon sugar mixture for the middle of cake and the remainder to mix into the streusel.
Spread half of the batter into the prepared pan. Sprinkle 3/4 of the cinnamon sugar mixture over the cake. Place remaining batter over the cinnamon sugar mixture. You can do this in dollops. The batter will be very thick.
Mix remaining cinnamon sugar into the streusel and cover the cake with the streusel.
Bake the cake for 50 to 60 minutes, or until a toothpick comes out clean. Start checking the cake at 45 minutes because ovens vary. If the streusel starts to brown, cover with a piece of foil to prevent burning.
