Step 1

Heat oven to 375°. Prepare a 9-inch springform pan by spraying with cooking spray. Set aside.

Step 2

Combine all streusel ingredients into a small bowl. Use your clean fingers, a fork, or a pastry blender to combine everything together until you have a thick crumb mixture. Set aside.

Step 3

In a large mixing bowl, combine the flour, granulated sugar, softened butter, milk, egg, baking powder, and salt. Stir together until everything is combined.

Step 4

Add the fresh blueberries and very gently stir into the coffee cake batter. Just gently stir in the blueberries until incorporated. Stirring too hard or too much will make the blueberries bleed color into the batter.

Step 5

Spread the coffee cake batter into the prepared springform pan. Sprinkle the streusel topping evenly over the top.

Step 6

Cook for 55-65 minutes. If the edges and top are getting too browned, loosely lay a piece of tin foil over top to prevent over browning.

Step 7

The cake will be puffed up and a toothpick inserted in the middle should come out with dry crumbs NOT wet batter.

Step 8

Allow the cake to cool for 20 minutes. Loosen the edges of the cake from the pan with a butter knife and then remove the sides of the Springform pan.

Step 9

Combine all glaze ingredients in a small bowl and mix together. Add more or less milk until desired consistency is reached. Drizzle the glaze over the coffee cake.

Step 10

You can serve this coffee cake warm OR let it cool to room temperature and serve. Store leftovers in a covered container at room temperature.
