Ingredients

Wet Ingredients

  • 1 stick (1/2 cup) melted salted butter, cooled
  • 3/4 cup granulated sugar
  • 2 large eggs
  • 1/2 cup whole milk
  • 1 tsp vanilla extract

Dry Ingredients

  • 1.5 cups all purpose flour
  • 1 tsp baking powder
  • 1/2 tsp cinnamon
  • 1.5 cups frozen blueberries

Coffee Cake Topping

  • 1/2 cup melted salted butter (1 stick)
  • 2/3 cup all purpose flour
  • 1/3 cup light brown sugar
  • 1/3 cup granulated sugar
  • 1/2 tsp cinnamon

Easy Vanilla Glaze

  • 1/3 cup powdered sugar
  • 1-2 tbsp milk (more if you want the glaze thinner, less if you want it thicker)
  • splash of vanilla extract

Instructions

  1. Preheat oven to 350.

  2. In a large bowl, melt one stick of butter. Let it cool for a few minutes. Next, add in the granulated sugar and using a handheld mixer, mix for about 30 seconds. Add in the eggs one at a time until fully combined. Then, add in milk and vanilla extract and mix to combine.

  3. To the bowl with the wet ingredients, add the dry ingredients which includes the all purpose flour, baking powder and cinnamon. Stir to combine with a wooden spoon or rubber spatula, making sure it’s fully mixed together. 

  4. Lastly, gently fold in the frozen blueberries until combined.

  5. Grease a 9x9 baking pan with cooking spray or butter.

  6. Add the batter to the greased pan.

  7. In a small bowl, melt another stick of butter. To this, add in all purpose flour, brown sugar, granulated sugar and cinnamon. Mix together. This will look a little wet but that's okay!

  8. Spread the brown sugar mixture over top of the batter evenly.

  9. Bake for 50-55 minutes or until a toothpick comes clean. Let cool in the pan for 10 minutes or so and then invert it onto a cooling rack and let it cool completely!

  10. Once it's cooled, whisk together the powdered sugar, milk and vanilla extract to make the glaze. Make it as thick or thin as you'd like it! Generously drizzle it over top of the coffee cake.

  11. Slice it up and enjoy every bite!
