Ingredients

  • Fresh Blueberries: Juicy, sweet-tart berries folded into the batter give you juicy pops of sweetness in every single bite. 
  • All-Purpose Flour: The backbone of the batter that provides structure and a delicate crumb. You’ll also need it in the streusel topping. 
  • Baking Powder and Baking Soda: These leavening agents work together to create a perfectly risen cake with a light, fluffy texture.
  • Granulated and Brown Sugar: A dynamic duo – white sugar lends a pure sweetness while brown sugar adds caramel notes and moisture. The brown sugar only goes in the topping.
  • Ground Cinnamon: Warm, sweet spice that enhances the flavor of the blueberries and adds depth to the streusel topping.
  • Unsalted Butter: Provides richness and moisture to the cake and the topping. 
  • Salt and Vanilla: Balance the sweetness and enhance all the other ingredients.
  • Large Eggs: Act as a binder, provide moisture, and help create a fluffy crumb.
  • Sour Cream: The secret weapon for an ultra-moist, tender crumb with a slightly tangy finish.
  • Powdered Sugar and Milk: Combine to create a sweet, smooth glaze that’s drizzled on top for a picture-perfect finish.

How to Make Blueberry Coffee Cake

There’s nothing quite like the aroma of a freshly baked blueberry coffee cake wafting through the kitchen.

And when it’s this easy to make, I’m sure it’ll go into your regular rotation!

1. PREP: Preheat the oven to 350°F (175°C). Grease and line a 9×9-inch baking pan with parchment paper. Set aside.

2. COMBINE: In a medium bowl, mix the flour, sugar, and cinnamon for the streusel. Cut in the cold butter until the mixture resembles coarse crumbs. Refrigerate.

3. WHISK: In a medium bowl, whisk the dry ingredients for the cake and set aside. 

4. BEAT: In a large bowl, beat the butter and sugar until light and fluffy. Then mix in the eggs (one at a time), vanilla, and sour cream. 

5. MIX: Gradually mix in the dry ingredients, stopping halfway. Add the blueberries and finish mixing until just combined.

6. BAKE: Pour the batter into the pan, sprinkle the streusel evenly on top, and bake for 55-60 minutes. Cool on a wire rack for at least 20 minutes.

7. GLAZE: In a small bowl, whisk the glaze ingredients until smooth and drizzle over the warm coffee cake. Serve warm or at room temperature. Enjoy!

Tips For the Best Blueberry Coffee Cake

This is the kind of cake that’s perfect for a lazy weekend brunch. Trust me, your family and friends will be begging you for the recipe after just one bite.

Remember these tips, and it’ll be perfect every time. 

  • Room temperature. Ensure the butter, eggs, and sour cream are at room temperature before mixing the batter to ensure a smooth, well-combined cake.
  • Refrigerate the streusel. Chill the streusel mixture before using it to help maintain its crumbly texture during baking.
  • Toss the blueberries in four. It keeps them from sinking to the bottom during baking.
  • Use frozen fruit. Don’t thaw it, toss it with the flour as instructed, but don’t mix it into the batter. Instead, sprinkle them over the batter, under the streusel, and bake as normal.
  • Test for doneness. Insert a toothpick into the center of the cake. If it comes out clean, the cake is ready. If there’s still wet batter, it needs more time.
  • Cool before glazing. Let the cake cool for at least 20 minutes on a wire rack before drizzling on the glaze. This allows the cake to set.
  • Add cream cheese. Blend 4 ounces of cream cheese into the glaze, with extra milk, for a tasty cream cheese frosting.
  • Variations. Try swapping the blueberries for other berries like raspberries or blackberries. You can also add lemon zest to the batter for a bright citrus flavor that complements the blueberries.
