Why You’ll Love This Blueberry Coffee Cake

This recipe hits the sweet spot of cozy and bright. The sour cream base gives the cake a soft, moist crumb that holds together beautifully, while the streusel topping adds a slightly crisp texture. It’s not overly sugary, making it a favorite for those who want a cake that’s satisfying but not cloying. The best part? You can use fresh or frozen blueberries, so it’s easy to make year-round.

Can I Use Frozen Blueberries for Coffee Cake?

Absolutely. While fresh blueberries provide a brighter flavor and firmer texture, frozen blueberries are an excellent alternative—especially when fresh ones aren’t in season. If using frozen, don’t thaw them first. Toss them in a little flour before folding into the batter to keep them from sinking to the bottom. This trick helps distribute them more evenly throughout the cake.

Ingredients for the Blueberry Coffee Cake

The beauty of this coffee cake lies in how basic the ingredients are, yet how indulgent it tastes. Each one plays a specific role in creating that bakery-style texture and flavor you love.

All-purpose flour: Forms the structure of the cake and streusel topping.
Granulated sugar: Sweetens both the batter and the topping.
Light brown sugar: Adds depth and richness to the crumb topping.
Unsalted butter: Creates a moist cake and a rich, crumbly topping.
Baking powder: Provides the lift for a fluffy texture.
Baking soda: Works with the sour cream to give even more rise.
Salt: Balances the sweetness and enhances flavor.
Sour cream: Adds moisture and a subtle tang to the batter.
Egg: Binds the ingredients and gives the cake structure.
Vanilla extract: Lends a warm, aromatic base.
Fresh or frozen blueberries: Bring the pop of fruit and sweetness.

How To Make the Blueberry Coffee Cake

Step 1: Prepare the Crumb Topping

In a bowl, combine flour, light brown sugar, granulated sugar, and a pinch of salt. Cut in cold butter until the mixture resembles coarse crumbs. Set aside in the fridge while you prepare the cake.

Step 2: Make the Batter

In a separate bowl, whisk together the flour, baking powder, baking soda, and salt. In another bowl, beat softened butter and sugar until light and fluffy. Add the egg, then mix in the sour cream and vanilla extract.

Step 3: Combine Wet and Dry

Gradually add the dry ingredients to the wet, mixing just until combined. Be careful not to overmix, or the cake could turn dense.

Step 4: Fold in the Blueberries

Gently fold in your blueberries with a spatula, making sure they are evenly distributed throughout the batter.

Step 5: Assemble and Bake

Pour the batter into a greased baking pan and spread evenly. Sprinkle the crumb topping generously over the top. Bake at 350°F (175°C) for about 35–40 minutes, or until a toothpick inserted into the center comes out clean.

How to Serve and Store This Blueberry Coffee Cake

This blueberry coffee cake is best served warm or at room temperature, and it feeds 8 to 10 people comfortably. You can cut it into generous squares for brunch spreads, wrap individual portions for breakfast-on-the-go, or serve with a scoop of vanilla ice cream for dessert.

To store, keep it covered at room temperature for up to two days, or refrigerate for up to five days. You can also freeze it—wrap slices tightly in plastic wrap and freeze in an airtight container for up to two months. Thaw at room temperature or warm briefly in the oven or microwave before serving.

What to Serve With Blueberry Coffee Cake?

Coffee or Espresso
