How To Make the Blueberry Coffee Cake

Step 1: Make the Crumb Topping

In a small bowl, combine brown sugar, flour, cinnamon, and cold diced butter. Use a pastry cutter or fork to mix until crumbly. Set aside.

Step 2: Prepare the Batter Base

Cream together softened butter and granulated sugar until light and fluffy. This is crucial for a soft, well-aerated cake base.

Step 3: Add Eggs & Vanilla

Beat in the eggs one at a time, followed by the vanilla extract. Scrape the bowl to keep the texture even.

Step 4: Alternate Dry and Wet Ingredients

In a separate bowl, whisk flour, baking powder, baking soda, and salt. Alternate adding the dry mix and sour cream to the wet batter, mixing gently after each addition.

Step 5: Fold in Blueberries

Gently fold the blueberries into the batter with a spatula, taking care not to overmix or crush the berries.

Step 6: Assemble and Top

Spread the batter into a greased 9×13-inch baking dish. Sprinkle the crumb topping evenly over the surface.

Step 7: Bake to Perfection

Bake at 350°F (175°C) for 40–45 minutes, or until a toothpick inserted into the center comes out clean. Let it cool slightly before serving.

Serving and Storing Your Blueberry Coffee Cake

Serve this Blueberry Coffee Cake warm, ideally within an hour of baking, when the crumb topping is still crisp and the blueberries are juicy. Pair it with freshly brewed coffee or a glass of cold milk for the ultimate experience. It also makes a lovely addition to a weekend brunch table or holiday breakfast spread.

To store, let the cake cool completely before wrapping it in plastic wrap or transferring to an airtight container. It will keep at room temperature for up to 3 days, or in the fridge for up to a week. You can also freeze individual slices for up to 2 months—just reheat in the microwave or oven before serving.

Frequently Asked Questions

What kind of blueberries work best for this cake?

Both fresh and frozen blueberries work well. If using frozen, do not thaw them before adding to the batter to prevent bleeding.

Can I make this coffee cake ahead of time?

Yes! It actually tastes even better the next day. Just bake, cool, and cover tightly. Warm it up slightly before serving if desired.

How do I prevent the blueberries from sinking to the bottom?

Toss the blueberries in a tablespoon of flour before folding them into the batter. This helps suspend them throughout the cake.

Can I substitute Greek yogurt for sour cream?

Absolutely. Greek yogurt offers a similar tang and moisture, making it a great alternative.

What if I don’t have a 9×13 pan?

You can use two 8-inch square pans or a large round cake pan. Just adjust the baking time slightly and check for doneness with a toothpick.

Is the crumb topping necessary?

While technically optional, the crumb topping is a signature feature of this coffee cake. It adds incredible texture and cinnamon flavor that’s hard to resist.
