Ingredients You’ll Need

3 cups fresh blueberries: Fresh berries yield the best flavor. If you can’t find them, frozen blueberries work too; just add them straight to the batter without thawing.
3/4 cup unsalted butter, softened: It’s essential for a tender crumb. Ensure it’s at room temperature for easy creaming!
1 cup granulated white sugar: This granulated sugar helps balance the flavor and adds sweetness.
1 cup light brown sugar, packed: The added molasses in brown sugar gives a depth of flavor.
3 cups all-purpose flour, spooned and leveled: This recipe calls for regular all-purpose flour, but feel free to use a gluten-free alternative if needed.
3/4 tsp salt: A pinch enhances sweetness and balances the flavors beautifully.
2 tbsp unsalted butter, softened: Typically used for making the crumb topping; it adds richness.
1/2 cup light brown sugar, packed: Also used in the topping for that lovely, sweet crunch.
2 tsp cinnamon: Cinnamon offers a warm spice that complements the blueberries so well.
1 tsp baking soda: This is the leavening agent, contributing to the light texture.
1 cup buttermilk, at room temperature: The acidity in buttermilk enhances the flavor and interacts with the baking soda for a rise.
1 egg, at room temperature: Eggs bind the ingredients together and add moisture.
1 tbsp vanilla: Pure vanilla extract enhances the overall taste, bringing all the flavors together.
1 cup powdered sugar: This sweetens and gives the glaze a delightful finish.
3-5 tsp whole milk: Adjust the milk for the perfect glaze consistency; you want it pourable but not too runny.

How to Make Blueberry Coffee Cake

Prepare the Oven: Preheat your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan to prevent sticking.
Mix the Dry Ingredients: In a mixing bowl, whisk together 3 cups all-purpose flour, 3/4 tsp salt, and 1 tsp baking soda. Set it aside.
Cream the Butter and Sugars: In a large bowl, beat together 3/4 cup unsalted butter, 1 cup granulated white sugar, and 1 cup light brown sugar until fluffy and light in color, about 3-4 minutes.
Add Egg and Vanilla: Mix in 1 large egg and 1 tbsp vanilla extract until well combined.
Incorporate the Buttermilk: Gradually mix in 1 cup buttermilk into the butter-sugar mixture, alternating with the flour mixture. Begin and end with the flour mixture to maintain a smooth batter.
Fold in Blueberries: Gently fold in 3 cups fresh blueberries. Don’t worry if a few berries burst—their color adds to the cake’s charm!
Prepare the Topping: In a small bowl, combine 2 tbsp softened butter, 1/2 cup light brown sugar, 2 tsp cinnamon, and 3/4 cup of the reserved flour mixture, creating a crumbly texture.
Layer the Batter and Crumb: Pour half of the batter into the prepared baking pan, spread evenly. Add half of the crumble topping, followed by the remaining batter, and finally, top with the rest of the crumb mixture.
Bake the Cake: Bake in the preheated oven for 55-60 minutes, or until a toothpick inserted into the center comes out clean, and the edges are lightly golden.
Make the Glaze: While the cake cools, whisk together 1 cup powdered sugar and just enough whole milk (3-5 tsp) to achieve a drizzling consistency.
Drizzle & Enjoy: Once the cake has cooled, drizzle the glaze over the top. Slice, serve warm, and enjoy every bite!

Storing & Reheating

Blueberry Coffee Cake can be stored at room temperature for up to 2 days, covered with foil or plastic wrap to keep it fresh. For longer storage, transfer it to the fridge where it will last up to a week. If you prefer freezing, wrap slices tightly in plastic wrap and store in a freezer-safe container for up to 3 months. To reheat, pop individual slices in the microwave for about 15-20 seconds until warmed through. The texture will still hold up well, with flavors remaining delightful.

Chef’s Helpful Tips

Make sure all your ingredients are at room temperature, especially the butter and eggs, to help them cream properly for a light cake.
Avoid overmixing the batter once you add the flour to prevent a dense texture; mix just until combined.
If you notice your blueberries sinking, toss them gently in a bit of flour before adding them to the batter.
Feel free to add nuts or lemon zest to customize this cake to your taste!
This cake can easily be made ahead; just store it fully cooled and unglazed until you’re ready to serve.

Blueberry Coffee Cake is a comforting classic that’s perfect for any occasion. It’s easy to make, and the results are rewarding with its moist, flavorful layers and crumbly topping. Don’t shy away from experimenting with flavor additions like fresh lemon zest or a dash of almond extract. Nothing beats that warm, cozy feeling of serving a delicious homemade cake to friends and family.

Recipe FAQs

Can I use frozen blueberries instead of fresh?

Absolutely! Frozen blueberries work wonderfully as a substitute. Just add them directly to the batter without thawing, as this helps to maintain their shape and flavor during baking.

How do I know when my cake is done baking?

The best way to check for doneness is to insert a toothpick into the center of the cake. It should come out clean or with a few moist crumbs, not wet batter. Also, the edges should be golden and the top should spring back when lightly touched.

Can I make this recipe dairy-free?

Yes! You can replace the buttermilk with a dairy-free alternative, such as almond milk or coconut milk, mixed with a tablespoon of vinegar to mimic buttermilk’s acidity. Just ensure you also use dairy-free butter for the cake and the topping.

How can I add more flavor to my Blueberry Coffee Cake?

For a flavor boost, consider adding lemon zest to the batter or replacing the vanilla extract with almond extract. You can also incorporate chopped nuts, like walnuts or pecans, into either the batter or the crumb topping for added texture.
