Ingredients You’ll Need

3 cups (510 g) fresh blueberries: The star of the show! Fresh blueberries burst with flavor and moisture, but you can also use frozen—just ensure they’re thawed and drained.
3/4 cup (168 g) unsalted butter, softened: Adds richness and moisture to the cake. If you run out of unsalted butter, you can use salted; just reduce the added salt slightly.
1 cup (200 g) granulated white sugar: Balances the tartness of the blueberries. If desired, you could substitute coconut sugar for a more caramel-like sweetness.
1 cup (220 g) light brown sugar, packed: This introduces a hint of molasses flavor, enhancing the cake’s overall taste. If you don’t have light brown sugar, regular brown sugar will work too.
3 cups (375 g) all-purpose flour, spooned and leveled: Provides the structure of the cake. For a gluten-free option, try using a gluten-free flour blend.
3/4 tsp salt: Essential for balancing sweetness. If you’re watching your sodium intake, you can reduce this slightly.
2 tbsp (28 g) unsalted butter, softened: Used for greasing the pan to ensure an easy release.
1/2 cup (110 g) light brown sugar, packed: This is for the crumb topping, giving it that crunchy sweetness. Dark brown sugar will create a richer topping.
2 tsp cinnamon: Adds warmth and depth to the flavor.
1 tsp baking soda: Helps the cake rise and become airy.
1 cup (240 ml) buttermilk, at room temperature: Contributes to the cake’s moistness. If you don’t have buttermilk, you can make a substitute using milk and vinegar or lemon juice.
1 egg, at room temperature: Binds the ingredients and adds moisture. Room temperature eggs mix better with cold ingredients.
1 tbsp vanilla: For a lovely aromatic flavor that rounds out the cake.
1 cup (130 g) powdered sugar: For the finishing glaze, it adds sweetness and a beautiful shine.
3-5 tsp whole milk: Used to thin the powdered sugar for the glaze; you can substitute with a non-dairy milk if needed.

How to Make Blueberry Coffee Cake

Preheat the Oven: Begin by preheating your oven to 350°F (175°C). This will ensure your cake bakes evenly.
Prepare the Pan: Grease a 9×13-inch baking pan with 2 tablespoons of softened unsalted butter for easy release later.
Mix the Dry Ingredients: In a large bowl, whisk together 3 cups all-purpose flour, 3/4 tsp salt, 2 tsp cinnamon, and 1 tsp baking soda.
Cream the Butter and Sugars: In a separate bowl, using an electric mixer, cream together 3/4 cup unsalted butter, 1 cup granulated sugar, and 1 cup packed light brown sugar until it’s fluffy and light—about 2 minutes.
Add the Egg and Vanilla: Beat in 1 egg and 1 tbsp vanilla until incorporated.
Incorporate Dry Ingredients: Gradually mix the dry ingredients into the butter-sugar mixture, alternating with 1 cup buttermilk. Start and end with the dry ingredients. The batter will be thick.
Fold in the Blueberries: Gently fold in 3 cups fresh blueberries with a spatula, being careful not to break them.
Pour into Pan: Spread the batter evenly in the prepared pan, smoothing the top gently.
Prepare the Crumb Topping: In a small bowl, mix together 1/2 cup packed light brown sugar, 2 tbsp unsalted butter, and 1/2 cup of flour until crumbly. Sprinkle this mixture evenly over the batter.
Bake the Cake: Place the pan in the oven and bake for 50-60 minutes or until the cake is golden brown and a toothpick inserted in the center comes out clean. The aroma will be irresistible!
Let it Cool: Once out of the oven, allow the cake to cool in the pan for about 10-15 minutes before transferring it to a wire rack to cool completely.
Make the Glaze: In a small bowl, whisk together 1 cup powdered sugar and enough whole milk (3-5 tsp) until it reaches your desired consistency for drizzling.
Drizzle and Serve: Once the cake is cooled, drizzle the glaze over the top, slice it up, and serve this delicious blueberry coffee cake.

Storing & Reheating

To store your blueberry coffee cake, cover it tightly with plastic wrap and keep it at room temperature for up to two days. For longer storage, refrigerate it in an airtight container for up to a week. If you want to keep it for an extended period, you can freeze it for up to three months. To reheat, simply pop a slice in the microwave for about 15-20 seconds or warm it in a toaster oven until it’s just heated through. The texture may slightly change, so adding a teaspoon of milk before reheating can help refresh it.

Chef’s Helpful Tips

Be cautious when combining the blueberries with the batter; fold gently to prevent them from breaking apart.
Using room temperature eggs and buttermilk helps incorporate these ingredients more evenly, leading to a lighter cake.
If you find the cake is too dense, check your measurement of flour; spooning and leveling ensure you have just the right amount.
Experiment with adding nuts or a lemon zest to the topping for a refreshing twist.
This cake can be made a day ahead—just glaze it right before serving for that fresh, delightful presentation.

Feel free to explore variations and make this recipe your own. A blueberry coffee cake is not just a treat; it invites creativity, allowing you to add personal touches that reflect your taste.

Recipe FAQs

Can I use frozen blueberries for this recipe?

Absolutely! You can use frozen blueberries in place of fresh ones. Just make sure to thaw and drain them to avoid excess moisture in the batter, which could affect the texture of the cake.

How should I store leftovers?

Store any leftover blueberry coffee cake by wrapping it tightly in plastic wrap or placing it in an airtight container. It will stay fresh at room temperature for 2 days or in the refrigerator for up to a week.

Can I make this coffee cake gluten-free?

Yes, you can substitute the all-purpose flour with a gluten-free flour blend. Just make sure it contains a binding agent like xanthan gum for the best results.

How can I enhance the flavor of the cake further?

For an extra flavor boost, consider adding a teaspoon of lemon zest to the batter before mixing in the blueberries. The citrus will complement the berries beautifully.
