Ingredients You’ll Need

3 cups fresh blueberries: These juicy gems are the star of the show and provide a burst of flavor. If you can’t find fresh berries, frozen blueberries work too; just make sure to thaw them beforehand.
3/4 cup unsalted butter, softened: Richness is key to a moist cake, and soft butter blends beautifully into the batter. Make sure it’s at room temperature for best results.
1 cup granulated white sugar: This sweetener helps to create a tender crumb and balances the flavors.
1 cup light brown sugar, packed: Adds depth and a touch of caramel flavor; it’s essential for that perfect coffee cake texture.
3 cups all-purpose flour, spooned and leveled: Provides the structure for your cake. Spoon it lightly into your measuring cup to avoid excess flour, which can lead to a dense result.
3/4 tsp salt: A little salt enhances all the flavors.
2 tbsp unsalted butter, softened (for crumb topping): This extra butter helps create the delicious crumb topping that adds texture.
1/2 cup light brown sugar, packed (for crumb topping): This will heighten the sweetness and deepen the topping’s flavor.
2 tsp cinnamon: Warming and fragrant, it elevates the cake and compliments the berries beautifully.
1 tsp baking soda: Helps the cake rise and stay light and fluffy.
1 cup buttermilk, at room temperature: The acidity adds moisture and helps the cake rise beautifully. If you don’t have buttermilk, you can make a quick substitute with regular milk and a splash of vinegar.
1 egg, at room temperature: This binds the ingredients together and enriches the flavor.
1 tbsp vanilla extract: Adds a sweet, aromatic background that elevates the flavor profile.
1 cup powdered sugar: Used for glazing this coffee cake and adding a sweet finishing touch.
3-5 tsp whole milk: This will help you achieve the desired glaze consistency.

How to Make Blueberry Coffee Cake

Preheat the Oven: Start by preheating your oven to 350°F (175°C). Grease a 9×13 inch baking dish so your cake comes out easily.
Prepare the Crumb Topping: In a small bowl, mix together 2 tablespoons of softened unsalted butter, 1/2 cup light brown sugar, 2 teaspoons cinnamon, and 3/4 cup all-purpose flour until crumbly. Set this aside.
Mix the Batter: In a large mixing bowl, cream together 3/4 cup softened unsalted butter, 1 cup granulated sugar, and 1 cup light brown sugar until fluffy.
Add Egg & Vanilla: Beat in the egg and 1 tablespoon of vanilla extract until fully incorporated.
Combine Dry Ingredients: In another bowl, whisk together 3 cups all-purpose flour, 3/4 teaspoon salt, and 1 teaspoon baking soda.
Mix Wet and Dry: Gradually add the dry mixture to the wet mixture, alternating with 1 cup of buttermilk. Mix until just combined—don’t overmix!
Fold in the Blueberries: Gently fold in the fresh blueberries; be cautious to not break them up too much.
Layer the Batter: Pour half of the batter into the prepared baking dish, spread evenly. Spoon the crumb topping over this layer, and then add the remaining batter on top, smoothing it out.
Sprinkle the Topping: Generously sprinkle any remaining crumb topping over the top layer of batter.
Bake: Bake for 50-55 minutes, or until a toothpick inserted comes out clean and the edges are golden brown. You should smell the delightful scent filling your kitchen!
Cool and Glaze: Let the cake cool for about 10 minutes. For the glaze, whisk together 1 cup powdered sugar and 3-5 teaspoons whole milk until smooth, adjusting the milk for desired consistency. Drizzle over the warm cake.

Storing & Reheating

Store any leftover Blueberry Coffee Cake at room temperature for up to 2 days, covered with foil or in an airtight container to keep it fresh. If you’d like to keep it longer, refrigerate it for up to a week. You can also freeze individual pieces in freezer-safe bags for up to 3 months. For reheating, pop your slice in the microwave for about 15-20 seconds or until warmed through; this will help revive its moistness.

Chef’s Helpful Tips

Be careful not to overmix your batter after adding the flour; this can lead to a tougher cake.
Make sure your ingredients are at room temperature for the best texture and flavor.
To make it ahead, you can bake the coffee cake the day before and refrigerate it; just warm it in the oven before serving.
Use a light touch when folding the blueberries into the batter to prevent them from breaking.
If you prefer, you can swap half of the blueberries with raspberries for a fruity twist!

This Blueberry Coffee Cake is sure to become a cherished part of your recipe collection. It offers a perfect blend of flavor, texture, and simplicity that can light up any gathering. Whether enjoyed with a morning cup of coffee or as an afternoon indulgence, each slice is a little piece of happiness. I encourage you to get in the kitchen, make this delicious cake, and share the joy with family and friends. You’ll be so glad you did!

Recipe FAQs

Can I use frozen blueberries instead of fresh?

Absolutely! You can use frozen blueberries in place of fresh. Just be sure to thaw and drain them before folding them into the batter to avoid excess moisture.

What can I substitute for buttermilk?

If you don’t have buttermilk, you can make a quick substitute by mixing 1 cup of milk with 1 tablespoon of vinegar or lemon juice. Let it sit for about 5-10 minutes before using.

How do I know when my coffee cake is done?

Your coffee cake is ready when the edges are golden, and a toothpick inserted into the center comes out clean. If the cake starts to brown too quickly, you can cover it with aluminum foil towards the end of baking.

Can I make this coffee cake dairy-free?

Yes! You can substitute the unsalted butter with a dairy-free alternative and use a non-dairy milk, such as almond or soy milk, for the buttermilk. Just be sure to use dairy-free powdered sugar for the glaze as well.

Instructions

Preheat the oven to 350℉ (175 ℃). Grease a 9×9-inch pan and line with parchment paper.
In a medium bowl, toss 2 1/4 cups (382 g) of blueberries with 1 tbsp (8 g) of flour; set aside. Reserve the remaining blueberries for topping.
In a large bowl, cream the softened butter, granulated sugar, and brown sugar with an electric mixer.
Add flour and salt, mixing on low speed until crumbly.
Remove 3/4 cup (125 g) of the mixture to a small bowl. To this, add the remaining butter, brown sugar, and cinnamon; mix until clumpy and set aside for streusel.
Dissolve baking soda in buttermilk and add to the larger bowl along with the egg and vanilla; mix until combined.
Gently fold in the larger portion of blueberries with a rubber spatula into the batter.
Spread the batter into the prepared pan evenly.
Top with remaining blueberries and streusel mixture.
Bake for 70-80 minutes until a toothpick comes out clean.
Cool in the pan on a wire rack for 30 minutes; pull up on parchment to release the cake and cool completely.
Mix powdered sugar with milk in a small bowl until pourable; drizzle over cooled cake and slice into 16 pieces.

For added flavor, consider adding lemon zest to the batter.
