Ingredients You’ll Need

3 cups fresh blueberries: Choose plump, juicy berries for the best flavor. If fresh isn’t available, frozen can still work, but don’t thaw them before adding.
3/4 cup unsalted butter, softened: This adds richness to the cake. Always use unsalted to control the saltiness.
1 cup granulated white sugar: This sweetens the cake and helps create a lovely texture.
1 cup light brown sugar, packed: It brings caramel notes and moisture to the cake.
3 cups all-purpose flour, spooned and leveled: Essential for structure. Spoon flour into the measuring cup rather than scooping to avoid overpacking.
3/4 tsp salt: Balances the sweetness and enhances overall flavor.
2 tbsp unsalted butter, softened: Used in the topping to create a delightful crumbly texture.
1/2 cup light brown sugar, packed: This is combined with cinnamon for the topping.
2 tsp cinnamon: Warm spices that bring a comforting flavor to the cake.
1 tsp baking soda: It helps the cake rise beautifully.
1 cup buttermilk, at room temperature: Adds moisture and a slight tang; if you don’t have buttermilk, mix 1 cup milk with a tablespoon of vinegar and let it sit for 10 minutes.
1 egg, at room temperature: Provides structure and richness.
1 tbsp vanilla: A must for flavor enhancement.
1 cup powdered sugar: For a sweet glaze that finishes the cake nicely.
3-5 tsp whole milk: To reach the desired glaze consistency.

How to Make Blueberry Coffee Cake

Preheat the Oven: Begin by preheating your oven to 350°F (175°C). Grease a 9×13 inch baking dish with butter to prevent sticking.
Prepare the Topping: In a small bowl, combine 2 tablespoons of softened butter, 1/2 cup brown sugar, and 2 teaspoons of cinnamon. Mix until crumbly and set aside.
Cream the Butter and Sugars: In a large mixing bowl, beat together 3/4 cup of softened unsalted butter, 1 cup of granulated white sugar, and 1 cup of packed light brown sugar until light and fluffy, about 3-4 minutes.
Add the Egg and Vanilla: Beat in 1 room-temperature egg and 1 tablespoon of vanilla extract until well incorporated.
Mix the Dry Ingredients: In a separate bowl, whisk together 3 cups of all-purpose flour, 3/4 teaspoon of salt, and 1 teaspoon of baking soda. Gradually add this to the butter mixture, alternating with 1 cup of buttermilk, starting and finishing with the flour mixture.
Fold in the Blueberries: Gently fold in 3 cups of fresh blueberries, being careful not to crush them.
Combine Batter and Topping: Pour the batter into the prepared baking dish, smoothing the top with a spatula. Sprinkle the topping evenly over the batter.
Bake the Cake: Bake in the preheated oven for 45-50 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out clean.
Cool and Prepare Glaze: Allow the cake to cool in the pan for about 10 minutes. Meanwhile, mix 1 cup powdered sugar with 3-5 teaspoons of whole milk until you reach your desired glaze consistency.
Drizzle the Glaze: Once the cake has cooled slightly, drizzle the glaze over the top. Allow the cake to cool completely before slicing and serving.

Storing & Reheating

To store leftover Blueberry Coffee Cake, keep it in an airtight container at room temperature for up to 2 days. You can refrigerate it for up to a week, but ensure it’s covered well to maintain moisture. If you want to freeze it, wrap individual slices tightly in plastic wrap and then in aluminum foil; it can last for up to 3 months. To enjoy, thaw overnight in the refrigerator and reheat in the microwave for about 10-15 seconds, or until warmed through. The texture will remain delightful but may be slightly denser after freezing.

Chef’s Helpful Tips

Avoid overmixing your batter once you add the flour, as this can make the cake tough. Mix until just combined.
Make sure your ingredients, especially the egg and buttermilk, are at room temperature for a smoother batter.
If you desire a little extra blueberry flavor, consider adding a handful of finely chopped blueberries into the batter as well.
Test your cake for doneness by inserting a toothpick. If it comes out with just a few moist crumbs, it’s perfect!
For a unique twist, consider adding lemon zest to the batter or glaze for a refreshing pop of flavor.

As you prepare this Blueberry Coffee Cake, remember the joy that comes not just from baking but from sharing it with others. Its inviting aroma and comforting flavor make every occasion special. Feel free to add your personal touch to the recipe, whether that’s swapping out the blueberries for another berry or adding a sprinkle of nuts on top. Baking is about experimenting and having fun, so don’t hesitate to play around!

Recipe FAQs

Can I use frozen blueberries instead of fresh?

Absolutely! While fresh blueberries are delicious, frozen blueberries work perfectly too. Just make sure to keep them frozen until you’re ready to mix them into the batter to prevent them from bleeding color.

What can I serve with Blueberry Coffee Cake?

Pair it with a warm cup of coffee or tea for a delightful breakfast or brunch. It can also be served with whipped cream or ice cream for a delightful dessert.

Can I make this coffee cake in advance?

Yes, you can prepare the batter and store it in the refrigerator for up to a day before baking. Just ensure to bring it to room temperature before placing it in the oven for even cooking.

How do I know when my coffee cake is done baking?

Your Blueberry Coffee Cake is done when the edges are golden brown and a toothpick inserted in the center comes out clean or with just a few moist crumbs attached. Keep an eye on it in the last few minutes of baking to ensure it doesn’t overbake!

Instructions

Preheat the oven to 350℉ (175 ℃). Grease a 9×9 in pan and line it with parchment paper.
In a medium bowl, toss 2 1/4 cups (382 g) of blueberries with 1 tbsp (8 g) of flour and set aside. The remaining blueberries will be for topping the cake.
In a large bowl, cream together the softened butter, granulated sugar, and packed brown sugar using an electric mixer.
Add the flour and salt to the mixture, mixing on low speed until it resembles crumbs.
Remove 3/4 cup (125 g) of this mixture to a small bowl. To this smaller mixture, add the softened butter, light brown sugar, and cinnamon, mixing until combined, creating large clumps for the streusel.
Mix baking soda into buttermilk until dissolved, being cautious of expansion.
Combine the buttermilk mixture, egg, and vanilla into the larger mixture and mix on medium speed until well combined.
Gently fold in the larger portion of blueberries into the batter using a rubber spatula.
Pour the batter into the prepared pan and spread it evenly.
Top with the remaining blueberries and sprinkle the streusel mixture on top.
Bake for 70-80 minutes or until a toothpick inserted in the center comes out clean.
Cool the cake in the pan on a wire rack for 30 minutes, then transfer to cooling rack to cool completely.
Mix powdered sugar with enough milk to create a pourable icing.
Drizzle the icing over the cooled cake and cut into 16 slices.

Notes

For best results, use fresh blueberries. Frozen blueberries may release too much liquid.
Ensure the cake is completely cooled before applying the icing for a better presentation.
Store any leftovers in an airtight container at room temperature.
