Ingredients You’ll Need

3 cups fresh blueberries: These juicy gems provide natural sweetness and moisture. If fresh isn’t available, frozen will work; just don’t thaw them beforehand.
3/4 cup unsalted butter, softened: This creates a tender crumb. Be sure it’s at room temperature for easy mixing.
1 cup granulated white sugar: Sweetens the batter, creating a perfect balance with the tart blueberries.
1 cup light brown sugar, packed: Adds rich flavor and depth to the cake.
3 cups all-purpose flour, spooned and leveled: Forms the base of the cake. Use a measuring cup to spoon and level to avoid a dense texture.
3/4 tsp salt: Enhances the flavors in the batter.
2 tbsp unsalted butter, softened (for topping): Creates that delicious crumb topping.
1/2 cup light brown sugar, packed (for topping): A sweet crunch that balances the tartness of the blueberries.
2 tsp cinnamon: Adds warmth and spice.
1 tsp baking soda: Leavening agent that gives the cake its rise.
1 cup buttermilk, at room temperature: Ensures the cake is moist and soft. If you don’t have buttermilk, mix 1 cup of milk with 1 tbsp of vinegar and let it sit for 5 minutes.
1 egg, at room temperature: Provides structure and moisture.
1 tbsp vanilla: Deepens the flavor profile.
1 cup powdered sugar: For a sweet glaze that perfectly complements the cake’s texture.
3-5 tsp whole milk: Adjust as needed to reach your desired glaze consistency.

How to Make Blueberry Coffee Cake

Preheat Your Oven: Preheat your oven to 350°F (175°C). Greasing a 9×13-inch baking dish with butter or lining it with parchment paper will help ensure an easy release.
Prepare the Blueberries: Gently rinse your 3 cups of fresh blueberries and pat them dry. Toss them in a teaspoon of all-purpose flour to help prevent them from sinking to the bottom while baking.
Make the Batter: In a large bowl, cream together 3/4 cup softened unsalted butter, 1 cup granulated sugar, and 1 cup light brown sugar until it’s light and fluffy. This process should take about 2-3 minutes. Add the egg, 1 tbsp vanilla, and 1 cup room temperature buttermilk, mixing until just combined.
Combine the Dry Ingredients: In another bowl, whisk together the 3 cups all-purpose flour, 3/4 tsp salt, 1 tsp baking soda, and 2 tsp cinnamon. Gradually add the dry ingredients to the wet mixture, stirring until everything is just combined—be careful not to overmix; a few lumps are okay.
Fold in Blueberries: Gently fold the floured blueberries into the batter with a spatula. This step is crucial for keeping the blueberries intact.
Prepare the Topping: In a small bowl, blend the 2 tbsp softened unsalted butter, 1/2 cup light brown sugar, 2 tsp cinnamon, and 1 cup all-purpose flour until crumbly. Set this aside.
Assemble the Cake: Pour half of the batter into the prepared baking dish. Sprinkle with half of the crumb topping. Add the remaining batter and top it with the rest of the crumb mixture, spreading it evenly over the top.
Bake: Bake in your preheated oven for around 45-50 minutes, or until the edges begin to turn golden and a toothpick inserted into the center comes out clean.
Cool and Glaze: Allow the cake to cool for about 15-20 minutes. While it cools, make the glaze by mixing the 1 cup powdered sugar with enough whole milk (3-5 tsp) to reach a pourable consistency. Drizzle it over the cooled cake.

Storing & Reheating

To maintain the freshness of your blueberry coffee cake, store it at room temperature in an airtight container for up to three days. For longer storage, refrigerate it for up to a week, or freeze it for up to three months in a freezer-safe container. When you’re ready to enjoy it again, simply warm individual slices in the microwave for about 15-20 seconds. Note that while the flavor remains fantastic, the texture may soften slightly after freezing, but a quick reheating can revive its delightfulness.

Chef’s Helpful Tips

Make sure your butter is fully softened; this is key for a fluffy cake.
For room temperature eggs, simply place them in warm water for about 5-10 minutes before using them.
Try not to overmix your batter; it results in a denser cake.
To enhance flavor, consider adding a squeeze of lemon juice to your blueberries before mixing them in.
If you’re short on time, you can prepare the batter a day in advance and refrigerate it overnight before baking.

Blueberry coffee cake is a fantastic option for brunches, tea parties, or just a cozy treat at home. Its delightful balance of sweetness and warmth makes it a crowd favorite. Don’t hesitate to experiment with different toppings, like nuts or coconut, or even different fruits. Enjoy the baking experience as much as the flavor!

Recipe FAQs

Can I use frozen blueberries instead of fresh?

Absolutely! Frozen blueberries work well, but it’s best to use them straight from the freezer without thawing. Note that they may tint the batter a bit more, which can look lovely.

How can I make this recipe gluten-free?

You can substitute the all-purpose flour with a gluten-free flour blend. Be sure to include a binding agent like xanthan gum if your blend doesn’t include it already.

What can I do with leftovers?

Leftover blueberry coffee cake can be enjoyed for breakfast, as an afternoon snack, or even as a dessert. It pairs perfectly with ice cream for a delightful evening treat.

How can I ensure a moist cake?

Using buttermilk is key for moisture. Also, be careful not to overbake; removing the cake when a toothpick comes out with a few crumbs attached will keep it moist and fluffy.
