Ingredients You’ll Need

3 cups (510 g) fresh blueberries: These juicy gems burst with flavor; make sure they’re plump and ripe for maximum sweetness.
3/4 cup (168 g) unsalted butter, softened: Gives the cake its rich texture; always use room temperature butter for easy creaming.
1 cup (200 g) granulated white sugar: Sweetens the cake beautifully; don’t skip this for the perfect flavor balance.
1 cup (220 g) light brown sugar, packed: Adds a deeper, caramel-like flavor that complements the blueberries.
3 cups (375 g) all-purpose flour, spooned and leveled: Provides structure to the cake; spoon and level for accuracy.
3/4 tsp salt: Enhances the sweetness and depth of flavors; don’t omit it!
2 tbsp (28 g) unsalted butter, softened: This smaller portion adds to the streusel topping; again, room temperature is key.
1/2 cup (110 g) light brown sugar, packed: Helps form the crumbly texture of the streusel; the slight moisture here is essential.
2 tsp cinnamon: A warm spice that elevates the flavor profile; feel free to adjust to taste.
1 tsp baking soda: Provides the lift and helps create that perfect crumb.
1 cup (240 ml) buttermilk, at room temperature: Keeps the cake moist and tender; if you’re out, regular milk can work in a pinch.
1 egg, at room temperature: Binds ingredients together while adding moisture; room temperature eggs mix better.
1 tbsp vanilla: Adds a lovely aromatic depth; high-quality pure vanilla extract is best.
1 cup (130 g) powdered sugar: For the sweet icing; be sure to sift it for a smooth drizzle.
3-5 tsp whole milk: Adjusts the consistency of the icing; a little goes a long way.

How to Make Blueberry Coffee Cake

Preheat the Oven: Start by preheating your oven to 350℉ (175 ℃). Grease a 9×9 inch pan and line it with parchment paper for easy removal later.
Prepare the Blueberries: In a medium bowl, take 2 1/4 cups (382 g) of the fresh blueberries and toss them gently with 1 tbsp (8 g) of flour to coat. This helps prevent sinking in the batter. Set them aside for now while you prepare the batter.
Cream the Butter and Sugars: In a large mixing bowl, combine 3/4 cup (168 g) of softened unsalted butter, 1 cup (200 g) granulated white sugar, and 1 cup (220 g) of light brown sugar. Using an electric mixer, cream these together until they’re fluffy and well combined, about 2-3 minutes.
Mix the Dry Ingredients: Add in the 3 cups (375 g) of all-purpose flour and 3/4 tsp salt. Mix on low speed until everything just comes together; it should resemble little crumbs.
Make the Streusel: Remove 3/4 cup (125 g) of the crumb mixture and transfer it to a small bowl. To this smaller portion, mix in the 2 tbsp (28 g) of softened butter, 1/2 cup (110 g) of light brown sugar, and 2 tsp cinnamon until you achieve a crumbly texture. Set this aside.
Prepare the Buttermilk Mixture: In a measuring cup, combine the 1 tsp baking soda with the 1 cup (240 ml) of buttermilk. Stir until the baking soda dissolves; this will cause the buttermilk to expand, so use a large cup.
Combine Wet Ingredients: Add the buttermilk mixture, 1 egg, and 1 tbsp vanilla to the large bowl with the crumb mixture. Mix on medium speed until well combined; the batter should be smooth but don’t overmix!
Fold in the Blueberries: Gently fold the larger portion of blueberries into the batter using a rubber spatula, being careful not to mash them.
Pour the Batter: Transfer the batter to the prepared pan and smooth it out evenly with a spatula.
Add Toppings: Sprinkle the remaining 3/4 cup (128 g) of blueberries across the top, followed by the streusel mixture you made earlier. It’ll create a lovely crunchy layer on top.
Bake: Place the cake in the preheated oven and bake for 70-80 minutes, or until a toothpick inserted into the center comes out clean. You should notice a lovely golden top and fragrant aroma filling your kitchen.
Cool Down: Once baked, let the coffee cake cool in the pan on a wire rack for about 30 minutes. Then, lift it out using the parchment paper to continue cooling on the rack until it’s completely cooled.
Make the Icing: In a small bowl, mix together 1 cup (130 g) of powdered sugar and 3-5 tsp whole milk to create a pourable icing. Start with 3 tsp of milk and adjust as needed; you want it to drizzle smoothly without being too runny.
Drizzle and Slice: Once your coffee cake has cooled completely, drizzle the icing over the cake and cut it into 16 slices. Enjoy every bite of this delicious treat!

Storing & Reheating

Once your blueberry coffee cake has cooled, you can store it at room temperature in an airtight container for up to 3 days. For longer storage, wrap it tightly and refrigerate for up to a week, or freeze it for up to 3 months. To reheat, simply pop a slice in the microwave for about 15-20 seconds, or warm it in a preheated oven at 350℉ (175 ℃) for 10 minutes. Keep in mind that the texture may change slightly, but a quick warmth can help refresh that delightful taste.

Chef’s Helpful Tips

Avoid overmixing once you add the flour; this ensures a tender crumb.
Ensure your egg and buttermilk are at room temperature before mixing; it helps create a smoother batter.
If your streusel seems too dry, add a tiny bit more melted butter; it should clump together nicely.
If you like a touch more sweetness, consider adding an extra drizzle of icing right before serving.
Make it a day ahead! The flavors develop beautifully overnight in the refrigerator.

This blueberry coffee cake recipe is sure to become a family favorite, providing a warm, comforting hug in every slice. Don’t hesitate to experiment by adding lemon zest or a sprinkle of nuts for an added crunch. Remember that every bake is an opportunity to enjoy and share something wonderful. Take a moment to appreciate the mixture of flavors, textures, and the memories you’ll create while enjoying this delicious cake with your loved ones.

Recipe FAQs

Can I use frozen blueberries instead of fresh?

Absolutely! Frozen blueberries can be used in this recipe, but make sure to toss them directly in the flour without thawing first. This helps them maintain their shape and prevents them from making the batter too wet.

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

The best rule of thumb is to insert a toothpick into the center of the cake. If it comes out clean or with just a few moist crumbs, your cake is perfectly baked. Keep an eye on it during the last few minutes to avoid overbaking.

Can I make this coffee cake ahead of time?

Yes! You can prepare the batter the night before and store it in the fridge until you’re ready to bake. Just let it sit at room temperature for about 30 minutes before putting it in the oven.

How can I make this recipe gluten-free?

For a gluten-free version, substitute the all-purpose flour with a one-to-one gluten-free flour blend. Ensure that your other ingredients, such as baking soda and vanilla, are also gluten-free. Enjoy your tasty treat worry-free!
