Ingredients You’ll Need

2 cups all-purpose flour: The base for our cake, providing structure. You could substitute with gluten-free flour if needed, but the texture might differ.
2 cups blueberries: Fresh blueberries are best for their burst of flavor. If using frozen, do not thaw to avoid excess moisture.
3 teaspoons baking powder: This ensures our cake rises beautifully and has a light texture.
½ teaspoon salt: Enhances the flavors and balances the sweetness.
½ cup unsalted butter, softened: Adds richness and moisture. Remember to bring it to room temperature for easier mixing.
½ cup granulated sugar: Sweetens the base of the cake, creating that delightful balance.
1 large or x-large egg: Binds the ingredients together and adds moisture.
1 teaspoon pure vanilla extract: A classic flavor enhancer that adds depth.
½ cup sour cream: Contributes to a moist crumb and a slight tang. If you need a substitute, plain Greek yogurt works well.
½ cup milk: Brings everything together and adds moisture.
2 tablespoons lemon zest: Adds a vibrant citrus flavor that brightens the cake.
½ cup all-purpose flour: Used for the streusel topping, contributing to its crumbly texture.
⅓ cup light brown sugar packed: Adds sweetness with a hint of caramel flavor in the crumb topping.
1 teaspoon ground cinnamon: Warm and aromatic, it layers in depth of flavor.
¼ teaspoon salt: Balances the sweetness in the streusel.
¼ cup unsalted butter, melted: Binds the streusel, creating that lovely crumbly topping.
½ cup powdered sugar: Used for the glaze for a sweet finish.
2 tablespoons lemon juice: The zingy counterpart to the powdered sugar in the glaze.

How to Make Lemon Blueberry Coffee Cake

Preheat the Oven: Begin by preheating your oven to 350 degrees F. While it warms up, lightly grease the bottom and sides of a 9-inch round springform pan. This will ensure our cake comes out flawlessly.
Prepare the Streusel: In a small bowl, combine ½ cup all-purpose flour, ⅓ cup light brown sugar, 1 teaspoon ground cinnamon, and ¼ teaspoon salt. Add the melted butter and mix with a fork until it forms a crumbly mixture. Set this delightful mixture aside.
Coat the Blueberries: In another small bowl, take 1½ cups of blueberries and toss them with 1 tablespoon of flour. This simple step helps prevent them from sinking in the batter. Set them aside, too.
Mix Dry Ingredients: In a large bowl, whisk together the remaining 2 cups of all-purpose flour, 3 teaspoons baking powder, and ½ teaspoon salt. This creates an even mixture for the cake base.
Cream Butter & Sugar: In a separate large bowl, beat the softened butter and ½ cup granulated sugar using an electric mixer on medium-high speed for about 2-3 minutes until light and fluffy. Then, add the egg, sour cream, lemon zest, milk, and 1 teaspoon pure vanilla extract. Mix on medium-low until everything is well combined.
Combine Wet & Dry Ingredients: Gradually add the flour mixture to the wet ingredients, mixing until just combined. Be careful—you want to avoid overmixing, which can toughen your cake.
Fold in Blueberries: With a rubber spatula, gently fold in the coated blueberries, ensuring they’re evenly distributed throughout the batter. The batter will be thick, but that’s perfect!
Assemble the Cake: Spread the batter into the prepared springform pan and smooth it with the spatula. Top with the remaining blueberries and sprinkle the streusel mixture evenly over the top.
Bake: Bake in your preheated oven for 45-55 minutes. You’ll know it’s done when a toothpick inserted in the center comes out clean, and the edges are golden. Let it cool on a wire rack for about 20 minutes before carefully removing the springform ring. Allow it to cool completely for at least an hour before slicing.
Glaze (Optional): If you’d like to add a sweet finish, mix the powdered sugar with 2 tablespoons lemon juice until smooth. Drizzle it over the cooled cake before serving.

Storing & Reheating

To store your Lemon Blueberry Coffee Cake, cover it tightly at room temperature for up to 3 days. If you need to keep it longer, refrigerate it for up to a week in an airtight container. For longer storage, slice the cake and wrap it well in plastic wrap or aluminum foil, followed by a freezer-safe bag for up to 3 months. When ready to enjoy, thaw in the refrigerator overnight and reheat individual slices in the microwave for about 15-20 seconds. Keep in mind the texture will remain tender, though the flavor may mellow.

Chef’s Helpful Tips

Be sure to measure your flour correctly! Spoon it into your measuring cup and level it off to avoid a dense cake.
If your butter is too soft, it might not incorporate well. Aim for a slightly softened but still cool temperature.
To prevent your blueberries from bleeding, work quickly and avoid crushing them while folding.
If using frozen blueberries, no need to thaw, but add an extra minute or two to the baking time.
Experiment with different citrus zest, such as orange or lime, for a unique twist!

Recipe FAQs

Can I make this cake ahead of time?

Absolutely! You can bake it up to two days in advance. Just store it covered at room temperature and slice it just before serving. If you’d like to prepare the batter ahead, you could do that too, but bake it fresh.

Can I use other fruits?

Certainly! While blueberries pair beautifully with lemon, feel free to try raspberries, blackberries, or even diced strawberries. Adjust cooking time slightly if you use larger fruits.

Why did my cake sink in the middle?

A sinking cake can result from several factors like overmixing the batter, using too much leavening agent, or not baking it long enough. Always check for doneness a few minutes earlier than the recipe states if you’re unsure.

How can I adapt this recipe to be gluten-free?

You can substitute the all-purpose flour with a 1:1 gluten-free flour blend. Just ensure that it contains xanthan gum, as this will help mimic the texture of traditional flour.
