Directions

Make the streusel topping: Combine the brown sugar, flour, cinnamon, and salt in a small bowl. Using your fingers, mix until no lumps of brown sugar remain. Rub in the butter with your fingertips until it reaches a crumbly state. Refrigerate until ready to use.

Preheat the oven to 375°F and set an oven rack in the middle position. Grease a 9-inch square pan with butter or nonstick cooking spray.

In a medium bowl, whisk together the flour, baking powder and salt. Set aside.

In the bowl of an electric mixer, beat the butter and granulated sugar until creamy, about 2 minutes. Add the eggs one at a time, scraping down the sides of the bowl and beating well after each addition. Beat in the vanilla extract and lemon zest.

Gradually add the flour mixture, alternating with the milk, beating on low speed to combine. Add the berries to the batter and fold gently with a spatula until evenly distributed. Do not over-mix.

Transfer the batter to the prepared pan and spread evenly. Sprinkle the streusel topping evenly over the batter. Bake for 40 to 45 minutes, until golden brown around the edges and a cake tester comes out clean. Let cool in the pan on a rack for about 20 minutes, then serve right from the pan.

This cake is best served on the day it is made. Leftovers will keep well for a few days wrapped in foil and stored at room temperature.

Freezer-Friendly Instructions: The cake can be frozen for up to 3 months. After it is completely cooled, double-wrap it securely with aluminum foil or plastic freezer wrap, or place it in heavy-duty freezer bag. Thaw overnight on the countertop before serving.

Why This Cake Is So Irresistible
The magic of this coffee cake lies in its delightful contrast: a tender, buttery cake studded with juicy blueberries, crowned by an irresistible, crunchy cinnamon streusel. The streusel, made with cold butter and a generous amount of cinnamon, bakes up perfectly crisp and golden. Meanwhile, the cake batter, enriched with softened butter, eggs, vanilla, and bright lemon zest, ensures a wonderfully moist and flavorful base that’s packed with fresh berry goodness.
Prepare for a truly comforting treat. Each bite offers a harmonious blend of textures—the soft, moist cake, the bursts of sweet-tart blueberries, and the satisfying crunch of the spiced streusel. The aroma alone, a warm mix of cinnamon, vanilla, and lemon, promises a delightful experience. This coffee cake feels special enough for a gathering yet simple enough for a weekend morning.
Customization & Variations
While this classic recipe shines as is, you can easily adapt the star ingredient. The recipe specifically notes that frozen blueberries can be used if fresh aren't available—just be sure not to defrost them before adding them to the batter. For an extra bright flavor that beautifully complements the sweet berries and warm spices, don't skip the lemon zest.
This Blueberry Coffee Cake is perfect for any occasion. Serve it warm with a cup of coffee for brunch, alongside tea for an afternoon treat, or as a simple, delightful dessert after dinner. Its impressive height and golden streusel make for a beautiful presentation.
