Why do blueberries sink in coffee cake?

Blueberries sink because they are heavy and wet, while the batter becomes lighter and expands as it bakes. To solve this issue, toss your berries in a tablespoon of flour before folding them into the batter. This light coating helps the fruit cling to the batter, keeping them suspended evenly throughout the cake.

Can I use frozen blueberries instead of fresh?

Yes, frozen blueberries work beautifully in this recipe. Do not thaw them before adding them to the batter, as this causes their juices to run and turn the cake gray. Simply fold them in straight from the freezer and add a couple of extra minutes to the baking time.

Does coffee cake actually contain coffee?

No, traditional coffee cake does not contain any brewed coffee or espresso. Instead, it gets its name because it is historically designed to be served alongside a hot cup of coffee or tea. The rich, buttery crumb and sweet cinnamon topping are the ideal companions for a warm morning beverage.

What is the best pan to use?

An 8-inch or 9-inch square metal baking pan is the ideal choice for this recipe. Metal pans conduct heat more quickly and evenly than glass dishes, which helps the edges get golden and crisp. If you must use a glass dish, lower the oven temperature by 25 degrees and bake for an extra five minutes.

How do I store it so the streusel topping stays crunchy?

Store the cooled cake in a container with a loose lid, or cover it lightly with a clean paper towel under foil. Airtight containers trap moisture, which will soften the crunchy brown sugar crumbs on top. Keeping a small opening allows steam to escape so the topping remains crisp for up to two days.

Can I substitute the whole milk with a non-dairy option?

Yes, you can easily use almond milk or oat milk as a direct substitute. Choose an unsweetened variety so you do not alter the sugar balance of the cake batter. While non-dairy options work well, whole milk provides the best fat content for a rich, traditional bakery crumb.

Instructions

Prepare oven and pan. Preheat your oven to 350°F and butter a 9 x 9-inch baking dish to prevent sticking.
Mix dry ingredients. Whisk the flour, sugar, baking powder, and salt together in a large bowl to combine.
Add wet ingredients. Stir in the milk, eggs, vanilla, melted butter, and lemon zest until a stiff batter forms.
Fold in berries. Gently fold the fresh blueberries into the batter using a spatula to keep them intact.
Prepare the streusel. Combine brown sugar, flour, cinnamon, and cold butter until the mixture resembles a coarse, pebbly meal.
Bake and cool. Spread the batter into the pan, top with streusel, bake for 40 to 45 minutes, and cool for 15 minutes before serving.

Notes

Toss blueberries in a little flour before folding to prevent them from sinking to the bottom.
Use cold butter when making the streusel to ensure you get those distinct, crunchy crumbs.
Avoid overmixing the batter after adding wet ingredients to keep the cake tender instead of tough.
Do not thaw frozen blueberries if using them, as they can bleed moisture into the batter.
Reheat leftover slices in a toaster oven to restore the crispiness of the cinnamon topping.
