Description

This blueberry coffee crumb cake recipe is buttery, moist, and filled with bursts of fresh blueberries. Topped with a golden cinnamon streusel, it’s perfect for brunch, breakfast, or an afternoon snack.


Ingredients

Scale

For the Streusel Topping:

6 tablespoons packed light brown sugar

1/2 cup all-purpose flour, spooned and leveled

1 teaspoon ground cinnamon

1/4 teaspoon salt

4 tablespoons cold unsalted butter, cut into small chunks

For the Cake:

2 cups all-purpose flour, spooned and leveled

2 teaspoons baking powder

1/2 teaspoon salt

1/2 cup unsalted butter, softened

3/4 cup granulated sugar

2 large eggs

1 1/2 teaspoons vanilla extract

1 teaspoon lemon zest

1/2 cup milk

2 cups fresh blueberries (or frozen, unthawed)


Instructions

1. Make the streusel topping by mixing brown sugar, flour, cinnamon, and salt in a bowl. Rub in the cold butter until crumbly. Refrigerate.

2. Preheat oven to 375°F and grease a 9-inch square pan.

3. Whisk flour, baking powder, and salt in a medium bowl.

4. In a separate bowl, beat butter and sugar until creamy.

5. Add eggs one at a time, then beat in vanilla and lemon zest.

6. Gradually mix in the flour mixture, alternating with milk.

7. Fold in the blueberries gently with a spatula.

8. Spread batter evenly in the pan and sprinkle streusel over the top.

9. Bake for 40–45 minutes or until golden and a toothpick comes out clean.

10. Cool in pan for 20 minutes before serving.

Notes

For best results, use fresh blueberries when in season.

Do not defrost frozen blueberries before folding into batter.

Cake tastes best the day it’s made but keeps well for 2–3 days.

To freeze: cool completely, wrap tightly, and store up to 3 months.

Warm slices slightly before serving to refresh the texture.
