Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
For the Cake:
2 cups all-purpose flour
1 cup granulated sugar
1/2 cup unsalted butter, softened
2 eggs
1 cup sour cream
1 teaspoon vanilla extract
1 teaspoon baking powder
1/2 teaspoon baking soda
1/4 teaspoon salt
1 1/2 cups fresh or frozen blueberries
For the Crumb Topping:
1/2 cup all-purpose flour
1/3 cup brown sugar
1/2 teaspoon cinnamon
1/4 cup unsalted butter, melted
Directions
Preheat the oven to 350°F (175°C) and grease a 9-inch square baking pan to prevent sticking.
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set the mixture aside.
In a large mixing bowl, beat the softened butter and granulated sugar together until the mixture becomes light and fluffy. This step helps create a soft and tender cake texture.
Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract and sour cream until the mixture is smooth and fully combined.
Gradually add the dry ingredients to the wet ingredients, mixing gently until everything is just incorporated. Avoid overmixing to keep the cake soft.
Carefully fold the blueberries into the batter so they are evenly distributed.
Pour the batter into the prepared baking pan and spread it evenly with a spatula.
In a small bowl, combine the flour, brown sugar, cinnamon, and melted butter for the crumb topping. Mix until the mixture becomes crumbly.
Sprinkle the crumb topping evenly over the cake batter.
Bake for 40 to 45 minutes, or until a toothpick inserted in the center comes out clean.
Allow the cake to cool slightly before slicing and serving.

Storage/Reheating
Store leftover blueberry coffee cake in an airtight container at room temperature for up to 2 days. If you prefer longer storage, keep it in the refrigerator where it will stay fresh for up to 5 days.
To reheat, warm individual slices in the microwave for about 15–20 seconds. You can also warm slices in a low oven for a few minutes to restore the cake’s soft texture.
For longer storage, wrap slices tightly and freeze for up to 2 months. Thaw at room temperature before serving.
