Description

Blueberry Lemon Coffee Cake is a soft, bakery-style breakfast cake bursting with juicy blueberries, fresh lemon zest, and a buttery cinnamon streusel topping. Perfect for breakfast, brunch, or dessert, this easy coffee cake is made completely from scratch with simple pantry ingredients.

It bakes beautifully in an 8×8 pan and delivers the perfect balance of tangy citrus, sweet berries, and tender crumb.

Ingredients

Scale

For the Cake

1½ cups all-purpose flour
½ teaspoon baking powder
¼ teaspoon baking soda
¼ teaspoon salt
½ cup unsalted butter, softened
¾ cup granulated sugar
1 large egg
1 teaspoon vanilla extract
1 tablespoon fresh lemon zest
½ cup sour cream
1½ cups blueberries (fresh or frozen, not thawed)

For the Streusel Topping

¼ cup all-purpose flour
¼ cup granulated sugar
½ teaspoon ground cinnamon
2 tablespoons cold butter, cubed

Instructions

Preheat oven to 350°F (175°C). Grease or line an 8×8-inch baking pan.
Make the streusel: combine flour, sugar, and cinnamon. Cut in cold butter until crumbly. Set aside.
In a bowl, whisk flour, baking powder, baking soda, and salt.
Cream butter and sugar until light and fluffy. Add egg, vanilla, and lemon zest.
Alternate adding dry ingredients and sour cream, mixing just until combined.
Gently fold in blueberries.
Spread batter into prepared pan and sprinkle streusel evenly on top.
Bake 40–45 minutes, until a toothpick inserted in the center comes out clean.
Cool 15 minutes before slicing and serving.

Notes

Toss blueberries with a teaspoon of flour to prevent sinking.
Use room-temperature ingredients for best texture.
Do not overmix the batter to keep the cake tender.
Greek yogurt can replace sour cream if needed.
