Ingredients
For the Cake:
- 1 ½ cups all-purpose flour
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ¼ teaspoon salt
- ½ cup unsalted butter (softened)
- ¾ cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 teaspoon lemon zest
- ½ cup sour cream (or Greek yogurt)
- 1 ½ cups fresh or frozen blueberries (tossed in 1 tablespoon flour)
For the Crumble Topping:
- ½ cup all-purpose flour
- ½ cup brown sugar
- ½ teaspoon cinnamon
- ¼ cup chopped nuts (optional – walnuts, pecans, or almonds)
- ¼ cup unsalted butter (cold, cubed)
For the Optional Glaze:
- ½ cup powdered sugar
- 1–2 tablespoons milk or lemon juice
Step-by-Step Instructions
Step 1: Preheat & Prep
Preheat your oven to 350°F (175°C). Grease and line an 8-inch round or square baking pan.
Step 2: Make the Crumble Topping
In a small bowl, combine flour, brown sugar, cinnamon, and nuts. Cut in the cold butter with a fork or your fingers until the mixture resembles coarse crumbs. Set aside.
Step 3: Mix the Cake Batter
In a medium bowl, whisk flour, baking powder, baking soda, and salt.
In a separate large bowl, cream butter and sugar until light and fluffy. Add eggs, one at a time, then stir in vanilla and lemon zest. Mix in sour cream until smooth.
Gradually add the dry ingredients to the wet mixture until just combined.
Step 4: Add the Blueberries
Toss the blueberries with a little flour (this prevents sinking). Gently fold them into the batter.
Step 5: Assemble the Cake
Spread the batter evenly in the prepared pan. Sprinkle the crumble topping generously over the top.
Step 6: Bake
Bake for 40–45 minutes, or until a toothpick inserted into the center comes out clean.
Step 7: Cool & Glaze
Let the cake cool in the pan for 10 minutes, then transfer to a wire rack. If desired, whisk together powdered sugar and milk (or lemon juice) and drizzle over the cooled cake for an extra touch of sweetness.
