Ingredients
- 2 cups fresh blueberries
- 2 cups all-purpose flour, divided
- 1 cup sugar, plus 1 tablespoon
- 1 large egg, room temperature
- ½ cup buttermilk
- ½ cup (1 stick) unsalted butter, softened
- 2 tablespoons lemon zest
- 2 teaspoons baking powder
- 1 ½ teaspoons vanilla extract
- 1 teaspoon salt
- ½ teaspoon cinnamon (optional)
Instructions
Step 1: Prepare the Oven and Baking Dish
Preheat your oven to 350°F (175°C). Lightly grease a 9×9-inch baking dish with butter or nonstick spray to prevent sticking.
Step 2: Coat the Blueberries
In a small bowl, toss the fresh blueberries with ¼ cup of flour until coated. This helps prevent them from sinking to the bottom of the cake while baking. Set aside.
Step 3: Cream the Butter and Sugar
In a large mixing bowl or stand mixer, cream together the softened butter, 1 cup of sugar, and lemon zest for 3–5 minutes, or until the mixture is fluffy and lightened in color. This step incorporates air, giving the cake a tender texture.
Step 4: Add the Egg and Vanilla
Beat in the egg until fully incorporated, then stir in the vanilla extract.
Step 5: Mix the Dry Ingredients
In a separate bowl, whisk together the remaining flour, baking powder, salt, and cinnamon (if using).
Step 6: Combine Wet and Dry Ingredients
Alternating between the flour mixture and buttermilk, add both to the batter, beginning and ending with the dry ingredients. Mix until just combined to avoid overworking the batter.
Step 7: Fold in the Blueberries
Gently fold the floured blueberries into the batter. Pour the batter into the prepared baking dish, spreading it evenly. Sprinkle the top with 1 tablespoon of sugar for a subtle crunch.
Step 8: Bake the Cake
Bake for 40–50 minutes, or until a toothpick inserted into the center comes out clean.
Step 9: Cool and Serve
Transfer the cake to a wire rack and let it cool for at least 15 minutes before slicing. Serve warm or at room temperature.
Storage & Reheating
- Room Temperature: Store covered for up to 2 days.
- Refrigerator: Keeps fresh for up to 5 days in an airtight container.
- Freezer: Freeze slices wrapped in foil or plastic for up to 2 months. Thaw overnight before serving.
Pro Tips for Success
- Use fresh blueberries: While frozen can work, they may bleed color into the batter. If using frozen, add them directly from the freezer without thawing.
- Don’t skip the lemon zest: It elevates the flavor and adds freshness.
- Check early: Start checking the cake at 40 minutes, as oven temperatures vary.
- Add extra crunch: Sprinkle coarse sugar on top before baking for a bakery-style finish.
- Make it richer: Swap buttermilk with sour cream or Greek yogurt for extra tang.
Creative Variations
- Blueberry Almond Cake: Add almond extract and top with sliced almonds.
- Blueberry Lemon Glaze: Drizzle with a simple glaze made of powdered sugar and lemon juice.
- Mixed Berry Cake: Substitute half the blueberries with raspberries or blackberries.
- Blueberry Crumble Cake: Add a streusel topping made of butter, flour, and sugar.
- Blueberry Cream Cheese Swirl Cake: Drop spoonfuls of sweetened cream cheese into the batter before baking for a cheesecake-like twist.
Perfect Pairings
- With Coffee: A slice pairs beautifully with a strong cup of black coffee.
- With Tea: Herbal teas like chamomile or fruity teas like berry blends enhance the blueberry flavor.
- With Ice Cream: Serve warm with a scoop of vanilla ice cream for a decadent dessert.
- With Yogurt: Pair with Greek yogurt and honey for a balanced breakfast.
