- 2 ¼ cups (280g) all-purpose flour
- 1 ½ cups (300g) granulated sugar
- 1 tsp (5g) baking powder
- ½ tsp (3g) baking soda
- ½ tsp (3g) salt
- ¾ cup (170g) unsalted butter, softened
- 3 large eggs, room temperature
- 1 cup (240ml) buttermilk, room temperature
- 2 tbsp (30ml) fresh lemon juice

- 1 ½ cups (225g) fresh blueberries
- 1 cup (120g) powdered sugar
- 2 tbsp (30ml) fresh lemon juice

Instructions:
- Preheat oven to 350°F (175°C). Grease a 9-inch round cake pan or springform pan and line the bottom with parchment paper.
- In a small bowl, toss the fresh blueberries with 1 tablespoon of the measured flour until lightly coated.
- Cream together the softened butter and sugar until the mixture looks pale and fluffy.
- Whisk in the eggs one at a time, followed by the lemon zest and vanilla extract.
- In a separate bowl, sift together the remaining flour, baking powder, baking soda, and salt.
- Alternately add the dry ingredients and the buttermilk/lemon juice mixture to the butter mixture, stirring gently with a spatula until just combined.
- Gently fold in the flour-coated blueberries using a rubber spatula, being careful not to overmix.
- Pour the batter into the pan and smooth the top.
- Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean and the edges begin to pull away from the sides.
- Allow the cake to cool in the pan for 10 minutes before transferring it to a wire rack.
- Whisk together the powdered sugar, lemon juice, and lemon zest until smooth.
- Drizzle the glaze over the top of the cooled cake.
