Ingredients:
For the Cake:
- 2 cups (250g) all-purpose flour
- 1 ½ tsp baking powder
- ½ tsp baking soda
- ¼ tsp salt
- ½ cup (115g) unsalted butter, softened
- 1 cup (200g) granulated sugar
- 2 large eggs
- 1 tbsp lemon zest (from about 1 lemon)
- 2 tbsp fresh lemon juice
- 1 cup (240ml) buttermilk
- 1 ½ cups (200g) fresh blueberries (plus a little flour for dusting)
For the Lemonade Syrup:
- ½ cup (100g) granulated sugar
- ¼ cup (60ml) fresh lemon juice
- 2 tbsp water
For the Lemon Glaze (optional):
- 1 cup (120g) powdered sugar
- 2–3 tbsp fresh lemon juice
Instructions:
- Preheat the oven to 350°F (175°C). Grease and flour a 9-inch (23 cm) round cake pan (or line it with parchment paper).
- Prepare the dry ingredients:
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside. - Cream the butter and sugar:
In a large bowl, beat the softened butter and granulated sugar together until light and fluffy (about 3–4 minutes). - Add eggs and lemon:
Beat in the eggs one at a time, then add the lemon zest and lemon juice. Mix until just combined. - Alternate adding dry ingredients and buttermilk:
Add the dry ingredients in three parts, alternating with the buttermilk. Begin and end with the dry ingredients. Mix until just combined; do not overmix. - Prepare the blueberries:
Toss the blueberries with a tablespoon of flour (this helps prevent them from sinking). Gently fold them into the batter. - Bake:
Pour the batter into the prepared pan and smooth the top. Bake for 35–40 minutes, or until a toothpick inserted into the center comes out clean. - Make the lemonade syrup:
While the cake bakes, combine the sugar, lemon juice, and water in a small saucepan. Heat over medium heat, stirring, until the sugar dissolves. Set aside. - Soak the cake:
As soon as the cake comes out of the oven, poke holes all over the top with a skewer or fork. Slowly pour the lemonade syrup over the warm cake, allowing it to soak in. - Cool:
Let the cake cool completely in the pan, then remove it carefully. - (Optional) Glaze:
If desired, whisk together the powdered sugar and lemon juice to make a glaze. Drizzle over the cooled cake.
Tips:
- For extra blueberry flavor, sprinkle a few extra berries on top before baking.
- You can substitute frozen blueberries if fresh aren’t available — no need to thaw, but dust them with flour before folding into the batter.
