How to Make It
Preheat your oven to 350°F (175°C) and grease a baking dish.
In a large bowl, combine the melted butter and granulated sugar, mixing until well combined.
Add the eggs, lemon juice, and lemon zest, mixing until smooth.
Stir in the flour, baking powder, and salt until just combined.
Gently fold in the blueberries, being careful not to crush them.
Pour the batter into your prepared baking dish and spread evenly.
Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.
While the cake is baking, prepare the glaze by mixing the powdered sugar with lemon juice until smooth.
Once the cake has cooled for a bit, drizzle the glaze over the top.
