Baking these Lemon Blueberry Cookies is straightforward. Follow these easy steps:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C). Line a baking sheet with parchment paper.
2. Cream Butter and Sugar: In a large mixing bowl, cream the softened butter and granulated sugar together until light and fluffy.
3. Add Egg and Flavors: Beat in the egg, lemon zest, lemon juice, and vanilla extract until well combined.
4. Mix Dry Ingredients: In a separate bowl, whisk together the flour, baking powder, and salt.
5. Combine Mixtures: Gradually add the dry mixture to the wet mixture, stirring until just combined.
6. Fold in Blueberries: Gently fold in the blueberries, being careful not to break them.
7. Shape Cookies: Using a spoon or cookie scoop, drop rounded tablespoons of dough onto the prepared baking sheet, spacing them about 2 inches apart.
8. Bake: Place the tray in the oven and bake for 10-12 minutes, or until the edges are lightly golden.
9. Cool: Once baked, remove the cookies from the oven and let them cool on the baking sheet for about 5 minutes before transferring them to a wire rack.
10. Enjoy: Serve warm or allow to cool completely before storing!
