To craft these amazing lavender cookies, follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.

2. Cream Butter and Sugar: In a large mixing bowl, beat the softened butter and granulated sugar together until fluffy and pale.

3. Add Egg and Vanilla: Beat in the egg and vanilla extract until fully combined.

4. Combine Dry Ingredients: In another bowl, whisk together the all-purpose flour, baking powder, salt, and finely chopped lavender.

5. Mix Dry Ingredients into Wet Ingredients: Gradually add the dry mixture to the wet ingredients, mixing until just combined.

6. Shape the Cookies: Scoop tablespoon-sized portions of dough and roll them into balls. Place them on the prepared baking sheets, leaving space between them.

7. Flatten the Cookies: Gently press down on each ball to form a disc shape.

8. Bake: Bake in the preheated oven for 15-20 minutes or until the edges are lightly golden.

9. Cool: Allow the cookies to cool on the baking sheets for about 10 minutes before transferring them to a wire rack to cool completely.

10. Dust with Powdered Sugar: Once cooled, dust the cookies with powdered sugar for a beautiful finish.

Following these steps will ensure you create lavender cookies that are not only delicious but also visually stunning.
