Begin by preheating your oven to 350°F (175°C). Prepare a baking sheet by lining it with waxed paper and greasing the surface.
In a mixing bowl, combine flour, sugar, and baking powder. Blend well. Then, incorporate softened butter and an egg into the dry ingredients, mixing until you achieve a smooth consistency.
Add a splash of vanilla extract along with dried lavender to the mixture, stirring gently until everything is well mixed.
Using a tablespoon, drop dollops of cookie dough onto the prepared baking sheet, ensuring they are spaced about 2 inches apart.
Place the baking sheet in the oven and bake for 10 to 15 minutes, or until the cookies emit a delightful aroma and the edges develop a light golden hue.
