Preheat the oven to 350°F (175°C).

In a mixing bowl, whisk together the flour, baking powder, and salt.

In another bowl, cream the softened butter and sugar until light and fluffy.

Add the egg and vanilla extract to the butter mixture and mix until combined.

Gradually add the dry ingredients to the wet ingredients, mixing until just combined.

Fold in the edible flower petals gently.

Scoop tablespoon-sized portions of dough onto a baking sheet lined with parchment paper.

Flatten each cookie slightly with the back of a spoon.

Bake in the preheated oven for 10-12 minutes or until the edges are lightly golden.

Allow cookies to cool on the baking sheet for a few minutes before transferring to a wire rack.
