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

In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy, about 2–3 minutes.

Beat in the egg and vanilla extract until well combined.

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

Gradually add the dry ingredients to the wet mixture, mixing until just combined. Be careful not to overmix!

Divide the cookie dough into separate bowls, depending on how many colors you want to create. Add a few drops of food coloring into each bowl and mix until you achieve your desired color.

Roll the colored doughs into small balls or use cookie cutters to create flower shapes.

Place the cookies on the prepared baking sheets and bake for 10–15 minutes or until the edges are golden.

Allow the cookies to cool before decorating them with royal icing to create flowers or whatever design you fancy.
