Preheat your oven to 350°F (175°C).

Mix the dry ingredients in a bowl: combine flour, baking powder, and salt until well-blended.

Cream the butter and sugar together until light and fluffy, about 3-5 minutes.

Add the eggs and vanilla extract to the butter mixture and beat until fully incorporated.

Combine the wet and dry ingredients gradually, mixing until just combined.

Chill the dough for at least 30 minutes in the fridge.

Roll out the chilled dough on a floured surface to about ¼-inch thickness and use heart-shaped cutters.

Bake the cookies for 8-10 minutes or until lightly golden around the edges.

Cool the cookies on a wire rack before decorating.

Decorate your cooled cookies with royal icing or fondant in vibrant colors.
