In a large mixing bowl or an electric mixer, add sugar and softened butter. Mix until combined on medium speed.
Next add egg, baking powder, orange juice, vanilla, and mix. Next, add flour gradually, and mix until the dry ingredients are well combined.
Wrap cookie dough in plastic food wrap and chill dough until firm for 1-2 hours.
On a lightly floured surface, roll out the dough to ¼ thickness using a rolling pin and a pastry mat for easy cleanup.
Use Easter shaped cutter to cut out the cookies from the rolled-out dough. Place on a parchment-lined baking sheet or cookie sheets at least 1-2 inches apart.
Heat oven to 400 degrees, and bake 10-12 minutes until edges are lightly browned.
Cool the cookies completely on their baking tray or a wire rack, and then decorate.
