Ingredients

Sugar Cookie

  • 1/2 cup butter
  • 1/2 cup sugar
  • 1 egg white
  • 1 tsp vanilla
  • 1 1/2 cup flour
  • 1 tsp baking powder

Vanilla Butter Cream

  • 1/2 cup butter
  • 3 cups powdered sugar
  • 4 tbsp milk
  • 2 tsp clear vanilla extract
  • candy toppings

Instructions

  • Preheat oven to 350°
  • Cream the butter and sugar together for 2 minutes.
  • Scrape sides of bowl and add egg white and vanilla. Combine thoroughly.
  • Mix in flour and baking powder until completely combined. The texture should be similar to playdoh. If it is too wet, at a little more flour. If it is too dry, at a little water. 1 1/2 cups is always about perfect for me.
  • Roll out onto parchment paper. Use stencil and cut desired number, letter or shape twice.
  • Remove scraps from the parchment paper. 
  • Carefully put the parchment paper (with the cookies on it) onto a cookie sheet. Bake at 350° for 10 -12 minutes. Pull when the center is puffy, no longer glossy and the edges are barely starting to turn color.
  • Cool completely.
  • Cream together all butter cream ingredients. 
  • Pipe large dots onto the cooled cookie. Top with the second cookie and repeat the piping process. 
  • Decorate the top with a variety of candy.
