Citrus Slice Cookies
makes 12 to 24 cookies, depending on size
  • For each flavor (I am making 3 batches):
  • ½ pound (2 sticks) unsalted butter, room temperature
  • 3 tsp citrus zest (lemon, lime, orange or grapefruit)
  • 1 cup sugar
  • ½ tsp salt
  • 1 egg yolk
  • 1 egg
  • 2 tsp vanilla extract
  • 2½ cups all-purpose flour
  • For royal icing (this makes enough icing for all 3 batches of cookies):
  • One 2lbs bag of confectioner sugar
  • ⅓ cup meringue powder
  • ¾ cup water
  1. Preheat your oven to 350 degrees F. In the bowl of a standing mixer fitted with the paddle attachment, cream the butter and sugar together at medium speed until light and fluffy. Add egg and mix on low speed until combined. Add citrus zest and vanilla extract and continue mixing until blended. Add flour and mix until combined. Roll out dough to ⅛ thick and cut your cookies using plain circle cutters. Use the appropriate size for each citrus flavor (i.e. smallest for lime and largest for oranges).
  2. Bake cookies for 7 minutes or until the edges start to brown.
  3. To make royal icing, combine all 3 ingredients in the bowl of an electric mixer fitted with the whisk attachment. Mix on low speed for a minute then crank up to high speed and mix for 7 to 14 minutes, depending on size. Divide the icing in 4 and add food coloring to 3 of them (yellow, green and orange).
