Ingredients

  • 1 box key lime cake mix 15.25 oz
  • 2 eggs
  • cup melted butter

Icing (optional)

  • pound confectioners sugar sifted
  • 1 egg white
  • 1 teaspoon lime juice fresh or bottled
  • green food coloring I use paste colors

Instructions

  • Preheat oven to 350F. Line a cookie sheet with parchment paper and set aside.
  • Using an electric mixer, mix the box of cake mix and the eggs. The texture should be like wet sand.
  • Add the melted butter to the egg and cake mix mixture. Combine until smooth. The cookie dough will be very thick and slightly sticky.
  • Let the cookie dough mixture set for 3-5 minutes because that will make it easier to scoop and roll. Scoop cookie dough and roll it in a ball then put it on the prepared cookie sheet.
  • Bake for 8-10 minutes. They will be soft but they will firm up.

Icing and How to Decorate (optional)

  • Add all Icing ingredients except food coloring to a medium bowl and mix with an electric mixer. Mix for 5-8 minutes until the peaks are stiff. Before this, it might be a bit like a glaze.
  • Add about two thirds of icing into a bowl. Add the green food coloring until you think it is a good green color (add a little at a time).
  • Put the white and green icing into two piping bags. if you don’t have a piping bag, use a zip top bag and cut a small hole in the corner (which is what I used).
  • Flip over the cookies (icing the bottom). Pipe icing to cover them with the green icing and shake the cookie until the icing is flat. Work in groups of 3 at a time.
  • Add one dot of white icing in the middle and a circle around the edge of the cookie.
  • On the outside circle, take a toothpick and run the toothpick into the white dot in the middle. This will resemble a cut lime.
  • Allow cookies to set for 1-2 hours to harden and firm up. You can also serve them soft if you prefer.
