Cookie Dough

  • 1/2 cup butter softened
  • 3/4 cup light brown sugar
  • 1/2 cup white sugar
  • 1 large egg
  • 2 teaspoons vanilla
  • 1 Tbsp. milk
  • 3/4 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 1/2 cups all purpose flour
  • 3/4 cups graham cracker crumbs


  • 1/2 cup butter softened
  • 3 cups powdered sugar
  • 1 Tbsp. lime zest
  • 1/4 cup lime juice


  • Preheat oven to 350 degrees. Cover cookie sheets with parchment paper.
  • Cream butter and sugars in the bowl of a stand mixer or mix in large mixing bowl with an electric hand mixer. Mix in egg. Add vanilla and milk.
  • Add dry ingredients.
  • Scoop dough (using a medium cookie scoop) onto parchment paper-lined cookie sheets and bake at 350 degrees for 10 minutes. Let cookies cool for 5 minutes before transferring to wire racks.
  • Beat frosting ingredients together and spread frosting over cookies.
  • Add a small lime wedge to the top of each cookie.
  • Squeeze lime juice over cookies before eating.



  1. I use my stand mixer with the paddle attachment to make cookies, but you can use a hand-held electric mixer as well.
  2. You can use storebought graham cracker crumbs (found in the baking aisle next to graham cracker crumb pie crusts) or place a couple of sleeves of broken graham crackers into a blender of food processor and pulse until finely ground. I’ve done both methods and the cookies turn out the same.
  3. This recipe makes 22 cookies that can be stored at room temperature or chilled in the fridge. Store in an airtight container or cover in plastic.
