Graham Cracker Cookies

  • 2 1/2 cups (312 g) all purpose flour
  • 1/2 cup (45 g) finely crushed graham crackers
  • 1/2 teaspoon salt
  • 1/2 teaspoon baking powder
  • 1 cup (226 g) unsalted butter, room temperature
  • 1 cup (200 g) dark brown sugar
  • 2 large eggs, room temperature
  • 2 teaspoons vanilla extract
  • 2 tablespoons honey

Key Lime Cream Cheese Frosting

  • 1/4 cup (56 g) unsalted butter
  • 1/2 cup (113 g or 4 oz) package cream cheese
  • 1 tablespoon key lime juice
  • 2 teaspoons key lime zest
  • 2 cups (240 g) powdered sugar


Graham Cracker Cookies

  • In a medium bowl, whisk together the flour, crushed graham crackers, salt and baking powder. Set aside.
  • In the bowl of a stand mixer (or using a hand mixer), beat together the butter and brown sugar on medium speed until light and fluffy, about 2 minutes.
  • Add eggs, one at a time, beating until combined after each addition. Add the vanilla and honey and mixed until incorporated.
  • With the mixer on low speed, slowly add the flour mixture to the bowl. Stir just until incorporated (avoid over mixing).
  • Transfer half the dough onto a piece of plastic wrap and shape into a disc. Wrap in plastic and repeat with remaining dough. Chill the dough in the refrigerator for at least two hours or up to overnight.
  • When ready to bake, preheat oven to 350 F. Line a cookie sheet with parchment paper and set side. Remove dough disc from the refrigerator and remove plastic wrap.
  • Generously flour a work surface and use a floured rolling pin to roll dough to 1/4-inch thickness. Use a 1 1/2-inch circle cookie cutter to cut cookies and place on prepared cookie sheet 1-inch apart. Reroll dough a repeat as necessary.
  • Bake cookies for 6 to 7 minutes or until the edges of the cookies turn golden brown. Cool on the baking sheet for 5 minutes then transfer to a wire rack to cool completely. Prepare key lime frosting while cookies are cooling.

Key Lime Frosting

  • With the mixer on low, slowly add the powdered sugar and mix just until combined.
  • Transfer frosting to a piping bag fitted with a large round tip.


  • Match up two graham cracker cookies that are the same size.
  • Pipe about 1 1/2 teaspoons of frosting on the bottom of one cookie. Place the matching cookie on top. Repeat with remaining cookies and enjoy!
