Ingredients

Graham Cracker Cookies

  • ¾ cup all purpose flour {94g or fluffed, spooned & levelled}
  • ¾ cup graham cracker crumbs {85g}
  • ¼ teaspoon ground cinnamon
  • ¼ teaspoon baking powder
  • ½ teaspoon baking soda
  • ½ cup unsalted butter {113g}
  • ½ cup granulated sugar {100g- plus more for rolling}
  • ½ tsp vanilla
  • 1 egg yolk

Key Lime Cream Cheese Filling:

  • 8 oz cream cheese (softened {light is OK})
  • ½ cup powdered sugar {63g}
  • 1 tablespoon key lime zest
  • 1 tablespoon key lime juice

Instructions

Graham Cracker Cookies

  • Pre-heat oven to 375 F. Line cookie sheets with parchment or silicone baking mats.
  • Cream together butter and sugar. Add the vanilla and egg yolk and blend.
  • In a separate bowl, combine flour, graham cracker crumbs, cinnamon, baking powder and baking soda.
  • Mix the dry ingredients into the wet ingredients. They may not seem to come together right away but keep blending until your dough sticks together {1-2 minutes}.
  • Roll dough into 1-inch sized balls. Roll balls in granulated sugar to coat.
  • Bake for 6-7 minutes, until bottoms of cookies are lightly browned. Cool 5 or so minutes on cookie sheet and transfer to wire rack to cool completely.

Key Lime Cream Cheese Filling:

  • Beat cream cheese with a stand or hand mixer until completely smooth. Add the powdered sugar and mix until completely incorporated.
  • Add the lime juice and zest and mix. Taste and adjust lime if desired.

Assembly:

  • Spread 1 or so tablespoons of cream cheese mixture on the bottom of a cooled cookie. Top with a second cookie.
  • Serve immediately.

Notes

Makes 12 'sandwiches', or 24 total cookies.
Don't assemble cookie sandwiches until just prior to serving.
If you would like to firm up the filling, chill for an hour or so before assembling the sandwiches.
