# What You'll Need:

→ Key Lime Ice Cream

01 - 1 cup sweetened condensed milk
02 - 1 and 1/2 cups cold heavy cream
03 - 1/2 cup full-fat Greek yogurt
04 - 1/3 cup freshly squeezed key lime juice
05 - 1 tablespoon key lime zest
06 - 1 teaspoon pure vanilla extract
07 - Pinch of salt

→ Graham Cracker Cookies

08 - 1 and 1/2 cups graham cracker crumbs
09 - 1/2 cup all-purpose flour
10 - 1/2 teaspoon baking powder
11 - 1/4 teaspoon salt
12 - 1/3 cup unsalted butter, room temperature
13 - 1/3 cup packed brown sugar
14 - 1 large egg
15 - 1/2 teaspoon vanilla extract

# How To Make:

01 - In a large mixing bowl, whisk together sweetened condensed milk, Greek yogurt, key lime juice, lime zest, vanilla extract, and salt until fully integrated.
02 - In a separate chilled bowl, whip heavy cream to stiff peaks using an electric mixer or whisk. Gently fold the whipped cream into the lime mixture, incorporating until smooth and uniform.
03 - Line a 9 by 9 inch pan with parchment paper. Pour the lime ice cream mixture into the pan and smooth the surface evenly. Freeze for at least 4 hours, or until fully set.
04 - Preheat oven to 350°F. Line a baking sheet with parchment paper.
05 - In a medium bowl, combine graham cracker crumbs, all-purpose flour, baking powder, and salt, mixing thoroughly.
06 - In a separate bowl, cream together unsalted butter and brown sugar until pale and fluffy. Beat in egg and vanilla extract until homogenous.
07 - Gradually add the dry mixture to the butter mixture, stirring until just combined without overmixing.
08 - Scoop 16 evenly sized tablespoon portions onto the prepared baking sheet and flatten each slightly. Bake for 8 to 10 minutes, or until golden at the edges. Cool cookies completely on a wire rack.
09 - Once the ice cream is firmly set, use a round cookie cutter matching the cookie size to cut 8 ice cream discs.
10 - Sandwich each ice cream disc between two graham cracker cookies. Serve at once, or wrap individually and freeze until ready to enjoy.

# Expert Tips:

01 -
  • The creamy zing of key lime ice cream hugged by homemade graham cracker cookies feels extravagant but comes together with everyday ingredients.
  • These sandwiches hold up in the freezer, meaning you can stash a batch for spontaneous cravings or backyard gatherings.
02 -
  • If you try to assemble before the ice cream is super firm, it turns into a melty mess—patience really pays off.
  • Cutting the ice cream fresh from the freezer gives clean rounds, but running your cutter under hot water first makes this much easier.
03 -
  • Plan to bake the cookies in advance so they&apose fully cool and sturdy for assembling sandwiches.
  • If you want neat edges, press the assembled sandwiches gently in a ring mold before re-freezing.
