Tangy key lime ice cream sandwiched between crisp graham cookies for a refreshing frozen summer treat.

# What You’ll Need:

→ Key Lime Ice Cream

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

→ Graham Cracker Cookies

08 - 1 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 brown sugar, packed
14 - 1 large egg
15 - 1/2 teaspoon vanilla extract

# How To Make:

01 - In a large bowl, vigorously whisk sweetened condensed milk, Greek yogurt, key lime juice, key lime zest, vanilla extract, and a pinch of salt until smooth and fully incorporated.
02 - In a separate chilled bowl, whip heavy cream to stiff peaks using an electric mixer or whisk. Gently fold whipped cream into the lime mixture until homogenous and airy.
03 - Line a 9x9-inch pan with parchment paper. Transfer the lime ice cream mixture to the pan and smooth the surface evenly. Freeze for at least 4 hours until set and firm.
04 - Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper to prevent sticking.
05 - In a medium bowl, combine graham cracker crumbs, all-purpose flour, baking powder, and salt. Stir until evenly distributed.
06 - In a separate large bowl, beat unsalted butter and brown sugar together until light and fluffy. Incorporate the egg and vanilla extract, whisking until smooth.
07 - Gradually add dry mixture to creamed butter mixture, stirring gently until just combined to form a cohesive dough.
08 - Scoop 16 tablespoon-sized portions of dough onto the prepared baking sheet. Flatten each slightly. Bake for 8 to 10 minutes until golden brown at the edges. Cool cookies completely on a wire rack.
09 - Once ice cream is fully frozen, use a round cookie cutter matching the cookie dimensions to cut out 8 ice cream discs.
10 - Place each ice cream disc between two graham cracker cookies, pressing gently to adhere. Serve immediately, or wrap individually and freeze until ready to enjoy.

# Expert Tips:

01 -
  • These sandwiches combine all the flavors of key lime pie in a portable frozen treat you can grab straight from your freezer.
  • Every bite balances tangy citrus and creamy filling with the nostalgic crunch of a graham cracker cookie shell.
02 -
  • If the cookies are still warm when you add the ice cream, you’ll wind up with a melty mess—patience is everything.
  • Cutting out the ice cream only works well if it’s completely frozen through; return it to the freezer if it starts to lose shape while assembling.
03 -
  • Chill your mixing bowls and beaters before whipping cream for the fluffiest texture.
  • Add extra zest to the ice cream base if you love bold citrus flavor—the scent alone is worth it.
