# What You'll Need:
→ Key Lime Ice Cream
01 - 1 cup sweetened condensed milk
02 - 1 and 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 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 It:
01 - In a large mixing bowl, combine sweetened condensed milk, Greek yogurt, key lime juice, lime zest, vanilla extract, and a pinch of salt. Whisk until fully blended.
02 - In a separate chilled bowl, beat heavy cream using an electric mixer or whisk until stiff peaks form. Gently fold whipped cream into the lime mixture until homogeneous and smooth.
03 - Line a 9 x 9-inch pan with parchment paper. Pour the combined ice cream mixture into the pan and spread evenly. Freeze for at least 4 hours until firm.
04 - Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.
05 - In a medium bowl, stir together graham cracker crumbs, all-purpose flour, baking powder, and salt until well blended.
06 - In a separate large bowl, beat unsalted butter and brown sugar until light and fluffy. Add egg and vanilla extract, beating until incorporated.
07 - Gradually mix dry ingredients into the wet mixture, stirring just until combined to form dough.
08 - Scoop 16 tablespoon-sized portions onto the prepared baking sheet and flatten each slightly. Bake 8 to 10 minutes until edges are golden brown. Cool cookies completely.
09 - Once ice cream is fully set, use a round cookie cutter matching the cookies’ size to cut out 8 ice cream discs.
10 - Sandwich each ice cream disc between two graham cracker cookies. Serve immediately or individually wrap and freeze until ready to enjoy.
# Expert Tips:
01 -
- If you whisper the words key lime pie and ice cream in the same sentence, people’s eyes light up—it’s like a secret handshake for dessert lovers.
- I never have leftovers, even when I double the batch—friends and family always ask for these by name.
02 -
- Once, I tried skipping parchment in the pan and regretted every sticky, melting second of trying to wiggle the ice cream loose—don't make my mistake.
- The cookies taste best baked just golden on the edges, not brown—overbaking makes them too hard to bite into straight from the freezer.
03 -
- Let the assembled sandwiches sit out for 2-3 minutes before eating—your teeth (and taste buds) will thank you.
- A careful zesting yields all the flavor without bitterness—use the lightest touch on the limes.
