# 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 Steps:
01 - In a large bowl, whisk together sweetened condensed milk, Greek yogurt, key lime juice, lime zest, vanilla extract, and a pinch of salt until smooth.
02 - In a separate chilled bowl, whip heavy cream to stiff peaks. Gently fold the whipped cream into the lime mixture until uniform and creamy.
03 - Line a 9x9-inch pan with parchment paper. Pour the ice cream base into the pan, smooth the surface, and freeze for at least 4 hours or until completely firm.
04 - Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.
05 - In a bowl, combine graham cracker crumbs, all-purpose flour, baking powder, and salt.
06 - In a separate bowl, beat unsalted butter and brown sugar until the mixture is light and fluffy. Add egg and vanilla extract and mix until incorporated.
07 - Gradually mix the dry ingredients into the wet ingredients, stirring until just combined to form the dough.
08 - Scoop 16 tablespoon-sized balls of dough onto the prepared baking sheet. Flatten each slightly and bake for 8 to 10 minutes or until golden. Allow cookies to cool completely.
09 - Once frozen, use a round cookie cutter matching the cookie size to cut out ice cream discs from the pan.
10 - Sandwich each ice cream disc between two graham cracker cookies. Serve immediately or wrap individually and freeze until needed.
# Expert Advice:
01 -
- These sandwiches combine the tartness of key lime with the nostalgic crunch of homemade graham cookies—like summer vacation in dessert form.
- The recipe is surprisingly straightforward and makes you look like a sweets genius at potlucks or picnics.
02 -
- Impatience guaranteed a squishy mess the first time—I learned to freeze the ice cream until truly solid before cutting.
- Trying to skip the parchment made everything much tougher to unmold; now I always line the pan before pouring in the ice cream.
03 -
- Chill your mixing bowl before whipping cream—it comes together faster and overwhips less easily.
- Use a thin, sharp knife run under warm water if a cookie cutter isn’t handy to slice even circles of the frozen ice cream.
