Nothing says ‘summer vacation’ more than the flavor of key lime pie.  I love the tanginess, the creaminess, and of course the crust.  The crust maybe my favorite part!

I also adore ice cream, popsicles, snowcones….you get the drift.  So, why not combine two favorites into one treat.


  • Lime gelatin
  • Granulated sugar
  • Lemon-lime soda – think Sprite, Fresca, 7-up
  • Sweetened condensed milk
  • Half and Half
  • Key lime juice
  • Graham crackers or graham cracker crumbs


The most difficult part of this recipe is waiting.  You have to wait for the layers to freeze.  If you have patience, then this recipe will be a breeze for you!

  • First, make the ice layer by dissolving the lime gelatin and sugar into the boiling water.  Then stir in the lemon-lime soda and pour the mixture into molds.
  • Then wait for this layer to freeze – about 2 hours.
  • The next step is to make the key lime pie layer by stirring together the sweetened condensed milk, half-and-half, and lime juice and pour it over the frozen lime ice layer.
  • Crumble the graham cracker crumbs on top; stick in the popsicle sticks, and wait for them to freeze – about 2-3 hours.

While using silicone popsicle molds makes this recipe easier and the popsicles familiar-looking, you don’t HAVE to use them. You can use paper cups, muffin tins, ice cube trays, even empty yogurt cups.

Key Lime Pie Popsicles have all the flavors of your favorite pie in a cool, creamy, popsicle that’s perfect for your 4th of July celebration.



For the lime ice layer:

  • 1 cup boiling water
  • 1 package (3-ounces) lime flavor gelatin
  • 2 tablespoons granulated sugar
  • 1 ½ cups cold lemon-lime soda

For the pie layer:

  • 1 can (14-ounce) sweetened condensed milk
  • 1 ½ cups half-and-half cream
  • ½ cup key lime juice
  • 46 whole graham crackers, crushed to a fine crumb


Make the lime ice layer.

In a medium bowl, stir the gelatin mix, sugar, and boiling water together until completely dissolved – about 2 minutes.

Stir in the lemon-lime soda.

Pour the liquid into the bottoms of silicone popsicle molds.  I used 3-ounce molds and used 14 cavities.  The liquid should be about 1-inch in depth.

Freeze until solid – about 2 hours.

Meanwhile, make the pie layer.

In a medium bowl, whisk together the sweetened condensed milk, half-and-half, and lime juice.

Pour the mixture evenly between the popsicle molds with the frozen lime ice, leaving a small amount of room at the top.

Sprinkle some of the graham cracker crumbs on top of each popsicle and gently press into the liquid so that they adhere.

Cover the molds with plastic wrap or the silicone cover and place the popsicle sticks.

Freeze until solid, at least 2 hours.

When frozen solid, peel the mold away from the popsicle and enjoy or wrap in plastic wrap and freeze for up to 1 month.
