Homemade Key Lime Pie Frozen Yogurt

This Key Lime Pie Frozen Yogurt is a thick, velvety dessert that perfectly captures the essence of the classic Southern pie. By using sweetened condensed milk and full-fat Greek yogurt, we achieve a rich mouthfeel without the need for an ice cream maker. It’s a bright, citrusy treat that balances tart lime with buttery graham cracker crumbs for the ultimate summer snack.

Ingredients Method Notes

Ingredients
  

  • 3 cups full-fat plain Greek yogurt
  • 3/4 cup sweetened condensed milk
  • 1/2 cup fresh lime juice Key limes preferred, regular limes work
  • 1 tablespoon fresh lime zest
  • 1 cup graham cracker crumbs divided
  • 1 teaspoon vanilla extract
  • 1 pinch sea salt

Method
 

  1. Zest the limes before juicing them to ensure you get all the aromatic oils.
  2. In a large mixing bowl, whisk together the Greek yogurt and sweetened condensed milk until smooth.
  3. Add the lime juice, lime zest, vanilla, and salt, whisking until the mixture thickens slightly.
  4. Stir in 3/4 cup of the graham cracker crumbs until evenly distributed.
  5. Pour the mixture into a 9x5 metal loaf pan or a shallow freezer-safe container.
  6. Place in the freezer and stir with a fork every 45 minutes for the first 2 hours to prevent large ice crystals.
  7. Sprinkle the remaining 1/4 cup of graham cracker crumbs on top and press down gently.
  8. Freeze for an additional 2–3 hours or until firm enough to scoop.

Notes

  • Full-fat Greek yogurt is essential; 0% or 2% will result in a much icier, harder texture.
  • If you're using an ice cream maker, follow the manufacturer's instructions after Step 4.
  • For an even more authentic pie taste, try "toasting" your graham cracker crumbs in a pan with a little butter before adding them.
  • Store in an airtight container with plastic wrap pressed directly onto the surface to prevent freezer burn.
