These Best Key Lime Pie Bars offer a tangy and creamy dessert experience with a buttery graham cracker crust, a luscious key lime filling, and a light whipped cream topping. Perfectly balanced between tart and sweet, this no-bake treat is quick to prepare and delightful for any occasion.

Ingredients

Crust:

  • 230g graham crackers (~16 full sheets)
  • ½ cup melted butter (113g)

Key Lime Filling:

  • 2 cans sweetened condensed milk (28oz total)
  • ¾ cup key lime juice (180g)
  • 1 tbsp key lime zest (from 2-3 limes)
  • 2 tsp vanilla extract
  • ⅔ cup sour cream or yogurt (160g)
  • 2 egg yolks

Topping:

  • 1 ½ cups heavy cream, chilled (360g)
  • 2 tbsp granulated sugar

Instructions

  1. Prepare the crust: Crush the graham crackers into fine crumbs using a food processor or by placing them in a sealed bag and crushing with a rolling pin. Mix the crumbs with the melted butter until evenly combined. Press the mixture firmly into the bottom of a lined baking dish to form the crust layer. Refrigerate while preparing the filling.
  2. Make the key lime filling: In a large bowl, whisk together the sweetened condensed milk, key lime juice, key lime zest, vanilla extract, sour cream or yogurt, and egg yolks until smooth and fully combined.
  3. Assemble and chill: Pour the filling over the prepared crust and smooth the surface evenly. Cover with plastic wrap and refrigerate for at least 2 hours or until set firmly.
  4. Prepare the topping: In a chilled bowl, whip the heavy cream with the granulated sugar until stiff peaks form. Spread or pipe the whipped cream evenly over the set key lime filling.
  5. Serve: Slice the bars into squares and serve chilled. Garnish with extra lime zest or thin lime slices if desired for a decorative touch.

Notes

  • Use fresh key lime juice and zest for the most authentic flavor.
  • If key limes are unavailable, substitute with fresh regular lime juice.
  • The bars need sufficient chilling time for the filling to set properly; overnight refrigeration yields best texture.
  • Ensure the heavy cream is well chilled before whipping for better volume.
  • Store the bars in the refrigerator in an airtight container for up to 3 days.
