Graham Cracker Crust

  • 1 pack graham crackers about 8-9
  • 2 tbsp brown sugar
  • 7 tbsp melted butter
  • 1/2 tsp cinnamon

Key Lime Filling

  • 4 egg yolks
  • 1 14oz can of sweet and condensed milk I use organic
  • 1/2 cup fresh-squeezed key lime juice
  • 1 tbsp key lime zest

Key lime whipping cream

  • 1 cup heavy whipping cream
  • 1-2 tbsp powdered sugar
  • 1 tsp vanilla extract
  • zest of 1-2 key limes


Graham Cracker Crust

  • Spray a 9x9 pan with cooking spray, and preheat the oven to 325
  • In a food processor or blender, blend up the graham crackers into a fine powder.
  • Pour into a bowl and mix in melted butter, cinnamon, and brown sugar.
  • With your fingers press the crust tightly in the bottom of the pan then bake for 10 minutes. Pull out of the oven and let cool.

Key Lime Filling

  • Separate the eggs and add yolks to a mixing bowl. Whisk or blend well.
  • Whisk in 1 can of sweet and condensed milk.
  • Zest 1 tbsp of lime zest and whisk in.
  • Squeeze 1/2 cup of key lime juice and whisk in.
  • Let this mixture rest on your counter while the pie crust cools completely.
  • Once the pie crust is cool, pour in the filling. Increase the temperature of the oven to 350 and bake for about 20 minutes.
  • Remove from the oven and let cool on the counter, then refrigerate for 2-3 hours before cutting.

Key lime whipped cream

  • In a medium-size bowl mix whipping cream and powdered sugar until stiff peaks are about to form.
  • Add in lime zest and vanilla and continue to whip until thick.
    Make sure not to over whip or it will become lumpy and like butter.
  • Serve on top or on the side of the bars!
