For the graham cracker crust

  • 12 graham crackers
  • 1 stick butter melted
  • 1/3 cup brown sugar

For the key lime pie filling

  • 3 egg yolks
  • Zest of 1 lime about 1 Tbsp.
  • 1 can sweet condensed milk 14 oz.
  • 1/2 cup key lime juice
  • Extra creamy whipped cream for topping


  • Preheat the oven to 350 degrees.
  • Place the graham crackers in a large plastic bag and seal. Using a rolling pin (or an empty bottle of wine) roll over the crackers until they are smooth as sand. You can also pulse them in a food processor.
  • Mix together in a large bowl with the brown sugar and melted butter. Make sure the entire mixture is combined.
  • Press the crust mixture into an empty pie pan. To really seal the crust, use the back of a measuring cup and press down the crumbs to pack it into a crust.
  • Bake in the oven for 10 minutes. Remove the crust and let it cool slightly.
  • While the crust is cooling, whisk together the separated egg yolks and the lime zest.
  • Pour in the sweet condesned milk, then the key lime juice. Whisk until combined.
  • Once you're finished preparing the filling, the crust will be ready. Pour in the key lime filling and place it back in the oven.
  • Bake for 17 minutes. The middle will be slightly jiggly when you take it out, do not worry. It will settle.
  • Let it cool completely on a cooling rack (about 30 minutes).
  • Place in the fridge and let it sit for at least 1 hour before eating. Serve with dollops of heavy whipped cream.
