Key Lime Coconut Pie with Oreo Crust

Key Lime Coconut Pie with Oreo Crust

I enjoy making Key Lime pies when we’re down here in Florida.  I do love chocolate and decided to try an Oreo cookie crust with the lime coconut filling.  I’ve not made an Oreo cookie crust before, in the past when I’m home if I want to have a chocolate crust I have a recipe that I have developed for a Pate Sucrée pastry, but without my food processor I do not make it.


  • 250 ml (1 cup) heavy cream
  • 4 tablespoons icing sugar (sub 2 tbsp sugar)
  • 5-ounces (2/3 cup) unsweetened coconut milk
  • 14-ounces (1 can) sweetened condensed milk
  • 1/4 cup freshly squeezed or bottled Key lime juice
  • Zest of 1 lime, finely grated

To garnish:

  • Whipped cream (optional)
  • Toasted coconut (optional)
  • lime slices (optional)


Bourbon whipped cream idea

  • 1 Cup Heavy Whipping Cream
  • 2 Tablespoons Sugar
  • 1/2 Teaspoon Vanilla
  • 1 teaspoon Bourbon



  • In a bowl, using an electric mixer beat heavy cream and sugar until creamy. Add the coconut milk, condensed milk, lime juice, and lime zest and whisk until fluffy and thick. Pour into crust and refrigerate for at least 30 minutes to set.
  • Before serving, top pie with whipped cream, sprinkle some toasted coconut and/lime slices or lime zest(if desired). Slice and serve.


22 regular Oreo cookies

5 Tablespoons (71g) unsalted butter, melted




  • Make the crust: In a food processor or blender, pulse 22 Oreos (including the cream filling) into a fine crumb. You can also place them in a zip-top bag and crush them into fine crumbs with a little arm muscle and a rolling pin. You should have about 2 cups (packed) crumbs, or 250g. Pour crumbs into a large bowl.
  • Add the melted butter and stir to combine. The mixture will be thick and quite wet. Try to smash/break up any large chunks.
  • Pour the mixture into an ungreased 8-inch, 9-inch, or 10-inch pie dish, cake pan, springform pan, or square pan. With medium pressure using your hand, pat the crumbs down into the bottom and up the sides to make a compact, thick crust. If the mixture seems really wet and is not forming a nice crust, grind up 2 more Oreos and mix those crumbs in. Tip: You can use a small flat-bottomed measuring cup to help press down the bottom crust and smooth out the surface, but do not pack down too hard. If making a pie, run a spoon around the bottom “corner” where the edge and bottom meet to help make a rounded crust⁠—this helps prevent the crust from falling apart when you cut slices.
  • For a baked dessert, pre-bake this crust per your filling recipe directions. I usually pre-bake for 8–10 minutes at 350°F (177°C). For a no-bake filling such as cookies & cream pie, bake for 10–12 minutes at 350°F (177°C). Cool the crust completely before using, unless your no-bake filling recipe instructs otherwise.  Don’t forget to use pie weights to prevent the crust sides from sagging and the bottom from puffing up.


Although we enjoyed the pie, I found the Oreo cookie crust too sweet for me.  I think I’ll go back to making Ritz Cracker crusts when I’m without my food processor.

Thank you Will.  I found that the Oreo cookie crust is a bit too sweet for my tastes, but I still love the coconut lime filling.

Thank you for the suggest Will, if that makes a less sweet crust that would be a good thing.

Happy Baking.
