Equipment

  • Mixing Bowl
  • Mixer
  • Spatula
  • Can opener
  • 9”x5” loaf pan
  • Plastic wrap
  • Microplane or Zester
  • Measuring Cups
  • Measuring Spoons

Ingredients

  • 1 can 13.5 oz full-fat coconut milk, chilled overnight
  • 2 cups heavy cream cold
  • 1 tbsp lime zest approx 4 limes
  • 3 tbsp powdered sugar sifted
  • ½ cup lime curd
  • 60 mini thin key lime cookies or 30 regular-sized
  • 4 tbsp unsweetened coconut flakes plus extra for the top layer

Instructions

  • **Make sure you’ve chilled your coconut milk in the fridge overnight before beginning this recipe!**
  • Completely line a 9x5-inch loaf pan with plastic wrap. Leave an overhang to easily lift the cake out later
  • Open the chilled can of coconut milk. The coconut fat should have mostly solidified at the top. Scoop out only the solid coconut fat into a mixing bowl. You might have a little liquid in the bowl, but it shouldn’t be a lot
  • Whip the coconut fat on medium speed until fluffy and smooth, about 3 minutes.
  • Pour in the heavy cream, lime zest, and sift in the powdered sugar. Whip to stiff peaks.
  • To assemble, add a thin layer of whipped cream to the bottom of your pan. Then place a layer of cookies on top, breaking them as needed to completely cover
  • Top with a fourth of your remaining coconut whipped cream
  • Dollop a fourth of your lime curd over the whipped cream and use a knife to swirl it gently throughout the layer. Be careful not to mess up the cookie layer beneath
  • Sprinkle evenly with a tablespoon of your coconut flakes
  • Top with another layer of cookies, repeat these layers, ending with the coconut flakes on top
  • Cover and place in the fridge for at least 10 hours or overnight. This cake needs time for the cookies to absorb the moisture and soften
  • An hour before serving, place your cake in the freezer. This will make it easier to remove from the pan. Then run a warm knife along the edges of the pan before lifting it out using the overhanging plastic wrap
  • Top with extra zest, lime slices, and coconut flakes if desired
  • Slice with a warm knife to ensure clean slices and enjoy!
