Ingredients

Scale

For the Crust:

  • 1 cup shredded unsweetened coconut

  • 1 cup raw walnuts

  • ½ cup Medjool dates, pitted

  • ½ teaspoon sea salt

  • 1 tablespoon coconut oil (optional, for binding if needed)

For the Filling:

  • 2 ripe avocados

  • ½ cup raw cashews (soaked in water for at least 6 hours, then drained)

  • ¼ cup fresh lime juice or key lime juice

  • 1 tablespoon lime zest

  • ¼ cup pure maple syrup (or honey, if not vegan)

  • 1 tablespoon melted coconut oil

  • ½ teaspoon vanilla extract

  • Pinch of sea salt

Optional Toppings:

  • Additional lime zest

  • Coconut flakes

  • Thin lime slices

  • Crushed nuts for texture

Special Tools Recommended:

  • Food processor or high-speed blender

  • Silicone mini muffin tray or non-stick tart molds

Ingredient Preparation:

  • Soak the cashews overnight or in hot water for 1 hour.

  • Soften dates in warm water for 10–15 minutes if they are not soft.

  • Prepare your mini tart molds by lightly greasing or using a silicone tray for easy release.

Instructions

  1. Prepare the Crust
    • Add shredded coconut, walnuts, and sea salt to a food processor.
    • Pulse until the mixture is finely ground but still has texture.
    • Add pitted dates and pulse again until everything sticks together and forms a moist dough.
    • If the dough seems too dry, add a tablespoon of coconut oil to help bind it.
  2. Shape the Tart Bases
    • Divide the crust mixture evenly among 12 mini tart molds or muffin tin cups.
    • Press the crust into the base and up the sides to create a shell.
    • Use your fingers or a spoon to press it firmly so it holds together well.
    • Place the trays in the freezer for 20–30 minutes to firm up while preparing the filling.
  3. Make the Lime Filling
    • In a blender or food processor, combine the following:
      • Avocados
      • Soaked and drained cashews
      • Lime juice
      • Lime zest
      • Maple syrup
      • Melted coconut oil
      • Vanilla extract
      • A pinch of sea salt
    • Blend on high until completely smooth and creamy.
    • Taste and adjust:
      • Add more lime juice for tang
      • Add more syrup if you prefer it sweeter
    • Scrape down the sides and blend again if needed.
  4. Fill the Tart Shells
    • Remove the tart shells from the freezer.
    • Spoon the filling evenly into each shell or pipe it for a more decorative presentation.
    • Smooth the tops with a spatula or the back of a spoon.
  5. Chill Until Set
    • Refrigerate the filled tarts for at least 2 hours until the filling becomes firm.
    • Alternatively, freeze for 30–45 minutes if you’re in a rush.
    • Once set, gently remove the tarts from their molds.
  6. Garnish and Serve
    • Top each tart with your choice of:
      • Lime zest
      • Coconut flakes
      • Lime wedges
      • Crushed pistachios or almonds
    • Serve chilled. These tarts are best enjoyed cold and can be stored in the refrigerator for up to 5 days or frozen for up to 1 month.

Notes

  • Soaking Cashews:
    • Soft cashews blend smoother. If short on time, soak in hot water for 30 minutes.
    • Always drain and rinse soaked cashews before use.
  • Choosing Avocados:
    • Use avocados that are just ripe—not overly soft or stringy inside.
    • Ripe avocados should yield slightly when gently squeezed.
  • On Dates:
    • Medjool dates are ideal for this recipe. If yours are dry, soak them for 10–15 minutes in warm water.
  • Texture Adjustment:
    • If the crust is crumbly, add a bit more coconut oil.
    • If the filling is too thick, add 1–2 teaspoons of lime juice or water to thin it out.
  • Make-Ahead Friendly:
    • Tarts can be made a day or two in advance.
    • Store without garnishes, then decorate just before serving.
  • Nut-Free Version:
    • Substitute sunflower seeds or pumpkin seeds for walnuts in the crust.
    • Use silken tofu or coconut cream instead of cashews in the filling.
