Instructions

  1. Step 1: Preheat oven to 350°F. In a medium bowl, cream together 1/2 cup softened unsalted butter and 1/2 cup powdered sugar until light and fluffy, about 2 minutes.
  2. Step 2: Stir in 1 1/2 cups all-purpose flour and 1 cup sweetened shredded coconut until the dough forms. Press the mixture evenly into the bottom of an 8x8 inch baking pan lined with parchment paper.
  3. Step 3: Bake the crust for 15-18 minutes until lightly golden around the edges. Remove from oven and set aside.
  4. Step 4: In a separate bowl, whisk together 1 can (14 oz) sweetened condensed milk and 1/3 cup fresh lime juice until smooth and combined.
  5. Step 5: Pour the lime mixture evenly over the warm crust. Return to the oven and bake for an additional 15 minutes until the filling is set but still slightly jiggly in the center.
  6. Step 6: Cool completely in the pan on a wire rack, then refrigerate for at least 2 hours before slicing into bars.

Frequently asked questions

How long does Five-Ingredient Coconut Lime Bars take to make?

Total time is about 48 minutes (15 min prep + 33 min cook). Most home bakers find this fits a weekend afternoon; chill or store as the recipe directs before serving.

How do I store leftover Five-Ingredient Coconut Lime Bars?

Cool fully before storing. Most baked desserts keep at room temperature in an airtight container for 2–3 days, or in the fridge for up to 5 days. Cream- or custard-based desserts must go in the fridge within 2 hours; reheat gently or serve cold per the recipe.

Can I substitute ingredients in Five-Ingredient Coconut Lime Bars?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Five-Ingredient Coconut Lime Bars for a different number of people?

The recipe is written for 16 servings. Multiply each ingredient by (your serving target / 16). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.

American desserts like this pair well with a simple grain (rice, couscous, or crusty bread), a quick salad with acid (lemon vinaigrette, pickled onions), and a pan sauce or yogurt-based dip. Tap "Plan a meal with the AI" to get specific side suggestions.
