These Coconut Lime Bars are the treat I crave when summer heat hits and I want something bright and a little bit tropical. The creamy filling has the perfect blend of zingy lime and sweet coconut with a delightfully tender crust. Great choice when you need a make-ahead dessert that never fails to please a crowd.

When I made these for a backyard barbecue, even my pickiest eater came back for seconds. The fragrance of the lime zest alone promises happiness in every bite.

Lime zest is always my favorite part The smell reminds me of my grandma’s Florida kitchen where she would zest limes straight from her citrus tree My family still fights over the edge pieces with the crispiest coconut topping

Storage Tips

Keep your coconut lime bars chilled in an airtight container in the fridge where they will stay fresh for about one week If you want to prepare them far ahead wrap each square tightly and freeze They thaw quickly in the fridge and taste just as bright as the day they were made

Ingredient Substitutions

Try almond or vanilla extract instead of coconut extract or swap sour cream for plain Greek yogurt If fresh limes are hard to find bottled lime juice works in a pinch although the flavor will be less vibrant For a gluten free crust seek out gluten free graham crackers

Serving Suggestions

For a party platter dust the tops with extra lime zest or a light sprinkle of powdered sugar These bars also pair beautifully with fresh berries or a tangy raspberry sauce If you want an extra tropical vibe scatter a few chunks of pineapple on the side

How to Prepare

Step 01

Preheat oven to 175°C. Line an 20x20 cm or similar-sized baking dish with parchment paper, allowing edges to overhang.

Step 02

In a large mixing bowl, combine crushed graham crackers, all-purpose flour, white sugar, and melted butter. Mix thoroughly until an even, slightly crumbly dough forms. Press mixture firmly into the base of the prepared pan. Bake for 15 minutes until lightly golden.

Step 03

While the crust bakes, whisk sweetened condensed milk, coconut milk, sour cream, lime juice, and lime zest in a clean bowl until silky and well-blended. Incorporate coconut extract and food coloring if desired.

Step 04

Pour filling evenly over the baked crust. Return to the oven and bake for an additional 15 minutes until just set but not browned.

Step 05

Remove pan from oven. While warm, evenly sprinkle shredded coconut over the surface. Cool to room temperature, then chill in the refrigerator for at least 2 hours to allow filling to set.

Step 06

Lift the bars out using parchment overhang. Slice into squares using a sharp knife and serve cold.

Extra Tips

  1. For clean slices, use a hot, damp knife to cut the bars once fully chilled.
