Ingredients

For the Coconut Bars

  • 1/2 cup butter (softened, salted or unsalted)
  • 2/3 cup brown sugar
  • 1 egg (at room temperature)
  • 1 tsp vanilla bean paste
  • 1/4 tsp coconut flavoring
  • 1 1/4 cups all-purpose flour
  • 1/2 tsp baking powder
  • 1/4 tsp salt
  • 1/2 cup shredded unsweetened coconut (plus extra for topping)
  • 1/3 cup white chocolate chips (mini if possible)

For the Lime Frosting

  • 1/2 cup butter (at room temperature)
  • 1 1/2 cups powdered sugar
  • 1 tbsp heavy cream (or milk)
  • 2 tbsp lime juice
  • 1/2 tsp lime flavoring
  • lime green food coloring (or yellow and green mixed for color)

For Drizzling and Topping

  • 2 tbsp white chocolate (melted, for drizzling)
  • Extra shredded coconut (for sprinkling)

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Line an 8x8 inch baking pan with parchment paper and set aside to prevent sticking.
  2. Cream Butter and Sugar: In a mixing bowl, cream together the softened butter and brown sugar until light and creamy using a hand mixer or stand mixer.
  3. Add Wet Ingredients: Incorporate the egg, vanilla bean paste, and coconut flavoring into the creamed mixture and mix until fully combined.
  4. Combine Dry Ingredients and Fold: Sift together the flour, baking powder, and salt, then fold this dry mixture along with the shredded unsweetened coconut into the wet ingredients until just combined. Avoid overmixing. Fold in the white chocolate chips gently.
  5. Spread and Bake: Spread the batter evenly into the prepared baking pan. Bake in the preheated oven for 15-16 minutes or until the edges turn golden and a toothpick inserted in the center comes out clean.
  6. Cool Bars: Remove the pan from the oven and allow the bars to cool completely in the pan before frosting.
  7. Make Lime Frosting: In a large bowl, whip together the softened butter, powdered sugar, heavy cream (or milk), lime juice, and lime flavoring until the mixture is light, fluffy, and smooth.
  8. Add Color: Add a few drops of lime green food coloring or create a custom shade by mixing yellow and green food coloring. Stir to combine evenly.
  9. Frost the Bars: Once cooled, spread the lime frosting evenly over the coconut bars using a spatula.
  10. Drizzle White Chocolate: Drizzle the melted white chocolate over the frosted bars using a piping bag, a ziplock bag with a corner snipped, or a spoon for thicker streaks.
  11. Finish and Slice: Sprinkle extra shredded coconut over the top for garnish. Slice into 16 squares and serve.
  12. Optional Serving Suggestion: For a chilled version, refrigerate the bars until the frosting sets, and enjoy with a tall glass of milk or your favorite Starbucks coffee.

Notes

  • Use room temperature ingredients for better mixing and texture.
  • If lime flavoring is unavailable, substitute with fresh lime zest for a natural flavor.
  • Use parchment paper to easily lift bars out of the pan.
  • Adjust the amount of shredded coconut in and on top to your preference for texture.
  • White chocolate chips can be replaced with regular or dark chocolate chips if desired.
  • For a dairy-free option, substitute butter and heavy cream with vegan alternatives.
  • Store bars in an airtight container in the refrigerator for up to 5 days.
