Ingredients

Bar Base

  • 1/2 cup butter, softened (salted or unsalted)
  • 2/3 cup brown sugar
  • 1 egg, at room temperature
  • 1 tsp vanilla extract
  • 1/4 tsp coconut extract
  • 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 mini white chocolate chips

Lime Frosting

  • 1/2 cup butter, at room temperature
  • 1/2 tsp lime extract
  • 1 1/2 cups powdered sugar
  • 1 tbsp heavy cream or milk
  • 2 tbsp fresh lime juice
  • Lime green food coloring (or mix of yellow and green food coloring)
  • 2 tbsp white chocolate, melted (for drizzling)

Instructions

  1. Preheat and prepare pan: Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper and set it aside to ensure easy removal of bars later.
  2. Cream butter and sugar: In a mixing bowl, cream together the softened butter and brown sugar until the mixture is smooth and creamy to create a rich base.
  3. Add wet ingredients: Beat in the egg, followed by vanilla extract and coconut extract, mixing thoroughly to fully incorporate the flavors.
  4. Combine dry ingredients: Gently fold in the flour, baking powder, salt, and shredded unsweetened coconut just until the flour mixture disappears to avoid overmixing.
  5. Fold in chocolate chips: Incorporate the mini white chocolate chips evenly throughout the batter for sweet bursts in every bite.
  6. Bake the bars: Spread the batter evenly into the prepared baking pan and bake for 15 to 16 minutes until the top is lightly golden and set.
  7. Cool bars: Remove the pan from the oven and allow the coconut bars to cool completely in the pan to set properly before frosting.
  8. Make lime frosting: In a large bowl, whip the softened butter, powdered sugar, heavy cream or milk, lime juice, and lime extract together until the frosting is light and fluffy.
  9. Color the frosting: Add lime green food coloring (or a blend of yellow and green) to the frosting and stir well to achieve the iconic Starbucks lime frosting hue.
  10. Frost the bars: Spread the lime frosting evenly over the cooled coconut bars using a spatula for a smooth top layer.
  11. Decorate: Drizzle the melted white chocolate in thin streaks over the frosted bars using a piping bag, ziplock bag, or spoon, then sprinkle extra shredded coconut on top for texture and visual appeal.
  12. Slice and serve: Cut the bars into squares. Optionally, chill in the refrigerator until the frosting is set for a firmer texture. Serve with a tall glass of milk or your favorite Starbucks coffee for the perfect accompaniment.

Notes

  • Use unsweetened shredded coconut to balance the sweetness and enhance the coconut flavor.
  • Mini white chocolate chips blend better into the batter and distribute more evenly than regular-sized chips.
  • Allow the bars to cool completely before frosting to prevent melting and sliding of the frosting layer.
  • If desired, adjust the lime juice and extract amounts for a more or less tangy frosting.
  • Chilling the bars after frosting helps the frosting to firm up and makes slicing cleaner.
  • Can be stored in an airtight container in the refrigerator for up to 5 days.
