  • Total Time: 35 minutes
  • Yield: 16 servings

Ingredients

Bar Base

  • 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 cup flour
  • 1/2 tsp baking powder
  • 1/4 tsp salt
  • 1/2 cup shredded coconut (unsweetened, plus extra for topping)
  • 1/3 cup white chocolate chips (mini if possible)

Lime Frosting

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

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper, ensuring it extends over the edges for easy removal 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.
  3. Add Wet Ingredients: Add the egg, vanilla bean paste, and coconut flavoring to the butter and sugar mixture. Mix thoroughly to combine all ingredients evenly.
  4. Incorporate Dry Ingredients: Gently fold in the flour, baking powder, salt, and shredded unsweetened coconut just until no flour streaks remain. Then fold in the white chocolate chips evenly throughout the batter.
  5. Bake the Bars: Spread the batter evenly in the prepared baking pan. Bake in the preheated oven for 15-16 minutes or until the edges are lightly golden and a toothpick inserted comes out clean.
  6. Cool Completely: Remove the pan from the oven and let the bars cool completely in the pan on a wire rack before frosting.
  7. Prepare 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, smooth, and fluffy.
  8. Add Color to Frosting: Mix in a few drops of lime green food coloring or combine yellow and green food coloring until you achieve the signature Starbucks lime frosting color. Stir well to distribute evenly.
  9. Frost the Bars: Spread the lime frosting evenly over the cooled bars. Drizzle melted white chocolate over the frosting using a piping bag, ziplock bag, or spoon for a decorative finish.
  10. Final Touch and Serve: Sprinkle additional shredded coconut on top for garnish. Slice into bars and enjoy immediately or chill in the refrigerator until the frosting is set for a cool treat. Serve with milk or your favorite Starbucks coffee for the full experience.

Notes

  • Allow bars to cool completely before frosting to prevent melting and sliding.
  • If you prefer a firmer frosting, refrigerate bars after frosting for 30 minutes.
  • Use unsweetened shredded coconut for best balance of sweetness.
  • Mini white chocolate chips distribute better throughout the batter.
  • Adjust lime juice and flavoring to taste if you prefer a tangier frosting.
  • Parchment paper makes removal and slicing easier.
