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 lime juice
- Lime green food coloring, or mix of yellow and green to achieve desired color
- 2 tbsp white chocolate, melted (for drizzling)
Instructions
- Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper, allowing some overhang for easy removal, and set aside.
- Cream Butter and Sugar: In a mixing bowl, cream together the softened butter and brown sugar until the mixture is smooth and creamy. This ensures a tender, fluffy base for your bars.
- Add Wet Ingredients: Beat in the egg, vanilla extract, and coconut extract until well combined. This adds moisture and enhances the coconut flavor.
- Fold in Dry Ingredients: In a separate bowl, whisk together the flour, baking powder, and salt. Gradually fold this into the wet mixture along with the shredded coconut until just combined and no streaks of flour remain.
- Add Chocolate Chips and Bake: Gently fold in the mini white chocolate chips. Spread the batter evenly into the prepared baking pan. Bake in the preheated oven for 15-16 minutes or until the edges are lightly golden and a toothpick inserted near the center comes out clean.
- Cool Completely: Remove the pan from the oven and allow the coconut bars to cool completely in the pan on a wire rack. This prevents the frosting from melting when applied.
- Prepare Lime Frosting: In a large bowl, whip together the softened butter, powdered sugar, heavy cream or milk, lime juice, and lime extract until light and fluffy. Add a few drops of lime green food coloring, or a mix of yellow and green, stirring until you achieve the signature frosted coconut bar color.
- Frost and Decorate: Spread the lime frosting evenly over the cooled bars. Drizzle with the melted white chocolate using a piping bag, ziplock bag, or spoon for thicker streaks. Sprinkle additional shredded coconut on top for garnish.
- Chill and Serve: For a firmer frosting, chill the bars in the refrigerator until set. Slice into squares and enjoy with a tall glass of milk or your favorite Starbucks coffee.
Notes
- For an extra coconut flavor, use unsweetened shredded coconut in both the base and as a topping.
- If mini white chocolate chips are unavailable, chop up regular white chocolate into small pieces.
- Room temperature ingredients (butter and egg) help create a smoother batter and frosting.
- Adjust lime juice quantity in frosting to taste, especially if you prefer more or less tang.
- These bars can be stored in an airtight container at room temperature for up to 3 days or refrigerated for up to a week.
- Use parchment paper with overhang to lift the bars from the pan easily after baking.
