👩🍳 How to Make Starbucks-Style Coconut Lime Bars
1. Prep Your Pan
Preheat your oven to 350°F (175°C). Line an 8×8-inch pan with parchment paper, leaving overhang on two sides. This makes the bars easier to lift and slice.
2. Make the Blondie Base
Cream butter and brown sugar until fluffy. Beat in the egg, vanilla, and coconut extract. Add flour, baking powder, salt, and shredded coconut. Stir until just combined. Fold in white chocolate chips.
3. Bake the Bars
Spread the batter evenly in your prepared pan. Bake for 15–16 minutes, or until the edges are lightly golden and the center is just set. Let cool completely in the pan before frosting.
4. Whip the Lime Frosting
Beat softened butter until creamy. Slowly add powdered sugar. Mix in lime juice, cream, and lime extract. Beat on high until light and fluffy. Add food coloring one drop at a time to reach a soft green hue.
5. Frost & Garnish
Spread frosting evenly over the cooled bars. Drizzle with melted white chocolate in a zigzag pattern. Sprinkle shredded coconut over top. Chill for 20 minutes to set before slicing.
💡 Tips for Success
- Let the bars cool completely before frosting
- Use unsweetened coconut for better control of sweetness
- Press coconut topping into frosting before chocolate sets
- For clean slices, use a sharp knife warmed under hot water
- Store in an airtight container, layered with parchment
📦 Storage & Make-Ahead Tips
- Fridge: Store frosted bars for up to 5 days in an airtight container
- Freezer: Freeze unfrosted bars up to 3 months; frost after thawing
- Make ahead: Bake and frost a day in advance for best flavor melding
🧁 Variations to Try
- Use key lime juice for a tarter twist
- Swap coconut extract for almond extract (delicious!)
- Add lime zest to both the bars and the frosting
- Try lemon instead of lime for a sunny citrus flavor
🧰 Tools You’ll Need
