Starbucks Lime Frosted Coconut Bars Recipe: Copycat Guide

After dozens of requests for a copycat version, I picked up the original Starbucks lime bars to test and recreate them at home. The bars were soft and coconut-forward with a bright lime-green frosting. I adjusted the frosting to add a touch more tang so the flavor really pops.

These bars feel summery and tropical — perfect for warm-weather snacking. But because you can make them at home, you don’t have to worry about seasonal availability. Make a batch any time of year.

Frequently asked questions – FAQ

How to store Starbucks lime-frosted coconut bars?

Store the bars in an airtight container at room temperature for up to 4 days if your kitchen is cool. For longer freshness, refrigerate in an airtight container or a zip-top bag for up to 7 days.

Can you freeze lime coconut bars?

Yes. Flash-freeze cut bars on a sheet tray, then layer them with parchment in an airtight container and freeze for up to 3 months. Thaw overnight in the refrigerator or for a few hours at room temperature before serving.

Do I have to use food coloring for the frosting?

No. The green color is purely decorative — the lime flavor comes from the extract and juice. Skip the dye if you prefer.

Is lime extract required?

Lime extract concentrates the flavor but can be hard to find. If you don’t have it, increase the lime juice slightly (reduce milk/cream) to boost the citrus tang.
