Chewy coconut-lime sugar cookies matched around a tangy lime buttercream filling.
The feature to preserve is the shaping: Roll about 27 g, a rounded tablespoon, into each ball and coat in sugar. Place 2 inches apart and bake similar-sized portions together.
Before mixing, measure without packing the flour. Use cooled toasted dry shredded coconut in the dough. Wet fresh coconut changes moisture. Fill completely cooled cookie pairs with a small spoonful of thick lime cream.
Use the observable baking cues as well as the timer. Beat filling butter and confectioners’ sugar smooth, then lime juice, until thick. Spread a teaspoon onto one cooled cookie and top with its matched half.

Instructions
Mixing
- Make the doughCream butter and dough sugar until lighter. Mix in egg, vanilla, lime zest and juice. Add whisked flour, leaveners and salt, then fold in the cooled toasted coconut.
Thermal management
- Prepare for shapingNo scheduled chilling is needed. Start with butter that indents under a finger but remains cool, not greasy; keep dough away from a warm oven.
Shaping
- Shape the batchRoll about 27 g, a rounded tablespoon, into each ball and coat in sugar. Place 2 inches apart and bake similar-sized portions together.
Baking
- Bake to the right texturePreheat to 350°F (175°C). Bake on the center rack for 8–10 minutes. Edges should be set and only lightly colored; centers must lose their wet sheen. Use cool pans for subsequent trays.
Cooling
- Cool before servingRest on the baking sheet for 5 minutes, then move to a rack. Allow about 20 minutes total cooling before storing; the center firms as steam escapes.
Finishing
- Add the finishBeat filling butter and confectioners’ sugar smooth, then lime juice, until thick. Spread a teaspoon onto one cooled cookie and top with its matched half.

Storage & Make-Ahead
| Method | How long | What to do |
|---|---|---|
| Room temperature | Up to 1 day in a cool room | Keep covered; refrigerate promptly if the room is warm. |
| Refrigeration | Up to 4 days | Refrigerate frosted cookies airtight; let only the serving portion soften briefly. |
| Freeze raw | Up to 2 months | Freeze portioned dough balls on a tray, then seal in a freezer bag. Bake from frozen, allowing extra time and checking for a set center. |
| Freeze baked | Up to 2 months | Freeze plain baked cookies up to 2 months; thaw sealed and frost after thawing. |
| Restore | 30–60 minutes | Thaw plain cookies in their sealed container, then finish. Do not oven-warm frosted cookies. |
