Here are widely recognised gourmet / premium cookie makers and bakeries in Sri Lanka (good starting list if you’re after artisan, gift or premium cookies):

Top artisan / gourmet cookie brands

• Chonk Cookies — NYC-style premium cookies (chunky, soft-centre; offers gift boxes). (chonk.lk)
• CoHo (Coho Cookies) — popular fresh-baked cookies with island delivery and same‑day options in Colombo. (coho.lk)
• Brick Lane Cookie Company — well-known cookie kiosk/shop (Crescat / food‑court presence) with many decadent flavours. (life.lk, ubereats.com)
• Tutu’s Kookies — bespoke / decorated cookies and themed cookie gifts (custom designs). (tutuskookies.com)
• Cape Cookies — small home/Instagram bakery noted for buttery, well‑paired flavours. (life.lk)

Honourable mentions (hotels, bakeries and dessert shops that produce premium cookies)

• The Cakery / English Cake Company — artisan bakery that’s frequently recommended for specialty cookies. (life.lk, tecclk.com)
• Cinnamon Grand (hotel patisserie) — seasonal/premium cookies and gift packs (good for festive/boxed gifts). (life.lk)
• Indulge Desserts Co. and other boutique dessert shops — sell premium cookie lines among other desserts. (nerdynaut.com)

Notes

• If you want strictly “cookie-only” specialists, focus first on Chonk, CoHo, Brick Lane, Tutu’s and Cape Cookies (they’re the most commonly recommended artisan cookie makers online). (chonk.lk, coho.lk, ubereats.com, tutuskookies.com, life.lk)
• Big domestic biscuit manufacturers (Munchee / Ceylon Biscuits, Maliban, Luckyland) make widely available packaged biscuits/cookies but they’re mass‑market rather than artisan/gourmet. (en.wikipedia.org, luckyland.lk)

If you’d like, I can:

• Narrow these to Colombo-only bakeries that deliver the same day, or
• Pick the best options for gifting (packaging/pricing), or
• Suggest specific cookie flavours to try first.
