La Luciérnaga is a natural pastry business based in Castelldefels, Barcelona, specialising in artisan vegan and gluten-free food. Its recipes are created as vegan and gluten-free from the outset, with an emphasis on real ingredients, organic unrefined flours, local produce and natural sweeteners. The bakery aims to keep sweetness balanced so the flavours of its ingredients can shine, and uses simple packaging designed to be recyclable or compostable.

Customers can order online for collection in the shop or delivery to selected areas, including parts of Barcelona, mainland Spain and the Balearic Islands, depending on the product. Its range includes cakes and other sweet treats, daily gluten-free breads, specialty granolas, seasonal bakes, and gift boxes and baskets. The business also offers pastry workshops for home bakers, professional courses and student placements. Its classes focus on accessible sweet and savoury recipes made without gluten, dairy or eggs. La Luciérnaga shares updates about new products, seasonal offerings and courses, and welcomes enquiries by phone, WhatsApp or email.
