There is no more Catalan night than the Nit de Sant Joan — the eve of 23 June, the summer solstice, when Barcelona spills onto its beaches, rooftops, and plazas for bonfires (fogueres), firecrackers (petards), and cava that flows until sunrise. And at the centre of every gathering sits one thing: the coca de Sant Joan. It's a flat, sweet, brioche-like cake — sometimes studded with candied fruit and pine nuts, sometimes filled with pastry cream — sliced and shared among family and friends as the fireworks begin. To eat coca on this night is to belong.

For celiacs, the coca has always been the cruelest exclusion of the year. It is, structurally, a wheat brioche: enriched dough built on wheat flour, the one thing we can't touch. Year after year, celiac Catalans and visitors have watched the platter go round and reached, instead, for a bowl of pine nuts on their own. The good news for 2026 is that this no longer has to be the night you sit out. In the week before Sant Joan, Barcelona's dedicated 100% gluten-free bakeries bake celiac-safe coca — real coca, with the proper crumb, the candied fruit, the pine nuts — that you can pre-order and carry to the party. Here's where to find one.

1. Gluten Tag! — Gràcia's 100% GF Bakery (Pre-Order Your Coca Here)

Gluten Tag! is a 100% dedicated gluten-free bakery in the heart of Gràcia, with no wheat flour anywhere on the premises — which makes it the single safest place to buy a coca de Sant Joan. Their everyday repertoire runs from sourdough to croissants and cakes, and in the run-up to 23 June they bake seasonal coca de fruita and coca de pinyons on the same dedicated lines. Because cross-contamination simply isn't possible here, you can order without a single follow-up question.

Seasonal coca sells out — ring or message a few days ahead to reserve yours for collection on the 22nd or 23rd. See our gluten-free bakeries guide for the full breakdown of what Gluten Tag! bakes year-round.

2. Glutery — Gràcia's GF Workshop for Coca de Crema

Another Gràcia gem, Glutery runs a 100% gluten-free workshop turning out artisan breads and pastries, and its enriched doughs are some of the best in the city — exactly the skill set a proper coca demands. Their seasonal coca de crema (filled with crema pastissera, Catalan pastry cream) is the one to ask for, alongside a candied-fruit version closer to the classic.

It's a small workshop, so the Sant Joan bake is limited — reserve early. Pair your coca with their everyday pastries; more in our cafés and coffee shops guide.

3. Singluteria — Horta-Guinardó's Custom-Cake Specialist

Singluteria is a fully dedicated 100% GF bakery built around fresh breads, pastries, and — crucially for Sant Joan — custom celebration cakes. That made-to-order muscle means they'll bake a coca to your size and filling: candied fruit, pine nuts, pastry cream, or a mix, sized for a balcony of four or a beach party of twenty.

If you want one coca to feed the whole crew, this is your bakery — give them several days' notice for a large custom order. Great, too, for celiac kids who've never had a slice; see our family-friendly guide.

4. Pastisseria Sense Gluten — Sant Andreu's "Pastry Without Gluten"

The name says it all: Pastisseria Sense Gluten — "pastry without gluten" — is 100% celiac-safe, and its seasonal fruit tarts already have a legendary following. That fruit-forward pastry work translates directly to a beautiful coca de fruita confitada, glossy with candied fruit and scattered with pine nuts, for the Nit de Sant Joan.

A proper pastisseria experience with zero risk — exactly what celiacs rarely get for a festive bake. Worth the trip out to Sant Andreu; reserve ahead for the 23rd.

5. El Noi del Pa Sense Gluten — Horta-Guinardó's Artisan Bread Bakery

"The Boy of Gluten-Free Bread," El Noi del Pa Sense Gluten, is a 100% dedicated artisan bread bakery — rustic loaves, baguettes, focaccia. That command of enriched, well-structured dough is precisely what separates a good coca from a dense one, and their coca de pinyons (the pine-nut-and-sugar classic) reflects it.

A favourite of celiac locals who care about texture above all. Order a couple of days ahead and ask what they're baking for the verbena this year.

6. Sana Locura — Sant Gervasi (Coca Plus a Sit-Down Slice)

Sana Locura is part bakery, part restaurant in Sant Gervasi, baking some of Barcelona's best GF bread with a croissant that has a loyal following. The kitchen-and-bakery combination makes it the rare spot where you can buy a whole coca to take to the party and also sit down for a slice with coffee in the days around Sant Joan.

Handy if you're easing into the celebration earlier in the day. See our brunch and breakfast guide for more from this part of town.

7. GEA The Healthy Bakery — Poble Sec's Organic Take

GEA The Healthy Bakery in Poble Sec combines organic, healthy ingredients with certified GF baking — its muffins and banana bread are excellent. For Sant Joan, expect a lighter, less-sugary coca in keeping with the bakery's wholefood leaning: a good choice if you want the ritual without the sugar crash before a long night out.

Central and easy to fold into a day on Montjuïc. Pair it with a scoop afterwards from our gluten-free ice cream guide.

What Exactly Is a Coca de Sant Joan?

If you're new to Catalonia, here's why this cake matters so much. The coca is an oval, flattish enriched bread — closer to a French brioche or an Italian focaccia dolce than to a sponge cake — eaten across the Catalan-speaking world for festivals. The Sant Joan version is the most famous of all, and it comes in several guises:

• Coca de fruita (confitada): the postcard classic, topped with glossy candied fruit — cherries, melon, orange — and pine nuts.
• Coca de pinyons: simpler and, for many, the best — just pine nuts and sugar pressed into the dough.
• Coca de crema: filled or topped with crema pastissera (Catalan pastry cream), often with a caramelised top.
• Coca de llardons: the savoury-sweet one studded with pork crackling — more associated with Carnival, but it appears at Sant Joan too.

It's traditionally eaten on the Nit de Sant Joan (the night of 23 June) with a glass of cava, outdoors, while the city sets off fireworks for the solstice. Sharing it is the whole point.

Why the Traditional Coca Is Off-Limits for Celiacs

Understanding what's in a coca helps you ask the right questions — and explains why "just pick off the topping" doesn't work:

• The dough is wheat through and through: a coca is an enriched wheat-flour brioche. There's no gluten-free part to salvage — the cake itself is the problem.
• Pastry cream is usually thickened with flour: traditional crema pastissera is set with wheat flour or a mix of flour and cornflour, so even the filling can carry gluten.
• The bakery is a wheat-flour environment: a normal pastisseria bakes coca beside croissants and ensaïmades all morning — airborne flour and shared surfaces make a "GF coca" baked there unsafe. This is exactly why a 100% dedicated GF bakery is the only reliable answer.
• The toppings are mostly fine: candied fruit and pine nuts are naturally gluten-free — the danger is the dough and the cream, not the decoration.

How to Order a Gluten-Free Coca in Time for Sant Joan

Seasonal coca is a pre-order item, not something you'll reliably grab off the shelf on the 23rd. A little planning makes the difference:

• Reserve several days ahead: dedicated GF bakeries bake limited Sant Joan batches and they sell out. Call or message early in the week of 23 June.
• Say it clearly: "Voldria encarregar una coca de Sant Joan sense gluten per al dia 23." (I'd like to order a gluten-free coca de Sant Joan for the 23rd.)
• Choose your variety: de fruita (candied fruit), de pinyons (pine nuts), or de crema (pastry cream) — confirm the cream is made with GF starch.
• Default to 100% dedicated bakeries: for a festive bake, never rely on a conventional pastisseria's "GF option." Stick to the fully gluten-free bakeries in this guide where cross-contamination simply can't happen.
• Pick a cava to match: Spanish cava is naturally gluten-free — see our wine bars and bodegas guide for celiac-safe bottles to bring to the verbena.

This Year, Reach for the Platter

For as long as most celiacs can remember, the Nit de Sant Joan has come with a small, specific sadness: the coca goes round, everyone takes a slice, and you quietly don't. In 2026, that ends. Between Barcelona's dedicated gluten-free bakeries and a few days' notice, you can carry a real coca de Sant Joan — proper crumb, candied fruit, pine nuts and all — down to the beach or up to the rooftop, pour the cava, and take your slice with everyone else as the first fireworks go off. Bona revetlla! (Happy Sant Joan's eve.)
