We've Been Awarded Coeliac UK Accreditation!

Sweet Treats Should Be for Everyone - And At Sponge, They Are

Imagine being at a celebration and the cake you want is off-limits because of gluten intolerance. 

At Sponge, we believe everyone deserves a slice. That’s why we’re beyond excited to announce that our gluten‑free cakes and brownies are now officially Coeliac UK-accredited and feature the trusted Crossed Grain trademark. 

Why Coeliac UK Accreditation Matters

This accreditation isn't just a badge - it's proof of our rigorous standards and our continuous desire to strive for the very best. At our bakery based in Holt, Norfolk, we have: 

• Dedicated bakery space to eliminate cross-contamination

• UKAS‑accredited lab testing for gluten levels (≤ 20 ppm)

• Extensive supplier and ingredient checks

• Regular audits to ensure ongoing compliance

Coeliac UK sets industry-leading criteria - including separate baking environments and strict lab testing - to ensure gluten‑free products are safe and trustworthy.

Baked with Confidence - No Compromises

Our gluten‑free cakes and brownies are:

• Moist and delicious - no dry crumbs here!

• Lovingly crafted with premium, carefully checked ingredients

• Indistinguishable from standard cakes - so everyone will enjoy them

We’ve perfected our recipes and techniques to deliver full flavour without compromise.

What This Means for You

Anyone with coeliac disease or gluten intolerance can now enjoy our treats with complete confidence. We’re now one of the UK’s few bakeries offering one of the widest Coeliac UK‑accredited ranges, featuring flavours like Chocolate Caramel Fudge, Lemon Drizzle, Victoria Sponge and Red Velvet. 

We also introduce seasonal variations that come with gluten-free alternatives, with Strawberries & Cream our latest release that comes in gluten-free - because we don't think you should have to compromise on what you want.

Gluten‑Free Brownies - Deliciously Inclusive

With next‑day delivery across the UK when ordered by 3 pm, they’re ideal for any celebration - from birthdays to thank‑you treats. Choose from classic favourites like Triple Chocolate, or go for our Mixed Gluten-Free Brownie Box, which includes Raspberry & White Chocolate, Salted Caramel, and Hazelnut.

Each box is carefully packaged to fit through standard UK letterboxes, making it easy to send a thoughtful, gluten‑safe surprise.

Gluten-Free Baby Sponge Cakes - Mini Treats, Maximum Joy
