About Us

Our Story

Marble Jar was founded with one simple goal — to make life’s everyday moments a little more beautiful and a lot more delicious.

What started as a small passion project in Windsor has grown into a proudly independent British brand with a loyal following across the UK. Our first batches were baked in a tiny kitchen with nothing but great ingredients, even greater ambition, and a whole lot of late nights. We believed then — and still do — that food should feel personal, intentional, and made with heart.

So, what’s behind the name Marble Jar? It's inspired by those timeless glass jars that held little treasures in every home — sweets, biscuits, handwritten recipes. To us, it symbolises warmth, nostalgia, and the joy of sharing.

From that idea came everything else: carefully crafted recipes, beautiful packaging, and a customer-first mindset. Today, we deliver our treats nationwide, collaborate with incredible makers, and serve joy one order at a time — all from our kitchen at 1 6, 31 Victoria Street, Windsor.

We’re still independent, still obsessed with quality, and still baking like someone special is coming over.
