If there’s one thing I’ve learned from years of Christmas shopping, it’s this: if you see it at M&S and it looks festive, buy it immediately. Every year, their seasonal treats hit the shelves, and every year, they vanish before December even begins. From buttery biscuits to chocolate truffles that feel like luxury in a box, M&S knows exactly how to do Christmas. I’ve rounded up ten of their most-loved festive goodies that always sell out — the ones worth grabbing before they disappear for another year.
M&S Collection All Butter Shortbread Light Up Tin
It’s not Christmas without that famous M&S shortbread tin that literally lights up. Every year, the designs change, but the buttery biscuits inside are always melt-in-your-mouth perfection. The tin doubles as a keepsake (or adorable décor), and they usually sell out by mid-November. At around £10, it’s a beautiful gift — but you’ll want one for yourself too.
M&S Swiss Chocolates Box
These chocolates are the stuff of Christmas legend. Smooth, rich, and beautifully wrapped, they rival luxury brands at half the price. There’s always a queue for them once word gets out, and they’re perfect for hostess gifts or sneaky self-treats. Once you’ve tried them, you’ll understand why people stockpile them for the season.
M&S Collection Mini Colin the Caterpillar Cakes
Colin isn’t just for birthdays — his mini Christmas versions are a festive staple. Each bite-sized sponge is covered in chocolate and topped with holiday sprinkles. They’re fun, nostalgic, and absolutely addictive. They usually disappear from shelves by late November, so if you spot them, grab two boxes. Trust me, one won’t last long.
M&S Collection Chocolate & Orange Panettone
Soft, rich, and scented with orange zest, M&S’s panettone is pure Christmas in bread form. The chocolate version has a loyal fan base for good reason. It’s perfect for breakfast, dessert, or gifting — and it’s one of those products that rarely makes it past the first week of December. Pair it with coffee for the perfect morning treat.
M&S Snowy Christmas Tree Crispies
These adorable rice crispie treats shaped like Christmas trees are a hit with kids and adults alike. They’re light, sweet, and coated with a dusting of icing sugar “snow.” Perfect for festive snack platters or stocking fillers, they usually sell out fast — especially in multipacks. They’re simple, charming, and taste like Christmas nostalgia.
M&S Collection Salted Caramel Truffles
If you only buy one chocolate box this season, make it this one. The silky caramel centre wrapped in smooth milk chocolate is dangerously good. These truffles are often compared to premium chocolatier brands, but they’re a fraction of the price. Every year, they disappear quickly, and every year, I regret not buying more.
M&S Gingerbread Biscuits
Soft, spiced, and perfectly shaped, M&S’s gingerbread is one of those festive staples you can’t skip. They’re ideal for kids’ treats, coffee breaks, or edible gifts. The packaging changes each year, but they sell out every time. They strike that perfect balance between crunchy and chewy — and they smell incredible.
M&S Collection Mince Pies
Of course, the mince pies make the list — they’re practically iconic. Buttery pastry, rich filling, and just the right amount of sweetness make them unbeatable. Whether you prefer the classic or the crumble-topped version, these are always gone by early December. Stock up when you see them; they freeze beautifully too.
M&S Percy Pig Christmas Gummies
The nation’s favourite pig gets a festive makeover every year, and fans go wild for it. Whether it’s Christmas hats or candy cane flavours, these limited-edition Percys always fly off shelves. They’re a fun little gift for stockings or secret Santa swaps — and they sell out faster than you’d think.
M&S Collection Chocolate Yule Log
No Christmas dessert table is complete without this showstopper. Rich chocolate sponge rolled with buttercream and dusted with icing sugar “snow,” it looks as good as it tastes. It’s one of the first things to disappear from M&S’s bakery section each year. Perfect for parties, family gatherings, or those nights when you just fancy something indulgent.
The Takeaway
If you’re planning to fill your cupboards with M&S treats this Christmas, don’t wait until December — by then, it’s too late. These festive favourites have earned cult status for a reason, and once they’re gone, they’re gone. So next time you’re in M&S and spot one of these tins, boxes, or cakes glowing on the shelf, do yourself a favour: grab it before someone else does.
