The best supermarket birthday cakes 2021

What’s not to love about a supermarket birthday cake? We’re talking great cakes at an even greater price point.

Being a parent is a full-time job and we don’t all have the time, or the skills to whip up a cake in the kitchen. Picking up a birthday cake in your weekly shop, in-store or online is a breeze, and honestly, we wouldn’t do it any other way – they’re also especially great if a birthday has slightly slipped your mind, not to worry your local superstore has got you covered.

Supermarkets are your one-stop-shop for birthdays: party food, decorations, presents, balloons and even a delicious birthday cake, you can get it all in one go!

The supermarket birthday cake world is huge, filled with some Twitter drama and plenty of competition, everyone’s looking to give you the best birthday cake possible, so there are plenty of choices out there.

From all-time favourites, like Colin the caterpillar, to cupcake platters and monster cakes, there’s a supermarket birthday cake for every birthday theme.

To show you what the most popular supermarkets have to offer for your next celebration, we've rounded up our favourite supermarket birthday cakes available to buy.
