Last night The Great British Bake Off featured caterpillar cakes in Party Week of the popular baking show. The technical challenge saw the quarter finalists take on the task of making a caterpillar cake.

The UK’s favourite supermarket[1] couldn’t resist responding to the episode with a series of social posts, including an open letter to Channel 4, which shoppers have found hilarious. It reads:

“To Channel 4, We are intellectual caterpillar counsel to Aldi UK. We write to you regarding Channel 4’s violation of Cuthbert’s rights. Aldi has always been a big fan of the Great British Bake Off, and we’ve long craved a Hollywood handshake… But tonight’s episode really took the biscuit.”

The letter, which is packed full of puns, goes on to say:

“Aldi is prepared to protect its caterpillar and pursue this matter to the fullest extent of the law. We certainly think a legal challenge would be a piece of… well, we think it would be easy. Therefore, we demand that you cease and desist from all further use of, and agree to permanently refrain from, any unlawful reference to, or use of, Cuthbert, including, without limitation, use of the image unless the team crown Aldi Star Bakers for the rest of the series (whilst Paul is dressed as a caterpillar).”

Before being signed off:

“Hopefully this isn’t a case of us trying to have our cake and eat it, and we can avoid a Great British Face Off. Kind regards, Cuthbert’s legal team.”

The post has had shoppers in stitches, with one Facebookusersaying: “This is hilarious. Thank you Aldi for giving me a laugh when I need one.”

While another said: “Watching Aldi UK socials was the only way to watch #GBBO tonight and it didn’t disappoint. Love you guys (and us for the comments).”

A spokesperson at Aldi has confirmed there is no current legal action against Channel 4, but amateur bakers might want to consider buying a caterpillar cake before they attempt to make one at home.

Aldi’s Cuthbert Cake is on sale in stores nationwide for just £5.49 (625g) now.
