The Lidl Cooper cake has been launched by the grocer in the UK as its entrant to the market in response to the caterpillar-shaped celebration cake trend, albeit far later than expected. The cake from the retailer is priced at £6.99 and comes with a complimentary book entitled The Very Late Caterpillar that pokes fun at the brand's addition to the range of celebration cakes on the UK market with a caterpillar profile. This follows on the popularity of the caterpillar-shaped celebration cakes in the UK that are offered by ALDI, Tesco, Sainsbury's Morrisons and Waitrose with the original being created by Marks & Spencer in 1990.
The brand posted about the Lidl Cooper cake on LinkedIn with a touch of humor explaining, "Well, Cooper’s had a busy few years. He hasn’t just been sitting in a box; he’s been living. We’ve actually published a limited-edition book called The Very Late Caterpillar to explain his whereabouts (spoiler: it involves walking London Fashion Week and binge-watching Midgerton)."
