The arrival of the royal baby has inspired baking businesses to launch seasonal products to mark the birth of the Duke and Duchess of Cambridge’s first child.

Baker Biscuiteers has released a limited-edition royal baby biscuit tin containing 16 assorted biscuits, costing £40, or £43.50 for a personalised tin, plus postage and packing. Stocked in Selfridges, the biscuits come in different iced designs: a silver spoon; teddy bear; booties; a ribbon-wrapped present; a rocking horse; a royal emblazoned baby bottle and bottle of champagne.

Harriet Hastings, Founder, said: "Our Royal Wedding biscuits was one of our top selling collections ever so we were sure that a royal baby collection would be really popular. It’s a lovely souvenir but also perfect for the princes and princesses in everyone’s lives.”

Meanwhile, Scott Ballowner of Kooky Bakes, which has released a range of themed cupcakes, available in Oxford Street’s Selfridges, said he totally underestimated the response the designs would get.

Kooky Bakes has produced two cupcake flavours: a royal red velvet and regal vanilla. The red velvet contains a classic American red velvet sponge, hand-piped cream cheese frosting, blue sprinkles and a handmade baby blue Union Jack baby bib. Regal vanilla contains the bakery’s own bourbon vanilla sponge, hand-piped with baby blue vanilla buttercream, white sprinkles and a handcrafted silver lustred fondant crown. 

Kimberley Card of Sweet Touches, Essex marked the occasion by creating delicate ‘Baby Boy’ blue cupcakes.

“We wanted to mark such a memorable occasion by making a simple yet elegant design for the new royal arrival. It’s a day that will be marked and remembered by everyone.

“All our ingredients are sourced within the UK, and the sponge mixture is a classic Victoria sponge, which to us is even more relevant to a royal occasion.”

The Centre for Retail Research, Nottingham has estimated that the royal birth could generate a £243m boost to the British economy. This is divided between festivities (£87m) and memorabilia (£156m).

Professor Joshua Bamfield, director of Centre for Retail Research, said: “It is no great surprise that this type of feelgood event provides retailers with a welcome boost, with consumer hype generating additional spending. These are difficult times for retailers and every catalyst for consumer spending should be utilised, as this will bring the economic recovery one step closer.”
