Iced Woofins, iced muffins for dogs made of sponge cake, are now available in Waitrose.

Designed and created for dogs by Michelle Turnbull of Barking Bakery in Preston, Iced Woofins cost £3 a pack. The varieties available are Pink Iced Vanilla Woofin, Vanilla Iced Carob Woofin and Carob Iced Carob Woofin.

Made with dog-friendly ingredients, consisting of a vanilla or carob sponge, Woofins are topped with a swirl of creamy yoghurt icing, and decorated with an assortment of bone-themed biscuits.

Turnbull established Barking Bakery in 2012 when she was searching for unusual dog treats for her dog, Spot.

Kate Gibbs, Waitrose pet buyer, said: "The fun customers can have with pet food is increasing rapidly, as animal-lovers drive demand for quirky ‘humanised’ products, often mirroring mainstream foodie trends.

“The pets love them because they’re delicious, and their owners get a cute cupcake to feed to their dog – it’s a win win.”

The supermarket added that the UK spends £6bn a year on its pets.

A range from Barking Bakery is now available to purchase from selected Pets At Home stores across the UK, including Iced Woofins, a Trio of Mini Woofins and Doggy Popcorn.

In April Harry’s Gourmet Treats, a bakery specialising in luxury dog treats, opened its first site in Portobello, Edinburgh.
