Mum shared her whacky cake hack online with members of the Woolies/Coles Mudcake Hacks group to celebrate her son finally being toilet trained and was inundated with comments.

“I had promised to make my son a poop cake when he mastered pooping on the toilet! Yipppeee so proud of him. Make with 1x Woolworths white chocolate mud cake and 1x caramel mud cake,” she wrote in her post.

Tamara came up with the idea for the delicious incentive for her four year old Jack after toilet training had stagnated.

“It feels like we have been toilet training our son Jack for far too long,” Tamara tells Yahoo Lifestyle.

“Nappies are expensive and whilst we didn’t want to push too hard to make him use the toilet we encouraged at every moment. It just seemed he would do it when he was ready.

“One of the latest bribes I just came up with was a suggestion of making a huge cake of poop if he finally did the deed,” she said.

Jack seemed to like that idea, so Tamara started searching online for inspiration so that she could be ready if it finally happened. She found the perfect instructional video on YouTube.

To save time, Tamara picked up two Woolworths mud cakes, then made a milk chocolate ganache.

“Whilst it took a few hours to make that night, with a wine or two, the morning cake reveal was the best,” Tamara recalled. “Jack giggled so much and Katie (his 7yr old sister) said it ‘looked amazing and just like poop!’
