Jo Ryan found the chocolate on shelves at Aldi and gave it to her children as part of their Easter egg stash last weekend, ahead of the big day.
But she was 'mortified' when she spotted the sweet treat's...err... phallic shape.
The 44-year-old picked up the £4.99 Moser Roth Chocolate Lovers Duo Egg in milk chocolate and dark chocolate for her children from the Stalybridge branch of Aldi in Greater Manchester on Saturday.
It was only as Jo opened the boxes that she spotted the nine-inch long girthy chocolate treat, giving them out rather sheepishly to her children.
The full-time mum said her oblivious younger children, aged 12 and 13, just complained about the taste of the chocolate, but her 18-year-old daughter shot her 'funny looks'.
Jo shared pictures of the eggs on Facebook to warn others about unusual shape of the egg, with one of her friends replying that the treats looked like they were 'inspired by Ann Summers'.
"The shape of it though," wrote one woman in the comments. "I'm sure I've got something similar in my bedroom drawer."
As another, less subtly, wrote: "It does look [like a] dildo."
Another Facebook user quipped: "What the hell kind of shape is that?"
The mum, from Mossley, Greater Manchester, said: "When I saw the egg I just couldn't believe it.
"I remember looking at it, looking at the box and seeing it read 'lovers duo egg' I just started blushing.
"Even the name's a bit saucy, I don't know what Aldi was thinking.
"When I shared it online straight away people started comparing it to a sex toy.
"When one lady put a comparison picture up I cracked up because they were identical, I swear I had tears running down my face.
"I just thought 'I'm so glad it's not me who's just got a twisted mind'."
She added: "When I showed my eldest the photograph she was rolling around laughing, it was so funny.
"The shape of it and the name of it - when you combine the two - it should have clicked.
"I remember looking at it thinking 'this isn't right, what have I done to my poor children?'
"The younger kids compared them to clogs, thank God."
Aldi declined to comment.
