One dad was faced with the ultimate challenge when his daughters asked him for an unusual birthday cake.

When this dad asked his 4-year-old twin girls what sort of cake they’d like for their up-coming birthday, he received an answer he certainly wasn’t expecting.

“My 4-year old twin girls wanted a Hulk Princess cake for their birthday. So I made one!” he wrote on Reddit under his username NobodyLikesASmartAss alongside this image.
