"It also encourages people to get out and try different ones too," Jordan said.
Emma added, "It's a bit like a hot chocolate trail, like the Christmas lights trail, where people go from one to the other."
The winning cafe will receive a chocolate gift box courtesy of the Kāpiti Chocolate Factory.
The names of cafes taking part will be released closer to the time via the Kāpiti Hot Chocolate Challenge page on Facebook https://www.facebook.com/Kapiti-Hot-Chocolate-Challenge-100813765988131/ .
Interest from cafes, which have free entry into the challenge, has been good with nine onboard so far.
Jordan said, "Sunday Cantina, for example, is taking part and their hot chocolate is entirely plant-based and made in-house.
"Theirs is a really rich hot chocolate.
"In fact, a lot of the entries are plant-based so it seems to be the trend.
"All the businesses involved are excited about it and are using the challenge as team building days too which I think is awesome."
Jordan said the challenge was a good thing to do in the school holidays.
"It's a cool thing, in the cold winter months, to go out and get a hot chocolate indoors but it's also not costing the family a lot of money."
The challenge would happen again next year, if the upcoming challenge was successful, and it was hoped an organisation or business would financially back it.
"It would be cool to grow it.
"This is the first year to see how it goes."
The pair have drawn inspiration from the Hutt City Council and their Hot Chocolate Challenge they fund each year.
