The junior bake off will also include best cake and best decorated cake.
Event organiser Wayne Courtney said: "I am so proud of the success of the Great Roath Bake Off and it's been amazing to watch it grow every year.
Team members made up of volunteers and previous Bake Off winners set up workshops in a local school and we were able to pay for everything so children could come along and learn about baking and cake decorating.
There was an outstanding turnout for last year's Christmas Junior Bake Off with entries from as far away as Swansea coming to Roath.
We started working on the Bake Off in early January and want to put on an event that not just Roath but all of Cardiff can be proud of.

Love Productions behaved in a very un-BBC way towards the Great Roath Bake Off and now it is taking the BBC-ness out of Bake Off altogether.
Bake Off has come a long way since that first series tucked away on BBC2 in 2010.
Conforming to the production guidelines of the BBC rather than the more sensationalist demands of commercial television has made Bake Off what it is - arguably the most quintessentially BBC programme ever.
And as Bake Off moves to Channel 4 it's worth mentioning the latest contribution to the portrayal of elderly women on television.
