I have these pressed paper sticks that are used for candied apples.They are white with the one end that comes to a point, the paper is also smooth or coated. Could they be used as a dowel? Any suggestions.
I would be afraid of the moisture from the cake attacking the paper coating on stick and coming off in the cake.
you can, but they will absorb the moisture and you'll run the risk of them bending and collapsing your cake ( I wouldn't risk it personally)...I've used lollipop sticks and that's what happened with them too
As has been said, they will absorb moisture from the cake.
Now, if the cake is for family; will not travel and only be around for a day or two go ahead , then report back to us
