Urgent muffin help required!

[Fuzzled]

Help! Looking for urgent help as I really want o make muffins now to show off look good in front of MIL!
I've found a recipe for carrot muffins that is sugar free so suitable for DS.
Recipe makes 10-12 normal muffins, cooks for 10-15 mins at 190 degrees.
DS won't eat a whole muffin but I was given a mini muffin tray which would be ideal for him to eat (contents, not the tray! )
Can anyone advise if I need to reduce cooking time too?

Bit early for baking! I would guess about 6-8 minutes for mini-muffins.

Thanks!
Yes, but early bit have been up since 5!
