Roll a string in brown fondant and cut a few short pieces. Fold them in half.
once they are folden press them together lightly with your fingers. This will be a sideburn. be sure to make one for each ear.
you will have to trim the sideburn to fit properly on the face, the important part is just to have the split at the end to look more like mario.
roll small balls and flatten them in your fingers for the eyes just like you did for the nose. Try and make it thinner though so the eyes don’t look like they are bulging. And for the eyebrows are cut from a string I rolled in black fondant like the sideburns were. Remember use a little water to make it all stick.
For the hat, roll out red fondant and take your cutter you used for the face. DONT CUT WITH IT! just place it on top for a size reference and use and exacto knife above it to cut what looks like a good size hat above it. then you can pick us the cutter and cut the bottom an amount that looks nice to overlap the forhead.
roll another string in red and cut it to be the brim of your hat.
make more balls and flatten them for the irises and the logo on the cap. Then I painted the pupils so I didnt add any bulk to the eyes. you can paint the M on the hat too or roll a string to fold into an M.
I added some shines in the eyes with royal icing but you can choose not to. Then let it sit overnight to dry. Then it will be nice and dry and easy to pick up for placing on cupcakes without damaging it. Just swirl some buttercream and pop her on!
