Before and during the making of this cake, I searched some clear photos of the minions, I also have the small figures from Mc Donald's happy meal and a stuffed toy beside me. That's just to make sure I get most of the details needed to make it look more like the minion.
Baked on two 6" Springform Pans
Used Wilton Food Color - Lemon Yellow
For the goggles, I cut 16 small circles using an icing tip. I put 8 around each goggle then I sprayed with Wilton color mist.
I cut royal blue fondant with size proportioned to the cake. I embellished by using the small tool tip shown above (in fondant they are used for the leaves) so it will look like it has been sewn.
I just added some details on the goggles' strap to make it look nicer. Also note that the minions have 3 fingers and they wear some kind of school shoes.
For more questions, feel free to comment and I'll get back to you as soon as I can.
