When you’re about to begin the decorating process, ensure that your cupcakes are completely cool. This will prevent your buttercream from slipping off each cupcake.
In a medium-sized bowl, use an electric mixer and beat butter, sugar and milk on slow speed. These ingredients will make up your buttercream frosting.
Gradually increase the speed to high and once the ingredients are smooth and form semi-stiff peaks, the buttercream is ready.
Add yellow gel food colouring to the buttercream and mix until completely tinted.
Scoop the buttercream into a frosting bag with Wilton 1M tip attached. Frost each cupcake.
To make Iron Man’s hand: roll 12 spheres out of your red fondant, about ½ an inch in size.
Flatten each sphere, so that it’s about 1 inch in diameter.
To start shaping the hand, use a paring knife to cut out a small triangle from your fondant circle (your circle will look similar to Pac Man).
To proceed, cut slits and give the hand 4 fingers.
Trim the sides to give the hand a more realistic shape. Round out the edges and smoothen any imperfections out.
With your white fondant, roll out 12 spheres, about ¼ of an inch in size.
Pour some edible glitter into a bowl and add a few drops of water. Use a small brush and paint each white sphere with the glitter. Place one sphere on each hand.
Top each cupcake with Iron Man’s hand. Serve and enjoy!
