Bake the cupcakes following the cake mix box or a homemade recipe.
Make the pudding by following the back of the box which is usually just a couple cups of cold milk. Or use homemade vanilla pudding if you wish.
Let the cupcakes cool. Color your white fondant with brown icing color or just use skin-toned fondant. Fondant is usually sold at places like Walmart, Michaels, etc. Or you can certainly order it online. Either way, you will need to knead the fondant until it gets soft enough to roll out.
Roll out the fondant until it is about 1/8th of an inch thick. Then use a round cookie cutter that is roughly the same size as the top of your cupcake and cut out circles of fondant. Next cut out a small hole in the middle of those circles using a cake tip or straw.
Fill up a piping bag with an injector cake tip or normal round tip with the pudding. You may also use a plastic bag instead of a piping bag.
Cut a small cylinder shape of cake out of the middle of the cupcake then pipe in the pudding until it reaches the top.
Frost the whole top of the cupcake and then place down the fondant with the hole right over the hole of the cupcake with the pudding in it. Smooth out the edges of the cupcake.
Paint around the edges of the hole with a thin paintbrush and red food coloring. Then add a chocolate chip as a blackhead.
Place the cupcakes in the fridge for about an hour so the cake and filling and set. This will allow it to pop better. Bring them to a party and have fun popping and eating them! Kinda gross but lots of fun. :)
