Melt some chocolate chips in a microwave safe bowl in 30-second intervals until melted and smooth. Stir in between.
On a small plate, pour your sprinkles or nonpareils into an even layer approximately 1/4" deep.
Pour the melted chocolate into a piping bag. (You can just use a sandwich bag - drape it inside a mug so it will be easier to fill. Remove from mug and snip a tiny corner off of the bag.)
Pipe the chocolate into the desired shapes directly onto your plate of sprinkles. (In this case pipe a circle with two smaller circles to resemble a certain mouse that we all love.) Push down slightly so that they will stick to the chocolate.
Place the plate in the freezer for 5-10 minutes until the chocolate is no longer soft.
Gently flip over your decorations and remove from the plate. You can eat them just like candy or add to your favorite dessert - cake, cupcakes, ice cream, strawberry shortcake - the options are endless!
