Bake and cool cupcakes and/or 3" circle cookies (sugar cookies or shortbread cookies work great!) Remove your icing decals from the package they arrived in.
If your cupcakes have a rounded top, cut the top off so you have a flat surface.
Apply a generous amount of frosting and smooth it to a flat surface. Any type of soft frosting works well (ex. buttercream, royal icing, or store-bought whipped frosting).
Cookies don't require as much frosting - you can apply a thin, smooth layer.
With clean, dry hands, gently peel the icing decal from the backing sheet.
Place the decal on top of the frosting.
Gently pat it down, smoothing the decal from the center outwards.
Ta da!
If you'd like, you can also add sprinkles or frosting decorations around the edges to finish.
