An easy way to frost a cupcake giving it the smooth texture of fondant without the taste is to dip them. To do this, take frosting and warm in microwave for roughly 20 seconds until slightly runny. Add food dye to get your desired color. Dip cupcakes into frosting and allow excess to drip off. This works better if cupcakes have been slightly chilled.

Add sprinkles before frosting dries. I found these fun golden sprinkles at Walmart in the baking aisle.

To make shamrocks, melt chocolate candy melts in a bowl. I found light green key lime green candy melts, which needed a bit more green to be a good shamrock color so I added a wax based food dye from a craft store in the candy making aisle. Or look for candy melts in the color you want. Don’t add regular food dye to your chocolate candy melts, it will ruin your chocolate.

Spoon melted chocolate into a piping bag or ziploc with corner snipped. Place picture of shamrock under wax paper to use as a guide. Pipe chocolate around the edge first, then fill in the middle. Decorate with sprinkles as desired before chocolate dries. Place shamrock toppers in freezer for a minute to harden before placing in top of your shamrock cupcakes.
