I love to use a variety of toppings to decorate my cupcakes. If my kids are helping me decorate, I love to put a variety of toppings in small bowls, paper cupcake liners, or even a cupcake pan. Some of the toppings I like to use are crushed cookies, chocolate chips (or any kind of chip), candy, sprinkles, mini marshmallows, and crushed ice cream cones. I also like to put out some healthy options such as nuts, fruit (small berries or chopped fruit works great!), chopped graham crackers, pretzels, or even goldfish crackers. Resealable plastic bags full of different colors of frosting are also fun and easy. Just clip the corner of the bag to use to decorate and just throw it out when you're done so cleanup is a breeze!
I also like to make tall topped cupcakes such as my Green Velvet Dipped Cupcakes. You can use any cupcake recipe. Top the cupcake with frosting, then dip in melted chocolate or candy coating. While the chocolate or candy coating is still warm, decorate with your favorite toppings mentioned above.
