Optional: Use a bread knife to saw the bottom off of the cookies. Snack on the scraps! Lay the cookies on a flat surface. (If you want the doors to stand on their own, cut off the bottoms, but if you're only using them on cupcakes, you can skip this step.)

In a small resealable plastic bag, add candy melts but do not seal.

Microwave at 50% power for 30 seconds and knead with your fingers. Continue to microwave and knead until completely melted.

Seal the bag and snip a small tip into the corner of the bag.

Pipe melted candy onto the cookies to look like doors. 

Add sprinkles and decorations to create fairy doors.

Repeat until you have the desired number of fairy door cookies.

Cut a slit into the center of the cupcake to fit the magical door cookie. Tuck the cookie into the cupcake. 

Color frosting with green food coloring. Place into a pastry bag fitted with tip 233.

Pipe grass frosting onto the cupcakes. Add flower icing decorations.
