Melt the almond bark according to package directions.
Insert a toothpick into each marshmallow.
Dip each marshmallow about halfway (or more!) into the chocolate.
Gently shake to let the excess chocolate drip off the marshmallows, set on wax paper. You can do several and then add sprinkles but don't wait until you are done dipping all the marshmallows or the chocolate will be to hardened.
Allow the marshmallows to finish setting and then store in an airtight container. They will last for several days, don't let them get too warm.
