Remove Oreos from container and set on a paper plate. Set aside another paper plate to use for dipping and decorating the cookies.
Melt chocolate chips using a double boiler (metal or glass bowl over a boiling pot of water). You can also microwave them but be very careful not to burn the chocolate chips.
One at a time, dip the Oreos in the melted chocolate covering both sides. If you don't mind getting messy, use your hands to flip or if you want to be a bit cleaner, use a fork and/or gloves.
Set the chocolate covered Oreos on a paper plate then decorate with your sprinkles! You can enjoy immediately but they will be a bit messy. Placing in the fridge for 30 minutes will help them firm up and be a little less messy.
