My daughter was begging me to make some hot cocoa bombs, and we purchased these ao she could make some. Once the chocolate has cooled, these pop out easily since the molds are extremely flexible. Heat up a plate and rub the ring of one mold on the plate. Quickly fill with hot cocoa dry mix and marshmallows (or whatever you want to do) and then heat the other side up and put them together. Press gently but be firm so it stays together. Swipe your finger around the rim to smooth the seam. VOILA! Super easy and fun!
