SAN ANTONIO – Hot chocolate bombs are all the craze this year. If you can get your hands on a chocolate sphere mold -- they run about $8 to $10 -- then you’re all set. In one half of the sphere add your hot chocolate powder and marshmallows. When you’re ready to enjoy your hot cocoa bomb, warm up some milk in a saucepan and put the cocoa bomb in a mug. When the milk is hot, pour the milk over the chocolate ball in the mug and watch the magic of melting chocolate and marshmallows... enjoy!
