Conversation Heart Cocoa Bombs

Aren’t conversation hearts one of the best parts of Valentine’s Day? It’s one of those candies that I wish was in stores year round. Adding them to a white chocolate cocoa bomb has been a lot of fun.

Ingredients You Will Need

  • White Chocolate – for the ball itself and a little extra to drizzle on top.
  • Cocoa Mix – grab your favorite hot chocolate mix or whatever you’ve got at home.
  • Marshmallows – the most important part of any cup of cocoa!
  • Conversation Hearts – for decoration.
  • Gel Food Coloring – we colored ours some fun pastel colors for Valentine’s Day but you could leave these as plain white chocolate if you’d like.
  • Silicone Mold – this is a must for cocoa bomb making.

How To Make A Hot Chocolate Bomb

Once you get the hang of working with melted chocolate these will come really easy to you. The good thing about it, is that no matter how misshapen or messy you first few hot chocolate bombs may look, they all melt exactly the same!

  • Mold the ball. Make the chocolate heart casing by melting white chocolate and coloring it with gel food coloring; spread it inside the silicone molds and refrigerate.
  • Fill. Once the  mold is ready, fill them up with your cocoa, marshmallows and a conversation heart or two.
  • Seal. Seal the top of the heart to the bottom by heating it up on a warm skillet and pressing it to the other half.
  • Decorate. Drizzle white chocolate over the cocoa bomb and add another conversation heart to decorate.
  • Drink. Put your cocoa bomb in a mug, pour hot milk over it and stir.

You can have fun with these and get creative! Pick your favorite colors and your favorite candies to include. Kids really have a blast helping to make these, too. It’s a great time to get them helping out in the kitchen.
