Hot Chocolate Bomb Molds: Insider Tips

To find the best hot chocolate bomb molds, we took a popular recipe and tried out several different silicone molds.

Good news: these molds can be used for more than just hot chocolate bombs—you can make dome cakes, truffles, bath bombs, homemade soaps and more.

The best silicone molds for hot chocolate bombs should be no more than 3″ in diameter—that’s the size of the average mug. (If you get one that is too big, it won’t fit . . . which is the whole point of these wonderful treats!). 

The best size is about 2.25″ wide, in our opinion . . . but 2 to 2.5″ will do.

After trying these molds out, we do have one more tip for hot chocolate bomb crafters: place the mold on a cookie sheet for stability when filling. And fill the mold only three-quarters full if you are making cakes—they will expand when baking.

These silicone molds are handy to have for crafting and cooking. Here are the ones we’d recommend:
