How to melt chocolate for cookies Melting chocolate in the microwave is easy if you go slowly. Always use a glass or ceramic bowl and chocolate that’s not too old. To melt 1/3 cup of melting chocolate I’d begin with 1 minute 15 seconds in the microwave. After that, let chocolate sit for 2-3 minutes. Then, gently stir and see if chocolate begins to melt smooth. If it’s still really solid, add 20 seconds in the microwave, then let it sit again. Often chocolate looks like it’s not melted when it really is, and you don’t know for sure until you gently stir it. If your chocolate melts but it’s too thick to work with, try adding 1/4 teaspoon of coconut oil or shortening, then letting it melt and stirring it in. Where do I buy melting chocolate and edible gold stars? I bought both the red and blue melting chocolate as well as the edible gold stars at our local Michael's store. I've also seen them at JoAnn's and even in the cake decorating section at Walmart. If you find them somewhere else, leave a comment and let me know!
