You can use several methods to melt chocolate chips to drizzle over cookies. These methods utilize the stove top, the oven, and the microwave oven. All three methods have one thing in common: Melt the chocolate chips slowly over a low heat. If you try to melt chocolate more rapidly, over a higher heat, it will become grainy and have a burnt flavor. It will also become grainy if any water gets into it, so ensure that no water gets into the pan or bowl with your chocolate.
Things You'll Need
Ceramic mixing bowl
Metal mixing bowl
Place an inch of water in the bottom of the double boiler. Put the chocolate chips in the top of the double boiler.
Cook over low heat. Stir occasionally with a wooden spoon. Don't use a metal spoon because it will absorb part of the heat.
Remove from the heat as soon as the chocolate is melted. Stir until smooth.
Preheat the oven to 110 degrees F. If your oven does not go that low, set it at the lowest setting and leave the door ajar.
Put chocolate chips in a metal mixing bowl. Place in the oven for approximately one hour.
Remove from the oven as soon as the chocolate is melted. Stir until smooth.
Place chocolate chips in a microwave-safe bowl. Place in the microwave.
Cook 6 oz. milk chocolate chips on medium-high power for one minute. Stir. Microwave for an additional 10 seconds; repeat as necessary, stirring in between. Remove when melted. Semi-sweet chocolate chips follow the same procedure with the microwave on high.
Remove as soon as the chocolate is melted. Stir until completely smooth.
Use a larger pan with a smaller pan suspended inside of it in place of a double boiler if you do not have access to one.
