Dipping your cookies in melted chocolate adds an extra layer of deliciousness. To melt chocolate, go for small, uniformly sized pieces. Chocolate chips are ideal for this. Combine the chips with a 1/4 teaspoon of butter, vegetable oil, or canola oil in a glass bowl. Microwave in 15-second intervals, stirring after each burst. The chocolate should melt evenly after 2-3 rounds. For this, you'll need about 2 ounces or approximately 1/2 cup of chocolate chips.
