Mix it and Measure it Right

"If you're angry, your cookies aren't going to taste good," Amos told HowStuffWorks.com. Why? Because if you stir your cookie dough with the spirit and vigor of a woman on the verge of a nervous breakdown, your dough will liquefy, and what you want for your dough is body. So don't mix your batter too hard for too long; just blend it until it's smooth and creamy. Add any chocolate chips to the batter last and don't stir them too long, either -- you don't want them to turn your batter brown [source: Amos]

Measure your ingredients with care. If you're new to the kitchen, you might not realize that there are two types of measuring devices -- liquid measuring cups and dry measuring cups. A liquid measuring cup is usually glass or plastic with a handle and a spout. A dry measuring cup is usually metal or plastic with straight edges [source: America's Test Kitchen]. This is important: If you use the wrong type of measuring cup for your ingredients, your measurements will be inaccurate. For example, if you measure your flour in a liquid measuring cup, you're likely to add a whole extra tablespoon to your batter, which, believe it or not, can derail your entire baking project [source: Better Homes and Gardens].
