Butter contributes milk solids and water to a cookie, both of which soften it. Brown sugar contributes molasses – again, a softener. Using lower-moisture sugar (granulated) and fat (vegetable shortening), plus a longer, slower bake than normal, produces light, crunchy cookies.
Why are my cookies tough? The most common reason that cookies are tough is that the cookie dough was mixed too much. When flour is mixed into the dough, gluten begins to form. Gluten helps hold baked goods together, but too much gluten can lead to tough cookies.
Adding melted butter to your recipe will change your cookies’ and cakes’ structure, density, and texture: Adding melted butter instead of the traditional softened butter will result in a chewier cookie. Softened butter in cookie dough will give you a more cake-like cookie.
How to Make Crispy Cookies. While brown sugar keeps your cookies moist and soft, white sugar and corn syrup will help your cookies spread and crisp in the oven. Using more white sugar in your cookies will result in a crispier end product. To achieve a crispy cookie, skip the rest in the fridge.
Adding chopped nuts stiffens the dough and makes it easier to form. If the dough gets too soft, add a tablespoon or two of flour and mix in well. Cookies made from refrigerated dough can be frozen. Let cool completely and then store in an airtight container.
Store them at room temperature in an air-tight container, like Tupperware. Store different flavors separately. Over time, strongly flavored cookies like molasses or mint will seep into other cookies, so if possible store each flavor in its own container.
