Why do my Toll House cookies bake flat? ›

Flat cookies can be the result of a number of issues. Here are some of the main possibilities: OVEN TEMPERATURE: Be sure to have your oven pre-heated and ready to bake. Also be sure that the thermometer is reading correctly.

This baking soda is then able to react with the acidic components of brown sugar, creating gases that cause the cookies to rise up and develop a more open interior structure.

Baking soda is typically used for chewy cookies, while baking powder is generally used for light and airy cookies. Since baking powder is comprised of a number of ingredients (baking soda, cream of tartar, cornstarch, etc.), using it instead of pure baking soda will affect the taste of your cookies.

When to use which one. Baking soda is used in recipes that also include an acidic ingredient, such as cream of tartar, buttermilk, or citrus juice. Conversely, baking powder is typically used when the recipe doesn't feature an acidic ingredient, as the powder already includes the acid needed to produce carbon dioxide.

Baking powder: Baking powder can be used to replace baking soda, though not at a 1-to-1 ratio. Because the former is not as strong as the latter, it's important to use three times the amount of baking powder as baking soda. Be aware, a slightly bitter, off-putting taste might result from using that much baking powder.

Brown sugar, meanwhile, is dense and compacts easily, creating fewer air pockets during creaming—that means that there's less opportunity to entrap gas, creating cookies that rise less and spread more. With less moisture escaping via steam, they also stay moist and chewy.

Brown sugar adds a beautiful color as well as a more complex flavor. They'll also make cookies chewier, softer, and thicker than white sugar. Adding too much can result in dark brown cookies. Adding too little results in paler cookies.

Try using baking powder instead of baking soda. Baking soda encourages spreading while baking powder puffs the cookies up. If your recipe calls for 1 teaspoon of baking soda, you would use 3 to 4 teaspoons of baking powder.

Briefly Freeze Your Cookie Dough Balls

Take your sheet of cookie dough balls and pop it in the freezer while your oven preheats, for about 20 minutes. This will help prevent excess cookie spreading, so you get nice fat thick cookies.

A spread with less fat, diet "margarines" or spreads in tubs contain have too much water. The water creates steam, causing the cookies to puff. Low protein flours, such as cake flour, absorb less water, leaving excess water to create steam, which causes the cookies to puff.
