Science: The Key to Crinkly Cookies | Cook's Illustrated? ›

While we found that multiple factors can affect how quickly the top dries out and thus how many cracks are formed (including the temperature of the dough and how rapidly it spreads in the oven), a simple tweak turned out to be key to producing a maximum number of fissures: rolling the balls of dough in granulated sugar ...

The part that makes this a 'crinkle' cookie is the generous coating of powdered sugar that the cookie dough ball gets before going into the oven. As it bakes and spreads on the baking sheet, cracks develop and are exposed, giving the perfect crackle cookie.

Why didn't my chocolate crinkle cookies crack? The most common reason for cookies that don't crack is either that the oven was not hot enough or the baking powder was expired.

Issues with cracking usually derive from the sugar coating, not enough or expired baking powder or baking soda, or the oven temperature isn't hot enough. Solution: Granulated sugar is more effective at drying the surface than powdered sugar.

Fat is a very important ingredient in cookies – it tenderizes, crisps and browns, adds color and a wonderful flavor that is impossible to duplicate.

Most cookies have top crusts that remain relatively soft and flexible as the cookies set during baking. However, if the top surface dries out before the cookie is finished spreading and rising, it hardens, cracks, and pulls apart, producing an attractive crinkly, cracked exterior.

Unlike standard wrinkles, which occur when your skin's natural collagen and elastin production slows down, crinkles are caused by dehydration.

Why are my chocolate crinkle cookies flat? There are generally two reasons why cookies go flat, one is that the butter you used was too soft or downright melted even. The other is that not enough flour was used.

To avoid this, try using as little flour as possible while preparing to roll your dough. Dry – “Dry” or “Crumbly” dough is a product of over-mixing or using too much of any ingredient during the mixing process. This can be reversed by adding one to two tablespoons of liquid (water, milk or softened butter) to your mix.

If the oven is too hot, that can also reduce cookie spread because the outside will set before it has time to spread. Lower temperatures are generally better when it comes to chocolate crinkle cookies to give the dough time to spread.

What happens if you add too much sugar to cookies? ›

Sugar sweetens the cookies and makes them an enticing golden brown. Adding too little sugar can affect the taste and texture of cookies. Adding too much can cause them to be brittle. Take your time creaming the sugar and butter together at the beginning.

Granulated sugar: Derived from either sugarcane or sugar beets, this is the most commonly used sugar in baking, and for good reason. It's neutral in flavor and has medium-sized, uniform crystals that are small enough to dissolve into batters and large enough to create air pockets when creamed with butter.

As the butter melts, the cookie's structure loosens, so that the water in the dough is able to combine with the baking soda, dissolving it. The baking soda then reacts to the acidic components present in brown sugar, creating gases that cause the cookie to rise.

Why are my crinkle cookies not crinkling? If the dough is too wet, then it will dissolve the sugar and the crinkle will get lost. In order for a defined crinkle to form, the surface of the dough needs to be dry. If your cookies are not crinkling then there is too much free water in the dough.

Crispy cookies are actually easier to make. Soft cookies have a water concentration of 6% or higher – moisture being the variable in texture. To make cookies crispy, add less liquid or bake it in the oven for longer to dry out the dough. Generally bake around 13-15min at 180C for a crispy cookie.

The ingredients you use and how you shape your cookies both play an important role in whether your cookies turn out crispy or chewy. The type of flour and sugar you use, if your cookie dough contains eggs, and whether you use melted or softened butter all factor into the crispy-chewy equation, too.
