Reasons for Flat Snickerdoodles

It can be very frustrating to see your snickerdoodle getting flat after all the hard work that you put into it. The following are the most common mistakes that people make when baking snickerdoodles.

Dough Temperature


The temperature of your dough can affect the texture and fluffiness of the cookies. The chilled dough could also help since it will give everything a bit more time to cook before the fat spreads. This creates a more extraordinary uniform baking of the dough and a fluffier cookie.

Cookie recipes often ask you to kick back the dough earlier than baking. This is an essential step that ought to be no longer ignored—chilling the dough earlier than baking may be the distinction between a flat cookie and a fluffy one.

Note: Add flour if the dough is overly sticky like you have trouble forming a ball with it sticky. Feel free to use a little flour until you get a perfect consistency.


Overmixing Sugar, Butter, and Brown Sugar

It is important to ensure that sugar, butter, and brown sugar mix well but should not overmix at the same time. People find it hard to draw a line between mixing and overmixing. Don’t kill the dough. Just mix enough to incorporate all the ingredients.

Usually, the recipe would say we’ve to mix until the ingredients come up in a creamy texture. So to attain that texture, mixing two or three minutes after the ingredients are incorporated will do just fine.

Even though you’ve mixed your sugar and butter well, still your mixture doesn’t get that Creamy texture?!

That’s probably because of the butter temperature. Many recipes would suggest you use softened butter, so make sure that you don’t use your butter straight out of the fridge. The problem with using the butter straight out of the fridge is that we’ve to mix more to incorporate it with the other ingredients, so eventually leading to overmixing. Taking the butter out of the fridge one or two hours before beginning to bake would do the job just fine.

Sometimes substituting 1/2 of the butter with those butter-flavored Crisco sticks (if the recipe has mentioned 1 cup of butter, use 1/2 cup of butter and 1/2 cup of Crisco) works too.

Note: replacing brown sugar or adding white sugar can also make your Snickerdoodles spread out.


The temperature of the oven


The oven temperature decides whether your Snickerdoodle is going to be a flat one or a fluffy one of puffy one. If the temperature is way too low, then there’s a greater possibility for your Snickerdoodle to end up flat. As the butter will melt, the dough will spread out before the cookies begin to bake, i.e., the baking process is slow.

The other extreme is when the temperature is hot, it’ll create a more puffy Snickerdoodle as every incorporated ingredient will be baked before the cookie can take form.

There is no definite temperature as every oven has different settings and heat properties. Batch testing works to find your perfect temperature.


Expiration date

Always double-check the ingredient’s expiration date as they can affect the consistency and taste and even be unhealthy. Expired rising agents would have lost their power, which will not help the cookies to fluff.


How do I fix my flat Snickerdoodle?

If your first batch came out to be flat out of the oven, try adding one or two tablespoons of flour to the leftover dough and give it a try. Sometimes the problem can also be on your baking sheet, and it would’ve been too hot. Always measure your ingredients precisely. Slightly underbaking the cookies can will make the snickerdoodle soft and chewy. Sifting your flour can make a difference in the softness and fluffiness of the cookie.

Tips: always use the mentioned cream of tartar as it’ll prevent crystallizing the sugar.
