Thin and Crispy Oatmeal Cookies Recipe

Thin and Crispy Oatmeal Cookies.

While many people love thick, chewy oatmeal cookies that may be loaded with raisins, some people prefer crunchier cookies. After all, many love the act of dipping their cookies into a glass of milk or maybe even some hot tea.

Soft, chewy cookies act like a sponge when you dip them and will turn mushy and crumbly fast. Crispy, crunchy cookies like our recipe for Thin and Crispy Oatmeal Cookies are perfect for dipping in whatever beverage you desire.

Oatmeal cookies are the underappreciated cousin in the cookie world to flashier, sweeter, more dramatic cookies like the classic chocolate chip. And yet, recipes like this one are still a welcome addition to a holiday cookie platter. Why is that? It is probably because of the texture of the oats and the buttery richness of the dough. Despite the Oatmeal Cookie’s understated taste and texture, many people will still reach for them at the end of a long day.
These cookies are wholesome, getting their unique texture from the oats that are a healthy proportion of the dough. Oatmeal is more than just a filler ingredient though. The oats in this recipe are loaded with fiber, minerals like manganese, phosphorus, and magnesium, and contain a reasonable amount of protein. According to some nutritionists, oats are one of the most nutrient-dense foods that you can eat. Oats can also lower your blood pressure, leading to increased cardiovascular health and they have anti-inflammatory and anti-itching qualities.
These cookies are made with old-fashioned oats. On your grocery store’s shelves there are generally four options for various kinds of oats. Instant oats are the most processed kind of oats. They will get soft with only the addition of water to the oats. Quick oats are a bit less processed than instant, and they only need a cook time of a few minutes. Do not use quick oats or instant oats for this recipe.
They will not give the cookies the correct texture. Steel cut oats are the least processed of all of the available kinds of oats, and they require a cook time of about 20 minutes. This recipe has not been developed to work with steel cut oats. Old-fashioned oats need to be cooked for ten to fifteen minutes to soften and, because of their long cooking time, they remain firm in the cookies, giving the perfect texture to our Thin and Crispy Oatmeal Cookies.
The major portion of the rich flavor of this recipe comes from the butter. Use the highest quality of butter that you can afford, and do not substitute margarine or shortening in the recipe. The cookies need real butter to have all the delicious flavor that this cookie needs. Additionally, cookies made with real butter spread more and are flatter than shortened-based cookies. For a thin, crisp cookie, butter is the way to go.
