How To Make Oatmeal Cookies

Because these easy oatmeal cookies are so simple, I usually make them at least once a month. I can’t help it; they are my latest addiction! Here are the simple steps to making your own oatmeal cookies. 

First Step: Add the whole rolled oats to your food processor and pulse for 10-12 times. It should look like a mixture of chopped oats and some oat flour. 

Second Step: Place the chopped oats in a medium-sized bowl. Pour in the baking soda, flour, salt, cinnamon, and nutmeg into the oats and whisk. Set aside. 

Third Step: Put the brown sugar, white sugar, and unsalted butter into a bowl and begin beating on medium-high speed. It will take around 2 minutes to make it creamy and soft. 

Fourth Step: Turn up the speed on the mixer to high and mix in the eggs, molasses, and vanilla until combined. Scrape down the sides of the bowl as needed. 

Fifth Step: While mixing at low speed, slowly add the flour mixture to the wet ingredients. Mix until everything has been combined well. 

NOTE: The oatmeal cookie dough is going to be thick and sticky. This is completely normal. 

Sixth Step: Using plastic wrap or a towel, cover the cookie dough, and put in the refrigerator for 45 minutes all the way up to 4 days. 

Seventh Step: When you are ready to bake the cookies, preheat the oven to 350 degrees F. Then prepare the cookie sheets with parchment paper and set aside. 

Eighth Step: Use a small cookie scoop and place cookie dough balls on the baking sheet leaving 3 inches in between each cookie. 

Ninth Step: Bake the easy oatmeal cookies for 11-12 minutes, then place the cookie sheet on a wire rack to cool for a few minutes. Then remove the cookies from the pan and let them finish cooling them to the wire rack to cool all the way. 

Tenth Step: While the cookies are baking, begin making the icing. Sift the powdered sugar into a bowl, then add the vanilla and 1 tablespoon of milk. Combine the ingredients with a fork. Add 1 tablespoon of milk at a time until it reaches the consistency you like. The icing is supposed to be pretty thick. 

Eleventh Step: Take one cookie at a time and lightly dip it into the icing. You only want to ice the tops of the cookies.

Iced Oatmeal Cookies Variations

Guess what! You can adjust the ingredients in these homemade oatmeal cookies, just like many of my other recipes. I love changing it up from time to time or adding something special. Take a peek at these ideas to try out:

  • Butterscotch Chips – If you love butterscotch, then it makes sense to add 1/4 – 1/2 cup of butterscotch chips to the cookie dough. After the batter is mixed, just fold in the chips for a sweet treat. 
  • Chocolate – I’m sure you already know, but chocolate and oatmeal are a match made in heaven. Either use your favorite chocolate chips or chop up some semi-sweet chocolate to the dough. 
  • Raisins – I know there are a lot of people that only like oatmeal cookies if there are raisins in them. If you are one of those people, you are in luck! You can easily toss in a few raisins after mixing the batter. 
  • Dried Cranberries – Adding dried cranberries enhances the flavor and texture of these homemade oatmeal cookies. 

How Do You Store Chewy Oatmeal Cookies?

You can store the oatmeal cookies on the counter or in the fridge, depending on your preference. If you opt to keep them on the counter or in the pantry, they will last around 3 days as long as they are airtight. 

A refrigerator is an excellent option if you want the cookies to last a really long time. Put them in an airtight bag or container and refrigerate them for up to 10 days. They are perfect if you are hosting a party and need to be able to make them ahead of time.
