Do not be hesitate to take 20 minutes to make this dough.  You will not believe how fast they will disappear, you may not be able to save any as the smell of baking cookies fill the house. If the cookies disappearing bothers you the key is to make a double batch. 

Start making oatmeal cookies as an after school treat as they are healthier than a store-bought chocolate chip cookie.  Getting your kids familiar to the oatmeal flavor and texture, you can then try oatmeal muffins, and cooked oatmeal.

What to add to a basic oatmeal cookie

  • Raisins are a traditional addition to oatmeal cookies. However, not all kids love raisins, so you can add to some of the dough if you are a raisin lover.
  • Mini chocolate chips are a fun way to start picky eaters to try a new taste of oatmeal. 
  • Butterscotch chips
  • Dip half of the cookie in melted chocolate chips
  • Frost the cookie

How to make the best disappearing oatmeal cookies

On the day you want to make cookies put the butter and margarine out on the counter to get to room temperature. You can try softening in the microwave but it is very easy to have it just melt. 

Put your oats in the food processor and pulse for about 10 to 12 times. This will give you a ruff grind. 

Mix the wet ingredients in the stand mixer and mix the dry ingredients in a large mixing bowl, whisk the dry to combine. 

Add the dry to the wet and refrigerate 1 hour.  I put the dough back in the refrigerator in between batches of cookies. 

Taking two spoons spoon an amount of dough the size of a silver dollar and flatten with the flat base of a measuring cup. 

Bake until golden brown, 350Β° for 8 to 10 minutes.
