Soft, chewy oatmeal cookies were ones my Grandmother kept in a little cookie jar on her counter. Every time my family and I visited her, she had a plate of oatmeal cookies and a glass of cold milk waiting just for me.

Ingredients
Ingredient Notes
See below for ways to use leftover ingredients.
- Butter:3 tablespoons of melted salted butter add flavor and buttery goodness to each bite. I love using melted butter instead of softened butter in this recipe. With melted butter, you'll get moist, chewy cookies every time.
- Sugar: Use granulated sugar and brown sugar. Sugar not only adds sweetness but also provides structure and tenderness. If you don't have brown sugar, try our easy homemade brown sugar recipe.
- Egg yolk: 1 egg yolk is all that is needed in this small batch oatmeal cookie recipe. The egg yolk helps bind the ingredients together. Please see below for ways to use up the leftover egg white.
- Vanilla extract: Provides flavor.
- Flour: Use all-purpose flour which gives structure to the cookies. This recipe has not been tested with other types of flour.
- Baking soda: Baking soda helps the cookies rise.
- Ground cinnamon: Cinnamon is a wonderful addition! You're using just a hint in the batter and it adds a subtle flavor.
- Salt: Salt enhances the flavors in sweet baked goods.
- Oats: For best results, use old-fashioned oats.
How To Make A Small Batch Of Oatmeal Cookies
Follow these easy steps to make the best oatmeal cookies ever!
See the recipe box below for ingredient amounts and full recipe instructions.
- Heat oven to 325 degrees F (165 degrees C). Line the cookie sheet with parchment paper or a Silpat liner.
- In a medium-sized bowl, mix together the melted butter, brown sugar, and granulated sugar until well blended.
- Beat in the egg yolk and the vanilla extract until creamy. Set the bowl aside.
- In a separate small bowl, mix together the flour, baking soda, cinnamon, and salt.
- Mix the flour mixture into the butter mixture until well blended.
- Stir in the oats.
- Use a medium-sized cookie scoop or 1 large tablespoon to scoop out the cookie dough. Place cookies 2-inches apart on the cookie sheet. Bake for 8 to 10 minutes.
- Let the cookies cool for 5 minutes on a cookie sheet then transfer them to a cooling rack to finish cooling.
Expert Tips
- Measure the flour correctly: This is so important. To measure flour correctly, stir the flour in its container with a spoon. Then, use a spoon to scoop flour into a dry measuring cup and slightly overfill. Then, use the back of a knife or other straight-edged utensil to level the flour across the cup. Do not scoop the flour. When you scoop, the flour gets packed too tightly and you will end up with more flour than the recipe calls for.
- Line the cookie sheet: Use a baking mat or parchment paper to line your cookie sheet. I don't recommend coating your baking sheet with butter or oil spray because it creates an overly greasy sheet that will make your cookies spread.
- Do not overbake: Remove the cookies from the oven when the edges begin to lightly brown.
- Portion out the cookie dough evenly: I use a cookie scoop that holds about 2 to 2.5 tablespoons of cookie dough. Using this size will yield 4-5 cookies.
Frequently Asked Questions
Old-fashioned rolled oats are the best oats to use when making oatmeal cookies. Do not use steel-cut oats, they will be too hard, or instant oats which will become mushy.
Store oatmeal cookies in an airtight container at room temperature for up to 1 week.
Although I don't think these soft oatmeal cookies need a thing, you may like to add a drizzle of icing to yours. Here's how to make the cookie icing:
In a small bowl stir together ⅓ cup of powdered sugar, ¼ teaspoon of vanilla extract, and 1 teaspoon of milk or cream. You may find you need to add more milk to get your preferred icing consistency. Spoon over cooled cookies. Allow the icing to set for 15-20 minutes before enjoying.
If you'd like to make a small batch of oatmeal chocolate chip cookies, reduce the amount of oats to ¼ cup and add ¼ cup of semi-sweet chocolate chips.
Reduce the amount of oats to ¼ cup and add ¼ cup of raisins.
