How to Cook No-Bake Oatmeal Cookies From Scratch?
- Prep: First, line two baking sheets with parchment paper or wax paper.
- Cook milk mixture: Then, combine sugar, butter, and milk in a large saucepan. Cook with medium heat until the butter is melted, stirring occasionally. After the butter melts, turn up the heat to medium-high, and bring to a full rolling boil. Keep it at a full boil for one minute.
- Add the rest of the ingredients: After, remove the saucepan from heat, and stir in the vanilla, peanut butter, and salt until smooth. Then add the oats and stir well.
- Make the cookies: Next, use a cookie scoop or tablespoon to drop cookies onto the prepared pans in a cookie shape. Make sure to leave about an inch between them because they will spread as they set.
- Refrigerate and serve: Last, refrigerate for one hour, or until cookies set, before serving.
Try a few of these varieties to mix things up next time. These are the easiest cookies, and this simple recipe can be adapted with the variations below.
Try making a chocolate version to indulge your sweet tooth or use tahini or sunflower seed butter instead of peanut butter if you have a family member with a peanut butter allergy.
- Crunchy peanut butter: Try crunchy instead of creamy peanut butter for chunky cookies.
- Cocoa powder: Add 1/3 cup of unsweetened cocoa powder to the brown sugar mix before cooking on the stovetop for chocolate oatmeal cookies.
- Other nuts: Try using almond butter or cashew butter for a different flavor.
- Almond milk: In addition, you can use almond milk too. It is great for those who are lactose intolerant and even adds a bit more sweetness to your no-bake cookies.
- Nutella: Make no-bake oatmeal cookies with Nutella or another hazlenut spread instead of peanut butter for a more chocolatey flavor.
- Tahini cookies: If you do not like the taste of peanut butter, try using tahini or sunflower butter. These are made with ground sunflower seeds instead of peanuts. You may have to add more sugar to replace the added sugar in the peanut butter.
- Gluten-free: Use gluten-free oats for those who have celiac disease or just cannot tolerate gluten.

Frequently asked questions
What is the difference between old-fashioned oats and rolled oats?
Actually, they are old-fashioned rolled oats, so they are the same thing. These are flattened oats that absorb more water than steel-cut oats. The steel-cut oats take longer to cook because they are not flattened. There are also two other types of oats.
Quick oats are easy to cook on the stove in a few minutes. You can also microwave them for two minutes. Instant oats are what you find in the little individual packaged oats that are finely chopped and only need one minute in the microwave.
Can I use other oats for this recipe?
You can typically substitute your old-fashioned oats with quick oats in this recipe. However, if the recipe asks for quick oats and all you have are old-fashioned or rolled oats, just put them in a food processor or blender and pulse them a few times.
Why won’t my cookies set?
If your cookies are gooey and do not set, the oats have probably not boiled long enough. The cookies will not stick together and harden unless they reach the soft ball stage. On the other hand, if they are dry and crumbly, you may have cooked them too long.
How to store leftovers:
- Store: Store these no-bake oatmeal cookies at room temperature in an airtight container for three days or keep them in the fridge for up to a week.
- Freeze: If you make too many, let them cool to room temperature and then put them in the freezer on a baking sheet lined with parchment paper until they are frozen. Then, put them in a freezer bag with wax paper between each cookie. Eat within one month for best results.
- Thaw: Do not forget to thaw these overnight in the fridge before serving chilled or at room temperature.
- Make sure not to boil these too long or they will be crumbly.
- Alternatively, if the oats do not boil long enough, they will be too gooey and will not harden.
- Add oats one cup at a time for soft and chewy oatmeal cookies. Stop adding when the dough is thick enough for your taste.
- To make sure your cookies set, use a candy thermometer to check the temperature. The soft ball stage is 235 degrees F so try to get to that temperature.
- If you only have salted butter, just omit the salt from the recipe.
- Also, it is important to use real butter in this recipe. Margarine will not set up the right way.
