There are thousands of Oatmeal Cookies out there. Everyone has their favorite, and this one is mine.
It’s an easy recipe made with simple ingredients. No mixer required! Excellent both with and without raisins.
Your cookie jar won’t stay full for long. They are hard to resist!
Table of Contents
- old-fashioned oatmeal
- all-purpose flour
- baking powder
- ground cinnamon
- butter unsalted (room temperature)
- white sugar
- brown sugar
- 1 egg (room temperature)
- vanilla extract
- sweet raisins (optional)
Room temperature butter and eggs help in mixing the dough easily.
For the raisin haters, swap out for 1 cup of chocolate chips or white chocolate chips.
Just like high protein overnight oats, these cookies are also great for breakfast.
- Mix the old-fashioned oats, flour, baking powder, cinnamon, and salt in a medium bowl.
Do not substitute old fashioned oatmeal for instant oats. The two are not interchangeable and will not bake properly if using the latter.
Quick oats will not work either. Learn more – Are Oats Gluten-Free?
I prefer wheat flour, but you can also use all purpose white flour.
- In a separate, large bowl, add the unsalted butter and the two types of sugar. Beat until creamy.
- Add the egg, vanilla, and honey. Beat for another two minutes.
Here, we are using dark brown sugar which has more molasses in it. That’s why the color of the cookies are darker.
Use light brown sugar for a less intense brown color and milder flavor.
Good news! Dark brown sugar and light brown sugar are interchangeable.
- Add the dry ingredients to the wet ingredients little by little.
- Mix until well blended.
- Add 1 cup raisins and mix well.
- Put the mixing bowl in the fridge and chill the cookie batter for 30 minutes.
If doing this in the mixer, do this at low speed so the flour won’t go everywhere.
Be sure to scrape the bottom of the bowl so everything gets mixed properly.
Whatever you do, don’t overmix! Or you’ll end up with tough cookies instead of soft cookies.
Freezing Cookie Dough:
Chill for 1 hour in the fridge. Then wrap in plastic wrap and place inside a freezable bag, removing as much air as possible. Store for up to 3 months in the freezer. Bake as normal.
- Make dough balls using a large spoon.
- Put them on a cookie sheet with parchment paper.
- Preheat oven to 350 degrees F and bake for 16 to 18 minutes, or until golden brown.
Let them cool on the baking sheet for a minute or two before placing on a cooling rack. They are soft and can fall apart.
The dough balls are about the size of a golf ball.
This recipe yields 11 to 12 large cookies. Try making smaller dough balls to make more cookies.
Frequently Asked Questions
Should you soak raisins before baking cookies?
To make plump raisins, soak them in water before adding to the cookies. I only do this when the raisins look dry or are older.
Why do my oatmeal raisin cookies get hard?
Are raisin oatmeal cookies healthy?
Cookies are not healthy snacks, but they are better than most cookies. These types of cookies also contain whole grains and are made with natural ingredients.
An occasional cookie, eaten in moderation is ok for most diets.
Store cookies 3-4 days in an airtight container at room temperature. To store in the freezer, place in a freezer bag and remove as much air as possible. They store well for up to 3 months in the freezer. Thaw for 1-3 hours before consuming.
