Why You'll Love This Recipe
About the Ingredients
1 cup (226g) unsalted butter, softened
Butter adds richness and helps create a chewy texture. For a dairy-free option, use vegan butter or coconut oil (solid).
3/4 cup (150g) packed brown sugar
Brown sugar keeps cookies moist and adds a deep caramel flavor. If you're out, you can substitute with coconut sugar or a mix of white sugar and molasses.
1/4 cup (50g) granulated sugar
Granulated sugar helps with spreading and crisp edges. You can use all brown sugar for a chewier cookie, but reduce the liquid slightly.
1 large egg
Egg binds the dough and adds structure. For an egg-free version, use a flax egg (1 tbsp ground flax + 3 tbsp water).
1 teaspoon vanilla extract
Vanilla enhances the flavor. Use pure vanilla extract for the best taste; you can also use vanilla bean paste or a pinch of vanilla powder.
1 1/2 cups (180g) old-fashioned rolled oats
Rolled oats give the signature chewy texture. Do not use instant oats, as they will make the cookies dry. For gluten-free, use certified gluten-free oats.
1 cup (125g) all-purpose flour
Flour provides structure. For a whole-grain twist, use whole wheat pastry flour or a 1:1 gluten-free baking blend.
1/2 teaspoon baking soda
Baking soda helps cookies rise and spread. Make sure it's fresh for optimal lift; you can test by adding a drop of vinegar to a pinch.
1/2 teaspoon ground cinnamon
Cinnamon adds warmth. You can use pumpkin pie spice or apple pie spice as a substitute.
1/4 teaspoon salt
Salt balances sweetness and enhances flavors. Use fine sea salt or table salt; if using kosher, increase to 1/2 teaspoon.
Tips & Tricks
Measure flour correctly
spoon it into the cup and level off with a knife. Too much flour makes cookies dry and dense.
- Use old-fashioned oats, not instant, for the best chewy texture. Instant oats will result in a mushy, dry cookie.
- Don't overmix the dough once the flour is added—mix just until combined to avoid tough cookies.
Pro Tips
Step-by-Step Instructions
1. Preheat and Prep
Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone mats. This ensures even baking and prevents sticking.
2. Cream Butter and Sugars
In a large bowl, beat the softened butter, brown sugar, and granulated sugar together until light and fluffy, about 2-3 minutes. This incorporates air, giving the cookies a tender texture.
3. Add Egg and Vanilla
Beat in the egg and vanilla extract until fully combined. Scrape down the sides of the bowl to ensure everything is evenly mixed.
4. Mix Dry Ingredients
In a separate bowl, whisk together the oats, flour, baking soda, cinnamon, and salt. This ensures the leavening and spices are evenly distributed.
5. Combine Wet and Dry
Gradually add the dry ingredients to the wet mixture, stirring with a wooden spoon or spatula until just combined. Do not overmix; a few streaks of flour are okay.
6. Scoop Dough
Drop rounded tablespoons of dough (about 1.5 inches in diameter) onto the prepared baking sheets, spacing them 2 inches apart. For uniform cookies, use a cookie scoop.
7. Bake to Golden Perfection
Bake for 10-12 minutes, or until the edges are golden brown and the centers are still slightly soft. Rotate the pans halfway through for even baking. The tops should look set, but a gentle press should leave a slight indentation.
8. Cool and Enjoy
Let the cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely. The cookies will continue to set as they cool.
Delicious Variations
- Add 1/2 cup (85g) raisins or dried cranberries for a classic oatmeal raisin cookie.
- Mix in 1/2 cup (85g) chocolate chips for a chocolatey twist.
- Fold in 1/2 cup (60g) chopped walnuts or pecans for extra crunch.
How to Store Easy Quick Oatmeal Cookies
Refrigerator
Store in an airtight container at room temperature for up to 5 days. To keep them chewy, add a slice of bread to the container.
Freezer
Freeze baked cookies in a freezer-safe bag for up to 3 months. Separate layers with parchment paper.
Reheating
To refresh, microwave a cookie for 10 seconds or warm in a 300°F (150°C) oven for 5 minutes.
Frequently Asked Questions
Q: Can I use quick oats instead of rolled oats?
Yes, you can, but the texture will be softer and less chewy. Quick oats absorb more liquid, so the cookies may spread more and be slightly denser. For best results, stick with rolled oats.
Q: Why are my cookies flat?
Flat cookies usually result from butter that is too soft or melted, or from too little flour. Make sure your butter is softened but not melted, and measure your flour correctly by spooning and leveling.
Q: Can I make these cookies gluten-free?
Absolutely. Use certified gluten-free rolled oats and substitute the all-purpose flour with a 1:1 gluten-free baking blend. The texture may be slightly different, but they will still be delicious.
Q: How do I make these cookies vegan?
To make vegan cookies, replace the butter with vegan butter or coconut oil, and use a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water) instead of the egg. The cookies will still be chewy and flavorful.
