Key Ingredients

One of the great things about these oatmeal cookies is that they utilize basic ingredients you’re likely to have on hand. As a result, this is a great recipe to keep in your back pocket for those times when you need dessert in a pinch. Here are the primary ingredients you’ll need: 

  • All-purpose flour – This forms the base of the cookies, helping them hold their shape. If desired, feel free to swap out half of the regular all-purpose flour for a whole wheat variety for a boost of extra fiber. 
  • Spices – Cinnamon and nutmeg provide a subtle warm flavor that balances out the sweetness of the sugar. 
  • Unsalted butter – Used to add moisture and richness. 
  • Sugar – A combination of granulated and brown sugars is used to sweeten the dough, providing a caramel-like flavor and keeping it soft and moist. 
  • Eggs – Room temperature eggs bind the batter together. 
  • Old-fashioned rolled oats – Unlike other varieties of oats, rolled oats are hearty, toothsome, and bake wonderfully, adding extra texture to these oatmeal cookies.

Baking Tips for Easy Oatmeal Cookies

Follow the tips below, and these easy oatmeal cookies are a breeze to make. The only hard part is waiting for them to cool before digging in! 

  • Use Room Temperature Ingredients. Let your ingredients sit out and come to room temperature before combining them together. This allows for easy mixing, creating cookies that are soft and moist. 
  • Measure Carefully. When it comes to baking, using proper measurements is crucial. For the best results, we recommend using a scale to portion out all of the ingredients. If this is not an option, use the spoon and level method instead, and make sure to pack your brown sugar tightly. 
  • Beat Carefully. Take your time beating the butter and sugars together until they’re light and fluffy. It will require at least 2-3 minutes of beating but is essential to create the best texture. 
  • Avoid Overmixing. Be sure to mix the ingredients just until they are well combined. Continuing to mix will overwork the dough, resulting in tense, tough oatmeal cookies. 
  • Don’t Overbake. Keep a close eye on your oven, and remove the cookies as soon as the edges are browned and set. The centers may still look a little underdone, but they will continue to bake and firm up as they cool.

How to Store Oatmeal Cookies

Once baked, these easy oatmeal cookies keep well. Or, you can easily store the dough to make later. As a result, they’re great to prepare in bulk for a satisfying treat! Follow the tips below to keep them fresh. 

Room Temperature: Once baked and fully cooled, these oatmeal cookies can be transferred to an airtight container or sealable bag and stored at room temperature for up to 1 week

Refrigerator: If you want to prepare in advance, you can form the dough, transfer it to a sealable container, and keep it in the fridge for up to 4 days before baking this oatmeal cookie recipe. 

Freezer: Both the baked cookies and the dough can be frozen and saved for later. Once assembled, the dough should be wrapped tightly and frozen for up to 3 months. Meanwhile, fully baked cookies can be stored in an airtight container in the freezer for up to 2 months. Then, thaw them in the fridge. Or, cook the dough from frozen, adding a minute or two of baking time as needed to ensure the oatmeal cookies bake all the way through. 

Oatmeal Cookies Common Questions

Can I use a hand mixer for this oatmeal cookie recipe? 

Yes. We recommend using a hand mixer to combine the wet ingredients. Then, use a rubber spatula to gently fold in the oats to avoid overmixing the dough. 

Is this recipe for oatmeal cookies gluten-free? 

No. All-purpose flour contains gluten. However, feel free to swap it out with a 1:1 all-purpose gluten-free flour alternative, and make sure to use oats that are certified gluten-free, if needed. 

Why did my oatmeal cookies turn out hard? 

If your oatmeal cookie recipe turns out hard or tough, it’s likely either because the batter was overmixed or the cookies were overbaked. Be sure to combine the ingredients just until they’re smooth. Then, keep a close eye on your cookies, and remove them from the oven when the edges are puffy and golden brown and the center still looks just slightly underdone.
