Easy chocolate chip oatmeal cookie recipe makes tasty oatmeal cookies in less than 30 minutes. These simple chocolate chip oatmeal cookies are made in one bowl and are made with all brown sugar.

Baking cookies should be easy, and these easy chocolate chip oatmeal cookies are just that.
Since the butter is melted, there’s no need to soften the butter before beginning. The cookies are also made in one bowl, so there’s one less bowl to wash.
Ingredient notes and substitutions
- Butter: I use salted butter in this recipe. If using unsalted butter, increase the butter by 1/2 teaspoon. Also, I melt the butter about 85% of the way and then whisk until completely melted. Butter that is too hot will give you greasy cookies.
- Brown sugar: Either light brown sugar or dark brown sugar will work in this recipe.
- Flour: It’s important to properly measure the flour so that you don’t end up with dry, crumbly dough. You can weight it (click on “metric” for the weights) or sift the flour, lightly spoon into a measuring cup, and level.
- Chocolate chips: Feel free to use milk chocolate chips, dark chocolate chips, or even flavored chips in this recipe.
How to make easy chocolate chip oatmeal cookies
Here you’ll find step-by-step photos showing how to make this recipe. The full recipe, including ingredients, is given below.
Step 1: Preheat oven to 375 F. Line baking sheets with parchment paper or silicone baking mat.
Step 2: Melt butter in a large microwave-safe bowl.

Step 3: Add brown sugar, and stir to combine. Let stand 5 minutes.

Step 4: Add egg and egg yolk; stir to combine.
Step 5: Stir in vanilla extract.

Step 6: Add flour, baking soda, and salt. Stir until just combined.

Step 7: Stir in oats until just combined.

Step 8: Add chocolate chips and nuts, if using, and stir in.

Step 9: Using a medium cookie scoop (1.5 tablespoon), drop scoops of dough 2 inches apart on prepared cookie sheet.

Step 10: Bake for about 7-10 minutes, or until the edges of the cookies are golden brown.
Step 11: Let cool on cookie sheet for 5 minutes. Remove to wire rack to finish cooling.

Recipe Tips!
- Mixing: I highly recommend mixing the dough by hand. It’s easy to do, and it helps to prevent overmixing the dough.
- Chilling the dough: You can chill the dough before baking. If you chill the dough, it will give you softer, thicker cookies.
- Baking: Oven temperatures and baking times can vary quite a bit. You may find that you need to adjust your baking temperature and time according to how your oven bakes.

Storage
Store any leftover cookies in an airtight container at room temperature. The cookies will keep for up to 3 days when properly stored.

Great oatmeal cookie recipe Kate. Only way I can get my husband to eat oatmeal.
FYI typo?: In the “notes” section under the butter heading, I think you may have meant if using unsalted butter, increase “salt” by 1/2 tsp, not increase butter. Not nit-picking, but new cooks may not catch it. Even though, as written would not make a huge difference.
Kate says
Thank you, and thank you for letting me know about the typo!

The directions are confusing, or maybe it’s just me. It doesnt say when to remove from heat, I assumed after you combine the butter with brown sugar. I let it stand for 10 minutes and all my chocolate chips melted. I guess I’m not good at following directions
Kate says
Hey! I’m sorry that that was confusing! I appreciate you taking the time to share your feedback, and I added a note about removing from heat to make that clearer.

I made these cookies and they were AWESOME! I have not had good luck with any of the oatmeal cookie recipes I tried. I live in Colorado and its a challenge baking in high altitude. The oatmeal cookies I make usually are great consumed right after baking but get dry later that day and typically is inedible within 3 days. These cookies were still great on day 3! My 3 kiddos could not get enough of these cookies. THANK YOU for this recipe and SOO many others that you provide. We really enjoy all the quick bread recipes and cookie recipes!
Kate says
