Ingredients
- White Sugar: Adds sweetness and helps create a slightly crisp texture on the edges.
- Brown Sugar: Adds sweetness, moisture, and a subtle caramel flavor, contributing to the chewiness.
- Vegetable or Canola Oil: Adds moisture and richness, helping to keep the bars soft.
- Butter: Provides flavor, richness, and a creamy texture, helping to create a tender crumb. (I use salted, but unsalted works too.)
- Eggs: Bind the ingredients together, add moisture, and help the bars rise slightly.
- Vanilla Extract: Enhances the overall flavor with a warm, sweet note.
- All-Purpose Flour: Provides structure and stability, forming the base of the bars.
- Salt: Enhances the flavors and balances the sweetness. (Sea salt is my choice.)
- Baking Powder: Helps the bars rise, creating a lighter texture. (I recommend using aluminum-free baking powder.)
- Baking Soda: Works with the baking powder to help the bars rise and become tender.
- Quick Oats: Add a chewy texture, a nutty flavor, and a hearty, wholesome element. (For variety in texture, you could use half quick oats and half rolled oats.)
- Chocolate Chips: Provide bursts of rich, sweet chocolate throughout the bars. (Use your chocolate of choice. I like dark chocolate.)
Each ingredient plays a role in creating the texture, flavor, and structure of the oatmeal chocolate chip bars, resulting in a delicious and satisfying treat.

Step-by-Step Instructions
Making these chewy oatmeal chocolate chip bars with quick oats is super easy, especially if you have a large Kitchen-Aid mixer, but you can mix them by hand as well.
Preheat Oven:
- Preheat your oven to 350°F (175°C).
Prepare Wet Ingredients:
- Place the white sugar, brown sugar, oil, butter, eggs, and vanilla extract into a large mixing bowl.
- Using a hand mixer or stand mixer, mix the ingredients well until the mixture is nice and creamy.
Prepare Dry Ingredients:
- In a separate large bowl, whisk together the flour, salt, baking powder, baking soda, and quick oats until well combined.
Combine Wet and Dry Ingredients:
- Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix. Stir in the chocolate chips.
Prepare Baking Pan:
- Grease a 13 x 18-inch sheet pan (½ sheet pan) with cooking spray or butter.
Spread Batter:
- Spread the batter evenly onto a 13 x 18" sheet pan (a half-sheet pan, not a jelly-roll pan).


Bake:
- Bake in the preheated oven for about 20 minutes, or until the bars are set and lightly browned around the edges. Do not overbake, as overbaking always leads to dry baked goods.
Cool:
- Allow the bars to cool completely in the pan on a wire rack before cutting.
Cut and Store:
- Once cooled, cut the bars into squares or rectangles.
- Store in an airtight container. For longer storage, freeze any bars you won't eat within a few days. Anytime you get a craving for a sweet treat, simply remove a bar from the freezer, thaw, and enjoy!

Variations
Substitute the chocolate chips for raisins, and turn these into Oatmeal Raisin Bars. For a different twist, make these oatmeal bars with craisins and white chocolate chips. Add chopped nuts, mini M&Ms, or whatever else you think sounds good.

Health Benefits of Oatmeal
Even though we all know that baked goods made with sugar, fats, and flour are not healthy for us, there are benefits to eating oats.
They are high in fiber and antioxidants and are a great addition to a heart-healthy diet.
If you enjoy oats, perhaps you'd like to try my oat fudge bars recipe, granola bars, or honey oat bread. Try my homemade granola cereal recipe or baked oatmeal for a hearty oat breakfast.
Baked Oatmeal Bars
Baking is one of my favorite hobbies. It's so much fun to create delicious food. And I think it would be fun to run a bakery/deli/coffee shop someday. But I don't know if that will ever happen.
So for now, I have fun baking for my family. And with six of us in the house, it sure doesn't take long for food to disappear.
Whenever I bake cookies or bars, I usually make a large batch and put some in the freezer. It keeps them fresh, and I also have hopes that maybe they won't all get eaten as quickly if they're not sitting out where everyone sees them. 🙂

Recommendation for serving bars...
A good bar scoop is a must-have. I found a cheap one at a garage sale and used it all the time until one day it got legs and walked off. I am missing it so much and need to get myself a new one because they are the perfect size for scooping and serving bars and so many other things like lasagna, etc.
And men, if your wife likes to bake and doesn't have a big stand mixer, here's a great idea for her next birthday gift ;). I would be lost without my KitchenAid mixer.
