Oatmeal Chocolate Chip Bars

Sometimes life just calls for ooey-gooey-falls-apart-in-your-mouth chocolate bars. I may be in the minority, but I tend to prefer a slightly under-done bar… one that is best eaten with a spoon. One that is amazing on its own but even better when friends and family can join together around the baking pan with a fork in hand. Have you ever done that? Just let the kids dig in with a fork? It is a bonified memory-maker… one of those things that the kids never forget and will definitely ask for again!

To achieve this ooey-gooey bar, bake for a few minutes less than the recipe suggests. Top with some vanilla ice cream and you have created a magical bar that everyone will love!

Rolled Oats vs. Quick Oats

I used Old-Fashioned oats in my recipe but you can certainly use Quick Oats. We love oatmeal so love the consistency, texture, and flavor that an old-fashioned rolled oat adds. Most people use quick oats and never notice the difference, though!

PRO TIP: Make sure your pan is prepared really well. I like to use baking spray for this specific recipe, but you can also use GOOP, or homemade pan release. If you are using GOOP, make sure to coat the sides of the pan as well.

Homemade Chocolate Oatmeal Bars

This recipe comes together really quickly and is a super fun treat for after school, bake sale, or special event. I like to use good quality ingredients when I can, but I also like to clean out my pantry! 😂 I have made these with different chocolate morsels, quick oats, whole wheat flour, even all granulated sugar instead of brown sugar. They are a hit EVERY time no matter how we modify the recipe!

This is one of those classic recipes that you can modify to fit your tastes. Add raisins or walnuts or white chocolate…  even caramel or toffee! Make up a batch now, let the family dig in, then send the leftovers to school with the kids. I promise this will be one of the best things you will do today!

Whoops. I might have slightly undercooked this batch. #sorrynotsorry

Chocolate Chip Oatmeal Bars

Last time I made these bars they went for $5 each at the bake sale and SOLD OUT!

UPDATE: I made these for another charity event and packaged them the exact same way I did in this post for Fancy Christmas Cakes. (Except that I used white ribbon) They sold out FIRST!! One trick when packaging is to use very chilled bars. I simply cut the bars while they are still in the pan and then chilled them in the pan for about 2 hours in the refrigerator.

Another thing you can do is display them on a cake stand. Get them up higher than all the rest of the treats! Here are my tips for how to find and buy the PERFECT Cake Stand as well as where I store my cake stands! These tips work like a charm and who doesn’t love raising money for charity?

  • 1 cup unsalted butter, at room temperature
  • 1 cup firmly packed light brown sugar
  • 1/2 cup granulated sugar
  • 2 eggs, at room temperature

  3. Add in eggs one at a time, mixing well after each addition.
  4. With mixer on low, add in the vanilla extract.
  5. Remove bowl from stand mixer and add in salt, baking soda, baking powder, flour, rolled oats, plus semi-sweet chocolate chips.

    This looks yummy!!! Can I use whole wheat or any other healthier option instead of white flour? Thanks

    • Amanda says:

      You certainly can, although I have not made the recipe with those options so cannot testify to their effectiveness.

  • Laura @ Laura's Culinary Adventures says:

    I prefer under baked bars and cookies too. These looks yummy!

  • Jackie says:

    I made these for my office cookie swap. They loved them! I added chopped walnuts…so good. They reminded me of one of those gooey chocolate chip cookies from Levain bakery.

    • Amanda says:

      Oh awesome!!

  • Regina says:

    Sounds awesome- I have a large container of quick oats- have you tried with quick vs. rolled? Happy New Year oat bars!

    • Amanda says:

      I have! My family prefers old-fashioned oats but some of the kids at school liked the quick oat version better. 🙂

    • Shanda says:

      Yes I made them with quick Oaks and added some peanut butter thebomb.com

  • Huneybee327 says:

    Made these tonight. Only used the semi-sweet chocolate chips on the inside. I didn’t have milk chocolate chips. My daughter said these are her favorite cookie ever! They are super soft and buttery deliciousness. Thanks for the recipe! ♡

  • Jennifer says:

    I want to try these two ways. One with only semi sweet chocolate chips ( I don’t care for milk chocolate). Then I want to mix butterscotch chips and semi sweet chocolate! The Oatmeal Scotchie has always been my favorite cookie but am willing to add some chocolate!

  • Dixie says:

    Made these over the weekend and they were delicious. I did add a few white and butterscotch chips to use up some partial bags that I had. Wondering if you have any tips for spreading the batter in the pan? I measured the flour correctly, but it stuck like crazy when I tried to spread it.

    • Amanda says:

      I would dip my fingers in flour and gently pat the mixture down. Takes a bit longer but it is worth it. 🙂

  • Norma vacca says:

    I’m going to make these today, don’t have oats, can I use pkts of oatmeal or wait until I get to the store? Looks yummy!

    • Amanda says:

      I guess you could if they are not flavored…

  • Julie says:

    What is the purpose of the bakiing powder and baking soda. I want to make these but those are the only ingredients I don’t have

  • Ashley C. says:

    Sounds yummy! What about for gluten free? I have gluten free oats but what GF flour would you recommend?

  • Beverley Press says:

    I’m making this at the weekend so come on over and make some coffee 🙂 ps love your new look page. xoxo

  • Ashleigh says:

    Perfect treat! Made these with the quick oats and white chocolate chips that I had on hand in the pantry. So yummy! This is like a warm cup of tea on a rainy day, a sense of comfort. Thanks!

  • angela says:

    very good

  • Taj says:

    I will definitely try your oatmeal chocolate chips.Looks delicious….yummy..

  • Patty says:

    The only change I made was to make a powdered sugar glaze to put over top. These were delicious.

  • Teresa Davis says:

    I’m looking forward to trying your oatmeal cookie bar I found on Pinterest.

  • Francine Johnson says:

    I can’t wait to make these. I will be making them as soon as I get home. I will only use milk choc chips and add some PB too. I’ll let you know how it comes out.

  • Jan says:

    Can you use salted butter in this recipe?

    • Amanda says:

      You can. 🙂

  • Anastasia Crispin says:

    How would you modify the sugar if you don’t use brown sugar? I’m excited to try this recipe!

  • Dianna says:

    Can you use regular butter instead of unsalted butter in your chocolate oatmeal bars. Thank you

  • V says:

    I made these last night for a large group of teenage boys. They finished them off rather quickly. I really liked them, much like a square chocolate chip cookie.

    Putting 1/2 the recipe in the pan and spreading it was very tricky and sticky. I had to put flour on my hand and push and pat. I used semisweet and dark chocolate chips, also pecan pieces. Great recipe!

  • Peggy says:

    Do you have a cookbook?

  • Jo Jo says:

    Can you put the oatmeal in a food processor & make oat flour? Awaiting your response.
