Oatmeal Chocolate Chip Bars

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. These are very similar to one of my all time favorite recipes, commonly known as chocolate revel bars. Main difference is that this recipe does not mix the chocolate chips with sweetened condensed milk. I’ve tried a few variations-butterscotch chips, toffee, etc. Now I’ll have to try this!

  2. These are the very very best bar cookies I’ve ever made. The texture is out of this world. I cannot have chocolate so I did not make layers and I used a cup of Reese’s Pieces and a cup of peanut butter morsels stirred into the batter. After eating these, I do not know if I can ever bring myself to make any other cookie…thank you very much for sharing this recipe!

  3. These are delicious! I baked for 25 minutes, came out nice and gooey. I did add 3/4 cup chopped walnuts to the dry mix. Otherwise, I did not change a thing. It took a little work getting the cookie mixture pressed because it’s so thick. Thank you for a great recipe.

  4. After reading the comments about how many had a hard time spreading the dough, I braced myself for trying to come up with a strategy. Well, I had absolutely no problem at all. I’m guessing because I use duck eggs!
    Anyways, I baked the bars for 30 minutes and they turned out beautiful. Only trouble I had was waiting for the bars to cool and ended up cutting a piece after almost 10 minutes. Needless to say, the warm bars and a cold glass of milk were superb!

  5. I have made these so many times and each time, people rave! I’m too lazy to spend the time layering, so I mix it all together and spread it in my baking dish using wet hands. I put any type of chip or add-in that I have–today I used white chips, milk chocolate chips, dark chocolate chunks and M & M’s! Each batch is different, but great!

  6. Made this for the 1st time the other day, switching up the way we do oatmeal for breakfast and this tastes amazing! So im staying up to make another batch for tomorow! I used all dark chocolate though and my husband, 3 boys, and i love it. Super duper easy to make and super fast too. As a mama of 4 id say this is a must have recipe for a quick fix!
