Ingredient Notes:
- Brown sugar – light or dark brown sugar can be used in this recipe. I personally like to use dark brown sugar for a deeper flavor.
- Oats – this recipe called for rolled oats (aka old fashioned) which give the bars their chewy texture. You can use quick oats, but note that the texture will be different.
- Chocolate – I like to use bittersweet chocolate chips, but feel free to use your favorite chocolate chips or chopped chocolate!
How to Make Oatmeal Chocolate Chip Cookie Bars
Expert Tips
- Line your pan with parchment paper. Lining your pan with parchment paper overhanging the sides makes for easy removal after the bars are baked. If you don’t have any parchment paper, you can totally bake the cookie bars without it. Just make sure to grease your pan before spreading the batter.
- Bake in a 9×13-in pan. To bake this recipe in a 9×13-in baking pan, simply double the quantities in the recipe. The baking time remains the same.
- Serving the cookie bars. Once the bars are baked, I like to top them with a sprinkle of sea salt. You can serve them plain, or with a scoop of vanilla ice cream.

I tried this recipe today and reduced the amount both of the sugars by 20% and the chocolate chip to 50 grams but combined it with 35 grams chopped almonds and turns out perfectly not too sweet as i imagined..
great recipe! Thank youu 🙂
Dang that 50g carb lol i love this as it has oats but can I do something to cut back on sugar? Pretty please?
Hi Perrie, the nutrition count is for 8 larger bars, but you can most definitely cut the bars into 16 squares, which will cut the carbs and sugar in half.
I tried this recipe last weekend and it was a hit! I did have to put the whole stick of butter though because it just wasn’t giving me the smooth texture when I was creaming it with sugars. I am going try adding walnuts or coconut flakes to it next time. Thanks for all your hard work and efforts for this recipe!
Thank you, Laila!! Walnuts and coconut flakes would be delicious!
