Weekends are my weakness when it comes to sweets. I usually go for cookies or bars of some sort because I can always count on having the ingredients on hand.

These Oatmeal Chocolate Chip Cookie Bars are a regular, sweet-tooth-satisfying weekend treat at our house!. Chewy, chocolate and oat goodness in every single bite!

How to make Oatmeal Chocolate Chip Cookie Bars:

Make the cookie dough as directed, adding half of the chocolate chips.

Press half the dough into a 9×13” baking pan and sprinkle the top with the remaining chocolate chips.

I often use different type of chocolate in these bars, depending on what I have on hand. Usually a mixture of half semi-sweet and half milk chocolate chips. If I have a chocolate bar I will chop it into chunks and use it, along with chocolate chips.

Add the rest of the dough on top and smooth, as best you can, into an even layer.

Bake until slightly golden and set. Allow to cool completely before serving.

  1. Great bar cookies and less time consuming than cookies. I used 12 of chocolate chips, 1/2 c of raisins and 1/4 c of chopped pecans. Yummy!

  2. I rarely leave comments but these where absolutely delicious! My grandson asked me to make something delicious for his church group, so I used this one and they were devoured!
    I made them as is, wouldn’t change a thing
