My Nana’s congo bars are the ultimate soft, chewy cookie bars loaded with chocolate chips. This vintage recipe has been a family favorite for generations. This delicious sweet treat is always a hit!
I have a huge sweet tooth and so does the rest of my family, especially my kids. If they could pick any dessert it would probably be chocolate chip cookies. But lets be honest, sometimes I don’t have the patience to bake multiple batches of cookies. Thats where this delicious congo bars recipe saves the day. Instead of scooping and baking in batches, I can spread all of the batter in a pan and bake one big chewy, chocolate chip goodness.
This recipe also has a special place in my heart. When I went to college my mom assembled a binder of our favorite family recipes and this congo square recipe is one that I turn to again and again. I like making them for a special treat, to serve at parties, holidays, and more.
These bars are the perfect mix of buttery, chewy, and full of chocolate chips. This is definitely a great recipe for all occasions.

25-30 minutes? Wrong!! They are totally raw except for the top and outer perimeter that is halfway baked. I’m putting my cooled Congo squares back into the oven now. I know they will be crispy-hard. PLEASE adjust to allow at least 38-40 minutes. I think the rest of the recipe is fine.
Wind don’t see how much coconut, nuts or white chocolate chips to add. Am I missing something? I am looking forward to making these for our volunteer firefighters, they love treats!
Hi Sharon! These Congo squares only use chocolate chips, no coconut, nuts or white chocolate. Thanks!
Sharon, I think these are just suggested stir ins. add as much or as little as you’d like. 🙂
