Congo Bars Recipe

I absolutely adore chocolate chip cookies and love to make fun (and delicious!) variations of them. This blondie recipe is one of my favorites, as well as chocolate chip cookie pie!

Congo bars AKA chocolate chip cookie bars were a Sunday church cookbook staple at my husband’s house and this was his grandma’s recipe! They have crisp edges, a chewy middle and we love to serve them with homemade vanilla ice cream and hot fudge.

Ingredient Notes

Congo bars ingredients.

Find the full printable recipe below.

  • Brown sugar: Adds the signature flavor and gooey texture in these bars.
  • Salted butter: If using unsalted butter add additional 1/4 teaspoon salt to the dough.
  • Baking staples: Eggs, flour, baking powder, salt and vanilla extract.
  • Semi-sweet chocolate chips: Milk chocolate chips could be used but skip the chocolate chips they are a congo bar classic!
  • Optional: Walnuts and shredded coconut. Some say the addition of coconut is because of where the name originated – Congo, Africa. No one really knows, though!

How to Make Congo Bars

The simple ingredients for these bars come together so easily in one bowl!

  • Preheat oven to 325 degrees. Grease a 12×14 pan and dust lightly with flour.
  • In a large bowl, cream together butter and sugar. Then add eggs and vanilla and stir until combined.
  • Mix baking powder and salt with 1 cup flour. Pour into the butter mixture and stir in rest of flour. Then fold in chocolate chips.
  • Press dough into pan with flour on your hands. Bake for 25 to 35 minutes, until lightly browned and toothpick comes out clean. Allow to cool before cutting.

Tips and Variations

  • Size of pan: I make these congo bars in a 12×14″ pan, however a 9×13″ pan will work. If making in a 12×14″ pan, I usually slice them into 20 squares. When making in a 9×13″ pan, I’ll slice them into 16 squares. Cooking time will vary based on the size of the pan!
  • Test for doneness: To avoid overbaking, test with a toothpick. The toothpick should come out clean (or with a few crumbs) when stuck in the middle of the pan.
  • Customize: Make the dough into 4-in-one sheet pan cookie bars. Just divide dough into 4 bowls and add desired mix-ins to each bowl before placing in pan.
  • Serving: To serve top with ice cream, hot fudge or whipped cream and caramel sauce, too!
