Congo Bars
Congo bars are a classic dessert bar known for their rich buttery texture, deep brown sugar flavor, and soft chewy center loaded with chocolate chips and nuts. Often described as a cross between blondies and chocolate chip cookie bars, Congo bars are thick, decadent, and incredibly easy to make.
Unlike traditional brownies, Congo bars do not contain cocoa powder in the batter. Instead, brown sugar creates their signature caramel-like flavor and chewy texture. They are perfect for bake sales, holiday dessert platters, potlucks, or anytime you want a simple homemade dessert that everyone loves.
With crisp edges, soft centers, and melted chocolate in every bite, these bars are always a crowd favorite.

- ⅔ cup unsalted butter, melted
- 2 cups brown sugar, packed
- 3 large eggs
- 1 tablespoon vanilla extract
- 2 cups semi-sweet chocolate chips
- 1 cup chopped walnuts or pecans (optional)
Equipment Needed
- 9×13-inch baking pan
- Mixing bowls
- Whisk or electric mixer
- Spatula
- Parchment paper
Step-by-Step Directions
Step 1: Prepare the Baking Pan
Preheat your oven to 175°C (350°F).
Grease a 9×13-inch baking pan or line it with parchment paper for easy removal.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together:
- Flour
- Baking powder
- Salt
Set aside.
Step 3: Combine Butter and Brown Sugar
In a large mixing bowl, stir together the melted butter and brown sugar until smooth.
The brown sugar gives Congo bars their signature chewy texture and caramel flavor.
Step 4: Add Eggs and Vanilla
Add the eggs one at a time, mixing well after each addition.
Stir in the vanilla extract.
Step 5: Add the Dry Ingredients
Gradually fold the flour mixture into the wet ingredients.
Mix just until combined.
Avoid overmixing to keep the bars soft and tender.
Step 6: Fold in Chocolate Chips and Nuts
Stir in the chocolate chips and chopped nuts if using.
Reserve a small handful of chocolate chips for topping if desired.
Step 7: Spread the Batter
Spread the thick batter evenly into the prepared baking pan.
Sprinkle extra chocolate chips on top for a bakery-style appearance.
Step 8: Bake
Bake for 25 to 30 minutes or until the edges are golden brown and the center is just set.
Do not overbake. Slightly underbaking helps keep the bars chewy.
Step 9: Cool and Slice
Allow the bars to cool completely in the pan before slicing into squares or rectangles.
Cooling helps the bars firm up and makes cleaner cuts.
