Classic Congo Bars are a vintage dessert favorite known for their rich, buttery flavor, chewy texture, and irresistible chocolate chip goodness. Often described as a cross between blondies and chocolate chip cookies, these old-fashioned bars have been loved for generations thanks to their simple ingredients, easy preparation, and bakery-style results.
Perfect for bake sales, potlucks, lunchbox treats, or an everyday dessert, Congo Bars deliver deep brown sugar flavor with a soft center and lightly crisp edges.
Ingredients
¾ cup unsalted butter, melted
2 cups brown sugar, packed
2 large eggs
1 teaspoon vanilla extract
2 cups all-purpose flour
½ teaspoon baking powder
½ teaspoon salt
1½ cups chocolate chips
½ cup chopped walnuts or pecans (optional)
Instructions
Preheat and prepare pan
Preheat oven to 350°F (175°C). Grease or line a 9×13-inch baking pan with parchment paper.
Mix the batter
In a large bowl, whisk together melted butter and brown sugar until smooth. Add eggs and vanilla extract, mixing until well combined.
In a separate bowl, whisk together flour, baking powder, and salt. Gradually stir the dry ingredients into the wet mixture just until combined. Fold in chocolate chips and nuts, if using.
Bake
Spread the batter evenly into the prepared pan. Bake for 25–30 minutes, or until the top is set and lightly golden. A toothpick inserted in the center should come out with a few moist crumbs.
Cool and slice
Allow the bars to cool completely in the pan before slicing into squares.
Serving and Storage Tips
Serve Congo Bars at room temperature or slightly warmed. They pair perfectly with milk, coffee, or ice cream.
Store in an airtight container at room temperature for up to 4 days or refrigerate for up to 1 week. These bars also freeze well for longer storage.
Variations to Try
Use white chocolate or butterscotch chips instead of chocolate chips.
Add shredded coconut for extra texture.
Sprinkle flaky sea salt on top before baking for a sweet-salty finish.
Swirl in peanut butter for a rich twist.
Why This Recipe Works
Using melted butter and brown sugar creates a moist, chewy texture with deep caramel notes. Baking just until set keeps the bars soft and tender instead of cakey.
Final Thoughts
Classic Congo Bars are a timeless, no-fuss dessert that delivers big flavor with minimal effort. Rich, chewy, and loaded with chocolate, these nostalgic bars are guaranteed to become a repeat favorite in any home kitchen.
