Congo Bars Recipe
Introduction
Congo Bars are a rich, chewy treat bursting with chocolate chunks and gooey centers. Perfect for satisfying any sweet tooth, these bars combine buttery dough with two types of chocolate for an irresistible dessert.

Ingredients
- 1 cup (2 sticks) butter, at room temperature
- 2 cups brown sugar, packed
- 3 large eggs, at room temperature
- 1 tablespoon vanilla extract
- 1 teaspoon Kosher salt
- 2 teaspoons baking powder
- 2 1/2 cups all-purpose flour
- 1 1/2 cups semi-sweet chocolate chunks
- 1 cup milk chocolate chips
Instructions
- Step 1: Preheat your oven to 350°F. Line a 9×13-inch baking dish with parchment paper and lightly grease with nonstick spray. Set aside.
- Step 2: In a large mixing bowl, beat the butter and brown sugar together using an electric mixer on medium speed for about 2 minutes until creamy and well combined.
- Step 3: Add the eggs, vanilla extract, salt, and baking powder to the bowl. Mix again to combine, scraping down the sides of the bowl as needed.
- Step 4: Reduce the mixer speed to low, then gradually add the flour. Mix until just combined—do not overmix.
- Step 5: Fold in the semi-sweet chocolate chunks and milk chocolate chips evenly throughout the dough.
- Step 6: Transfer the dough into the prepared baking dish. Spread it out evenly using a rubber spatula.
- Step 7: Bake in the preheated oven for about 30 minutes, until the edges are set but the center remains slightly underbaked and gooey.
- Step 8: Let the bars cool in the pan for 5 minutes before removing them to cool completely on a wire rack. Once cool, slice into bars and serve.
Tips & Variations
- For extra texture, try adding chopped nuts like walnuts or pecans into the dough.
- Use a mix of dark and milk chocolate chips for a richer chocolate flavor.
- If you prefer a firmer center, bake the bars a few minutes longer, but be careful not to dry them out.
- Make sure your butter and eggs are at room temperature for smoother, more even mixing.
Storage

Ingredients
Wet Ingredients
- 1 cup (2 sticks) butter, at room temperature
- 3 large eggs, at room temperature
- 1 tablespoon vanilla extract
Dry Ingredients
- 2 cups brown sugar, packed
- 1 teaspoon Kosher salt
- 2 teaspoons baking powder
- 2 1/2 cups all-purpose flour
Chocolate
- 1 1/2 cups semi-sweet chocolate chunks
- 1 cup milk chocolate chips
Instructions
- Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Line a 9×13-inch baking dish with parchment paper and lightly grease it with nonstick spray. Set aside to prepare the batter.
- Cream Butter and Sugar: In a large mixing bowl, use an electric mixer on medium speed to beat the room temperature butter and packed brown sugar together for about 2 minutes until the mixture is creamy and well combined.
- Add Eggs and Flavorings: Add the eggs, vanilla extract, Kosher salt, and baking powder to the butter and sugar mixture. Mix everything together until combined, making sure to scrape down the sides of the bowl to incorporate all ingredients evenly.
- Incorporate Flour: Reduce the mixer speed to low and gradually add the all-purpose flour. Mix just until combined to avoid overworking the batter, which keeps the bars tender.
- Fold in Chocolate: Gently stir in the semi-sweet chocolate chunks and milk chocolate chips to evenly distribute them throughout the batter.
- Transfer and Bake: Spread the dough evenly into the prepared baking dish using a rubber spatula. Bake in the preheated oven for approximately 30 minutes, until the edges are set but the center remains slightly underbaked and gooey.
- Cool and Slice: Allow the bars to cool in the pan for 5 minutes before lifting them out using the parchment paper. Let them cool completely on a wire rack, then slice into bars and serve. Enjoy your delicious Congo Bars!
