Ingredients

For the Batter

• 1 cup (2 sticks) butter, softened
• 2 cups packed brown sugar
• 3 large eggs
• 2½ cups all-purpose flour

For Flavor and Texture

• 1 tablespoon vanilla extract
• 2 teaspoons baking powder
• 1 teaspoon kosher salt

For the Chocolate

• 1½ cups semi-sweet chocolate chunks
• 1 cup milk chocolate chips

Instructions

1. Prepare the Baking Dish

Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving some overhang on the sides for easy lifting. Lightly spray the parchment paper and any exposed edges of the pan with nonstick cooking spray.

2. Cream the Butter and Sugar

In a large mixing bowl, use an electric mixer to beat the softened butter and brown sugar together until light, creamy, and fluffy, about 2 minutes.

3. Add the Wet Ingredients

Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract, baking powder, and kosher salt. Continue mixing until the batter is smooth and fully combined.

4. Incorporate the Flour

Reduce the mixer speed to low and gradually add the flour. Mix just until the flour disappears and no dry streaks remain. Avoid overmixing to keep the bars tender.

5. Fold in the Chocolate

Using a spatula or wooden spoon, gently fold the semi-sweet chocolate chunks and milk chocolate chips into the batter until evenly distributed.

6. Bake the Bars

Spread the thick batter evenly into the prepared baking pan and smooth the surface. Bake for approximately 30 minutes, or until the edges are lightly golden and the center is just set.

7. Cool and Slice

Allow the bars to cool in the pan for 10–15 minutes. Using the parchment paper overhang, carefully lift the bars from the pan and transfer them to a wire rack. Let them cool completely before cutting into squares.

Conclusion

These Congo Bars deliver everything you could want in a dessert bar—rich buttery flavor, chewy texture, and plenty of melty chocolate in every bite. They’re simple to prepare, stay moist for days, and are perfect for sharing with friends and family. Whether served with a cold glass of milk, a scoop of vanilla ice cream, or enjoyed on their own, these irresistible bars are sure to become a favorite in your baking collection.
