There’s something about the smell of brown sugar, butter, and chocolate baking together that makes a kitchen feel like home. It’s the kind of smell that brings everyone wandering in, asking what’s in the oven and, more importantly, when they can have a taste!
That’s exactly what I love about these Congo Bars. They have all the delicious flavors of a classic chocolate chip cookie, but instead of scooping individual cookies onto baking sheets, you spread the dough into one pan, bake it, and cut it into irresistible squares.
No rolling. No chilling. No baking tray after baking tray of cookies.
Just thick, golden bars with chewy centers, slightly crisp edges, and plenty of melted chocolate chips in every bite.
If you love old-fashioned homemade desserts that are easy enough for a weekday treat but special enough to share with friends, you're going to want to keep this recipe close.
And the best part? These bars are wonderfully simple to make with everyday pantry ingredients!

What Are Congo Bars?
Congo Bars are old-fashioned cookie bars made with a brown sugar-rich dough, eggs, flour, butter, and chocolate chips. They're often compared to chocolate chip cookies, but they're baked in a single pan and sliced into squares or rectangles.
Despite the name, Congo Bars aren't necessarily connected to the Central African country of the Democratic Republic of the Congo. The exact origin of the dessert's name is uncertain, and recipes have appeared in American home baking traditions for generations.
You'll sometimes hear them called chocolate chip cookie bars, blondie-style cookie bars, or Congo Squares.
They're similar to blondies, but many Congo Bar recipes have a flavor and texture closer to a thick chocolate chip cookie.
Think chewy, buttery, brown-sugary goodness with chocolate in every bite!
Why You'll Love These Congo Bars
They're easier than individual cookies
There's no need to scoop dozens of cookies or bake multiple batches. Simply press the dough into a baking pan and let the oven do the work.
They have wonderfully chewy centers
Brown sugar gives these bars a rich, caramel-like flavor and helps create that soft, chewy texture we all love.
They're loaded with chocolate chips
Every square gets plenty of chocolatey goodness. Use semisweet chocolate chips for that classic flavor, or mix in milk and dark chocolate for something extra special.
They use simple pantry ingredients
Flour, sugar, butter, eggs, vanilla, and chocolate chips are all you need for the basic recipe. No special equipment or hard-to-find ingredients required.
They're perfect for sharing
Bring them to a potluck, pack them into lunchboxes, serve them at a bake sale, or set a plate on the kitchen counter for an afternoon treat.
Just don't be surprised if the plate empties faster than you expected!
What Do Congo Bars Taste Like?
Imagine the best parts of a chocolate chip cookie in one thick, satisfying square.
The edges turn golden and slightly crisp, while the middle stays soft and chewy. Brown sugar adds a deep, almost butterscotch-like sweetness, and vanilla gives the dough that familiar homemade cookie aroma.
Then there are the chocolate chips.
Some stay tucked inside the dough, while others melt into little pockets of chocolate that make each bite even better.
They're sweet, buttery, rich, and comforting without needing frosting or an elaborate topping.
Honestly, a slightly warm Congo Bar with a glass of cold milk is hard to beat!
Ingredients You'll Need
This recipe makes one pan of chewy Congo Bars, perfect for cutting into 16 generous squares or smaller portions for a crowd.
- 2 ¾ cups all-purpose flour
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt
- ¾ cup unsalted butter, melted and slightly cooled
- 1 cup packed light brown sugar
- ½ cup granulated sugar
- 2 large eggs, at room temperature
- 2 teaspoons vanilla extract
- 2 cups semisweet chocolate chips
- Shop Candy Gifts
- Optional additions:
- ½ cup chopped pecans or walnuts
- A little flaky sea salt for sprinkling on top
- A quick note about brown sugar
- Brown sugar is one of the ingredients that gives Congo Bars their signature flavor. Light brown sugar creates a lovely caramel note, while dark brown sugar gives the bars a deeper, more molasses-rich taste.
- Either works beautifully!
- Helpful Tools
- You don't need a mixer or fancy baking equipment for this recipe.
- 9-by-13-inch baking pan
- Parchment paper
- Two mixing bowls
- Whisk
- Rubber spatula or wooden spoon
- Measuring cups and spoons
- Cooling rack
- Sharp knife for slicing
- Order Fresh Bakes
- My favorite little trick: Line the baking pan with parchment paper, leaving a bit of overhang on two sides. Once the bars have cooled, you can lift the entire slab out of the pan and cut it neatly on a cutting board.
- Less sticking, easier slicing, and much simpler cleanup!
- Ingredient Additions and Substitutions
- One of the best things about Congo Bars is how easy they are to customize.
- Change the chocolate
- Semisweet chocolate chips are a classic choice, but you can use:
- Milk chocolate chips for a sweeter bar
- Dark chocolate chips for a richer flavor
- White chocolate chips for a creamy contrast
- Chocolate chunks for bigger pockets of melted chocolate
- A mixture of two or three kinds of chocolate
- Get Fresh Dairy
- And if you love chocolate, don't be shy about sprinkling a few extra chips over the top before baking.
- Add nuts
- Chopped pecans or walnuts give the bars a lovely crunch and pair beautifully with brown sugar and chocolate.
- Add about ½ cup to the dough. Toasting the nuts first can bring out even more flavor, but let them cool before mixing them in.
- Make them extra rich
- Replace some of the semisweet chocolate chips with butterscotch chips or peanut butter chips.
- The result is sweeter and richer, so this is a great option if you're making dessert for someone with a serious sweet tooth!
- Use salted butter
- If salted butter is what you have, you can use it. Simply reduce or omit the added salt, depending on your preference and the saltiness of the butter.Find Recipes
- Can you use gluten-free flour?
- A cup-for-cup gluten-free baking flour blend may work, especially one formulated for cookies and bars. However, the texture can vary by brand, so follow the blend's guidance and expect slightly different results.
- How to Make Congo Bars
- These bars come together quickly, so have your ingredients measured before you begin.
- Step 1: Prepare the oven and pan
- Preheat your oven to 350°F (175°C).
- Line a 9-by-13-inch baking pan with parchment paper, or lightly grease it if you prefer.
- Make sure the oven has reached the correct temperature before putting the bars in. An evenly heated oven helps the edges bake properly without leaving the center underdone.
- Step 2: Combine the dry ingredients
- In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.Shop Candy Gifts
- Set the bowl aside.
- This quick step distributes the leavening agents throughout the flour, helping the bars bake more evenly.
- Step 3: Mix the butter and sugars
- In a large bowl, whisk together the melted butter, brown sugar, and granulated sugar until the mixture looks smooth and well combined.
- Allow the butter to cool slightly before adding the eggs. You don't want it hot enough to cook them!
- Step 4: Add the eggs and vanilla
- Whisk in the eggs, one at a time, followed by the vanilla extract.
- Mix until everything is combined and the batter looks glossy.
- The vanilla adds that classic bakery-style aroma that makes homemade cookie bars so inviting.Order Fresh Bakes
- Step 5: Add the dry ingredients
- Gradually stir the flour mixture into the wet ingredients.
- Use a spatula or wooden spoon and mix just until no dry streaks remain.
- The dough will be thick. That's exactly what you want!
- Avoid overmixing once the flour has been added, as too much mixing can make the finished bars tougher.
- Step 6: Fold in the chocolate chips
- Add the chocolate chips and gently fold them through the dough.
- If you're using chopped nuts or other baking chips, add them now too.
- Try to distribute the chocolate evenly so every square gets its fair share.
- Step 7: Spread the dough into the pan
- Transfer the dough to the prepared baking pan.Get Fresh Dairy
- Use a spatula or lightly greased hands to press it into an even layer, reaching the corners.
- The dough may feel thick and a little sticky, so take your time spreading it out.
- For an extra chocolatey finish, sprinkle a small handful of chocolate chips over the surface.
- Step 8: Bake until golden
- Bake for approximately 25–32 minutes, checking toward the lower end of the range.
- The edges should look golden, and the center should appear set rather than wet. A toothpick inserted into the center may have a few moist crumbs attached, but it shouldn't come out coated in raw dough.
- Remember that the bars will continue to set as they cool.
- Don't wait until the center looks completely dry, or you may lose that lovely chewy texture.
- Step 9: Cool before slicing
- Remove the pan from the oven and place it on a cooling rack.Order Sweet Treats
- Let the bars cool in the pan for at least 30–45 minutes before slicing. For the neatest squares, allow them to cool completely.
- I know, waiting is the hardest part!
- But cutting too soon can make the bars crumble or cause the melted chocolate to smear. A little patience gives you much prettier slices.
- Step 10: Slice and serve
- Lift the cooled bars out using the parchment paper, then cut them into 16 squares or your preferred size.
- Serve them as they are, warm them slightly before serving, or pair them with a scoop of vanilla ice cream.
- And if a few crumbs remain on the cutting board? Consider that the baker's reward!
- Tips for the Best Congo Bars
- Measure the flour correctly
- Too much flour can make the bars dry and dense. For the most consistent results, weigh the flour if you have a kitchen scale. Otherwise, spoon it lightly into your measuring cup and level off the top instead of packing it down.Find Recipes
- Don't overmix the dough
- Once the flour goes in, stir only until everything comes together. Overmixing can develop too much gluten and make the bars less tender.
- Use room-temperature eggs
- Room-temperature eggs blend more easily into the butter-and-sugar mixture, helping create a more uniform dough.
- Don't overbake
- This is the secret to chewy Congo Bars!
- The edges should be golden and the center should look set but still soft. If you bake them until the middle is completely firm, the bars may turn dry as they cool.
- Let them cool before cutting
- The center continues to set after the pan comes out of the oven. Cooling helps the bars hold their shape and gives you clean edges.Shop Candy Gifts
- Want a deeper flavor?
- Try dark brown sugar, a mixture of semisweet and dark chocolate, or a small sprinkle of flaky sea salt on top.
- That sweet-and-salty combination is wonderful!
- What to Serve With Congo Bars
- Congo Bars are delicious on their own, but they're also easy to turn into a more special dessert.
- Here are a few serving ideas:
- Cold milk: A classic pairing that balances the sweetness.
- Coffee or espresso: Perfect for an afternoon treat.
- Vanilla ice cream: Serve a slightly warm bar with a scoop on top for an easy dessert.
- Fresh berries: Strawberries or raspberries add a bright, fruity contrast.
- Hot chocolate: An especially cozy pairing on a chilly evening.
- Caramel sauce: Drizzle a little over the bars when serving them as a plated dessert.
- Order Fresh Bakes
- For parties, arrange the squares on a simple serving platter. A mixture of larger squares and bite-sized pieces makes the tray look generous and gives guests options.
- How to Store Congo Bars
- Once the bars have cooled completely, store them in an airtight container at room temperature.
- They generally stay soft and tasty for about 3–4 days, provided they're stored in a cool, dry place.
- To keep them from sticking together, place parchment paper between layers.
- Can You Refrigerate Congo Bars?
- You can, but refrigeration may make them firmer and less chewy. Room-temperature storage is usually best if you plan to eat them within a few days.
- If your kitchen is very warm, refrigerating them can help keep the chocolate from becoming too soft.
- Let refrigerated bars sit at room temperature briefly before serving for a softer texture.
- Can You Freeze Congo Bars?
- Absolutely! Congo Bars freeze well, making them a handy dessert to prepare ahead.Order Sweet Treats
- Let the bars cool completely.
- Slice them into squares.
- Wrap individual portions or layer them in a freezer-safe container with parchment between the layers.
- Freeze for up to about 3 months for best quality.
- Thaw the bars at room temperature before serving. You can also warm one briefly in the microwave if you'd like the chocolate to soften.

- Frequently Asked Questions
- Are Congo Bars the same as blondies?
- They're very similar, but not every recipe is identical. Congo Bars are often made with chocolate chips and have a texture closer to a thick chocolate chip cookie. Blondies can be more brownie-like, with a dense, fudgy texture and a strong brown-sugar flavor.
- The names sometimes overlap, depending on the recipe.
- Why are my Congo Bars dry?
- The most common reasons are too much flour or overbaking. Measure the flour carefully and remove the pan when the edges are golden and the center is just set.
- Remember, the bars continue to firm up as they cool.
- Why are the middle bars still soft?
- The center often remains softer than the edges, which is part of what makes these bars so delicious. However, it shouldn't look wet or contain raw dough.
- If the middle is genuinely underbaked, return the pan to the oven for a few more minutes and check again.Order Fresh Bakes
- Can I make Congo Bars without a mixer?
- Yes! A whisk and sturdy spatula are all you need. In fact, mixing by hand makes it easy to avoid overmixing the flour.
- Can I make the dough ahead of time?
- You can prepare the dough and refrigerate it briefly before baking, although chilled dough may take longer to spread evenly in the pan. For the easiest make-ahead option, bake the bars completely, cool them, and store them in an airtight container.
- Can I double the recipe?
- Yes, but use appropriately sized pans rather than making the dough excessively deep. Baking time will depend on the pan dimensions and thickness of the dough, so check for golden edges and a set center rather than relying on time alone.
- Can I use a different pan size?
- A smaller pan will make thicker bars and may require a longer baking time. A larger pan will make thinner bars that bake faster. For the most reliable results, use a 9-by-13-inch pan.Find Recipes
- How do I get clean, even squares?
- Let the bars cool completely, lift them from the pan using the parchment overhang, and cut them with a sharp knife. Wipe the blade between cuts if melted chocolate begins to build up.
