Introduction
There’s nothing quite like the disappointment of pulling a batch of brownies out of the oven, only to find that they’re burnt on top and still raw in the middle. You’ve followed the recipe to the letter, but somehow, the top is overcooked while the center remains gooey and underbaked. This common baking issue can be frustrating, but the good news is that it’s entirely preventable with the right techniques and adjustments.
Understanding why this happens and how to fix it is key to achieving the perfect brownies every time. In this comprehensive guide, we’ll explore the causes of burnt tops and raw centers in brownies and provide you with practical solutions to avoid these problems. Whether you’re an experienced baker or just starting, these tips will help you master the art of brownie baking.
1. Common Causes of Burnt Tops and Raw Centers
1.1 High Oven Temperature
One of the most common reasons why brownies burn on top but remain raw in the middle is an oven temperature that’s too high. When the temperature is too high, the outside of the brownies cooks much faster than the inside, resulting in a burnt top and an undercooked center.
Why This Happens:
- The high heat causes the sugars in the brownie batter to caramelize quickly on the surface, leading to a burnt top. Caramelization, which happens when sugars in the batter start to break down, can occur too rapidly at high temperatures, creating a hard, burnt crust.
- Meanwhile, the center of the brownies hasn’t had enough time to cook through, leaving it raw and gooey. The interior, insulated by the outer layers, doesn’t reach the necessary temperature in time to bake fully.
Solution:
To avoid this issue, lower the oven temperature by 25°F (about 15°C) and extend the baking time. This allows the brownies to bake more evenly, giving the center time to cook without burning the top. Additionally, using an oven thermometer can help ensure your oven is calibrated correctly, as many home ovens can run hotter than their set temperature.
For those who frequently encounter this issue, consider using a convection setting if your oven has one. Convection ovens circulate hot air more evenly, which can help bake the brownies uniformly without scorching the top.

1.2 Incorrect Pan Placement
Where you place your pan in the oven can significantly impact how your brownies bake. Placing the pan too close to the heat source, such as the top heating element, can cause the top to overcook before the center has a chance to set.
Why This Happens:
- When the pan is too close to the top heating element, the intense heat can cause the surface of the brownies to bake too quickly. The direct heat from the top element is too strong for the batter, especially for recipes that require longer baking times, like brownies.
- This rapid baking on the surface doesn’t give the center enough time to rise and cook evenly. The result is an undercooked center, as the heat hasn’t penetrated deep enough into the batter.
Solution:
Position your brownies on the middle rack of the oven. This allows for more even heat distribution, reducing the risk of burning the top while the center remains raw. If your oven has hotspots, rotating the pan halfway through the baking process can also help ensure that the brownies bake evenly.
Another consideration is to use a baking stone or place a second, empty baking sheet on the bottom rack to act as a buffer between the heat source and your brownies. This technique can help reduce the direct impact of heat on the top and bottom of the brownies.
1.3 Overbaking on Top
Overbaking the top of your brownies while leaving the center undercooked often occurs when you don’t monitor the brownies closely during the final stages of baking. Even a few extra minutes in the oven can make the difference between perfectly cooked brownies and burnt ones.
Why This Happens:
- The sugars on the top of the brownies continue to cook and harden, leading to a burnt crust. This is particularly common with recipes that include a lot of sugar or chocolate, which can scorch easily at high temperatures.
- The middle, which cooks more slowly, may not have reached the desired temperature, leaving it raw. This imbalance is often due to the difference in heat exposure between the outer and inner parts of the batter.
Solution:
Start checking your brownies for doneness about 5-10 minutes before the recommended baking time is up. Use a toothpick or cake tester to check the center of the brownies. If it comes out with a few moist crumbs, the brownies are done. Don’t wait for the toothpick to come out completely clean, as this might mean the brownies are overbaked.
Additionally, keep an eye on the brownie edges. When the edges begin to pull away slightly from the sides of the pan, it’s a sign that the brownies are nearing doneness.

2. Techniques to Achieve Even Baking
2.1 Adjusting Oven Temperature
As mentioned earlier, oven temperature plays a crucial role in baking brownies evenly. A temperature that’s too high can cause the top to burn while leaving the middle raw. However, beyond simply lowering the temperature, there are other strategies you can employ to ensure even baking.
How to Adjust:
- Lower the Temperature: Reducing the oven temperature by 25°F (about 15°C) can make a significant difference. This slower, more gentle heat allows the brownies to bake evenly, ensuring that the center cooks through without burning the top. For thicker brownies, you may even consider lowering the temperature by up to 50°F (about 25°C) to ensure that the interior has enough time to bake fully.
- Use an Oven Thermometer: Even if your oven has a built-in thermometer, it may not be accurate. An external oven thermometer can help ensure that your oven is at the correct temperature. Regularly checking your oven’s accuracy is important, as ovens can become less reliable over time.
Why This Works:
By lowering the temperature, you allow the entire brownie to bake at a consistent rate. This prevents the top from hardening too quickly and gives the center time to cook properly. Additionally, the slower baking process allows the flavors to develop more fully, resulting in richer, more delicious brownies.
2.2 Monitoring Baking Time
Baking time is just as important as oven temperature when it comes to ensuring that your brownies are cooked evenly. Overbaking is a common culprit behind burnt tops, but underbaking can leave your brownies raw in the center.
How to Monitor:
- Set a Timer: Always set a timer when baking, and check the brownies about 5-10 minutes before the end of the recommended baking time. Consider setting two timers: one for the initial check and one for the final baking time.
- Perform the Toothpick Test: Insert a toothpick into the center of the brownies. If it comes out with a few moist crumbs but no raw batter, the brownies are done. If the toothpick comes out covered in wet batter, they need more time. On the other hand, if it comes out completely clean, they may be overbaked.
Why This Works:
By closely monitoring the baking time, you can pull the brownies out of the oven at the perfect moment, preventing the top from burning while ensuring the center is fully cooked. It’s also worth noting that baking times can vary depending on the thickness of the batter, the type of pan, and even the humidity in your kitchen. Adjust your baking time accordingly to achieve the best results.
2.3 Proper Pan Placement
The placement of your pan in the oven can greatly affect the final outcome of your brownies. Improper placement can lead to uneven baking, with the top burning and the center remaining raw.
How to Place the Pan:
- Middle Rack: Always place your brownies on the middle rack of the oven. This ensures that the heat is distributed evenly around the pan, reducing the risk of burning the top. For those who bake frequently, it might be helpful to keep a rack in the middle position at all times to ensure consistency.
- Avoid the Bottom Rack: Placing the pan on the bottom rack can cause the bottom of the brownies to cook too quickly, leading to a burnt bottom and an undercooked center. Additionally, using a baking sheet underneath the brownie pan can act as a buffer, preventing the bottom from getting too much direct heat.

3. Troubleshooting Tips
3.1 Covering Brownies with Foil
If you notice that the top of your brownies is cooking too quickly, covering them with foil can help protect the surface while the center continues to bake. This method is particularly useful for longer-baking brownie recipes or those with thicker batters.
How to Use Foil:
- Cover Midway Through Baking: About halfway through the baking time, cover the brownies loosely with aluminum foil. This will shield the top from direct heat, allowing the center to catch up. Make sure the foil is not tightly wrapped around the pan, as this can trap steam and affect the texture of the brownies.
- Remove the Foil in the Final Minutes: For a perfectly crisp top, remove the foil during the last few minutes of baking. This allows the top to finish cooking without burning.
Why This Works:
Foil acts as a barrier that prevents the top of the brownies from burning while the inside finishes cooking. This technique is especially useful if you’re using a pan that conducts heat unevenly or if you’re baking in an older oven that doesn’t distribute heat consistently.
3.2 Using the Right Pan
The type of pan you use can have a significant impact on how your brownies bake. Choosing the wrong pan can lead to uneven heat distribution, resulting in burnt tops and raw centers.
Choosing the Right Pan:
- Light-colored Metal Pans: These pans are ideal for baking brownies because they distribute heat evenly and reduce the risk of burning the top. Light-colored pans reflect heat, which prevents the edges from overcooking while the center is still baking.
- Avoid Glass and Dark Metal Pans: Glass and dark metal pans retain heat longer, which can cause the brownies to overcook on the top while the center remains undercooked. If you must use a dark pan, reduce the baking temperature by 25°F (about 15°C) to compensate for the more intense heat absorption.

3.3 Checking Brownie Doneness
Knowing when your brownies are done is crucial to preventing them from burning on top while remaining raw in the middle. However, checking for doneness can be tricky, as brownies continue to firm up as they cool.
How to Check Doneness:
- Toothpick Test: Insert a toothpick into the center of the brownies. If it comes out with a few moist crumbs, they are done. If the toothpick comes out clean, the brownies may be overbaked, and if it’s still covered in wet batter, they need more time.
- Gently Shake the Pan: If the center jiggles, the brownies need more time. If it’s firm, they’re ready to come out. Be careful not to mistake a fudgy center for being underbaked; the brownies will continue to set as they cool.
In addition to these techniques, consider the cooling process. Allowing brownies to cool in the pan for at least 15-20 minutes can help ensure that the center sets properly. Once cooled, cutting into them too soon can also give the impression that they are undercooked, so patience is key.
4. Frequently Asked Questions (FAQ)
