Dessert Bar FAQs

There’s so much more to know about this go-to potluck dessert. Check out our answers to some of the most common questions.

Q: Is baking powder necessary for brownies?

A: Nope! Baking powder is a leavening agent. This means that when you add it to your brownie mix, it’ll produce a fluffier, more cake-like texture—kind of like these moist cake brownies. For more fudgy brownies, like these peanut butter marshmallow brownies, the baking powder is omitted to prevent the batter from getting puffed up.

Learn about the difference between baking powder and baking soda (because there is one).

Q: How do you know when a cookie bar is done?

A: Your bars should be set and slightly browned. Insert a toothpick in the center of the bars; if it comes out clean, they’re ready to be removed from the oven.

Q: Why aren’t my brownies cooked?

A: There are a few reasons your brownies might have not baked within the time listed on the recipe. The first could be that your oven isn’t getting up to the temperature you’re setting it to. Luckily, we have a handy guide for recalibrating your oven’s temp (and it’s really easy).

Another reason could be that you’ve used the wrong pan for the recipe. Glass pans take longer to heat up and cool down, so a good amount of heat may not reach the center of your batter, resulting in undercooked brownies. It’s best to use a dull, aluminum baking pan when baking these treats.

Over the years we’ve had many readers ask about the best pan for baking brownies, so we went ahead and developed a line that’ll help your desserts bake to perfection every time. Check out our 5-piece bakeware set.

Q: How many bars does a 13×9 pan hold?

A: About two dozen—but it really depends on how you large or small you cut the dessert. Take a look at our tips for cutting dessert bars like a pro (and know how many you’ll end up with).
