Recipe Testing Brownies for a 9×13-Inch Pan
My crew and I made 15(!!!) check batches in our quest to excellent a brownie recipe developed for a 9×13-inch pan. This recipe is predicated off my reader-favorite recipe for severely fudgy home made brownies, but it surely wasn’t so simple as multiplying all of the components by 1.5x. (Or 1.44x, which is the precise quantity of extra space a 9×13-inch pan has in contrast with a 9×9-inch pan.)
Once I initially revealed that brownie recipe in 2017, I made it in a 9×13-inch pan. Nonetheless, the brownies have been a bit skinny; and over time, I switched to a smaller pan for thicker brownies. They’re glorious.
Nonetheless, I wished to revisit the recipe and correctly scale it up as a result of typically we simply want a big batch of home made brownies! The aim right here was to successfully scale up that recipe with out dropping what makes it particular: an intensely fudgy texture with wealthy chocolate taste. Brownies can shortly flip cakey in a bigger pan if there’s an excessive amount of flour or not sufficient fats. Nonetheless, these hold the identical wealthy consistency as a result of we use:
- Melted chocolate and cocoa powder
- Melted butter and oil for taste + moisture
- Each granulated and brown sugar
- Equal components flour and cocoa powder
The end result? Massive-batch brownies with chewy edges, melt-in-your-mouth middles, and that signature tissue-thin shiny crackly prime. Perfection.

Key Substances You Want
- Principally butter with a contact of oil: There isn’t a query about it… butter gives the very best taste in brownies. Nonetheless, in our many rounds of testing, the bigger pan of brownies stored popping out barely dry. Lastly, we swapped a little bit of the butter for oil, which is what makes for additional moist chocolate cake. The second we tasted that batch, we knew we’d discovered the answer.
- Chocolate: You want 4 ounces (1 commonplace bar) of both semi-sweet or bittersweet baking chocolate. Chop it up and soften it with the butter.
- Sugar and brown sugar: Sugar does rather more than sweeten brownies. It liquifies as they bake, making a softer heart, and migrates to the highest, creating that shiny, crackly floor attribute of an excellent brownie. The unique home made brownies recipe makes use of all white granulated sugar, however our bigger batches weren’t fairly candy sufficient. Additionally they tasted a bit dry. So, we swapped a few of the white sugar for brown sugar, which has extra depth of taste. As a bonus, it gives additional moisture as nicely!
- Eggs, plus 1 egg yolk: Eggs are probably the most essential components in brownies. They bind, add richness, and supply construction. To correctly scale up the recipe, and to maintain such a big batch of brownies chewy and moist, we discovered 1 additional egg yolk is crucial. You want 4 complete eggs, plus 1 extra yolk.
- Dutch-process cocoa powder: Although pure cocoa powder can be utilized, I strongly recommend a Dutch-process cocoa powder (I actually like this model) for a richer, smoother chocolate taste.
- Chocolate chips: It’s possible you’ll suppose these brownies have sufficient chocolate already that you can miss the chocolate chips, however these aren’t elective! They assist bulk up the batter so the brownies are thick, plus they assist create an ultra-rich, moist brownie texture.
You additionally want flour, vanilla extract, and salt.
Useful Recipe Notes
- Heat melted chocolate and butter are the bottom of this recipe. Heat components assist to dissolve the sugar, which helps stop grainy brownies.
- This recipe requires an electrical mixer, both handheld or stand. You’ll use it to whip the eggs (and extra egg yolk) with the sugars. Whipping these components is the key to a shiny, crackly, tissue-thin brownie prime. As you beat them, the sugar begins dissolving into the eggs whereas air incorporates into the combination, creating construction and quantity. Then within the oven, the warmth continues dissolving the sugar and kinds that delicate shiny crust brownies are well-known for. Whip till the combination reaches the ribbon stage: pale yellow, thickened, and nearly custard-like in consistency.
- Don’t skip parchment paper. Line your 9×13-inch pan for straightforward removing and clear slicing.

Why Is It Referred to as the Ribbon Stage?
Should you cease whipping and carry the beaters or whisk attachment up out of the bowl, the combination ought to fall in a steady stream that creates a path of folded ribbon traces on the floor that stay seen for 10–30 seconds earlier than they disappear again into the combination. King Arthur Baking has a useful article about this, for those who’d like some extra data and visuals.
Add the melted chocolate/butter to the whipped eggs and sugars, then add the oil and vanilla:

Sift within the dry components, after which fold within the chocolate chips. Anticipate a thick batter:


The Greatest 9×13-Inch Pan for Brownies
I strongly suggest utilizing a light-colored metallic baking pan for brownies. Metallic pans conduct warmth shortly and evenly, which provides essentially the most constant texture and bake time. Keep away from dark-colored metallic for those who can; they will warmth the brownies too shortly.
Glass pans warmth slower AND retain warmth longer, so brownies are inclined to take longer for the facilities to bake by way of, whereas the sides over-bake.
Follow a silver metallic pan for brownies—like this one or this one.
The right way to Inform When Brownies Are Completed Baking
This may be tough, so right here’s methods to decide when these brownies are finished:
- Set the timer to half-hour as quickly because the brownies go into the oven.
- Stick a toothpick within the heart and pull it out. If the toothpick comes out thickly coated in moist batter, the brownies want extra time.
- Proceed to examine the brownies with a brand new toothpick each 2 minutes. If moist crumbs are clinging to the toothpick, the brownies are finished. You don’t need a clear toothpick—that may imply your brownies are overbaked and is perhaps dry. 32 minutes is essentially the most these brownies have ever taken in my oven (if utilizing a light-colored metallic baking pan).

Now comes the exhausting half: ready for the brownies to chill fully earlier than slicing them. I do know, it’s torture! However absolutely cooled brownies slice rather more cleanly and develop a fair fudgier texture. Should you want a brownie recipe you possibly can dig into straight away, do this skillet brownie!
An excessive amount of flour often causes cakey brownies. You should definitely weigh or spoon and degree your flour and cocoa powder so that you don’t unintentionally overmeasure.
Completely! Fold in 1 cup chopped walnuts or pecans with the chocolate chips.

You’ll be able to, however brownies baked in glass pans usually take longer and may flip overly chewy and hard across the edges. See the part above on the very best pan to make use of for brownies.
You may use a whisk as an alternative, however it would take some arm muscle and an extended time of vigorous whisking to get the eggs and sugar to achieve ribbon stage. I like to recommend an electrical hand mixer or stand mixer with a whisk attachment.

Description
Developed particularly for a 9×13-inch pan, this recipe yields a big batch of chewy, fudgy, wealthy bakery-style brownies which are excellent for sharing.
- Preheat the oven to 350°F (177°C) and line a 9×13-inch metallic baking pan with parchment paper, leaving an overhang to carry out the completed brownies (makes slicing simpler!). Put aside.
- In a small microwave-safe bowl or liquid measuring cup, mix the butter and chopped chocolate. Soften in 30-second increments, stirring after every, till fully melted and clean. Put aside to barely cool whilst you proceed.
- In a big bowl utilizing a handheld or stand mixer fitted with a whisk attachment, mix the granulated sugar, brown sugar, and eggs. Beat on medium-high velocity till the sugar begins to dissolve and the combination is pale and ribbon-y, about 4 minutes.
- Pour the nice and cozy melted butter/chocolate into the bowl with the sugar/egg combination, add the oil and vanilla, and beat or whisk to mix.
- Utilizing a advantageous mesh sieve, sift the flour, cocoa powder, and salt into the batter, then whisk or beat on low velocity till mixed. Fold within the chocolate chips. The batter shall be very thick. Unfold evenly into the ready pan. (A small offset spatula is useful right here.)
- Bake for half-hour, then check the brownies with a toothpick. Insert the toothpick into the middle of the pan. If the toothpick is totally coated in moist batter, return the brownies to the oven for two extra minutes. If the toothpick comes out with moist crumbs clinging to it, the brownies are finished. Err on the aspect of under-baking, because the brownies will proceed to set as they cool. (A very clear toothpick means the brownies are over-baked!)
- Take away from the oven and place on a cooling rack to chill fully within the pan. When cool, carry the brownies out by utilizing the parchment overhangs and switch to a slicing board. Use a pointy knife to chop into squares.
- Cowl and retailer leftover brownies at room temperature for as much as 1 week.
Notes
