Sheet Pan Brownies

Do you ever need to bake brownies for a crowd? Do you get tired of baking batch after batch? What if we could simplify your life and you could make one great big batch of brownies in your half sheet pan? Well, now you can!

Perfect for large family gatherings and cake stalls, not only does this sheet pan brownie recipe produce a lot of brownies, it’s also more economical than traditional, made from scratch brownies. Traditional brownies are full of chocolate, this sheet pan brownie recipe uses cocoa powder instead of chocolate which is much friendlier on the budget!

This recipe also couldn’t be any easier – melt some butter and mix it all together, spread it in your half sheet pan and you’re done!

We used our Stainless Steel Half Sheet Pan for this recipe because it makes wash up a breeze – it’s dishwasher safe! You could also use our Aluminum Half Sheet Pan and get the same results – but you’ll need to wash the pan by hand. We wouldn’t recommend cheap stainless steel half sheet pans as they don’t use the same technology to prevent them from warping as the Checkered Chef Stainless Steel Pans – you could end up with a very messy oven if your pan warps and brownie mixture spills everywhere.

Preheat your oven to 350℉ or 180℃

Lightly grease your half sheet pan with cooking spray or a bit of melted butter.

Melt your butter, either in a saucepan or in the microwave. We used the microwave as it’s quick and easy and the microwave-safe jug can just go straight in the dishwasher.

Put cocoa, eggs, salt and baking powder into the bowl of a stand mixer (or large bowl that you can use a handheld mixer in).

Mix to combine.

Add melted butter, sugar and vanilla.

Mix a bit more.

While the mixer is running gradually add in the flour and the cinnamon. You don’t need to use cinnamon, we just think it helps to bring out the chocolate flavor of the cocoa. Also, I once read that cinnamon is good to help control your blood sugar levels so I like to add it when I can – leave it out if you’re not keen or don’t have any.

Use a spatula or spoon to mix through some chocolate chips (if using). We used a mixture of white and milk chocolate chips.

Spread mixture into prepared baking sheet.

Bake for 35 minutes.

The mixture does expand and it will come out with a kind of ripple effect like a stone was thrown in a puddle. That seems to give it its crunchy exterior while the center is soft and chewy!

Allow it to cool in the pan before cutting into serving-size pieces.
