This Brownie Sheet Cake recipe is so good. It’s a mix between a brownie and chocolate sheet cake. Yum!
How about a little sweet temptation? Let me tell you how I came up with this Brownie Sheet Cake recipe.
A couple of years ago my youngest child had a math tournament and his school is hosted it. Parents were asked to bring some goodies for a concession sale. I thought that brownies should be a hit.
In looking through a lot of recipes, though, I realized that most recipes only make a 9×9 or an 8×8 pan. I wanted something bigger.
I combined some elements of a few recipes, tweaked them a little, and bam! Brownie Sheet Cake!
I started off by making a simple chocolate syrup. Just sugar, cocoa, water, vanilla, and a little salt.
I make the syrup first because it has to come to a boil and then cool. It will thicken some during the cooling period.
While the syrup was cooling, I got to work on other aspects of the brownies, like preparing my 9×13 pan
I then got all of my other ingredients together. (Above is flour, baking powder, salt, and espresso powder.)
Typically eggs are added one at a time. I like to crack all of mine into a little glass bowl. I then try to pour them in, one at a time.
The recipe has a mixture of cocoa powder, butter, and oil. This is quite bitter since there is no sugar. But that is okay since there are two cups of sugar in the brownie batter.
Luscious batter – still not ready
This is how it looks before the icing is added.
The icing is a simple chocolate glaze made with chocolate chips, butter, and a little corn syrup.

Brownie Sheet Cake
Brownie Sheet Cake - this dessert recipe is so good. It's a mix between a brownie and chocolate sheet cake. Yum!
Ingredients
Chocolate Syrup
- ¼ cup unsweetened cocoa powder
- ½ cup water
- 1 cup sugar
- 1 tsp vanilla
- ¼ tsp salt
Brownie Batter
- 1½ cups all-purpose flour
- 1 tsp baking powder
- 1 tsp salt
- 2 Tbsp espresso powder
- 10 Tbsp butter
- ¾ cup baking cocoa
- ¼ cup vegetable oil
- 2 cups sugar
- 4 large eggs
- 2 tsp vanilla extract
- two-thirds cup chocolate chips
- Chocolate Syrup
Chocolate Icing
- 1¼ cups chocolate chips
- 3 Tbsp corn syrup
- 1 stick butter
Instructions
- To make the syrup: in a medium or large saucepan, whisk the cocoa powder and sugar until well blended. Add water and whisk over medium-high until it starts to boil and becomes a little frothy. Continue boiling for approximately 3 minutes. Reduce heat and allow to simmer for 2 more minutes. Remove from the heat and add salt. Let cool.
- Preheat oven to 350 degrees. Line bottom of 13x9 pan with aluminum foil and spray with non-stick cooking spray.
- Combine flour, baking powder, salt, and espresso powder and set aside.
- Microwave butter until melted in a medium size glass bowl. Add cocoa and oil and whisk until smooth.
- Transfer cocoa mixture to a bowl of an electric mixer. Stir in sugar. Add eggs, one at a time, mixing well after each addition. Add vanilla. Gradually add flour mixture. Pour in chocolate syrup and chocolate chips.
- Pour batter into prepared 13x9 pan and bake for 25-30 minutes or until done. Let cool before icing.
- To make the icing: Melt chocolate chips and butter together in a microwave-safe bowl in 30 second intervals on high, stirring well after each segment. (It took me a total of one minute + an additional 10 seconds.) Add corn syrup and stir until smooth. Let sit for 5 minutes before pouring over brownies.

Looks amazing. Can’t wait to try them. How much instant coffee instead of expresso?
Thanks
I would double the amount.
Would like to bake in a larger sheet cake pan would this work
I am not sure. If you were to do that, you would have to adjust the baking time and/or temperature.
I see the instructions to make the chocolate syrup, but no instructions as to what the syrup is for. Is it added to the brownie batter or just something to drizzle on top?
Look at step #5. It gets added to the batter to make it nice and chocolate-y. 🙂
I love this cake. It looks so amazing
I’d like to know about espresso powder, because here in Brazil there isn’t it.
Do you have instant coffee available?
What is a concession stand for food?
The “concession stand” was a room full of food that was available for parents of children who were competing in the competition. Parents of children at the host school were asked to bring goodies for the visitors.
im from the south and these have been touched! I love them
hola at your girl omg! These were awesome!

You must have been reading my mind because I couldn’t stop thinking about making brownies today! LOL.
Pinning!
Those look so moist and delicious!
Mmm that looks tasty! Anything chocolate and brownie is fine by me!
These remind me of those Little Debbie comic brownies. Love a good brownie!
I do NOT like chocolate. Not even the least little bit. BUT? I LOVE Brownies. LOVE THEM! Especially if they are fresh out of the oven, too hot to eat. YUM! And the crispier edges! Super-YUM!
What kind of chocolate chips did you use?
I cannot recall what brand, but it was more than likely either Nestle, Publix, or Kroger’s Simple Truth Organic chocolate chips.
What kind of chocolate chips did you use for the cake and icing?
Honestly, I don’t remember what brand, but it would probably have been Nestle, Publix brand, or possibly Kroger’s Simple Truth.
Hey just wondering if it would still be yummy without the espresso powder? I don’t have any in my house due to not drinking coffee or using it in anything. They just look so yummy I really want to try them!
I would imagine they should be fine without the espresso powder. If I did not have espresso powder I would still make them. The powder just helps to highlight the chocolate flavor.
That looks awesome! I’ve never put icing on brownies, but clearly should be. 🙂
Looks amazing. I love brownies.
This looks amazing. I would eat the whole sheet myself. lol.
My only question is are these cakey or fudgy? They look amazing!
I would say that they are a blend of the two, if that makes any sense. Thanks for stopping by.
Those are some good looking brownies. I never have much luck with them myself. Mine always end up hard and overbaked or soft and gooey/raw in the middle.
When do you add the stick of butter to the icing?
Thank you so much for catching that! Melt the butter with the chocolate chips in the microwave. (I went back and corrected the recipe.) 🙂
This looks great! I also have to make some concession stand food in a couple of weeks. Maybe I’ll try your recipe.
I can’t believe you didn’t offer to send me some of these. What kind of friend are you? 😉 Those look sooooooooo good!
I believe my family would gobble that up! I made some Turtle Brownies this weekend, the pan is almost empty, ha ha!
That looks utterly amazing! Thanks for the recipe. 🙂
That looks so decadent and delicious!
Now that’s the size of brownie recipe I needed! With a large family, this is perfect! Thank you!
Dang it! I really want some brownies now. Thanks for another great recipe that has me drooling.
OOoo how yummy! I bet my hubby would love this!
that looks SO rich!!
I should not of seen this before dinner. My tummy is grumbling! I love chocolate. 🙂
Anything with a stick of butter in it has to be good. Looks amazing!
Oh, these look so good! Can’t wait to try them!
Hello LOVER!!! This looks amazing!
Homemade brownies are delicious, I will have to try your recipe
OMG! This looks utterly amazing! My son makes something similar but I think he needs to add the syrup. I’m going to show him this.
Happy SITS Saturday Sharefest!
You had me at brownie but then you took it over the top! I might do this for my little guys 2nd birthday! Great idea. Thanks for sharing.

You just had to go there today. I was all good until I saw that brownie. Man that chocolate icing looks so good.
oh man! the chocolate looks so so so so good on the brownie!
That looks fantastic!
looks delicious….I love the way you tweak, mix and match your recipes!
Oh goodness..this looks heavenly!
This would be good without the icing. I love the crust on the brownies!
