Instructions
Brownie Cake
- Preheat your oven to 400 degrees and grease a large baking sheet.
- Mix the flour, salt, baking soda, and sugar in a large bowl and set aside.
- Heat a saucepan over medium-high heat on the stove. Melt butter in pot.
- Once melted, add the cocoa powder and water and bring the mixture to a boil.
- Once boiling remove from heat and add the boiling chocolate mixture to the flour mixture from earlier and stir until well combined.
- Add buttermilk, eggs, and vanilla to the mixture and combine until you have a nice smooth batter. This can be done by hand or with a hand mixer.
- Pour the batter into the prepped baking sheet making sure to evenly spread it across the entire sheet pan.
- Bake cake in the oven for 20-22 minutes or until cake is cooked all the way through.
- While the cake is baking, make the icing according to the instructions below.
- Top the cake with icing within five minutes of removing the cake from the oven.
- Top with chopped walnuts if desired.
- Allow cake to cool completely then cut into squares and serve.
Icing
- In a medium, heat-safe bowl, measure out powdered sugar and set aside for later.
- Heat a pot over medium-high heat on the stove. Melt butter in pot.
- Add cocoa and milk to melted butter and bring to a boil.
- Put your powdered sugar into a small bowl then pour the boiled mixture over the powdered sugar and stir to combine to make your icing.

Notes
- Add the walnuts immediately after adding the icing rather than waiting until it hardens. This will keep the nuts from falling off when you slice the cake.
- Use a spatula to make sure that the chocolate brownie cake batter spreads around the entire sheet pan in one even layer.
- Leave the chocolate brownie cake in the pan rather than slicing it all and removing for storage. I recommend just covering it with something like this sheet pan lid.
- Remove the chocolate mixtures from heat as soon as they start boiling, don’t let them keep boiling or you’ll lose some of the moisture in the cake and icing.
- Use a small rectangle spatula to remove the cake squares from the pan without destroying the rest of the squares.
