My brother -in-law, Isaac, is currently training for an ironman, and requested a cake with brownie layers and Oreo buttercream.
His lucky number is 5, and he jokingly said he’d like a five layer cake. Little did he know, his comment would result in a 20 lb, monstrosity of a cake 🙂
I baked the brownie layers first, the cake layers second, and while they cooled, I whipped up the Oreo buttercream. The recipe can be found below:
Double Chocolate Brownies
- 1.5 cups melted butter (3 sticks butter)
- 4.5 cups sugar
- 1 tablespoon vanilla extract
- 6 eggs
- 2 1/4 cup flour
- 1 1/2 cups cocoa powder
- 1 1/2 tsp salt
- 1 cup semi chocolate chips
- 1 cup dark chocolate chips
White Cake Base
- 1.5 cup (3 sticks) butter, softened
- 3 cups granulated sugar
- 5 eggs, room temperature
- 3 cups all-purpose flour
- 2 teaspoons baking powder
- 1/4 teaspoon salt
- 1 cup buttermilk, room temperature
- 1 tsp. espresso powder, dissolved in 1 tbsp hot water
- 2 teaspoons vanilla extract
- 4 sticks butter
- 8 cups powdered sugar
- 1 tsp. vanilla extract
- 20 oreos, chopped finely (reserve the rest of the pack for decorations)
- 1/3 cup heavy cream
- 1/2 tsp. salt
- 3/4 cup heavy cream
- 3/4 cup chocolate chips
woah! Five layers?! That’s amazing!
Hi. I’m interested in this cake for 5/2 . Is it possible?
Unfortunately I’m booked until the beginning of June, I’m so sorry!!
Am I reading on your five layer brownie Oreo cake four and a half cups of sugar .
yes! it has a lot of sugar and not a lot of flour, the recipe is kind of reminiscent to a flourless chocolate cake. It’s a lot of butter and eggs too – __ –
The espresso powder included in the white cake ingredients doesn’t appear to be in the actual directions. Should it be added with buttermilk and vanilla?
I’m so sorry, that was simply a typo! I’ve removed it from the ingredients list. I sadly wasn’t as thorough on my recipes when I first started my blog!!
This looks amazing!! Do you think it would work to cut the recipe in half? I’d like to make it for my fiancé’s birthday but it would just be the two of us eating it.

Hi Susie,
You should totally be able to cut this recipe in half! That’s so sweet of you, I’m sure he’s going to love it!
