If you're looking for a showstopper dessert, look no further than this amazing Brownie Cake! Three layers of fudginess can be made ahead individually, and the whole cake can be frozen.

I'm not a fan of cakey brownies at all.
The fudgier, the better. The proof is in these fudgy brownies, another recipe with three types of chocolate and my go-to recipe.
But today, this one benefits from a brownie that's not as dense or chocolate-laden. The two extra layers of ganache more than balance everything up.
If chocolate answers everything, this dessert is just what we all need.
Three layers of chocolate. Period.
A cakey, fudgy brownie base topped with a layer of white and dark chocolate ganache. By themselves they are good, together they are amazing.
Chocolate layers
Both layers on top of the brownie base are ganache made with two types of chocolate.
What is chocolate ganache?
It is a mixture of cream and chocolate.
Hot cream is poured over the chopped chocolate, usually dark, let rest a few minutes and then whisked to create a silky, creamy, shiny, delicious mixture.
It can be made with different ratios depending on your preference.
Step-by-step VIDEO
White chocolate is also used, but it doesn't appear shiny.
But it's very yummy, that I can tell you. Check out the White Chocolate Raspberry Bundt Cake for using it as a glaze.
Kitchen notes
- Make-ahead: the brownie base can be made ahead and kept at room t° for two days, refrigerated (well wrapped) for 4-5 days or frozen (well wrapped) for a month. So both ganaches. Keep refrigerated and slightly warm (in the microwave) until spreadable consistency.
- Storing: keep leftovers refrigerated, wrapped so that it doesn't dry out. Or freeze, well wrapped, for up to a month. Take out and let soften before serving. Or put it in the refrigerator the night before. Keep in mind that if refrigerated or frozen, it will not be as shiny.
- Nuts: add some walnuts to the brownie base, about ½ cup.
- Mint variation: the idea was to add mint to the white chocolate layer. So I tried it, and it blew my mind! So, if you're a chocolate mint fan, please use a teaspoon in the white chocolate ganache layer.
Serving
It is my strong opinion that chocolate cakes (regular or vegan) and chocolate desserts should be eaten the next day they are made. The flavor develops, and they are so much better, mellower but with a definite presence.
Also, I like to eat them at room temperature.
This brownie cake, in particular, is fine at room temperature unless your kitchen is too hot.
I never refrigerated it, and, as you can see, it cuts perfectly.

- Add the corn syrup, mix well and spread evenly over the cooled white layer.
- Let set at room tº if you want it to stay shiny.
- Take out from the pan carefully, using the parchment paper as an aid.
- Cut into squares and serve.
Notes
Make-ahead: the brownie base can be made ahead and kept at room t° for two days, refrigerated (well wrapped) for 4-5 days or frozen (well wrapped) for a month. So both ganaches. Keep refrigerated and slightly warm (in the microwave) until of spreadable consistency.
Storing: keep refrigerated, wrapped so that it doesn't dry out. Or freeze, well wrapped, for up to a month. Take out and let soften before serving. Or put in the refrigerator the night before. If refrigerated or frozen t will not be as shiny, keep that in mind.
Serving: I like to keep and serve at room t°. But it is good cold, just not as shiny.
Nuts: you can add some walnuts to the brownie base, about ½ cup.
Mint variation: there was the idea to add mint to the white chocolate layer. So I tried it and it blew my mind! So, if you're a chocolate mint fan, please use a teaspoon in the white chocolate ganache layer.
