Cardamom Chocolate Sheet Cake is a decadent cake perfect for any occasion!

I say this with all seriousness.

Chocolate Sheet Cake used to haunt my dreams.

Wait. How can a delicious, chocolate cake give one nightmares? Well, the answer is easy. You make said cake over and over for your spouses birthday and for some reason the cake self implodes, gives you the middle finger, and makes a splashy exit for the kitchen walls.

I’ve made many cakes, pies, and tarts in my day. BUT! For some reason every time I made a chocolate sheet cake, it turned into a hot mess with yours truly standing in the kitchen sporting huge crocodile tears.

I honestly don’t know what I was doing wrong. Maybe it was the sheet pan baking style that throws everything off? Or adding hot water to batter? Maybe I should have just stuck to box cakes? Or maybe I should have seen a cake therapist?

Anyway, given all the past drama with this cake, I finally decided to face my fears. In order to get my arms around this bad boy I knew I needed to create my own version. You know, put a little bit of me in the cake. Which is why I decided to add cardamom spice to the whole operation.

Cardamom and chocolate are like two best friends. The spice of cardamom ( a little goes a long way) elevates the cake to a sophisticated level in which you feel you could be enjoying a slice next to Harry and Meghan. Also, t-minus one month until they are married? WHO’S EXCITED?!!!

The rest of the ingredients in the sheet cake are the usual suspects. Simple, delicious, and I honestly think the cardamom gives the cake super powers and keeps the cake from trying to make a run for it while in the oven. Just sayin’.

Prevent cake nightmares and add the cardamom.
