Chocolate Sheet Cake
This chocolate sheet cake is everything a good chocolate cake should be, and more. It’s deliciously chocolatey, fudgy and most importantly, very quick and easy to make.

All you need to make this chocolate cake are two mixing bowls; no stand mixer required! It’s as simple as combining the dry ingredients in one bowl, the wet ingredients in another, then combining the dry and wet ingredients to get the deliciously chocolatey batter.

What makes a chocolate cake even better? A layer of thick and sweet chocolate icing. I recommend topping this chocolate sheet cake with my amazingly fluffy whipped chocolate buttercream. This part you will need a stand mixer for, but it’s well worth the few minutes of beating. This recipe makes a generous amount of buttercream, so if you find you have some leftover just place in the fridge in an airtight container for another day. Bring the buttercream to room temperature and it’s good to go.
Once you have spread a generous layer of buttercream over the cake, decorate the cake with plenty of colourful sprinkles. No-one is going to say no to a slice of chocolate cake topped with sprinkles!
