Growing up every year for my birthday my mom made me the same cake, Chocolate with Vanilla Icing in a rectangle dish. She made some sort of chocolate cake from a box (most likely Betty Crocker) and made an icing with powdered sugar and milk. I didn't really like frosting very much back then (I know crazy!), so my brother and I would trade – I'd give him my frosting and he'd give me his cake. 

I've learned so much about cake since those days. I know a birthday cake can be more than just chocolate cake with vanilla icing, and frosting has grown on me. I still eat it sparingly, but now I definitely feel like I can't eat cake without frosting.

This simple recipe just uses one bowl, which means you can use a stand mixer with a paddle attachment, a hand mixer, or even a bowl with a wooden spoon. However you want to mix this baby up, this One Bowl Chocolate Cake comes together with ease. Have your cake and eat it too with the best ever One Bowl Chocolate Cake recipe!

Can I use another type of oil?

Yes, if you want to use avocado oil or olive oil in this cake, you can do that as well!

Can I use vanilla extract instead of vanilla bean?

Yes, you can, but vanilla bean really gives this cake the best flavor! If you can get it, I highly recommend it. You can buy the organic ground vanilla bean I use here. But, if you want to use vanilla extract, you’ll need to add a little bit more as vanilla bean is stronger in flavor. If subbing to vanilla extract use 1 tablespoon of vanilla extract in the cake.

What else can I add on top?

You could add chocolate sprinkles instead of rainbow if you prefer. You can also add fresh fruit on top such as strawberries, blueberries, blackberries, or raspberries, they would all be delicious! You can also add Caramel Sauce on top or even a drizzle of Chocolate Ganache. Or feel free to add some nuts such as peanuts, pecans, or almonds. This is really a simple chocolate and vanilla cake, so anything you think would be good, probably would be good!

How should I store this cake?

This cake is moist and fluffy! So it should be stored in an airtight container to retain that perfect texture. After you bake and cut into the cake, you should cut the rest of it into pieces and put in tupperwares or a cake dome to keep them fresh! Or alternatively, you could wrap each one in plastic wrap. I don’t love that as it’s not as good and it’s also not very eco friendly, but it’s better than wasting the cake!

You all know I’m a huge organic advocate. And I bet you may be thinking sometimes, Why would I even bother to use organic ingredients in something that is so sweet and indulgent? But, that is the exact reason why you should use organic ingredients! Sweet things need to have flavor in order to be good. Otherwise they are just sweet and they don’t taste like much else.

Organic ingredients are more pure than conventional ones. Therefore they actually have more flavor than the non organic options. And organic ingredients are much healthier for you to eat in general as they do not contain GMOs or anything artificial. Additionally, you are being environmentally friendly when you choose organic ingredients!

So, I highly recommend that you buy the best organic ingredients for this recipe! I linked all the exact ingredients I used when making this recipe in the Ingredients section. You can also shop my Amazon Storefront for all my favorite organic ingredients here. Tip — hover over each ingredient to see the name.
