Yes, you can certainly double or even triple this Chocolate Oatmeal Cake recipe. Use a larger baking dish and adjust the baking time if necessary. Ensure the batter is evenly spread out in the dish.

why didn’t my oatmeal cake puff up?

When using baking powder, always check the expiration date. Expired baking powder will not help your recipe rise in the oven, and you’ll have a sad, deflated cake.

I started to really cook and experiment with food 11 years ago when I was 21 years old. Everything I currently know is a reflection of some part of my life…
