Cookie Sheet Chocolate Cake

by 247tasty

Our favorite and the best cake ever! I cannot count how many times I’ve made this cookie sheet chocolate cake. My kids are always craving for it, they love it so much they can finish the whole thing in one sitting. This cake has a velvety texture, it’s moist, has a thick frosting, fudgy, and very addictive! I always make this for my kids because they are crazy about it, just like me when I was their age. I remember my mom in the kitchen, so delighted while making this cake. Every bite of this scrumptious cake reminds me of my childhood and my mom. This is a keeper and surely a classic cake that’s worth passing on to generations.

Step 6: Combine the buttermilk and cocoa and bring to a boil.
