Cookie Sheet Chocolate Cake

First off, to my followers, I am SO sorry I have not posted in forever.  Literally, forever.  I have gotten a few requests to start posting recipes again.  You see, I am pregnant with number 2 and food just has not been appealing to me lately, hence the no baking/cooking really.  But good news, I am back!  Or at least trying to be!  Haha!  So with out further ado, a new recipe! :)

This has been one of my favorite chocolate recipes since forever!  Whenever my mom would say, “I want something chocolate, what should I make?”  This was always the response.

Cookie Sheet Chocolate Cake from …This will quickly become one of your favorite cake recipes of all time! It is AMAZING!

    Isn't this the best cake?! It's the same recipe that my Mom gave me while I was growing up. I make it for my family all the time. We love it! I think it must be a Utah thing. :)

    growing up my mom always made this for large group cookouts. She added cinnamon and I was never much of a fan until one day I made it without the cinnamon! YUM. I think I will make it for after church tomorrow.. I haven't made it in years!

      can be any where from a 9×13 inch pan to a l0 x 15 inch.. when it is in the smaller pan it makes a thicker cake…

    this is a good & easy little ol cake.. In our area it is known as a Texas Sheet cake I like to add just a tsp of cinnamon.. Makes it taste so good…

    On the frosting you said one box of powder sugar could you tell me how many cups is that or size of box?
    Thank you!

    Add a little cinnamon to both the cake and icing and chopped pecans to the icing and you’d have a Texas Sheet Cake. That was the second cake I learned to make from scratch when I was 7 yrs old.
