I briefly looked into why this is called Texas sheet cake but there was no evidence to where or when this originally got it’s name that I could find. I did share this recipe a few years ago but I thought it needed to make another appearance. 
I honestly do not care what it is called or where it came from but thank you to whoever started it. It is very moist, tangy, chocolaty, easy to make and just plain delicious! I strongly suggest you make this cake at least once in your life, though if you do, you will be making it again!
The only ingredient that I needed to grab from the store was buttermilk. I do wish I could find a pint of buttermilk but all I have ever seen is it by a quart. Since I don’t love wasting food I will find some other uses for it, like buttermilk pancakes, buttermilk biscuits or buttermilk fried chicken. I was actually thinking of trying to make an Irish Soda Bread since this weekend it St Patrick’s Day and I have never made it before.

I usually make this cake in one sheet pan and add nuts but I was invited to friends for dinner and wasn’t sure how the nuts would go over and I wanted to make it a little festive so I added green and white sprinkles. I used two sheet pans just cuz no reasoning. I hope everyone likes it!
