Grandma's Chocolate Texas Sheet Cake


This Texas sheet cake is hands down my all-time favorite cake! I fell in love with making it after my grandmother shared the recipe with me. This dessert is super quick, easy, and fun to make. I definitely recommend this for first-time bakers and anyone else who would love to take a bite out of a delicious chocolate treat.
