Chocolate Texas Sheet Cake

Since Labor Day is not too far away, I thought I'd share this recipe with you all.  I grew up with this one, and it's an easy cake to make, and makes for a great dessert for a 'bring a dish to pass' type gathering.  When I take it to our neighborhoods party, I just leave it right in the sheet cake pan.  That way it's easy to carry, cut, and share.  If you're a chocolate cake lover, you'll really love this one!
