With summer right around the corner, it’s almost time for barbecues and pot-lucks. When we go to get-togethers like barbecues or pot-lucks, I almost always volunteer to bring a dessert because, so many times, the dessert gets overlooked.
I am particularly fond of bringing chocolate sheet cakes because they’re so easy to make. There’s no fancy frosting to fuss with, and it really doesn’t get much easier than cakes like this Rocky Road Chocolate Sheet Cake.
It makes a huge cake, which makes it great for big get-togethers, and it only takes about 30 minutes to make and ice it. So, it’s also perfect for those times when you have to hurry and make something last-minute.
This cake is based on my grandma’s chocolate sheet cake recipe. It’s my favorite chocolate cake recipe, and I think it’s hard to beat. If you try this easy, delicious cake, you just might find that it becomes a family favorite at your house, too!
