Cranberry Buttermilk Cake

I don't seem to have luck on cake these days. This cake recipe was posted with a very appealing picture attached, which I decided to bake the moment I saw the picture. But my cake was not as good as I expected. The top was very nice hot from the oven. After rest for a night, the cake was dry and hard, like a scone. I still ate it with my cranberry sauce, but it fails the name of cake.
