I had some buttermilk in the fridge that I didn't want to go to waste. I picked up my Joy of Cooking and searched in the index for potential recipe ideas. I came across the layer buttermilk cake recipe and said that's what I'm going to make. I had just read a very short article in Saveur magazine about a buttermilk cake. Turns out this cake is super yummy, easy to make and I made sure to share it with my neighbors too.
