I LOVE LOVE LOVE this cake - especially just eating the icing! It was my mother's grandmother's recipe, Lizzie Snow Gould.
Make it with classic yellow cake, two 9" cake circles. Make sure they are fully cooled before making the icing.
3 c sugar
1 c whole buttermilk
1 t baking soda
1 stick butter
Caramelize ½ c of the 3 cups of sugar. Do this by pouring sugar into a 3-4-qt saucepan (medium size), use very low heat and increase heat as you go, all the while stirring with a spoon or whisk to keep the sugar from sticking to the pan. This part takes a while. It will be getting close when the sugar starts to look and feel wet. Keep stirring and let it all change texture to the wet, syrupy sugar (clear in color).
Add ¼ c boiling water to the caramelized sugar, stand back!. You will be thinking at this point that you have messed up! All of the caramelized sugar turns hard as a rock in the boiling water, stir up all the hard pieces.
At this point pour the other ingredients into mixture and stir over medium to medium-high heat. Get it to a slow boil.

Cook until it forms a good ball when dropped in a glass of cold water. (Reach "soft ball" stage on candy thermometer, ~130 - 140 degrees F.) Remove from heat. Stir until creamy. It must be cool and creamy to go onto cake. It will go on the cake runny and harden on the cake. If you let it cool too much, it will be tough to spread onto cake (but still be delicious).
YUMMMM
btw - I completely photoshopped embellished my first picture. Here is the real final cake. Sometimes delicious doesn't equal pretty!
