Banana Cake with Caramel Frosting

I AM BACK! I haven't posted much in a while and I am back and you will start seeing a lot more of me. :)
This recipe came from my friend Wendi. The frosting is the best and I could (and do) eat it with nothing but a spoon. I made this for our memorial day festivities and then left it home, so now I get to enjoy it all by myself. This is the only cake I know of that it is actually better to frost it when it is still a little warm... it just spreads better.

Banana Cake:
2 cups flour
1/2 tsp soda
1/2 cup shortning
1 1/2 cups sugar
2 eggs
2 ripe bananas
1/4 cup buttermilk
walnuts

preheat oven to 350 degrees. sift together flour and soda and set aside. mix shortning and sugar together until fluffy. then add eggs. mix together bananas, buttermilk, and vanilla and add them to the mixture. Finally add the flour mixture and the walnuts if desired. Grease and flour a cookie sheet. place batter in the pan and bake for 30-35 minutes

Caramel Frosting:
1/2 cup butter
1 Cup dark brown sugar
1/3 Cup cream
1 T vanilla
1 lb powdered sugar

In a saucepan, melt the butter and add the dark brown sugar and cream until the sugar is dissolved. Remove from heat and add the vanilla. Transfer to a mixer bowl and mix on low speed gradually adding the powdered sugar. You may need some extra cream to add to the frosting so it is the right consistency. Spread it on the cake when it is about halfway cool. Then try not to "accidentally" leave it home from the family picnic so you have to eat it all yourself.
