Banana Gateau

This is from the Joy of Cooking and it's pretty spectacular.  You can make it super glam like I did or in a single layer in a 9X13 pan with the caramel on top.

Banana Cake

Whisk together:

2 1/4 cups cake flour
3/4 tsp baking soda
1/2 tsp baking powder
1/2 tsp salt

Blitz in a food processor:

2 large ripe bananas
1/4 cup buttermilk
1 tsp vanilla

Cream in a mixer:

1 stick butter
1 cup + 2 tbsp sugar

Add:

2 eggs(one at a time)

Add the wet and dry mixture, alternating some of each until combined.  Spoon into a greased and papered 10X15 jellyroll pan and bake at  350 for 25 minutes.  Let cool.

Caramel Frosting

Combine in a saucepan:

4 cups brown sugar
2 sticks butter
1 cup cream
2 tbsp corn syrup

Cook to the soft ball stage.  Remove from heat and pour into a mixing bowl.  Float

6 tbsp butter

Let cool to 140 and start beating.  Add:

2 tsp vanilla

Beat until spreadable.  Don't let this get too cold or it will be hard to work with.


Assembly

Cut the cake in half and then split each of the layers to make four long thin layers.  Assemble the cake with caramel between three of the layers and nothing on top.  Refrigerate to firm it up.  Then trim the edges and dust with powdered sugar.  Bon appetit!
