1Toasted pecans in oven on a baking sheet until toasted about 10 minutes. Heat oven 375 degrees. Line 10x15 jelly roll pan or 13x9 pan with parchment paper. or butter the pans. I use parchment paper.If you use 9x13 pan the bars will be thicker like cake.
2Blend the sugar,sour cream,cream cheese,and eggs together until smooth.
3blend in bananas,and vanilla until incorporated.
4add flour,baking soda,salt with spoon. Mix well!!!
add pecans and stir until blended.
5put in to pan and bake for about 30 minutes at 375 degrees or until pick comes out clean.
6Time to make your frosting. You can frost cake while warm. It actually works better. If frosting is thick add a bit more milk to it,
7melt butter in sauce pan until golden brown.remove from heat. add confection sugar,vanilla and milk and stir until blended well. If frosting is thick add more milk until you get a smooth frosting.
8now frost cake while it is warm.if you use the 9x13 pan for the cake use less of the frosting. cool and cut in to bars. I eat one while warm! LOL Enjoy with a cup of coffee or tea.
