Combine in a skillet over medium low heat:
1 stick butter
1/2 c. corn syrup (I use simple syrup from binder)
1/2 c. milk
1 c. brown sugar
1 tsp. vanilla
Heat and stir until melted and smooth. Add in:
sliced bananas (as many as you want)
Try not to eat it all with a spoon! ;) Keeps well in the fridge if you eat all the bananas first time around.
