Turn the Crock-Pot on high, and place the stick of butter in the crockpot to melt. When the butter melts, open the cans of Grands Biscuits, and cut the Biscuits in 4ths. Place the Biscuit pieces in the crockpot, and stir well, coating the Biscuits in the Butter. Cook the Biscuits for about 2 hours, stirring about every 20 minutes, and turning the biscuits in the crockpot so all the biscuits brown, and cook through.
When the biscuits are done, peel one of the Banana and place it in a Blender or Food Processor. Add the Sweetened Condensed Milk, and half n half and pulse to blend. Add the Instant Pudding, and pulse to mix well. Pour the Banana cream filling over the cooked Biscuits in the crockpot, and stir well to mix. Turn the Crockpot on low, and cook for 30 minutes. Turn off the Crock-Pot, and make the Icing.
In the Blender or Mixer, place a ripe Banana, and mix well to mash. Add Cream Cheese, Vanilla, and Milk, and mix until smooth. Add Powdered Sugar a little at a time until well blended. Scoop out servings into bowls, or dessert plates, and spoon Icing over servings. Top with whipped cream, and sliced bananas. Enjoy!
