Warm your milk and shortening on the stovetop on very low until shortening is melted; turn off heat.
Mix flour, salt, baking powder with milk mixture until dough forms. Roll out to 1/2 inch thickness and cut with biscuit cutter. (I use an upsidedown cup.)
Cut each biscuit into 4 pieces. Toss them in dry cinnamon & sugar mix.
Drop biscuit pieces into greased bundt pan until bottom is covered. Slice 1 banana and cover biscuits with banana pieces. Create another layer of biscuit pieces, another layer of the 2nd banana and so on.
Mix melted butter with cinnamon and sugar until it's very thick. Pour into bundt pan over biscuits & bananas. Bake for 20-30 minutes.
NOTE: Put a pan under your bundt pan - it bubbles over a little! This turns out amazing. My family devoured the whole thing! Thank you Jesus for baking with me :0)
