Place dates in a bowl and cover with hot water then let stand and soften for 10 minutes.
In a food processor, add dates along with the water and pulse to begin to break down the dates. Then place food processor on low and blend until the dates have completely broken down and begin to thicken up, almost like a caramel. Then add the bananas, melted butter, egg, and vanilla extract. Once completely combined, add to a large bowl and slowly mix in the gluten free flour, baking soda, and salt.
Pour mixture into greased and lined bread pan.
Place in the oven and bake for 55 minutes to 1 hour or until a toothpick comes out clean from the middle of the loaf. After 30 minutes, take a piece of aluminum foil and place it lightly over the top of the banana bread to keep from browning too much. Once banana bread is cooked through, let stand for 10 minutes before removing from pan and then let cool on a rack. Serve warm with some butter and enjoy your life! Store in the fridge in a closed container.
