Whisk together the eggs, half and half, sugar, vanilla and cinnamon in a shallow bowl. Dip slices of banana bread in the mixture, coating on each side. Do not let the bread get too soggy, several seconds on each side should do. Set aside in a dish, or if possible, on a rack set over a dish.
Heat a non-stick pan over medium-low heat. Melt one tablespoon of butter and spread to coat the pan. Add two slices of the prepared banana bread and brown on each side. Continue with the remaining slices. Serve immediately with fresh fruit and a drizzle of maple syrup.
