In a 8x8 cake pan add the eggs, heavy cream, honey, salt and whisk together well.
Place a skillet on your stove over medium-low heat, add 1 tbsp of the butter and melt.
While butter is melting soak 2 of the banana bread slices in the egg mixture, turn over after 30 seconds and soak on the other side for another 30 seconds.
Once the butter is melted and skillet is hot, add the 2 slices to the skillet and cook for about 3 or 4 minutes. After 3 or 4 minutes take a peek and see if the French toast is golden brown, if it has flip each slice carefully and continue cooking until this side is golden brown, another 3 or so minutes, making sure to watch it closely so it doesn't burn. Remove from skillet.
Soak the remaining 2 slices of bread and repeat the process to cook these last 2 slices.
In the same skillet, prepare the caramelized bananas. Add the 2 tbsp of butter and wait until it melts then sprinkle the tbsp of brown sugar over the surface of the skillet.
Add the banana slices over the brown sugar, and cook for a couple minutes until the bottom of the banana get golden brown. Flip each slice over and cook for another 2 or 3 minutes. Remove from heat.
Dust the banana bread French toast with some icing sugar then spoon the caramelized bananas over the slices and serve.
