These banana fritters are crisp on the outside and tender on the inside, loaded with big chunks of caramelized banana and served with vanilla caramel sauce.
Put the flour, baking powder, baking soda and salt into a bowl and whisk together to combine.
In a separate bowl mash the very ripe banana and whisk together with the egg, lemon juice and vanilla beans. An immersion blender will speed this process up.
Peel and quarter the other banana lengthwise and then cut into cubes. Add the cubed banana in with the dry ingredients and then toss to coat each piece of banana with the flour mixture so they don't clump together.
Heat 2-inches of oil in a heavy bottomed pot to 350 degrees F (180 C). Prepare a wire rack lined with a triple layer of paper towels.
Add the wet ingredients to the dry ingredients and use a spatula to fold the mixture together until just combined. Do not overmix or your fritters will become tough and chewy.
Use a spoon to gently drop spoonfuls of batter into the hot oil and fry on one side until you see the edges starting to turn brown.
Flip and continue frying until brown on the other side. Drain on the prepared rack. Let the fritters cool a bit and then dust with plenty of powdered sugar. Serve warm with vanilla caramel sauce.
