Meanwhile, wipe out the same skillet, put over medium heat, and melt remaining butter. Add the peaches and cook for 2–3 minutes until they begin to soften. Stir in the maple syrup, brown sugar, vanilla, cinnamon, and salt.
Note: If peach mixture is thickening too quickly, add in 1 tsp of water at a time to help thin it out.
Continue cooking for another 4–6 minutes, stirring occasionally, until the peaches are tender and the syrup has thickened into a glossy glaze. Remove from the heat and stir in the lemon juice.
To serve, arrange the French toast on a platter or individual plates and generously spoon the warm peach maple topping over each slice. Finish with a dusting of powdered sugar, toasted pecans if you wanted, and an even a dollop of whipped cream, if you really want to go crazy.
