Combine the flour, sweetener, baking powder,salt and ground cinnamon. Stir in the almond milk just until combined; fold in peaches. Spread the batter into a 8 inch pan either lined with parchment or sprayed with coconut oil.
For the Topping:
Combine water, sweeteners, butter and nutmeg in a small saucepan. Bring to a boil; stirring until sweeteners are dissolved. Whisk in the xanthum gum. Pour over filling. Bake until the filling is bubbly and a toothpick inserted into the topping comes out clean, 40-50 minutes.
