Thinly slice peaches and add to a 9x9 baking dish.
Sprinkle lemon juice, arrowroot, coconut sugar and cinnamon over peaches, and gently toss to evenly coat.
In a mixing bowl, add almond milk, coconut oil, honey (or date syrup), vanilla, sea salt and baking soda. Stir until mixed well.
Add the almond flour and arrowroot, and then stir until a thick cookie-dough like batter is formed.
Spoon the mixture over the peaches in 3 rows by 3 columns, and then use a spatula to spread the batter to cover the peaches in a rustic but somewhat even covering.
Cover the baking dish is foil. This is important because almond flour browns/burns more quickly than regular flour.
Bake in the Sharp Superheated Steam Countertop Oven on Bake/Reheat at 400º F for 20 minutes. Remove foil, and return to oven for an additional 10 minutes to brown.
If baking in a conventional oven, preheat oven to 400º F. Bake the foil covered dish for 30 minutes, remove the foil, and bake for an additional 15-20 minutes, until the peach mixture is bubbling and the topping is evenly browned.
