Preheat oven to 375 degrees F.
Halve the peaches and remove pit. Place them in a baking dish, skin side down. Place a-teaspoon ground almond and a-teaspoon sugar in the hollow of each peach.
Then place 1/2 teaspoon butter on top and sprinkle with cinnamon.
Bake until topping is golden brown and peaches are tender, about 30 minutes. Serve the baked peaches warm with a scoop of vanilla ice cream.
