In a bowl combine the oat flour, oats, brown sugar, pumpkin pie spice, baking soda and salt.
Whisk together and add melted butter. Use a fork to combine it into clumps.
Wash and peel your apples. Cut into slices and add to a sauté pan along with the maple syrup, melted butter, pumpkin puree, cornstarch, pumpkin spice and vanilla extract.
Sauté for 4-5 minutes until the apples are tender and the mixture has thickened.
