Preheat the oven to 375 degrees F
Take a 9-10.5" baking pan or cast iron skillet and grease with a little bit of coconut oil
Layer the bottom of the pan with slices of one peach and 6 ounces of blueberries (reserving the remainder peach slices and blueberries to top)
Mix together the rolled oats, baking powder, cinnamon powder, salt, and almonds in a large mixing bowl
Spread the dry mixture evenly over the top of the bottom fruit layer in the pan
Top the oat layer with the remaining peach slices and blueberries
Mix together the large egg, almond milk, vanilla extract, honey/maple syrup, and coconut oil in mixing bowl until the egg and the coconut oil are thoroughly mixed throughout
Pour the liquid ingredients over the fruit and dry ingredients in the pan
The pan will be be very full with liquid but not to worry, the oats will absorb it all while cooking
Place in the preheated oven for 30-40 minutes until the oatmeal has set throughout
Once it is finished cooking, allow to sit for a few minutes to cool
Serve with vanilla yogurt or extra maple syrup on top and enjoy!
