Stir the dry ingredients together. Mix the wet ingredients, except for the fruit garnish and oil for greasing. Then stir the wet into the dry.
I recommend letting the mixture soak together, covered and refrigerated, for at least two hours, preferably overnight. Soak time is not included in prep time.
Preheat the oven to 350 F. (at high altitude use 375 F.)
Oil a 9 x 13 baking dish.
Spread the mixture evenly in the oiled pan.
Garnish with the sliced fruit. For the clafoutis pictured here, I sliced the peaches about ¼ inch thick and used just over 2½ peaches (3 inch diameter). I could have sliced them a little thicker and used all 3 peaches. I added the blueberries because I had them on hand and it was a way to cover more of the oatmeal.
Bake for 35 minutes (40 minutes at high altitude).
Remove from the oven and allow to cool for at least 10 minutes before slicing.
Garnish with a dollop of coconut yogurt and enjoy with more fresh fruit!
