Preheat oven to 400°.
Combine first 7 ingredients in a large bowl; stir with a whisk. Let stand 15 minutes.
Lightly spoon flours into dry measuring cups; level with a knife. Combine flours and next 3 ingredients in a large bowl; make a well in center of mixture. Add oat mixture to dry ingredients, stirring just until moist. Gently fold in apple.
