Warm, comforting baked oatmeal cups with apple and cinnamon, perfect for easy meal prep and a wholesome breakfast or snack.
Drain grated apple to avoid soggy cups. Use room temperature egg for better mixing. Tent with foil if edges brown too quickly. Adding a tablespoon more oats can help if batter is too wet. For vegan version, replace egg with flax egg and butter with coconut oil.
