This creamy, fiber-rich smoothie captures the crisp sweetness of Red Delicious apples paired with hearty rolled oats for a satisfying breakfast that tastes like apple pie in a glass.
For a thicker 'smoothie bowl' consistency, use frozen apple slices instead of fresh. To make ahead, blend everything except the ice and store in an airtight jar for up to 24 hours; shake well before drinking. You can substitute almond butter with peanut butter or sunflower seed butter for a nut-free version.
