Prep your apple. Wash, core, and dice one medium apple into small pieces.
Leave the skin on for extra fiber and color.
Heat the base. In a medium pot, add 1 cup milk and 1 cup water. Bring to a gentle simmer over medium heat.
Add oats and flavor. Stir in 1 cup rolled oats, a pinch of salt, 1/2 to 1 teaspoon cinnamon (to taste), and a splash of vanilla. Reduce heat to low and cook, stirring occasionally, for 5β7 minutes.
Soften the apples. Stir in half of the diced apple so it can soften slightly and infuse the oats.
Save the rest for topping.
Boost nutrition. If using, add 1 tablespoon chia seeds or ground flaxseed during the last minute of cooking. This thickens the oats and adds fiber.
Sweeten lightly. Taste and add 1β2 teaspoons maple syrup or honey if you want a touch more sweetness.
Finish with creaminess. Remove from heat. For extra protein, swirl in 2β3 tablespoons Greek yogurt or a spoonful of almond or peanut butter until smooth.
Assemble the bowl. Spoon oats into a bowl and top with the remaining apple, a sprinkle of nuts, and a few raisins or dried cranberries if you like.
Add an extra dash of cinnamon on top.
Serve warm. Enjoy immediately while itβs creamy and fragrant.
