Prep the apple: Core and dice 1 medium apple into small cubes. Leave the skin on for fiber and color.
Warm the pan (optional but great): In a small skillet, add a teaspoon of butter or coconut oil. Sauté the apple with a pinch of cinnamon and a tiny pinch of salt for 3–4 minutes until slightly softened and fragrant.
Set aside.
Cook the oats: In a saucepan, combine 1 cup milk and 1 cup water. Bring to a gentle simmer, then stir in 1 cup rolled oats and a pinch of salt. Reduce heat and cook for 5–7 minutes, stirring occasionally.
Add flavor: Stir in 1 teaspoon cinnamon and 1/2 teaspoon vanilla extract (if using).
Fold in the sautéed apples.
Boost the protein: Remove the pot from heat. Whisk in 1 scoop vanilla protein powder until smooth. If using Greek yogurt instead, let the oats cool for 2–3 minutes first, then stir in 1/2–3/4 cup yogurt to prevent curdling.
Healthy fats and fiber: Stir in 1 tablespoon chia seeds or ground flax.
This thickens the oatmeal and adds omega-3s.
Adjust sweetness: Taste and add 1–2 teaspoons maple syrup or honey if needed. The apples may be sweet enough on their own.
Finish and serve: Spoon into bowls. Swirl in a teaspoon of nut butter and top with chopped walnuts or pecans for crunch.
Make it yours: Add a splash more milk for creaminess or an extra sprinkle of cinnamon on top.
