Warm the base: In a small saucepan, combine oats, milk, water, and a pinch of salt. Bring to a gentle simmer over medium heat, stirring occasionally.
Cook the oats: Reduce heat to medium-low and cook for 3–5 minutes until the oats thicken and are soft but not mushy.
Stir to prevent sticking.
Add peanut butter: Stir in the peanut butter until fully melted and the oats look glossy and creamy.
Mix in protein: Remove the pan from heat. Sprinkle in the protein powder gradually, whisking or stirring well to avoid clumps. Add a splash of milk if it gets too thick.
Create the cheesecake vibe: Stir in Greek yogurt and vanilla.
Taste and sweeten with maple syrup or honey as needed.
Finish and serve: Spoon into a bowl and top with your favorite add-ons. Enjoy warm.
