Heat the base: In a small saucepan, combine oats, milk, and water.
Add a pinch of salt. Bring to a gentle simmer over medium heat, stirring occasionally.
Cook to creamy: Reduce heat to low and cook for 3 to 5 minutes until the oats are soft and thickened. Add a splash more milk if needed.
Whisk the flavor mix: In a small bowl, mix protein powder, cocoa powder, and a few tablespoons of warm milk or water to make a smooth paste.
This helps prevent clumps.
Stir in the paste: Remove oats from heat. Stir in the protein-cocoa paste, vanilla extract, and sweetener until fully combined.
Add the creaminess: Fold in the Greek yogurt. This cools the oats slightly and gives a rich, cookies-and-cream texture.
Top it off: Spoon into a bowl and sprinkle crushed chocolate sandwich cookies on top.
Add cacao nibs or mini chips if you like extra crunch.
Adjust and serve: Taste and adjust sweetness or thickness with more milk. Enjoy warm.
