Why This Recipe Works (Quick Science)
The oats and chia seeds soak up the liquid overnight, which makes everything thick and creamy. Greek yogurt and protein powder add protein that helps keep you full longer. Peanut butter adds healthy fat, which also helps with fullness and gives the oats that rich cookie dough flavor. The mini chocolate chips bring sweetness and texture without needing lots of sugar.
Tools You’ll Need

Pro Tips

- If the oats get too thick overnight, stir in a splash of almond milk before eating.
- For an even stronger cookie dough flavor, use a tiny pinch of cinnamon.
Substitutions and Variations

- Use chocolate protein powder for a richer chocolate flavor.
- Replace maple syrup with honey.
