These cookie dough overnight oats taste like dessert but are made with wholesome ingredients and protein powder. It's an easy, high-protein breakfast you can prep ahead for busy mornings.
In a mason jar or airtight container, stir together oats, protein powder, chia seeds, cinnamon and salt. Add almond milk, cashew butter, maple syrup and vanilla. Stir until everything is well combined.
Stir in mini chocolate chips.
Cover and refrigerate overnight (or at least 4 hours).
In the morning, give it a good stir. Add an extra splash of milk if needed and top with more chocolate chips or a drizzle of nut butter before serving.
Notes
Protein powder: Both whey and plant-based protein powder work well. Plant-based protein absorbs more liquid, so you may need closer to 1 cup of milk.
Meal prep: This recipe is great for meal prep. Double or triple the batch and portion into individual jars for easy grab-and-go breakfasts.
Storage: Store overnight oats in an airtight container in the refrigerator for up to 4–5 days. Stir before serving and add a splash of milk if needed.
