Tips & Variations
- Pro Tip: If your protein powder tends to clump, try mixing it with the milk first to create a smooth liquid before adding it to the rest of the ingredients.
- Chocolate Protein Oats: Use chocolate protein powder and add 1 tablespoon of cocoa powder for a rich, brownie-batter-like flavor.
- Peanut Butter Boost: Stir in 1-2 tablespoons of peanut butter or powdered peanut butter for extra protein and flavor.
- Make it Vegan: Use a plant-based protein powder, a dairy-free yogurt alternative, and non-dairy milk.
Frequently Asked Questions (FAQ)
- What kind of protein powder is best?
- Both whey and plant-based protein powders work well. Choose a flavor you enjoy, as it will be prominent in the final taste. Vanilla, chocolate, or unflavored are all great choices.
- How long do these last in the refrigerator?
- You can meal prep these for up to 4 days. Store them in individual airtight containers in the fridge for an easy grab-and-go breakfast all week.
- Can I use steel-cut or quick oats?
- Rolled oats provide the best chewy texture. Quick oats will result in a much softer, porridge-like consistency, while steel-cut oats will not soften enough without being cooked.

Serving Suggestions
- These high-protein overnight oats are a perfect blank canvas for toppings. Serve them chilled with a handful of fresh berries for antioxidants, a swirl of almond butter for healthy fats, and a sprinkle of chopped nuts for a satisfying crunch.
