Why This Recipe Works
- Incredibly quick and easy: With just 5 minutes of prep the night before, you’ll wake up to a ready-to-eat snack or breakfast
- Healthy, high protein and nutritious: This recipe is made with wholesome and nutritious ingredients including oats, chia seeds, Greek yogurt and peanut butter, keeping you feeling full and satisfied too. Oats are a great source of fiber, antioxidants and other vitamins and minerals, as well as being very filling too. Plus, chia seeds are rich in protein, antioxidants and other nutrients including omega-3 fatty acids and fiber. Plus, the addition of peanut butter (great source of protein), adds to the nutrient profile. Greek yogurt is also protein-rich and vitamin B12 as well as other vitamins and minerals.
- No refined sugar: this recipe is a healthier twist on classic overnight oats recipes - as it contains no added refined sugar - no white or brown sugar!
- Practical and budget-friendly: this recipe is super simple, requires no baking and is made with simple, budget-friendly and wholesome ingredients.
Ingredients You'll Need
- Rolled oats: Old-fashioned rolled oats work best for a creamy texture.
- Chia seeds: These add extra fiber, omega-3s, and a pudding-like texture. Just like our pineapple chia seed pudding, chia seeds are included to bring a wonderful creaminess.
- Peanut butter: use crunchy or smooth peanut butter, look for brands which are unsalted and contain no added sugar or palm oil.
- Milk: You can use dairy or non-dairy milk depending on your preference.
- Greek yogurt: for added protein and creaminess. Look for brands with no added sugar or preservatives.
- Maple syrup: for sweetness. Use Grade A refined sugar-free maple syrup.
- Vanilla extract: for a warm flavor. Look for vanilla extract with no added sugar.
- Chocolate chips: use semi-sweet or dark chocolate chips for a lovely contrast in flavor. You can use regular or mini chocolate chips. Look for refined sugar-free or sugar-free chocolate chips.

- Nut or seed butters: substitute with cashew butter, sunflower seed butter or almond butter if desired. This will alter the taste of these overnight oats.
- Add-ins: you can also add in a teaspoon of vanilla protein powder (or chocolate protein powder) if preferred.
