Why you'll love this recipe
Make-ahead. Overnight oats are the perfect breakfast meal prep option.
Oatmeal. If you love oatmeal but don't have time to cook it every morning, overnight oats like frozen mixed berry overnight oats and banoffee overnight oats are your new best friend.
Dessert for Breakfast. This recipe combines peanut butter, chocolate, and banana to create a breakfast that feels indulgent like brownie baked oats or almond croissant baked oats.
High Protein. With Greek yogurt, protein powder, and chia seeds, this recipe provides a boost of protein to keep you full longer.
Ingredients and substitutions

Rolled oats. Rolled oats are preferred over steel-cut oats because of how they absorb the liquid. If you use a different type of oats, you may have to adjust the liquid. You could also blend the oats for a more mousse feeling like in my blended Oreo overnight oats.
Chia seeds and yogurt. These help thicken the overnight oats and are often forgotten on recipes where people say they don't like the texture. I highly recommend including both, but you can adjust the yogurt to milk ratio.
Greek yogurt. Greek yogurt adds creaminess and a boost of protein, substitute for dairy-free if preferred.
Milk. You can use dairy or non-dairy alternatives depending on your preferences.
Protein powder. Protein powder is optional. Simply omit if preferred.
Banana. Banana is mashed into the mixture to add some natural sweetness. I recommend a dark coloured banana (as these will be slightly sweeter).
Cacao powder. Cacao powder provides the rich chocolate flavor. If you use a chocolate protein powder, you could omit the cacao powder.
Peanut butter. Look for a peanut butter that has only 2 ingredients (peanuts and salt) as this will add the best peanut taste.

Meal prepping overnight oats
To meal prep these overnight oats, you'll need a mason jar or airtight container to store the oats in the fridge. However, you could store in a large container and just spoon out what you need each day into a bowl. Store either way in the fridge for up to 4-5 days.
You can reheat overnight oats if you want a warm breakfast by adding a little extra liquid and microwaving on 1 minute intervals until heated through (approx. 2-3 minutes depending on how thick they are).
