Ingredients

1 cup old fashioned rolled oats
2 scoops (50 grams) protein powder (vanilla or chocolate)
2 cups unsweetened vanilla almond milk
2 tablespoons cocoa powder
1 tablespoon maple syrup
1 teaspoon vanilla extract
Pinch of sea salt
2 tablespoons chocolate chips
2 tablespoons chopped walnuts
1 tablespoon peanut butter (optional)

Instructions

Step 1: In a bowl or jar, combine the oats, protein powder, almond milk, cocoa powder, maple syrup, vanilla extract, and sea salt. Stir well until the protein powder is fully dissolved and everything is evenly mixed.
Step 2: Seal the container with a lid and place it in the refrigerator overnight to allow the oats to soak and soften.
Step 3: The next morning, take the container out and stir the mixture. If it looks too thick, add a splash of almond milk to reach your preferred consistency.
Step 4: Divide the oatmeal into two portions. Top each with chocolate chips, chopped walnuts, and peanut butter if using, then enjoy immediately.

Tips & Variations

For a nut-free version, omit the walnuts and peanut butter or substitute with seeds like sunflower or pumpkin seeds.
Use a flavored protein powder like chocolate for an extra indulgent brownie taste.
If you prefer a sweeter oats, increase the maple syrup slightly or add a drizzle of honey just before serving.

Storage

Store any leftover overnight oats in a sealed container in the refrigerator for up to 3 days. Stir well before eating and add a little almond milk if the mixture thickens too much. It can be enjoyed cold or warmed briefly in the microwave.

FAQs

Can I use other types of milk instead of almond milk?

Yes, you can substitute almond milk with any milk of your choice, such as cow’s milk, oat milk, or soy milk, depending on your taste and dietary preferences.

Is it necessary to use protein powder in this recipe?

Protein powder adds extra protein and helps give the oats a creamy texture, but you can leave it out or replace it with Greek yogurt if preferred. The oats will still taste great without it.

Base Ingredients

1 cup old fashioned rolled oats
2 scoops (50 grams) protein powder (vanilla or chocolate)
2 cups unsweetened vanilla almond milk
2 tablespoons cocoa powder
1 tablespoon maple syrup
1 teaspoon vanilla extract
Pinch of sea salt

Toppings

Instructions

Combine Ingredients: Add the rolled oats, protein powder, almond milk, cocoa powder, maple syrup, vanilla extract, and sea salt into a bowl or jar. Stir thoroughly to blend all ingredients and dissolve the protein powder completely.

Store leftovers covered in the refrigerator for up to 2 days.
To make it vegan, ensure the protein powder used is plant-based and check the toppings accordingly.
