Ingredients
- 45 g (approx. 1.5 scoops) Whey protein powder (vanilla or chocolate)
- 40 g (1/2 cup) Rolled oats (old-fashioned)
- 350 ml (1.5 cups) Unsweetened almond milk
- 32 g (2 tbsp) Natural peanut butter
- 118 g (1 whole) Medium banana
Instructions
- Place the rolled oats into a high-speed blender and pulse for 10-15 seconds until they reach a fine, flour-like consistency to ensure a smooth texture.
- Peel the banana and break it into 3-4 chunks, adding them to the blender.
- Add the whey protein powder, natural peanut butter, and almond milk to the blender canister.
- Secure the lid tightly and start the blender on the lowest speed, slowly increasing to high.
- Blend for 45-60 seconds, or until the oats are fully pulverized and the mixture is completely smooth.
- Check the consistency; if the shake is too thick, add an additional 30-50ml of water or almond milk and pulse briefly to combine.
- Pour into a large glass or shaker bottle and serve immediately for the best texture.
Pro tips
- To achieve a smoother texture, soak the oats in the almond milk for 15 minutes before blending.
- For a higher protein boost, swap 10g of the oats for an additional half-scoop of protein powder.
- Budget swap: Use cow's milk instead of almond milk for a cheaper protein source and creamier mouthfeel.
- Avoid using instant oats if possible, as they can sometimes create a gummy texture; rolled oats provide a better nutritional profile and consistency.
- If you are meal prepping, blend the dry ingredients (oats and protein) ahead of time in a shaker cup, then add the wet ingredients just before serving.
Storage & reheating
This shake is best consumed immediately. If stored, keep in an airtight container in the refrigerator for up to 24 hours. The oats will absorb liquid over time, so you may need to add a splash of water and shake vigorously before drinking.

Frequently asked questions
Can I use quick oats instead of rolled oats?
Yes, quick oats will blend even faster, though the texture may be slightly thinner.
Is this suitable for a vegan diet?
You can make this vegan by substituting the whey protein with a high-quality pea or soy protein isolate.
Can I prep this the night before?
Yes, but note that the oats will thicken the shake significantly; store in the fridge and add a little extra liquid in the morning.
What if I don't have a high-speed blender?
Use oat flour instead of whole rolled oats to ensure a smooth consistency without needing a professional-grade blender.
