For more calories: Add 30–40 g rolled oats and another spoonful of peanut butter.
Dairy-Free: Replace the Greek yogurt with 100–150 g unsweetened coconut or almond yogurt, swap the milk for your favourite plant-based milk, and use a dairy-free plant protein powder. The result remains creamy, filling and high in protein without the dairy.
For a lighter shake: Use semi-skimmed milk and 10 g peanut butter.
For extra nutrition: Add a teaspoon of chia seeds.
For a berry version: Replace the banana with 100 g frozen berries and use vanilla whey instead of chocolate.
