This high-protein shake captures the warm, spiced flavor of Belgian Biscoff cookies in a creamy, guilt-free format. It is the perfect post-workout treat or a quick breakfast that tastes like a decadent dessert.
For a thicker, milkshake-like texture, use a frozen banana instead of ice. To make it dairy-free, ensure your protein powder is plant-based and use a vegan-friendly cookie butter. This shake is best enjoyed immediately but can be stored in an airtight thermos for up to 2 hours.
