This high-protein shake captures the nostalgic flavors of the classic Abba Zabba candy bar, blending creamy peanut butter with a sweet marshmallow-vanilla base for a healthy post-workout treat.
To make this lower in sugar, replace the marshmallow fluff with a sugar-free marshmallow flavored syrup. For a thicker, milkshake-like consistency, use a frozen banana instead of half the ice. Store any leftovers in a sealed jar in the fridge for up to 24 hours, though separation may occur.
