5-Minute Strawberry Protein Fluff (Whey, Frozen Berries)

One cup of frozen strawberries, one scoop of protein powder and a splash of milk go into the bowl. A few minutes of whipping later, the bowl is full: pale pink, light as mousse and about three times the size you started with. That is protein fluff, and a whole bowl of it comes in at around 210 calories.

It is closer to a soft-serve or a fruit whip than a smoothie. You eat it with a spoon, straight away, while it is cold and airy.

What You Need

• 1 cup (about 140 g) frozen strawberries – they must be frozen. The cold is what lets the mixture hold its shape.
• 1 scoop (about 30 g) vanilla whey protein powder – whey, or a blend based on whey, is what whips up. More on that below.
• ⅓ cup milk – just enough liquid to get the mixture moving.
• ¼ teaspoon xanthan gum (optional) – makes the fluff thicker and slower to deflate. Do not go over ½ teaspoon.

How to Make It

1. Add everything at once

Put the frozen strawberries, protein powder, milk and xanthan gum into a food processor or a large mixing bowl. Use a bigger bowl than you think you need: it triples.

2. Whip on high

In a food processor, run it on high for 2 to 3 minutes. With an electric hand mixer, whip on high for 5 to 8 minutes.

3. Stop when it has tripled

It is ready when it is pale pink, fluffy and holds soft peaks, and has roughly tripled in volume. Eat it right away.

Why Whey Protein Matters

Whey is the protein from the liquid left over when milk is separated into curds and whey, the same split that happens in cheesemaking, as the University of Maine Cooperative Extension describes for cottage cheese. Whey protein foams when whipped, which is why recipes for protein fluff call for it. Plant-based powders are not recommended here, as they do not whip the same way.

The same goes for timing. Protein fluff starts to deflate as it sits and does not freeze well, so make it when you are ready to eat it.

Frequently Asked Questions

What can I top it with?

Sliced fresh strawberries, a few chocolate chips or a crumbled graham cracker. For a creamier high-protein dessert with no whipping at all, try this cottage cheese protein cake batter.

Is it a snack or a dessert?

Either. It is a light dessert after dinner or a post-workout snack. If you like grab-and-go snacks, these pumpkin spice protein balls keep in the fridge, and these crispy cottage cheese chips cover the savoury side.

I want a real strawberry dessert. Any ideas?

When strawberries are in season, this fresh strawberry pie is the classic.

Ingredients Method Notes

Ingredients

  

• 1 cup frozen strawberries about 140 g, still frozen
• 1 scoop vanilla whey protein powder about 30 g
• 1/3 cup milk
• 1/4 teaspoon xanthan gum optional, no more than 1/2 teaspoon

Method

 

1. Put the frozen strawberries, protein powder, milk and xanthan gum (if using) in a food processor or a large mixing bowl.
2. In a food processor, run on high for 2 to 3 minutes. With an electric hand mixer on high, whip for 5 to 8 minutes instead.
3. Stop when the mixture is pale, fluffy and about three times its starting volume. Eat right away.

Notes

Protein powder: use whey or a whey blend; it is what whips into a stable foam.

Xanthan gum is optional; it makes the fluff thicker and slower to deflate. Do not use more than 1/2 teaspoon.

Serve immediately: protein fluff deflates as it sits and does not freeze well.
