How to Make a Protein Wendy’s Frosty

1. Add your milk of choice to the blender cup.
2. Add all dry ingredients on top of the milk.
3. Fill the cup with ice all the way to the fill line.
4. Blend until thick and fully combined.

Pro tip: Do not overblend. Blending too long will thin the mixture and make it less Frosty like.

Frequently Asked Questions

Can I use any blender for this recipe?

Yes. We use our nutribullet, but any blender will work as long as it can safely handle ice. High speed blenders, personal blenders, or standard countertop blenders are all great options.

What makes this Frosty thick and creamy?

The xanthan gum is key. It gives this protein Frosty that classic Wendy’s texture, thick, creamy, and spoon worthy.

Can I use a different protein powder?

Absolutely. Any chocolate protein powder will work, though flavor and sweetness may vary depending on the brand.

Is this recipe good for breakfast?

Yes. Thanks to the protein content, this Frosty works great as a quick breakfast (any meal, really!), especially on busy mornings when you want something filling but refreshing.

Can I make this without Splenda?

You can swap Splenda for another sweetener if preferred. Adjust to taste since sweetness levels can vary.

What if I do not have the Skinny Hot Chocolate Mix?

You can still make the recipe, but we highly recommend using it. It is the true hero that gives this Frosty its rich, chocolatey flavor. The recipe is featured on the blog here. You can also utilize any hot chocolate mix that you might have on hand (Swiss Miss, Nestlé, Ghirardelli), it will just have a higher calorie count.
