Full recipe details are in the printable recipe card below.

This recipe was formulated for whey protein concentrate, and I do not recommend substituting other types of protein powder. Different types of protein powders bake very differently! Read more here: The Best Protein Powders for Baking.

Inulin is a plant-based prebiotic fiber, and it is a key ingredient for blondie/bar texture.

Mashed bananas can be subbed for the applesauce. In this case, you may need to lessen the bake time slightly to account for the change in texture.

How to make Chocolate Chip Protein Blondies

Step 1: Preheat oven to 325F (165C) and line an 8" square pan with parchment paper.

Step 2: Mix applesauce and coconut oil with a whisk until well combined.

Step 3: Add remaining ingredients, except for chocolate chips, and mix well. It may look grainy at first, but it will become more smooth as the whey protein hydrates.

Step 6: Bake for 18-20 minutes, or until the edges are firm. The center can be a little less firm, as it will set as the blondies cool. Let the blondies cool to room temperature on a wire cooling rack.

Recipe Variations

Peanut Butter Swirl: Swirl 2 tablespoons of peanut butter into the top of the batter before baking for a rich, nutty twist.

Go Nuts!: Add 2 tablespoons of chopped nuts to the batter before baking. I recommend pecans!

High-Fiber Boost: Mix in 1 tablespoon of ground flaxseed or chia seeds for added fiber and healthy fats.

FAQ

Can I sub a different type of protein powder for the whey?

Can I sub a different flour for the coconut flour?

I wouldn't recommend almond flour, but fine gluten free flours (without added gums) should be ok. Flours with gluten will likely make the texture tough and bready.

What can I sub for the inulin?

Inulin is a key ingredient here, so I don't recommend substituting or omitting it. Without inulin, the recipe would be more cake-like. Inulin gives it the chewy bar/blondie texture.
