Ingredients for Collagen Protein Blondies

These extra fudgy collagen protein blondies are made without protein powder and only a few healthy ingredients; No eggs, no oil, no sugar and gluten free too.

Unflavored Collagen Peptides needed for high protein brownies. I use the one from Further Foods (HAYLSKITCHEN gives you a discount)
Zero Calorie Brown Sugar – This is the Brown Monkfruuit 1:1 Sugar Substitute from Lakanto, and keeps this recipe sugar free; (code HAYLSKITCHEN for a discount here)
Peanut Butter Powder, also known as Powdered Peanut Butter. I use Lakanto for a sugar free version (the code HAYLSKITCHEN gives you a discount here too)
Coconut Flour
Whole Wheat Pastry Flour – or a regular all purpose flour
Runny Tahini

Non-fat Greek Yogurt contributes to the oil-free part of these high protein brownies since it adds the moisture, and also extra protein
Egg Whites for extra high protein without the added fat from the yolk
Almond Milk or regular milk
Vanilla Extract
Baking Soda

Sugar free White Chocolate Chips or Chopped Chocolate – I use sugar free ones from Lily’s here.

Tips to make Collagen Powder Blondies with no Protein Powder?

This recipe for chocolate chip collagen blondies is extremely easy to make. Here’s some pointers to get it right though.

Mix all the dry ingredients and wet ingredients separately, then combine. You want the mixture to be smooth.

For extra fudgy collagen blondies, let some moisture be there on the tester – this should be at about 25 minutes.
Use a plastic knife to cut the blondies; these collagen protein blondies are quite fudgy and will stick to a metal knife when cutting.

Alternatives for Healthy Protein Blondies without Protein Powder

For the perfect fudgy and moist protein collagen powder blondies bars, I would highly suggest using the ingredients and brands I recommended; I do have some alternatives you can try. I haven’t testing them all, so I can’t say how your recipe might turn out.

Whole Wheat Pastry Flour: All purpose flour or 1:1 Gluten Free Baking Flour, in the same amount by weight.
Zero Calorie Brown Sugar Alternative: Regular coconut sugar or brown sugar (this won’t be sugar free though, and also higher in calories)
Peanut Butter Powder: Regular peanut butter, but reduce milk to 2 Tbsp.
Tahini: Peanut Butter, Almond Butter, Cashew Butter, or any nut or seed butter.
