Tips for Perfect Protein Powder Brookies

These protein powder brookies are dense and just spot on, but actually very easy to make!

Use room temperature milk and yogurt;
This is so the wet ingredients and dry ingredients of the brownie and cookie layers can mix well.

Use Runny Tahini and Runny Peanut Butter also so that it mixes well into the batter

Don’t over-mix the batter!
Make sure you gently fold the dry mix into the wet to combine them.
If you over-mix it, the protein powder will make the fudgy brownies and cookie tough, dense and gummy.

Taste the batter and see if you need some extra sweetener. I’d recommend using stevia powder to maintain the consistency of the batter and have sugar free and healthy brookies.

Don’t over-bake the brookies or they might get tough; Remove when the tester/knife comes out still moist.
Under-baking a little is okay.

This high protein cookie brownie bars recipe keeps well for a meal prep dessert or post workout snack and is freezer friendly too!

Store protein powder brookie bars at room temperature in an airtight container for 1-2 days or in the fridge for a week.

To freeze healthy cookie brownie bars, individually wrap in plastic wrap and place in freezer-safe zipper bags or air tight container; They should keep for 2-3 months.

Alternatives for Healthy Brookie Recipe

For the perfect low calorie healthy brookie recipe, I used protein powder and monkfruit sweetener – no sugar – and I would highly suggest using the ingredients recommended.

I do have some alternatives you can try. I haven’t testing them all, so I can’t say how the recipe might turn out.

For the brownie:

1:1 Gluten Free Baking Flour: All purpose flour or Whole Wheat Pastry Flour, in the same amount by weight not cups.
Greek Yogurt: Coconut Yogurt
Almond Milk: Any other milk
Golden Monkfruit Sweetener: Regular confectioners sugar or coconut sugar (this won’t be sugar free though, and also higher in calories)
Tahini: Almond Butter, Cashew Butter or any nut or seed butter. Peanut butter might add too strong a taste so I wouldn’t recommend it.

For the cookie:

1:1 Gluten Free Baking Flour: All purpose flour or Whole Wheat Pastry Flour, in the same amount by weight not cups.
Greek Yogurt: Coconut Yogurt
Almond Milk: Any other milk
Brown Monkfruit Sweeter: Regular Brown sugar (also not sugar free or low calorie anymore)
Peanut Butter Powder: 2 Tbsp Peanut Butter, but also use only 2 Tbsp Milk
Peanut Butter: Almond Butter, Cashew Butter or other nut/seed butter

For Vegan Brookies:

This healthy brookies recipe has no milk or eggs or butter, so can easily be made Vegan with the right substitutes.

For a Vegan brookie recipe, use appropriate protein powder and replace Greek Yogurt with coconut yogurt.
