A protein brownie for one made in the air fryer in under 10 minutes. Probably the most quick fix dessert. Okay I guess microwave recipes are faster, but come on, can you say no to a brownie like this?

Just mix everything up and air fry it. I was actually surprised how little time this took coz it literally was just 6 minutes in there.

I was considering revamping the recipe to make it even more protein-packed, but it was so good with even 24 grams of protein husband asked me not to touch it!

Ingredients for Air Fryer Protein Brownie Recipe

This single serving air-fryer protein brownie is made with a few simple and healthy ingredients, and has no butter or oil and no sugar sugar either! 

• Chocolate Protein Powder for high protein brownie that's also sugar free.
  I used Quest Chocolate Milkshake flavor since its whey-casein and bakes well.
• Unsweetened Cocoa Powder or Cacao Powder
• Coconut Flour
• An Egg White
• Unsweetened Almond Milk
• A bit of Vanilla Extract
• Baking Powder

And then of course.. Chopped Chocolate or Chocolate Chips! I'd recommend the sugar free ones from Lakanto. Use my code HAYLSKITCHEN for a 15% discount on all the Lakanto products on their website!

How to Make a Protein Powder Brownie for One in the Air-Fryer

No preheating, no waiting on an oven.

• Whisk the dry ingredients: In a small bowl, whisk the chocolate protein powder, cocoa powder, coconut flour and baking powder until there are no streaks of cocoa left. Coconut flour and cocoa powder can clump, so break those up now - they won't dissolve once the liquid goes in.

• Add the wet ingredients: Pour in the almond milk, egg white and vanilla, then mix until the batter is smooth and thick, closer to frosting than to cake batter.
• Fold in the chocolate: Gently fold in the chopped chocolate or chocolate chips. Stop as soon as they're distributed. Overmixing at this stage is what turns a protein brownie tough and gummy.

• Fill the ramekin: Grease a ramekin well with cooking spray, scrape the batter in, and smooth the top with the back of a spoon. Scatter a few extra chocolate chips over the top so they melt into the surface.
• Air fry: Cook at 325°F for 6 minutes. If your air fryer jumps from 320 to 330 with nothing in between - a lot of them do - go with 330 for 6 minutes. One reader tried 320 for 6 and had to put it back in, so the higher setting is the safer choice.
• Pull it early: Take the brownie out while a tester still comes out moist. It keeps cooking in the hot ramekin, and that carryover is what gives you the fudgy center instead of a dry one.

Prefer the oven? Bake at 350°F for about 12 minutes.

Tips to make Air Fryer Protein Fudge Brownie

This air-fryer protein fudge brownie really is an easy one, but make sure you do all of this stuff to get is perfect.

• Grease the ramekin!

• Use room temperature egg whites and milk;
  This is so the wet ingredients and dry ingredients can mix well.

• 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,  protein powder will make your protein brownie 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.

• Take the brownie out when tester is still moist - it will continue to cook when out, and  you want the proper fudge brownie center.
