Air Fryer Single Serve Protein Brownie Cookie

Author: jazzleaf_ • Dec 23, 2025

This Air Fryer Single Serve Protein Brownie Cookie is your answer to a warm, gooey dessert moment—without the hassle of baking a whole batch. Made with just banana, peanut butter, and FlavCity's Brownie Batter All-In-One Protein Smoothie Powder, it delivers rich, brownie flavor in under 20 minutes. Crispy on the edges, soft in the center, and perfectly sized for one. Top it off with melty chocolate chips and flaky salt for the ultimate finish.

Ingredients

Directions

  1. Mash the banana in a small bowl until it’s smooth.
  2. Add the peanut butter and Flavcity Brownie Batter protein powder. Mix until a thick dough forms. It will be gooey, that's fine!
  3. Chill the dough in the freezer for 5 minutes to help it firm up.
  4. Form into one large cookie on a small square of parchment paper.
  5. Air fry at 350°F for 13 minutes, until the edges look set and the center is just soft.
  6. Remove the cookie from the air fryer, and add the chocolate chips and flakey sea salt on top. Let it melt. 
  7. Let cool for 5 minutes before lifting, it’ll firm up as it cools.

Jazz’s Tips
Don’t skip the chill step! This helps the cookie hold its shape.

Slightly underbake for that gooey brownie center.

Use any flavor Flavcity Protein Powder!
