Ingredients
  

  • 1 cup plain Greek yogurt (full-fat = richer, low-fat = lighter)
  • 1/2 cup natural sweetener (honey, maple syrup, or coconut sugar)
  • 1 large egg (room temperature)
  • 1 tsp vanilla extract
  • 1 cup oat flour (or blended oats)
  • 1/2 cup protein powder (vanilla or unflavored whey works best)
  • 1/2 tsp baking soda
  • 1/4 tsp salt
  • 1/2 cup mix-ins (chocolate chips, nuts, dried fruit, or berries)

Instructions
 

  • Preheat & Prep: Set oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone mat.
  • Mix Wet Ingredients: In a large bowl, whisk together Greek yogurt, sweetener, egg, and vanilla until smooth. (And yes, licking the whisk is mandatory
  • Combine Dry Ingredients: In a separate bowl, mix oat flour, protein powder, baking soda, and salt.
  • Bring It Together: Gently fold dry mixture into the wet. Don’t overmix—just until no flour streaks remain. Stir in your chosen mix-ins.
  • Shape the Cookies: Scoop out tablespoon-sized portions, place them on the baking sheet, and flatten slightly.
  • Bake: Bake 10–12 minutes, until edges are golden. Let cool on the sheet for 5 minutes, then transfer to a wire rack.

Notes

  • Sweetness Level: Using honey or maple syrup gives a softer, chewier cookie; coconut sugar creates a slightly crispier edge.
  • Protein Powder Tip: Whey blends best without drying the dough. If using pea or soy protein, add a splash of milk or extra yogurt for moisture.
  • Storage Hack: These cookies actually taste better the next day after the flavors settle—store them airtight overnight before serving if you can resist.
  • Batch Tip: Double the recipe and freeze half. Pull out a cookie or two whenever the craving hits—microwave for 15 seconds, and they taste oven-fresh.
  • Diet-Friendly Swap: To lower carbs, use almond flour instead of oat flour and a sugar substitute like erythritol.
