Description

You’ll love how quickly these flourless, high-protein peanut butter cookies come together—just peanut butter, vanilla protein powder, and an egg. They’re soft-centered with crisp edges, naturally gluten-free, and perfect for a post-workout treat or a quick coffee break.


Ingredients

Units Scale
  • 1/2 cup natural creamy peanut butter
  • 1/2 cup vanilla protein powder
  • 1 large egg, whisked

Instructions

  1. Preheat & prep: Preheat oven to 350°F (175°C). Line a baking tray with parchment.

  2. Mix the dough: In a medium bowl, combine peanut butter, protein powder, and whisked egg until a thick, uniform dough forms. (If sticky, chill 10 minutes.)

  3. Portion & shape: Scoop ~1 tablespoon portions (about 10 balls). Place on tray.

  4. Criss-cross press: Lightly wet a fork and press each ball to ~1/2-inch thickness, then rotate 90° and press again for the classic pattern.

  5. Bake: Bake 4–5 minutes until edges are set. Centers will look slightly soft; they firm up as they cool. Cool on the tray a few minutes, then transfer to a rack to cool completely.

Notes

  • Texture tips: Brands of peanut butter and protein powder vary. If dough seems dry, add 1–2 teaspoons water or a drizzle of melted coconut oil; if too sticky, chill.
  • Sweetness options: For sweeter cookies, mix in 1–2 tablespoons granulated sweetener (sugar, coconut sugar, or a zero-calorie sweetener).
  • Mix-ins (optional): Fold in mini chocolate chips, chopped peanuts, or a pinch of cinnamon or vanilla extract.
  • Storage: Store airtight at room temperature 3–4 days or freeze up to 2 months.
