Ingredients

Wet Ingredients

  • 1 cup creamy peanut butter (not drippy)
  • 2/3 cup coconut sugar (or packed brown sugar)
  • 2 large eggs (room temperature)
  • 1 1/2 teaspoons vanilla extract

Dry Ingredients

  • 1/2 teaspoon baking soda
  • 1/2 teaspoon kosher salt
  • 2/3 cup vanilla protein powder (whey or plant-based works)

Add-ins

  • 1/2 cup chocolate chips or chunks (dairy-free or regular, plus more for topping)

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (177°C). Line a large baking sheet with parchment paper to prevent sticking and make cleanup easier.
  2. Whisk Wet Ingredients: In a large bowl, whisk together the peanut butter, coconut sugar (or brown sugar), eggs, and vanilla extract until the mixture is smooth and creamy, about 2 minutes.
  3. Add Dry Ingredients: Using a rubber spatula, gently stir in the protein powder, baking soda, and salt until just combined. Then fold in the chocolate chips, ensuring an even distribution without overmixing.
  4. Scoop and Shape Dough: Use a medium cookie scoop (approximately 2 tablespoons) to portion the dough. Roll each scoop into a ball and place it on the prepared baking sheet, spacing them about 2 inches apart to allow room for spreading.
  5. Bake the Cookies: Bake in the preheated oven for 8–10 minutes, or until the edges turn lightly golden and the tops are just set. Avoid overbaking to keep the cookies soft and chewy.
  6. Cool and Finish: Let the cookies cool on the baking sheet for 5 minutes to firm up slightly, then transfer them to a wire rack to cool completely. While the cookies are still warm, press extra chocolate chips onto the tops and optionally sprinkle with flaky salt for enhanced flavor.

Notes

  • For best texture, use room temperature eggs to help blend the dough smoothly.
  • You can substitute coconut sugar with packed brown sugar if preferred.
  • Choose your favorite vanilla protein powder, whether whey or plant-based, to suit dietary needs.
  • Do not overbake the cookies; they will continue to firm up as they cool.
  • Adding flaky salt on top enhances the sweet and salty flavor combination.
  • Store baked cookies in an airtight container at room temperature for up to 5 days.
