Directions
- Preheat Oven: Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
- Mix Wet Ingredients: In a large bowl, combine the peanut butter, honey (or maple syrup), egg, and vanilla extract. Stir until smooth.
- Add Dry Ingredients: Add the protein powder, oats, baking soda, and salt to the wet mixture. Mix until a dough forms. If the dough is too sticky, add a tablespoon of oats or protein powder to help with consistency.

- Shape Cookies: Scoop 1-2 tablespoons of dough for each cookie and roll into balls. Place them on the prepared baking sheet and gently flatten with a fork or your hand.
