Make these easy, high-protein breakfast cookies using oats and peanut butter for a quick, wholesome grab-and-go morning meal. They are perfect for meal prepping.

Ingredients

Scale
  • 2 cups rolled oats
  • 1 cup whole wheat flour or oat flour
  • 1 teaspoon baking soda
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon salt
  • 1 cup natural peanut butter
  • 1/2 cup maple syrup or honey
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1/2 cup milk (dairy or non-dairy)
  • 1/2 cup mix-ins (e.g., mini chocolate chips, dried fruit, or chopped nuts)

Instructions

  1. Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper.
  2. In a large bowl, whisk together the rolled oats, flour, baking soda, cinnamon, and salt.
  3. In a separate bowl, mix the peanut butter, maple syrup, egg, and vanilla extract until smooth.
  4. Add the wet ingredients to the dry ingredients. Mix until just combined.
  5. Stir in your chosen mix-ins. The dough will be thick.
  6. Drop rounded tablespoons of dough onto the prepared baking sheets, leaving about 2 inches between each cookie. Gently press down on the tops to flatten slightly.
  7. Bake for 12 to 15 minutes, or until the edges are lightly golden brown.
  8. Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.

Notes

  • For a high-protein version, add 1/2 cup of vanilla or unflavored protein powder with the dry ingredients. You may need to add an extra splash of milk.
  • These cookies freeze well. Place cooled cookies in an airtight, freezer-safe container for up to 3 months. Thaw overnight or microwave briefly before eating.
  • Substitute peanut butter with almond butter or sunflower seed butter for different flavors.
