Oatmeal Cookies Recipe

4.6 from 125 reviews

These no-bake oatmeal cookies are a simple, wholesome treat made with just three main ingredients: rolled oats, peanut butter, and maple syrup. Perfect for a quick, healthy snack, these cookies require no baking and are naturally gluten-free and vegan-friendly. They offer a chewy, satisfying texture with the rich flavor of nut butter and a touch of natural sweetness.

Ingredients

Scale

Dry Ingredients

  • 1/2 cup + 2 tablespoons (approx. 55g) rolled oats (certified gluten-free if needed)

Wet Ingredients

  • 1/2 cup (125g) unsweetened peanut butter (or almond butter, cashew butter, sunflower seed butter)
  • 2 1/2 tablespoons pure maple syrup (or honey if not strictly vegan)

Instructions

  1. Prepare Baking Sheet: Line a cookie sheet with parchment paper or wax paper to prevent sticking and make cleanup easy.
  2. Make Oat Flour: Add the rolled oats to a food processor or high-speed blender and pulse until the oats are ground into a coarse, flour-like consistency.
  3. Combine Ingredients: In a large mixing bowl, combine the processed oat flour, peanut butter (or your chosen alternative), and maple syrup (or honey).
  4. Mix Dough: Use a sturdy spatula or spoon to thoroughly mix the ingredients until a thick, cohesive dough forms that holds together when pressed.
  5. Check Consistency: If the dough is too dry and crumbly, add small increments of maple syrup or peanut butter (1/2 teaspoon at a time) and mix again. If too wet, add more processed oat flour (1 teaspoon at a time).
  6. Scoop and Shape Cookies: Using a small cookie scoop or spoon (about 1 to 1.5 tablespoons), scoop out portions of dough. Roll each portion into a smooth ball with your hands and place onto the prepared cookie sheet.
  7. Flatten Cookies: Press gently on each dough ball with your palm or the bottom of a measuring cup to form discs about 1/3 inch thick. These cookies will not spread while chilling.
  8. Chill: Place the cookie sheet in the refrigerator for at least 30 minutes to allow the cookies to firm up and set.
  9. Serve: Enjoy the cookies chilled or at room temperature as a healthy, delicious snack.

Notes

  • For a nut-free version, try sunflower seed butter instead of peanut butter.
  • Ensure oats are certified gluten-free if you require gluten-free baking.
  • Adjust sweetness by varying the amount of maple syrup or honey.
  • Store cookies in an airtight container in the refrigerator for up to one week.
  • These cookies do not bake or spread, so shaping is important for consistent texture.
