I am continuing to make healthier versions of my favorite sweets this week. Usually, the oatmeal cookies I make are soft and chewy. What I like about these is that they are firmer with a crispy, crunchy texture.

Ingredients

  • Peanut Butter
  • Maple Syrup
  • Quick Oats

Peanut Butter: Make sure to use natural unsweetened peanut butter to make these cookies. This is the kind of peanut butter that doesn’t contain any added oils. It’s just peanuts and salt in the ingredient list. Your dough will not thicken if you use regular peanut butter.

Maple Syrup: I used pure maple syrup to make these cookies. The syrup provides sweetness but also thickens the dough.

Quick Oats: The quick oats help bind the cookie dough and also adds to the texture of these cookies

Cookie Texture

These cookies have a slightly crunchy texture without being hard. They are also lightly sweetened. They remind me of a biscuit cookie.

How to Make Peanut Butter Oatmeal Cookies

  • Add the peanut butter, maple syrup, and the oats. Stir until everything is combined and oats are fully coated and your mixture becomes a thick cookie dough.
  • Divide dough into 1 tbsp portions. Roll each into a ball and then flatten into a round disk on your prepared cookie sheet.
  • Bake cookies for about 10 minutes. Let them cool and then they are ready to eat!

3 Ingredient Healthy Peanut Butter Oatmeal Cookies

These peanut butter oatmeal cookies are crunchy and lightly sweet. They are very easy to make and just 3 ingredients.

Ingredients

  • 1/2 cup (128 g) unsweetened natural peanut butter
  • 1/4 cup (59 ml) pure maple syrup
  • 1/2 cup + 2 tbsp (50 g) quick oats

Instructions
 

  • Preheat oven to 350°F (177°C). Line a large cookie sheet with parchment paper or silicone baking mat.
  • Add peanut butter, syrup and oats into a large mixing bowl. Stir until maple syrup is completely incorporated into the peanut butter and oats are fully coated. Your mixture should resemble a thick cookie dough.
  • Portion the dough into 1 tbsp pieces (I packed the dough into my tablespoon). Take one piece of dough and roll between palms until it forms a round ball. Place it onto your prepared cookie sheet and then flatten the dough ball until it becomes a round disk (about 1/4 inch thick). You can do this with the back of a metal spoon or the palm of your hand. Space cookies about 1/2 inch apart. The cookies don't spread during baking so you don't need to space them out as much.
  • Bake cookies for about 9-10 minutes (I baked mine 10 minutes) or until the surfaces look cooked. Let cookies cool completely on the cookie sheet before removing.

Notes

  • Make sure to use natural peanut butter. This recipe will not work with regular peanut butter.
  • This recipe works best with pure maple syrup. Other syrups may work but they will likely need a watery consistency like maple syrup. I've tried it with honey and the dough does not thicken the same way.
  • These cookies are only lightly sweetened. They are similar to biscuit cookies though not quite as firm.
