These peanut butter oatmeal cookies are soft, chewy, and naturally gluten-free and also dairy-free! Make this recipe for a guilt-free sweet treat.

Sometimes you just need something sweet that doesn’t take too long to make. Cookies are a great option because they’re quick, easy, and delicious right out of the oven.

The best part about these homemade peanut butter cookies is that you can have an indulgent snack while also taking care of yourself. And if you are looking for more healthy cookies, check these ones out: Almond Butter Cookies Recipe, Chocolate Chunk Hazelnut Cookies, Sugar-free Nutella Thumbprint Cookies and Almond Flour Shortbread Cookies.

They were a huge hit with my family, and I bet they will be in your family, too. Why do I believe everybody will love these Healthy Peanut Butter Oatmeal Cookies? Because they are incredibly flavorful, chewy, soft, gluten-free, and healthy! Or at least healthier than the traditional cookie recipes. Honestly, I’m loving my healthier cookies like these Cranberry Almond Chocolate Chip Cookies, Low-Carb Peanut Butter Cookies, and Chocolate Almond Butter Cookies. You can hardly tell that they’re healthy.

What makes this a healthy cookie recipe?

Making these peanut butter cookies with oatmeal instead of flour results in several added health benefits.

  • Oatmeal cookies have higher amounts of fiber and minerals than those made with flour
  • Both the peanut butter and oatmeal provide some protein, which makes you feel full and give you longer lasting energy.
  • This healthy cookie recipe is a delicious way to enjoy some treats without feeling guilt about it.

How to make peanut butter oatmeal cookies

These homemade cookies are really simple to make. Just mix up the batter and bake!

  1. Make the cookie dough – Combine the dry ingredients in a small bowl. In a separate bowl, whisk together the wet ingredients until well combined. Mix the two sets of ingredients together, then fold in the chocolate chips.
  2. Bake and cool – Use a tablespoon to scoop the dough onto a lined baking sheet. Gently press down on each dough ball to flatten the top. Bake until the edges start to brown, then remove from oven. Let them cool completely before removing from the baking sheet.

INGREDIENT SUBSTITUTIONS

  • Egg-free – Replace the eggs with flax eggs at a 1:1 ratio. To make a flax egg, mix together 1 tablespoon ground flaxseed with 3 tablespoons warm water. Let sit until thickened, then use as directed. Since this recipe uses 2 eggs, you’ll need to make 2 flax eggs.
  • Dairy-free – Simply substitute the regular chocolate chips with a vegan variety. Most stores carry at least one brand, and you won’t be able to taste the difference. Doing this and replacing the eggs will also make this recipe vegan.
  • Reduced calorie – Applesauce can be used in place of the egg at a ratio of ¼ cup per 1 egg. Not only is this another way to make the recipe egg-free, but it reduces the overall fat and calories in the cookie recipe as well.

Recipe notes

  • The cookies will appear under baked when it’s time to remove them from the oven. This is normal. The heat from the baking pan continues to cook them as they cool. If you leave them in the oven until they are cooked all the way through, you’ll end up with dry, hard cookies.
  • You can use an electric mixer to make the dough instead of mixing by hand. Keep the speed on low to medium-low and mix each time until just combined. Mixing at a high speed or over mixing will result in flat cookies. If using a stand mixer, use the paddle attachment instead of the whisk.

Peanut Butter Oatmeal Cookies

These peanut butter oatmeal cookies are soft, chewy, and naturally gluten-free and also dairy-free! Make this recipe for a guilt-free sweet treat.
Prep: 10 minutes
Cook: 11 minutes

Ingredients

  • 1 cup creamy peanut butter
  • ⅔ cup coconut sugar brown sugar
  • 1½ teaspoons vanilla extract
  • 2 large eggs
  • ⅔ cup rolled oats
  • 1 teaspoon baking soda
  • ⅔ cup chocolate chips
US CustomaryMetric

Instructions

  • Preheat oven to 350ºF.
  • In a small bowl, add the oats and baking soda. Mix well until combined, and set aside.
  • In a medium bowl, whisk the peanut butter, brown sugar, eggs, and vanilla for about 5 minutes or so.
  • Add the dry ingredients into the wet ingredients bowl, and mix all together.
  • Add the chocolate chips.
  • Place a silicone mat or parchment paper on a baking sheet.
  • Scoop out 1 tablespoon of the batter onto the sheet 2 inches apart.
  • Then, flatten the top of the cookie with two fingers.
  • Bake for 9-11 minutes, and let them cool completely before removing from the baking sheet. If you don't, the cookies may break apart.
  • The cookies may look a little underdone, but they will continue to cook once you remove them from the oven.
  • Makes 16-20 cookies.

Tips

  • Adapted from Ambitious Kitchen.
  • Brown sugar can be used in place of coconut sugar if you prefer. 
  • The cookies do not naturally spread a lot, so you will have to press them down before baking.
  • I like saving a few chocolate chips to press on top of the cookies before baking so they look nicer afterwards.
  • Instead of using dark chocolates, you can substitute with other types of chocolates such as white chocolate, milk chocolate, caramel, and more!
  • To store: Store the cookies for up to a week in an airtight container in the fridge.
  • To freeze: After baking, flash freeze the cookies before transferring them to a freezer-safe bag for up to 3 months.

    So funny how countries have their various foods (like peanut butter for North America and dulce de leche for South America) that are difficult to find outside the borders. I can definitely see why you went on a peanut butter rampage when you were first introduced to it..seriously amazing stuff! Now I’m dreaming about these cookies with ducle de leche drizzled on top, ha! Love it.

      You can use Xylitol, which is a sugar alcohol used as a sweetener. It has the same texture and flavour than sugar. I’m baking with this now and it works great.

    Is there any substitute you can use instead of baking soda?

      Sorry Alexa, I really don’t know but I believe if you bake it with the baking soda it will work.

      My batter wasn’t very runny. Do you use the same amount of rolled oats I indicated in the recipe box?

    Delicious! I used a bit more oats because i underestimated the about of peanut butter i had.. i feared it would be dry so i added a splash of water. I believe the 2 eggs gave it a cake like consistency and it was sooo yummy i have to refrain from eating the whole batch!

    Tried this recipe and used peanut butter granola instead of chocolate chips.  But Definitely needs the sweetness of chips or raisins.  Quick and easy and healthy.   Will fix again.  Soft yummy cookie!  Thanks!
