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 healthy 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.


  • 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.
