Ingredients & Substitutions

This section explains how to choose the best ingredients for oatmeal chocolate chip peanut butter cookie, what each one does in the recipe, and substitution options. For measurements, see the recipe card below.

Creamy Peanut Butter – For the best results, use room temperature, well-mixed, thick peanut butter. I prefer this brand, which is just as thick as conventional but has no added sugar. Runny peanut butter might still work, but the texture of the cookies may be a bit different. If your peanut butter is unsalted, add 1/4 teaspoon of sea salt to the dough.
Coconut Sugar – Adds a delicious caramel-like sweetness and natural flavor to the oatmeal peanut butter chocolate chip cookies, similar to brown sugar but it’s less refined. If you prefer a sugar-free option, you can substitute it with Besti Brown Monk Fruit Allulose Blend.
Granulated Sweetener – I use Besti Monk Fruit Allulose Blend as a natural sweetener and my kids can’t tell the difference at all. Regular granulated sugar also works, it’s just not what I usually recommend.
Avocado Oil – I haven’t tested it, but these peanut butter oatmeal chocolate chip cookies should also work with butter or coconut oil.
Vanilla Extract – Use high quality vanilla extract for the best flavor.
Egg – Use a room temperature egg for best results. I have not tried it out with a flax egg or any other egg substitute, but these should work.
Baking Soda – Helps the cookies rise and become soft and chewy.
Sea Salt
Rolled Oats – You can try using quick oats if you want to, but avoid using steel-cut oats, as their texture is too different.
Chocolate Chips – You can use milk chocolate chips, dark chocolate chips, white chocolate chips, or semisweet chocolate chips depending on whether you prefer more sweet or more chocolaty. I used sugar-free dark chocolate chips.

Optional Add-Ins:

You can replace up to 2 tablespoons of the oats with pumpkin seeds, whole flaxseeds, chopped pecans, walnuts, or dried fruit, such as dried cranberries or raisins. You can also top with flaky sea salt right after baking.

How To Make Peanut Butter Oatmeal Chocolate Chip Cookies

This section shows how to make oatmeal chocolate chip cookies with peanut butter, with step-by-step photos and details about the technique, to help you visualize it. For full instructions, including amounts and temperatures, see the recipe card below.

Mix the base. In a large bowl, stir together the peanut butter, both sweeteners, oil, and vanilla. Stir in the egg, baking soda, and salt. (You can whisk the egg before adding if you want to, but I didn’t find this necessary.)
Add the oats. Mix well. The cookie dough will be crumbly.

Add the mix-ins. Fold in the chocolate chips and any mix-ins, if desired. (I added pumpkin seeds for the version pictured below.)
Scoop the cookies. Use a cookie scoop to make cookie dough balls and place on a parchment paper-covered sheet pan. Gently flatten each dough ball into a circle about ½ inch thick.

Bake. Place the oatmeal peanut butter chocolate chip cookies in the oven and bake until the undersides are slightly browned.
Cool. Allow the cookies to cool on a wire rack to firm up.

Tips For The Best Peanut Butter Oatmeal Chocolate Chip Cookies

Although these cookies are quick and easy to make, there’s a few tips I’ve picked up along the way that make them even better:

Use room temperature ingredients. If you use very cold peanut butter or egg, the dough will seize up and the chocolate chips won’t mix well into the dough.
Dot with extra chocolate chips for prettier cookies. If you want the tops studded with chocolate, press some extras on top after flattening the cookies.
Shape after baking if needed. When you remove the cookies from the oven, you can gently shape them with a small spatula or the mouth of a large glass in case they lose some of their shape while baking.
You can make big or small cookies. Using a cookie scoop this size, it’s 2 scoops per cookie for large cookies, or 1 scoop for small cookies.
