Ingredients needed

What makes this peanut butter oatmeal cookies recipe so special? Aside from being super easy to make, the ratio of ingredients create a soft, chewy, with a slightly crispy edges and melt-in-your-mouth center that hold together well cookie! Here’s everything you’ll need to make them:

  • Peanut butter. Use a processed brand of creamy peanut butter, like Jif or Skippy, as it will give you the most consistent results for baking. We haven’t tried crunchy peanut butter, but it should work.
  • Sugar. To keep the cookies softer and chewier in the middle, yet still allow for crispy, delicious edges, we’re using mostly brown sugar. We like dark brown sugar because it contains more molasses, which adds lovely flavor. However, light brown sugar works fine, if that’s what you have.
  • Butter. We recommend unsalted butter, as opposed to salted butter, for better control over the saltiness of the recipe. Soften it to room temperature before beginning the recipe, which means it’s still cool to the touch. When you press it, your finger will make an indent. It won’t sink down into the butter or slide all around.
  • Eggs. Two eggs will add structure, stability, and richness.
  • Flour. This recipe uses all-purpose flour for the perfect tender texture. We do not recommend swapping flours.
  • Baking essentials. Vanilla, baking soda and salt are all used to ensure these taste amazing and bake up perfectly!
  • Quick oats. Instead of old fashioned oats, use quick oats in this recipe, so as not to overwhelm the chewiness with too much texture. We want these cookies to be more flat with incredible chew, not a thick, hearty rolled oat cookie.

How to make this recipe

  1. Prep. Preheat the oven to 350 degrees F (175 degrees C).
  2. Combine wet ingredients. Beat peanut butter, sugars, and butter in a large mixing bowl with a hand mixer or stand mixer, fitted with a paddle attachment, on medium speed until smooth and creamy. Beat in vanilla and eggs, one at a time, until well blended.
  1. Whisk together dry ingredients. Combine flour, baking soda, and salt in a separate medium bowl.
  1. Combine flour mixture with wet ingredients. On low speed, gently stir the flour mixture into the creamed ingredients until well incorporated, without over-mixing. Stop the mixer while beating the batter and scrape the bottom and sides of the bowl with a rubber spatula to help mix it properly. Mix in oats until just combined.
  1. Chill. Place dough in the fridge and chill for at least 30 minutes. Then, drop tablespoonfuls of dough onto cookie sheets lined with parchment paper or a silicone baking mat. We like using this cookie scoop.
  1. Bake. Place the pan with the cookie dough balls in the preheated oven, and bake until just lightly browned, 9 to 11 minutes. Do not over-bake, but allow cookies to bake long enough to get lightly golden brown on top and bottom, so when they cool they’re super chewy. 
  2. Cool. Remove from the oven and immediately add a sprinkle of flaky sea salt, if you’d like. Allow to cool on baking sheet for 5 minutes before transferring to wire racks to cool completely.

Expert tips

A few tips so these are absolutely perfect!

  • Measure your flour correctly. To avoid dry and dense cookies, it’s best to measure ingredients, and especially flour with a food scale. If you don’t have one, fluff the flour with a spoon, and add it to a measuring cup (don’t pack or scoop). Then, without shaking the cup, use the straight side of a butter knife to level the flour.
  • Use room temperature ingredients. Room temperature butter and eggs will mix more easily with the other ingredients, and result in an overall better texture. The butter should still be cool to the touch and have a temperature of about 65ºF. It should indent slightly when you press on it with your finger. Take butter and eggs out of the refrigerator about 1 hour before beginning your recipe. Here’s a guide on how to soften butter quickly if you forget to take it out of the fridge.
  • Bake on parchment paper or a silicone mat. Baking on parchment paper or silicone baking mats is recommended. Greasing the pan adds extra oil, which can cause the cookies to spread too much. Silicone baking mats will grip onto the bottom of your cookies to prevent them from becoming too flat. The mats also promote even browning.
  • Don’t over-bake. For the best soft and chewy texture, be sure to take these out of the oven around the 9 to 11 minute mark, and when the edges are set but the middles are still soft. They will continue baking on the baking sheet after being removed from the oven. 

Recipe tip

To bring eggs to room temperature quickly, simply place the eggs in a bowl of warm water (not piping hot!) for 10-15 minutes. You can do this while you’re gathering all of the other ingredients.

Frequently asked questions

Why are my peanut butter cookies dry?

Peanut butter cookies can turn out dry due to using too much flour. It’s crucial to properly measure the flour in this recipe, as even 1 extra tablespoon of flour can completely change the structure of the cookies. This is why we recommend using a food scale when measuring ingredients for baking.

Do you have to refrigerate peanut butter cookie dough before baking?

For these oatmeal peanut butter cookies, we recommend chilling the dough for at least 30 minutes, and a couple of hours to overnight is even better. When your dough is refrigerated, the butter hardens. So, when baked, they spread less and hold their shape better. This creates a soft, chewy cookie with better consistency.

Should I use baking powder or baking soda for cookies?

According to allrecipes.com, baking soda will usually create chewy cookies, while baking powder is generally used for light and airy cookies. Since baking powder is comprised of a number of ingredients (baking soda, cream of tartar, cornstarch, etc.), using it instead of pure baking soda will affect the taste of your cookies. In this recipe, we’re using baking soda for perfectly chewy cookies.

Variations

We love this cookie recipe as-is, but feel free to experiment with different mix-ins!

  • Nut butter. Change the flavor and try a different type of peanut butter, like maple or honey-roasted. You could even use almond butter or cashew butter to accommodate dietary needs. However, we do not recommend a no-stir nut butter for this recipe, as they are too runny.
  • Add-ins. This is a great base recipe to fold in chocolate chips, mini M&M’s, white chocolate chips, chopped nuts, cranberries and/or raisins. Experiment to find your favorite combination! I wouldn’t add any more than about 1 cup (180g) of add-ins. 
  • Spices. To give these a warm flavor boost try mixing in 1 to 2 teaspoons ground cinnamon.
  • Flaky sea salt. We love sprinkling a small amount of flaky sea salt to freshly baked cookies. It enhances the overall flavor and is a nice contrast to the sweetness.

Storage recommendations

  • Storing leftovers. These will keep fresh for up to 7 days, stored in an airtight container at room temperature.
  • Freezing. Baked cookies or unbaked cookie dough balls freeze well for up to 3 months. Bake frozen cookie dough balls for an extra minute, no need to thaw. To freeze the cookie dough balls, place in the fridge for 1 hour. Then, place the solid and cold dough balls into a freezer bag. Label the bag with the month and the baking temperature and store in the freezer.

Author: Kim

Ingredients

  • 1 cup (250g) peanut butter*
  • 1 cup (200g) packed brown sugar
  • ¾ cup (150g) granulated sugar
  • 1 cup (2 sticks or 230g) unsalted butter, softened
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • 1 ½ cups (188g) all-purpose flour, spoon & leveled
  • 2 teaspoons baking soda
  • 1 teaspoon salt
  • 2 cups (160g) quick-cooking oats

Instructions 

  • Preheat the oven to 350 degrees F (175 degrees C).
  • Beat peanut butter, sugars, and butter in a large bowl with an electric mixer on medium speed until smooth and creamy. Beat in vanilla and eggs, one at a time, until well blended.
  • Combine flour, baking soda, and salt in a separate bowl. On low speed, gently stir the flour mixture into the creamed ingredients until well incorporated, without over-mixing. Stop the mixer while beating the batter and scrape the bottom and sides of the bowl with a rubber spatula to help mix it properly. Mix in oats until just combined.
  • Chill for at least 30 minutes. Then, drop tablespoonfuls of dough onto cookie sheets lined with parchment paper or a silicone mat.
  • Bake cookies in the preheated oven until just lightly browned, 9 to 11 minutes. Do not over-bake, but allow them to bake long enough to get lightly golden brown on top and bottom, so when they cool they're super chewy.
  • Remove from the oven and allow to cool on baking sheet for 5 minutes before transferring to a wire rack to cool completely. Store in an airtight container at room temperature for up to 1 week.

Notes

*Use a non-natural peanut butter like Jif creamy or Skippy creamy. I do not suggest using natural style or oily peanut butter as both produce crumbly, fragile, and sandy tasting cookies.
  • Storing leftovers. These will keep fresh for up to 7 days, stored in an airtight container at room temperature.
  • Freezing. Baked cookies or unbaked cookie dough balls freeze well for up to 3 months. Bake frozen cookie dough balls for an extra minute, no need to thaw. To freeze the cookie dough balls, place in the fridge for 1 hour. Then, place the solid and cold dough balls into a freezer bag. Label the bag with the month and the baking temperature and store in the freezer.
