Ingredients You’ll Need
This recipe uses simple, wholesome ingredients you might already have in your pantry. Here’s what you’ll need to gather:
- Oat Flour: You can buy pre-made oat flour or easily make your own by blending rolled oats until they reach a fine, flour-like consistency.
- Creamy Peanut Butter: A standard creamy peanut butter like Jif or Skippy works best. Avoid natural peanut butters that require stirring, as they can alter the texture.
- Light Brown Sugar: This adds moisture and sweetness, contributing to the perfectly chewy texture.
- Unsalted Butter: Make sure it’s softened to room temperature for easy creaming.
- Egg: One large egg acts as a binder and adds richness.
- Vanilla Extract: A splash of pure vanilla extract enhances all the other flavors.
- Baking Soda: This helps the cookies rise and spread just the right amount.
- Salt: A pinch of salt balances the sweetness and brings out the peanut butter flavor.
How to Make Oat Flour Peanut Butter Cookies Step-by-Step
Ready to bake? This simple process will have fresh cookies on your cooling rack in no time. Follow these steps for perfect results.
- Preheat and Prep: Start by preheating your oven to 350°F (175°C). Line two large baking sheets with parchment paper to prevent sticking.
- Cream Butter and Sugar: In a large mixing bowl, beat the softened butter and light brown sugar together with an electric mixer until the mixture is light and fluffy. This usually takes about 2-3 minutes.
- Add Wet Ingredients: Add the peanut butter, egg, and vanilla extract to the bowl. Continue to mix until everything is well combined and smooth.
- Combine Dry Ingredients: Sprinkle the oat flour, baking soda, and salt over the wet ingredients. Mix on low speed until just combined. Be careful not to overmix the dough.
- Scoop the Dough: Use a medium cookie scoop (about 1.5 tablespoons) to portion the dough. Roll each portion into a ball and place it on the prepared baking sheets, leaving about 2 inches between each cookie.
- Create the Criss-Cross Pattern: Gently press down on each cookie with the back of a fork, creating the classic peanut butter cookie criss-cross pattern.
- Bake to Perfection: Bake for 10-12 minutes, or until the edges are lightly golden brown. The centers will still look slightly soft.
- Cool and Enjoy: Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
Tips for the Best Chewy Cookies
Want to guarantee your Oat Flour Peanut Butter Cookies turn out perfectly every time? Follow these simple but effective tips.
- Don’t Overbake: The key to a chewy cookie is to pull it from the oven when the center still looks a little underdone. They will continue to bake on the hot pan.
- Use Room Temperature Ingredients: Softened butter and a room temperature egg will mix together more evenly, creating a smoother and more uniform dough.
- Chill the Dough (Optional): If your dough feels too sticky, chilling it for 30 minutes can make it easier to handle and can result in less spreading.
- Measure Flour Correctly: If using store-bought oat flour, spoon it into your measuring cup and level it off. Don’t pack it in, as this can lead to dry cookies. If you loved this easy treat, you will also enjoy these 3 Ingredient Banana Brownies.
Fun Variations to Try

- Chocolate Chip Peanut Butter Cookies: Fold in 1 cup of semi-sweet or dark chocolate chips for a classic flavor combination.
- Extra Nutty: Add 1/2 cup of chopped peanuts for an extra crunchy texture.
- Cinnamon Spice: Mix in 1/2 teaspoon of ground cinnamon with the dry ingredients for a warm, spicy note. If you enjoy wholesome baked goods, check out this Healthy Oatmeal Apple Cake.
