Ingredients You’ll Need
- 1 cup creamy peanut butter
- 1 cup old-fashioned rolled oats
- 3/4 cup brown sugar
- 1/2 cup granulated sugar
- 1/2 cup unsalted butter, softened
- 1 large egg
- 1 teaspoon vanilla extract
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1/2 cup chopped peanuts (optional for extra crunch)
Step-by-Step Instructions
Step 1: Prepare Your Ingredients
Start by preheating your oven to 350°F (175°C). Line two baking sheets with parchment paper. Make sure your butter is properly softened to room temperature for easy mixing.
Step 2: Cream the Butter and Sugars
In a large mixing bowl, beat the softened butter with both brown and granulated sugars until light and fluffy. This should take about 2-3 minutes with an electric mixer. The creaming process incorporates air into the dough, helping your cookies rise beautifully.
Step 3: Add Wet Ingredients
Beat in the peanut butter until well combined, then add the egg and vanilla extract. Mix until everything is fully incorporated and the mixture is smooth.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the oats, baking soda, and salt. Gradually add this dry mixture to the wet ingredients, mixing just until combined. If you’re using chopped peanuts, fold them in at this stage.
Step 5: Form the Cookies
Using a cookie scoop or tablespoon, drop rounded balls of dough (about 1.5 tablespoons each) onto your prepared baking sheets, leaving about 2 inches between each cookie. You can gently flatten them slightly with the back of a spoon if you prefer thinner cookies.
Step 6: Bake to Perfection
Bake for 10-12 minutes, or until the edges are golden brown but the centers still look slightly soft. The cookies will continue to set as they cool. For chewier cookies, bake for the shorter time; for crispier edges, bake a minute or two longer.
Step 7: Cool and Enjoy
Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely. This resting time helps them set properly without falling apart.
Expert Tips for Perfect Cookies
Don’t Overmix: Once you add the dry ingredients, mix just until combined. Overmixing can lead to tough cookies.
Chill the Dough: For thicker, chewier cookies, chill the dough for 30 minutes before baking. This prevents excessive spreading.
Quality Peanut Butter Matters: Use natural creamy peanut butter for the best flavor. Avoid using reduced-fat varieties as they can affect texture.
Customize Your Cookies: Add chocolate chips, raisins, or even a sprinkle of cinnamon to make these cookies your own signature treat.
