Ingredients

• 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
• 1/2 teaspoon baking soda
• 1/4 teaspoon salt
• 1/2 cup chopped peanuts (optional)

Step-by-Step Instructions

Step 1: Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.

Step 2: In a large mixing bowl, cream together the softened butter, peanut butter, brown sugar, and granulated sugar until light and fluffy. This should take about 2-3 minutes with an electric mixer.

Step 3: Beat in the egg and vanilla extract until well combined. The mixture should be smooth and creamy.

Step 4: In a separate bowl, whisk together the oats, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, mixing until just combined.

Step 5: If using chopped peanuts, fold them into the cookie dough at this stage.

Step 6: Using a cookie scoop or tablespoon, drop rounded balls of dough onto the prepared baking sheets, spacing them about 2 inches apart.

Step 7: Bake for 10-12 minutes, or until the edges are golden brown and the centers are set. The cookies will continue to firm up as they cool.

Step 8: Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.

Expert Tips

For the chewiest cookies, don’t overbake them. They should look slightly underdone when you remove them from the oven – they’ll continue cooking on the hot baking sheet. If you prefer crispier cookies, bake for an additional 1-2 minutes.

Using natural peanut butter? Make sure to stir it well before measuring, as the oil tends to separate. For extra flavor depth, try using a combination of creamy and crunchy peanut butter. These cookies pair wonderfully with our one-bowl oatmeal cookies for a cookie platter variety.

The dough can be refrigerated for up to 3 days or frozen for up to 3 months. This makes it easy to bake fresh cookies whenever the craving strikes. For more easy baking inspiration, check out our simple chocolate dessert recipes.

FAQ

Can I make these cookies gluten-free?
Yes! Simply ensure your oats are certified gluten-free, as oats can sometimes be processed in facilities that also process wheat.

How should I store these cookies?
Store in an airtight container at room temperature for up to 5 days. They also freeze beautifully for up to 3 months.

Can I add chocolate chips?
Absolutely! Add 1/2 cup of chocolate chips along with the oats for a delicious variation. For more chocolate dessert ideas, try our rich chocolate sheet cake.

Why are my cookies spreading too much?
This could be due to butter that’s too soft or warm oven temperature. Make sure your butter is softened but still cool to the touch, and check your oven temperature with an oven thermometer.
