Why Peanut Butter Oatmeal Cookies are the Best

Peanut butter oatmeal cookies are a classic treat that never goes out of style. What makes them so irresistible is the combination of the nutty peanut flavor and the chewy texture of oats. Peanut butter is also a great source of protein and healthy fats, making these cookies a slightly healthier option than traditional cookies.

Oats, on the other hand, are a great source of fiber, which keeps you feeling full longer. I also love the chewy texture they add to the cookies that’s hard to resist. 

Another reason why peanut butter cookies are the best is that they are so versatile. You can add chocolate chips, raisins, or any other mix-ins you like to make them fit your taste preferences. They’re also perfect for any occasion, whether you’re enjoying them as an afternoon snack, serving them at a party, or giving them as a gift.

And best of all, they’re easy to make with just a few simple ingredients.

Ingredients you need to bake Peanut Butter Oatmeal Cookies

To make these chewy peanut butter oatmeal cookies, you’ll need the following ingredients:

• 3/4 cup unsalted butter, at room temperature
• 1/2 cup creamy peanut butter
• 1/2 cup granulated white sugar
• 1/2 cup packed dark brown sugar
• 2 large eggs
• 1 teaspoon vanilla extract
• 2 cups of oats (I use quick oats for cookies)
• 1 ½ cups all-purpose flour
• 1 teaspoon baking powder
• 1/4 teaspoon baking soda
• ½ teaspoon cinnamon
• 1 cup golden raisins

Step-by-step instructions for Oatmeal Cookies

Follow these simple steps to make your own batch of peanut butter oatmeal raisin cookies:

1. Preheat your oven to 375 degrees F. Line a cookie sheet with parchment paper or spray with nonstick cooking spray.
2. In a large bowl, cream the butter, granulated sugar, and brown sugar until light and fluffy. You can use an electric mixer or a stand mixer fitted with the paddle attachment.
3. Mix in the peanut butter. Then add the eggs and vanilla extract and beat until thoroughly combined.
4. In a separate medium bowl, whisk together the oats, flour, baking powder, baking soda, and cinnamon. Gradually stir the dry ingredients into the wet mixture on medium speed until just combined. Mix in the raisins.
5. Drop the cookie dough by rounded teaspoonfuls onto the prepared baking sheet, leaving about 2 inches between each cookie.
6. Bake cookies for 10-12 minutes or until the edges are golden brown.
7. Allow the cookies to cool on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely.

Tips to make perfect Peanut Butter Oatmeal Raisin Cookies

To make the ideal peanut butter oatmeal cookies, here are a few tips to keep in mind:

• Use room temperature butter: Room temperature butter will cream more easily with the sugar, resulting in a lighter and fluffier cookie.
• Don’t overmix the dough: Overmixing the dough can result in tough cookies. Mix the ingredients until just combined.
• Chill the dough: Chilling the dough for at least 30 minutes before baking can help prevent the cookies from spreading too much in the oven. This step isn’t required, but it helps you get the perfect cookie!
• Use parchment paper: Using parchment paper to line your baking sheet will prevent the cookies from sticking and make cleanup easier.

Recipe Variations

These peanut butter oatmeal cookies are delicious as is, but you can also add your own twist to the recipe. Here are a few variations to try:

• Add chocolate chips: Fold in 1/2 cup of chocolate chips to the cookie dough for a delicious chocolate peanut butter flavor.
• Use crunchy peanut butter: If you prefer a little crunch in your cookies, use crunchy peanut butter instead of creamy. You can also use natural peanut butter instead of regular peanut butter; just make sure you mix it well before using it.

Can I use old-fashioned or rolled oats instead of quick oats?

Yes, you can use old-fashioned oats. Keep in mind that the texture of the cookies will be slightly different.

Can I use margarine instead of butter?

Yes, you can use margarine instead of butter. Just make sure it’s at room temperature.

How do I store leftover Peanut Butter Oatmeal Cookies?

To keep your cookies fresh, store them in an airtight container at room temperature for up to 5 days.

Can I freeze peanut butter oatmeal cookies?

Yes, you can freeze peanut butter oatmeal cookies. Allow them to cool completely, then store them in an airtight container or freezer bag for up to 3 months. Thaw them at room temperature before serving.
