Peanut Butter Oatmeal Cookies

When I was a kid, peanut butter cookies were a standard of care around our house. We made them, from scratch, at least once a month. There is something so nostalgic about those thick, chewy cookies with the crosshatch pattern made with a fork before baking.

These peanut butter cookies are those classic lunchbox staple cookies you remember, with a twist – I added oats and chopped peanuts for texture, and they are so good! Chewy on the inside and crispy on the outside for an irresistable peanut butter-y treat.

HOW TO MAKE OATMEAL PEANUT BUTTER COOKIES

Peanut Butter cookies are pretty simple and straightforward, and these Peanut Butter Oatmeal Cookies are no exception.

1. Like any good cookie recipe, they start with creaming together butter and sugar. I use a combination of brown and white sugar, but brown sugar will give a warmer flavor and you could certain go with all brown if you like. Mix an egg and a dash of vanilla into the creamed butter and sugar.
2. The dry ingredients (flour, salt, baking soda, oats) are mixed separately then added to the wet ingredients and mixed together just until the dry ingredients are no longer visible. Over-mixing causing the dough to produce too much gluten and results in a dry and crumbly cookie.
3. As with sugar cookies, this dough is best when chilled, so you’ll want to factor in at least 2 hours of refrigerator time before baking. Roll into balls and bake the peanut butter oatmeal cookies at 350 degrees for about 10 minutes.

WHAT DOES IT MEAN TO CREAM BUTTER AND SUGAR?

To cream together means simply to combine butter together with sugar(s) until the mixture is light in color and fluffy in texture. It is possible to overmix – the butter will separate and you’ll have to start over so pay attention to the time. Creaming can be done by beating the ingredients together with a wooden spoon by hand if you want to build some arm muscle, or with a stand or hand mixer. It takes 2-3 minutes to cream together butters and sugars.

PRO TIP: Invest in a set of cookie scoops in various sizes.  They are affordable and they are super handy for portioning cookies, cupcakes and muffins.

CAN I USE MARGARINE IN PLACE OF BUTTER?

For most cookies a butter substitute contains water and can actually cause a crumbly texture instead of a soft and chewy one. The lack of fat is the culprit, so be sure that you always have real butter on hand when you plan to bake.

STORAGE

• Fridge: Peanut Butter Oatmeal Cookies will remain fresh for 4-5 days if stored at room temperature in an airtight container.
• Freezer: This cookie is also great for freezing! Make a double batch so you’ll always have some on hand. Store in an airtight freezer container or plastic freezer bag for up to 6 months for optimal freshness. Thaw at room temperature.
