Yield:

1 dozen cookie sandwiches

It’s hard to eat just one of these peanut-butter sandwich cookies, they're that good. Anyone who loves peanut butter oatmeal cookies will be smitten as these treats sandwich two of their favorite cookies with a rich peanut-butter filling. Adding oatmeal to the mix gives them a more robust texture and a subtle contrast to the peanut butter flavor. These cookies aren’t a copycat recipe of any store-bought treats—they’re just better! They’re sweet, salty, and chewy with crisp edges for contrast. Enjoy them with a glass of milk or a cup of coffee.

23 Types of Cookies You Should Know How to Make

When making these cookies and their filling (or any peanut butter cookie), do not use natural or homemade peanut butters as they vary in consistency and can be more oily.

Make-Ahead Methods

Refrigerate: Make the cookie dough and refrigerate it for two to three days before baking and filling the cookies.

Freeze: Take dough and freeze for up to three months. Alternatively, cut out cookies and freeze on a baking sheet; once frozen firm they can be transferred to a freezer bag and frozen for up to three months. Let dough defrost in the refrigerator and only roll and cut the cookies once it has fully defrosted.

Frequently Asked Questions

  • Why do we add oatmeal to cookie batter?

    Adding rolled oats to cookie batter adds texture, both visually and for taste, and bulk.

  • What is the origin of the sandwich cookie?

    The origins of the sandwich cookie are shrouded in mystery (or sugar!); like many popular foods, they seem to have been everywhere all at once. Different cuisines have their own takes on this popular cookie type, like the stroopwafel in the Netherlands and alfajores all over Latin America.

  • What is turbinado sugar?

    Turbinado sugar is a a type of natural brown sugar. It is made differently to the more common light brown or dark brown sugar, which are white sugars that have molasses added back in to make them brown (and softer). Sugars like turbinado, Sugar in the Raw, and muscovado are made in a more old-fashioned way: Partially evaporated sugar cane juice is centrifuged into sugar. Turbinado sugar has a sparkle, which makes it nice for decorating.
