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.

FAQs

How do I know if my peanut butter cookies are done? ›

Unlike many other cookies, peanut butter biscuits only fully harden once they've been removed from the oven. Here's how to tell when peanut butter cookies are done: The tops of the cookies are a uniform light brown. They're soft to the touch but not moist or mushy.

Why are my peanut butter cookies always hard? ›

If your peanut butter cookies are hard, you likely cooked them for too long. They should not be baked for more than 8 or 9 minutes.

How can you tell if a cookie is baked properly? ›

Watch for cookies that still have a doughy or unbaked look. Texture: Touch the surface of the cookies gently. They are likely not fully cooked if they feel excessively soft or doughy. Properly baked cookies should have a slightly firm texture on the outside.

Why do you put fork marks on peanut butter cookies? ›

So it looks like that there are utilitarian reasons for the cross-hatching—to allow for even cooking—but it might have been passed along for nearly a hundred years for primarily aesthetic reasons, where the cross-hatching is more to identify the cookies as peanut butter ones, rather than to cook them well.

What to do if cookies are underbaked? ›

But this doesn't have to be the end for your underdone cookies, simply return them to the oven for a second round of baking. The purpose of this second bake is for the heat to permeate the center of your baked goods and even their textures.

What happens if you don't flatten peanut butter cookies? ›

If you don't flatten the cookies first, then the fork does double duty – it performs both functions. One very subtle result of creating the pattern is that the little tips of dough bake up crisper than the rest of the cookie, giving you both a bit of additional texture and deeper taste where the dough is more baked.

What to do if peanut butter cookies are too soft? ›

If the dough seems too soft, chill it for 10 to 15 minutes before baking. Use shortening instead of butter or a combination of the two if you don't want to sacrifice that buttery flavor. The dough was too wet. Using the wrong size egg could also add extra liquid, resulting in too much spreading.

How do you make peanut butter cookies soft again? ›

The easiest way to soften cookies with bread is to place the cookies in an airtight container with a slice of bread and leave them for a few hours. The bread will release moisture and help to rehydrate the cookies, making them soft and chewy once again.

How do you fix dry peanut butter cookies? ›

Dry – “Dry” or “Crumbly” dough is a product of over-mixing or using too much of any ingredient during the mixing process. This can be reversed by adding one to two tablespoons of liquid (water, milk or softened butter) to your mix.

Can you re-bake undercooked cookies? ›

I am going out on a limb against popular opinions by saying, YES, it's okay to place your under baked or underdone cookies back into the oven for a second bake.

Should you bake cookies at a higher or lower temperature? ›

For those ooey, gooey chocolate chip cookies, 375 degrees Fahrenheit is your sweet spot. It's the perfect temperature to ensure super crispy exterior edges, while leaving the center slightly underdone and, thus, doughy and fudgey. If you're feeling particularly bold, give 400 degrees Fahrenheit a go.

Should you refrigerate peanut butter cookie dough before baking? ›

The dough is extremely soft due to the creamy peanut butter, eggs, and butter and if it's not cold going into the oven, the cookies will spread all over your baking sheet. I chilled this cookie dough for 24 hours and my cookies were soft, thick perfection. I recommend chilling the dough for at least 3 hours.

Why do my peanut butter cookies not taste like peanut butter? ›

The most common mistake with peanut butter cookies is using the wrong type of peanut butter. The BEST peanut butter for today's cookies is a processed creamy peanut butter, preferably Jif or Skippy.

Why are my peanut butter cookies dry and crumbly? ›

If you're wanting to use natural (no sugar added) peanut butter, the cookies will be less sweet and they will likely spread out more. Using natural peanut butter will change the structure and texture of the cookies. Why are my cookies dry and crumbly? This is most likely a classic case of using too much flour.

Is shortbread meant to be soft when it comes out of the oven? ›

Is shortbread supposed to be soft when it comes out of the oven? Yes, upon cooling it will firm up. Shortbread should have a soft and tender texture but be slightly crisp when you bite into it.

How do you check if cookies are done without a toothpick? ›

We know you've got a knife in your kitchen already, which is one reason it's our favorite alternative to toothpicks, but there are additional options. Thin bamboo skewers. Wooden skewers you might use for grilling are a little thicker than toothpicks, but they'll work just fine for a cake test.

Do cookies harden when they cool? ›

If the dough is shiny as it bakes (thanks to the butter or other fat in it), that shine will significantly reduce or go away once the cookies are set. As soon as they reach that stage, remove them from the oven. Even if they don't feel firm yet, they'll continue to set and harden as they cool.

Is it okay to eat undercooked cookies? ›

When making cookies, brownies, cakes, or bread, you might be tempted to taste a bite before it's fully baked. But you can get sick after eating or tasting raw (unbaked) dough or batter.
