Hi friends! It’s Kristine from Kristine in between again, popping over to share my favorite old-fashioned peanut butter cookie recipe with you today. Let me tell ya, they are cookie perfection! And you’ll never believe it, but these little peanut butter cookies only have 3 simple ingredients! I know – SO AWESOME!

3 Ingredient Peanut Butter Cookies in a bowl

As I’m sure you’re learning, I have a cookie problem. I do. And because of that, there is a lot of cookie bakin’ going on at my house. All. The. Time. Almost every day I’m working on something new!

But when it comes to baking a cookie treat for my family, I almost always resort to an old trusty recipe. These 3 ingredient peanut butter cookies are just that, old and trusted, as well as simple, soft, crumbly, and completely delicious!

Second to the taste and texture of these cookies, my favorite part is that the ingredients are in my pantry 100% of the time, so I can whip up a batch whenever the need (or want) arises! Oh, and they’re perfect for getting the little ones involved without making a humongous mess (one bowl and a few cookie sheets should do the trick). You’re welcome!

Peanut Butter Cookies ingredients in stages with egg, sugar and peanut butter

Egg. Sugar. Peanut butter. That’s all you need to have a soft, crumbly, bursting with peanut butter flavor (and did I mention, gluten-free?) batch of cookies! I know, I almost can’t believe it myself!

Peanut Butter Cookies Rolled on cookie sheet and then pressed with a fork

The process is simple; in a medium bowl you combine the 3 ingredients and mix until smooth. Then you just scoop them out by the tablespoon, gently flatten them with a fork, sprinkle with sugar (which is optional, but I mean why wouldn’t you???) and throw them in the oven (not literally, of course – please don’t throw the cookies; that will most certainly end up being a big mess and no-one wants that!).

And then, after a few minutes at 350 degrees, when you open the oven, you’ll find these perfectly sweet old-fashioned 3 ingredient peanut butter cookies!

Peanut Butter Cookies with only 3 ingredients

There are a few things you should know about these cookies though, so check out these tips.

Kristine’s tips for outstanding Peanut Butter Cookies:

  1. These cookies are super soft and crumbly right out of the oven. Please don’t try to eat them right away! They need a few (or more like 10 to 15) minutes on the pan before being moved. Trust me, they’re worth the wait!
  2. Yes, you can add 1 tsp of vanilla extract and/or 1/4 tsp salt to the recipe to enhance/balance the flavors, but that makes them more like 4 or 5 ingredient cookies, haha!
  3. You can also add an extra egg to make them a little chewier if you don’t prefer a crumbly cookie.
  4. Try adding a chocolate drizzle to the top of the cookies to ‘fancy’ them up a bit, which also makes them super-duper yummy! Just melt a 1/2 cup chocolate chips in the microwave and drizzle over the cookies while they are cooling on the baking sheet. But again, that’s more like 4+ ingredients. 🙂
