You Can’t Go Wrong With Old Trusty

As you know, I have a cookie obsession. And because of that, there’s a lot of cookie bakin’ going on at my house. All. The. Time. Almost every day I’m working on something.

But when it comes to baking a cookie treat for my family, I almost always resort to old trusty. These 3 ingredient peanut butter cookies are just that, an old, trusted, often-baked recipe that produces the perfect soft, crunchy, chewy, and completely delicious peanut butter cookies in literally, no time at all.

The 3 Ingredients You’ll Need

  • Your favorite peanut butter
  • Sugar
  • An egg

It’s hard to believe that’s all you need to have a soft, chewy, bursting with peanut butter flavor (and did I mention, gluten-free?) batch of cookies, but really, that’s it.

How to Make These 3 Ingredient Peanut Butter Cookies

  1. In a medium bowl, combine the peanut butter, sugar, and egg and mix until smooth.
  2. Then, using a 1.5 TBS cookie scoop, scoop them onto a lined baking sheet.
  3. Use a fork to gently press down on the top of each cookie in a criss-cross pattern.
  4. Generously sprinkle the tops of each cookie with sugar (which is optional, but I mean why wouldn’t you?).
  5. Then, just throw them in the oven and bake for 10 minutes (not literally, of course – please don’t throw the cookies. That will most certainly end up being a big mess and you’ll end up with no cookies…and no-one wants that!).

A Note about the Dough

This cookie dough is pretty sticky, so be mindful when you’re pressing the tops down with the fork. It’ll likely stick to the top of the cookie and you’ll need to gently hold onto each cookie to remove the fork. This is totally normal.

Fun Variations of 3 Ingredient Peanut Butter Cookies

  • Add 1/2 tsp of vanilla extract and 1/4 tsp sea salt to the dough to enhance the favor of the cookies.
  • Drizzle the tops of the cookies with chocolate or white chocolate.
  • Or dip the cookies in your favorite variety of melted chocolate.
  • Substitute half crunchy peanut butter for added texture.

Questions About This Recipe

These cookies don’t brown much, so it’s really hard to tell. Usually right about 10 minutes in, they’ll be slightly puffy and that’s when you’ll want to pull them out.

You definitely don’t want to over-bake these cookies, they get very dry and crumbly and aren’t nearly as good; I would err on the side of under-baking them.

Yes! This recipe is great for doubling, but keep in mind the cookies are best in the first few days, so if you have a lot leftover, make sure to freeze them.

I find that regular peanut butter works best in this recipe because of the consistency, but I have used Jif Natural with great success.
