3 Ingredient Peanut Butter Cookies

These chewy, dense, Peanut Butter Cookies are an unforgettable memory from my childhood. 3 Ingredient Peanut Butter Cookies are a classic cookie; just an egg, a cup of peanut butter and a cup of sugar.

If you’re hanging out with me on Instagram, the odds are good that you’ve seen me make these at least a time or two.

Peanut Butter Cookies

After you’ve made them once, this easy peanut butter cookie recipe will be forever in your memory too. If you scan the comments on this post, you’ll see a whole lot of people calling these the Best Peanut Butter Cookies Ever.

When I was in high school, I remember stirring a batch of these cookies together with a girlfriend in the middle of the night. I was a bit skeptical that it would work, but I loved them from the first bite.

There is nothing like being able to satisfy a sweet tooth craving on a moment’s notice! We sat and nibbled on the warm cookies and talked half the night.

In less time than it takes to preheat the oven, you can have these ready and waiting to bake on a tray. There are plenty of variations here and I’ve played with the recipe a bit in the past.

In the end, I keep going back to the original. I love it for its simplicity.

The best thing about this recipe is that the kids can make these cookies without any help at all. 1 cup of peanut butter, 1 cup of sugar, and 1 egg: there really isn’t anything easier that tastes this good.

3 Ingredient Peanut Butter Cookies

While the main ingredients for the three ingredient peanut butter cookies are simply peanut butter, sugar, and an egg, feel free to change it up. Add a teaspoon of vanilla, an additional egg (for a gooier cookie – see note in recipe), a pinch of sea salt or a handful of chocolate chips.

The cookies are delicious both written or with the extra ingredients.

Please note: I do not recommend using a natural peanut butter for this recipe. I’ve found that a commercial peanut butter, i.e. Jiff or Skippy will work best for these cookies.

Cookie Baking Tips

I like to remove about 2 tablespoons of peanut butter from the “cup” listed in this recipe. This results in a slightly less dense cookie that everyone loves even more than the original.

Alternatively, some readers have mentioned that they like to add an extra egg to this recipe. If you choose to add an extra egg, simply scoop the finished cookie dough onto the baking tray.

The dough will not be firm enough to roll into balls or press with a criss-cross pattern. The cookies will be puffier straight out of the oven and then will settle a bit as they cool.
