World’s easiest peanut butter cookies!

My mother-in-law made these peanut butter cookies for us when we were visiting over Easter, and I think I ate five in one go. They are delicious! So moist and chewy and crazily addictive. And the best bit? They consist of only THREE INGREDIENTS! How simple is that?!


-1 cup of peanut butter
-1 cup of brown sugar
-1 egg

In a large bowl, mix the three ingredients together until you have a smooth, consistent dough. Using your hands, roll dough into small balls and place on a baking tray, evenly spaced. Press a fork into the dough balls in opposite directions making a criss-cross pattern. Then bake at 350° F (175° C) for 8-10 minutes. And that’s it. So easy!! I’m planning on making them for my mom when she comes to visit — she can’t eat gluten, but loves cookies. She is going to be so excited about this recipe!

And here’s a photo of sneaky Ivy stealing a warm cookie straight off the tray! Yummmm….

Hi Courtney: These look incredible. Can you use natural peanut butter instead of a Jif or Skippy type peanut butter? I worry that they might not mix up as well with the natural peanut butter that we typically use for sandwiches. Thanks in advance!

Hi Karen,
I used a natural, organic peanut butter and it worked just fine.
I will admit that my cookies weren’t quite as tasty as the ones my mother-in-law made (and she used Jif!) but maybe I just need practice. : ) xx

Just baked these and substituted half the peanut butter for raw cashew butter to make it healthier. Great recipe Courtbey. Thanks for sharing a GF cookie recipe but my hips don’t thank you 🙂

Hmmmm I want to try this with almond butter!

May 7, 2014

Just made these and they are so yummie! The only downside: they magically disappear very quickly around this house…

I wonder if these would work with almond butter? I’m not a huge fan of peanut butter. But maybe I’ll just make them for my least then I won’t eat them all, lol.

I’ve made a very similar recipe with almond butter. It totally works – they were amazing. YUM!

These were so good I made two batches in two days! My family loved, too. Also, an easy recipe is a winner for me since I have no patience at all. Thanks so much!!

I have been making these since elementary school and that is LONG time. I have found JIF and skippy work best. You can also use white sugar. Fine Baking sugar works well too. People are always so impressed with them and they are so simple! My mom is not a fan of PB but, likes these.

OMG your daughter is SO CUTE.

Just found you today via Cup of Jo, going to look around.

I’ve made these before many a times (but with white sugar 🙂 and they are always a hit! Great for potlucks too. Your pictures are beautiful, thanks for sharing!

I am so psyched to try out this brilliantly simple
Recipe! And I am smitten with your daughter’s dress with the shoulder ties! Did you make it yourself? Or if not where might it be found? Thanks for sharing!

I’ve just made these with Mr 2 (who loved to stir the ingredients) and Miss 4 (who loved to roll out the dough). The results are delicious! Thanks for sharing.

Courtney! Have been so excited to try these out and just made them! They are delicious! Thanks for sharing, xx

Instead of pressing with a fork, you can put a chocolate kiss in the middle right after they come out of the oven! I make these for Christmas cookies and they are so simple and always well received. I use fancy small PB cups in the place of the kiss, but any chocolate you prefer will do! You can also add a glob of jam!

Hi Courtney,

I did try these but they were very chewy 🙁 I’m wondering if I got the measures correct. How many grams do you think is necessary of peanut butter?

Hi Courtney,
Excellent recipe. Just made them today.
We used dutch brand Calve peanut butter.
Yummy. After 4 hours everything’s gone.

They’re great with a bit if cocoa too and if you want them fructose free, you can substitute the sugar for a tiny bit of rice malt syrup-yum and much better for you and your kids.
