A simple and delicious three-ingredient recipe to make peanut butter cookies.  Using pantry items that include sugar, peanut butter and an egg.  Quick, easy and about 30 minutes to make.


1 level cup peanut butter
1 cup white granulated sugar
One egg


Preheat that oven to 350 degrees. Cookies bake in 10 to 12 minutes.

Add the above ingredients into a bowl.

Stir well to combine.

This recipe makes about 15 to 18 cookies for me. Good-sized cookies too!

I dip my fork in a little sugar when I use it to press the cookies and create the traditional crisscross pattern. This gives you that little sugar crunch on top.

Bake 10 to 12 minutes, until just starting to brown on the bottom.

If you would like to add chocolate chips to some of your cookies, just add them onto the dough balls before you flatten them.  It's the easiest way to make just a few chocolate chip peanut butter cookies!

Place on a wire rack to cool and then enjoy!


This is a small enough batch that I sometimes make it in my toaster oven!   If you want to try that, decrease the heat to 325 and watch carefully to see when they are done - they often are done a couple of minutes earlier.

Optional - add chocolate chips if desired.
