The cookies are made with 3 ingredients for starters.

Do you think you can guess what they are (without peeking)

I handed out these cookies to many and it was funny to hear all the ingredients everyone came up with except ONE.

The frosting is made with 4 ingredients and it’s so yummy!

These truly are the easiest cookies to make and in no time you’ll be enjoying them, filled or not… you choose.

You can make these cookies any size you like, they bake up quickly.

I made mini cookies about the size of a quarter. I scooped the dough and used about a teaspoon of dough, rolled it into a ball and then pressed a fork in the dough twice, crossing the marks to make a typical press into a peanut butter cookie. I used a tablespoon and two tablespoons for the larger cookies.

Now it’s no surprise I like salty-sweet desserts and this is no exception.

Some people like their peanut butter cookies sprinkled with sugar,

me… I like salt. I use coarse kosher salt and they are irresistible!

The filling on these cookies is peanut butter frosting, it’s amazing!

It’s easy to whip up and it only takes a couple of minutes to fill a piping bag with a star tip and add to the cookies to make sandwich cookies.

The ingredients you’ll need for these cookies are

  • peanut butter
  •  sugar

Do these taste like cookies if there is no flour in them?

Yes, they taste just like cookies with flour. Peanut butter is amazing that way!

Are these cookies crunchy or chewy?

These cookies have a great crunch to them, but they are not dry. They bend some when broken in half so they are a great combination fo crunchy and chewy together.

What can I fill these cookies with to make them into sandwich cookies?

I have a recipe below for a peanut butter filling, you could easily use chocolate frosting, or chocolate ganache, or even a strawberry flavored buttercream frosting, or spread some jam in between these cookies to taste like a PBJ!
