The other day, I introduced you to the Best Peanut Butter Cookies.

And they are seriously the best peanut butter cookies.

But what can make the best peanut butter cookies even better?

How about adding a thick peanut butter filling between two cookies to make a peanut butter sandwich cookie?

It sounds a bit like a Nutter Butter, doesn’t it?

We sacrificed a few of our peanut butter cookies that we made on Saturday for this experiment.

And none of us were disappointed with our efforts. It was quite a tasty treat!

Key to Success #1 – The Filling

The filling is very thick and fluffy and oh so peanut buttery.

It starts out with mixing softened butter and peanut butter until smooth and creamy. I recommend Jif peanut butter.

This recipe would not work well with a natural type peanut butter.

Tip! Make sure your butter is not melted at all.

If your butter is melted, the filling will turn out more like the base of a peanut butter bar and will not be like a creamy cookie filling.

But now that I think of it, the filling for a peanut butter bar might be really delicious between two of the best peanut butter cookies.

Perhaps that should be our next experiment?

Emily helped me pipe the filling between the cookie layers.

We used a Wilton Cake Decorator Pro and a 1M open star piping tip to pipe the filling in a pretty swirl but that is totally optional.

There was one cookie leftover and Emily piped a mountain of filling on it. Who do you think got to eat that one?

It combines chocolate and peanut butter for a fantastic dessert.
