Homemade Oatmeal Buttercream Pies. These are so soft and chewy on the inside and buttery crisp on the outside. Perfect little sandwich cookies!

This summer I was at a Fourth of July party at my neighbors. After we’d finished eating, and were sitting around the table chatting — completely stuffed from the usual, delicious Fourth of July fare — another neighbor walked in, dropped off a plate of cookies and said:

“Here. I had to get these out of my house. They were too dangerous.”

Well, like a moth to the flame, I immediately was drawn to these cookies and had to see for myself.

A cookie? Too dangerous? That has my name all over it.

I was completely stuffed, so I just cut one in half for a little taste.

But one bite of these devilish cookies and I knew I was a goner.

Don’t be fooled by their innocent little oatmeal cookie appearance. They’re unlike anything I’ve ever had before. Basically, these cookies are EVIL.

Of course I immediately went back and retrieved the other half and devoured it. The cookie made me do it.

They are insanely good. The perfect oatmeal cookie. Decadently buttery and chewy on the inside with perfect oatmeal-crisp edges. And stuffed with buttercream frosting.

I immediately asked for the recipe and my neighbor was happy to share.

And today, I am deviously delighted to pass on the recipe to you.

Two tablespoons of heavy cream (or milk).

And one teaspoon of vanilla extract. I always use Tahitian vanilla in recipes that don’t call for baking, like frostings and ice cream. It really does add a WOW factor that people can immediately recognize. It’s my secret ingredient. Try it sometime! :) But it’s susceptible to heat, so don’t bake with it.

Beat this on medium speed until light and fluffy, about 2-3 minutes. Love how smooth and shiny it is!
