Peanut Butter Buttercream Frosting

I’m not allowed to bake cookies anymore.

Especially not cookie cakes.

Definitely not cookie cakes.

They’re like potato chips for me. I can’t have just one!

Each time I walk by the kitchen, I have to have a small bite. Or a slice. Or a giant face-full of deliciousness.

Don’t get me wrong, if I’m out and about and a cookie so happens to land itself in my vicinity, well then I’m allowed to enjoy it. [duh. ‘merica!] However, I’m not allowed to make them. I’m also not allowed to make this frosting. While there’s plenty of room in my lifestyle for indulgence, there isn’t room for recipes that drive me to eat an entire bowl of frosting with a spoon.

You’ve been warned.  Make this at your own risk…

Silly me.  Did I mention it’s really stinkin’ good on cookies?
I’m hopeless.

Author Jenn Laughlin - Peas and Crayons


  • 1/4 cup salted butter, softened
  • 1/4 cup peanut butter (I'm a sucker for skippy natural)
  • 1.5 cups powdered sugar
  • 1/4 cup milk (coconut milk, almond milk, or regular milk)


  1. Allow butter to soften to room temperature.

  2. Use a handheld electric beater to whip the above ingredients into a fluffy, flavorful frosting. The thickness and sweetness can be adjusted to taste by beating in extra powdered sugar at the end, if desired, but the ratio above was my version of peanut butter perfection!

  3. Frost yourself!

As for the cookies?  Simply bake up [this] homemade cookie cake at home and go nuts with your favorite cookie cutter.

If you’re a cookie cutter hoarder like myself, you can actually bake the cookies inside the cookie cutters as well!  It’s the same method as my chocolate peanut butter hearts or snowflake bark.  Press the cookie dough into the cutters, line them up on a baking sheet and bake to golden cookie perfection.  It’s seriously that easy.

I have it on pretty good authority that it tastes AMAZING on my small-batch chocolate cupcakes too!

You can also slather this frosting in between two freshly baked chocolate chip cookies, sandwich style.  Who needs bread anyways?

So delicious.

So dangerous.
