These chocolate brownie cookies think they’re all that and a bag of chips.

Well, let’s face it.  They are.  They’re like the popular kid at school.  Everyone wants to sit by the brownie cookies at lunch.

I’ve long been a fan of brownies.  I mean, given the choice between chocolate cake or chocolate brownies, I’ll take the brownies every time.  I’ve been wanting to turn them into cookies for a while now.  I’ve been looking at how other people are doing it, and pinning some fantastic pictures of brownie cookies, and dreaming and planning until I could stand it no longer.

Kelly at Just a Taste makes such fabulous stuff all the time, and in the end it was her brownie cookie recipe that I finally decided to use.  Sort of.  I made a few changes, just to make it my own.marshmallow fluff

frosting recipes for cupcakesIsn’t it amazing how many flavors taste amazing with chocolate?  Like mint.  And peanut butter.  Caramel.  Strawberry.  Raspberry.  Blackberry.  Vanilla.  Orange.  And let’s not forget… marshmallow.

My kids get very excited when I buy marshmallow fluff.  Or “that marshmallow stuff,” as they call it.  The thing is, most marshmallow frosting recipes I’ve seen are all egg whites and sugar, like making homemade marshmallows, but I really wanted a marshmallow creme frosting.  I found a marshmallow creme frosting recipe for cupcakes, and decided to give it a whirl.

It did turn out very loose, but also very, very tasty.

If runny frosting that forces you to lick your fingers is not your thing, I recommend adding more powdered sugar, or chilling the frosting, {or frosted cookies} until you’re ready to eat them.

Personally, I like licking my fingers.
