Why do we love this recipe so much?

It's like a checklist that goes off in my head every time I say it.

In this case, it goes: OREO (Check!), Funfetti (Check!), Cookie Bars (Check!!)

Just the sound of this sweet treat sets off all the bells and whistles in my head when I haven't even made it yet!

Now the words alone don't do it and there are lots of ways to make OREO Funfetti cookie bars, so these directions are just my personal favourite way to make this recipe come alive.

The secret to these cookie bars is the chopped-up OREO which adds better texture and integration with the Funfetti cookie batter at the same time.

Why Cookie Bars?

OREO Funfetti cookie bars are only one example of the types of things you can do with OREO cookies and Funfetti mix, but I like this way best.

First of all, for clarity, this is a from-scratch recipe (not counting the OREO cookies of course), which means that there is no Funfetti mix in the ingredients.

You make the "Funfetti" in the form of coloured sprinkles that you add to the batter while making it. 

The recipe for the batter also contains ingredients that add a bit more complexity to the palate and a very nice texture that is ideal for cutting up and serving as delicious cookie bars.

A Cute Party Treat

Because of how festive and celebratory these OREO Funfetti cookie bars are, they are perfect for serving at a party or on a celebratory dessert table.

The Funfetti like sprinkles make it the perfect component to a birthday and you can ideally use it for a New Year party as well.

Mix up the colours to customize the cookie bars for other holidays such as Christmas, Valentine's Day, and St. Patrick's Day.
