Raise your hand if you love eating cookies but hate spending the time to make them! These one-bowl Snickerdoodle Bars give you all of the buttery, cinnamon flavors of your favorite cookies but save time in the kitchen by making them in an easy bar form.

These Snickerdoodle Bars are pretty much my definition of a perfect dessert for a group. Thick and chewy, they are filled with our favorite Kerrygold®  butter and have a crunchy cinnamon sugar crust on top. Each bite gives you the perfect mouthful of chewy and crunchy all at the same time. And you are able to pop them in the oven in less than 15 minutes.

Clean up is a snap and since you don’t have to wait for each pan of cookies to bake, you can move on to the other parts of your party prep and cross dessert off your list.

I’m always looking for ways to make hosting parties as easy as I can. So when I can get party worthy desserts like these Snickerdoodle Bars that are super flavorful without a lot of work, it definitely counts as a dessert win in my book.
