Little Debbie Oatmeal Creme Pies were some of my favorite cookies growing up and I could eat a box in a day. But these iced oatmeal bars are even better. In doing research for this recipe, I bought a box of Oatmeal Creme Pies. It had been nearly 20 years since I last tried them and unfortunately what I bit into didn’t match my beloved memories. I made it my mission to create a new oatmeal creme cookie recipe that’s worth biting into and I think is better than the original. I have so many oatmeal cookie recipes because when oatmeal cookies are done right — and by that I mean soft, chewy, and not over-baked — they’re some of my favorites. The chewiness, the perfectly hearty texture, and the nuttiness of the oats speak to me. Rather than go to the fussiness of making sandwich cookies to recreate the classic Little Debbie cookies, I made bars. Bars are so much faster and easier than cookies since there’s no dough to chill and nothing individual to roll. The bars are soft, very chewy from the oats, not at all cakey, and perfectly dense. It’s one-bowl, no-mixer batter and you’ll have it from the bowl and into the oven in less than five minutes with only one bowl to wash. Love that. The icing is buttercream frosting spiked with a jar of marshmallow creme and makes the bars taste truly authentic. It’s sweet, decadent, soft, fluffy, sticky, rich, and you’ll want to eat it by the spoonful.

How to Make Iced Oatmeal Cookie Bars
Making oatmeal bar cookies is even easier than making regular cookies because there’s no dough to chill or roll into balls. Win! Here’s an overview of how the cookie bars are made:
Can This Recipe Be Doubled?
Yes! Double the ingredients and bake the oatmeal cookie bars in a 9×13-inch pan.
Can This Recipe Be Made in Advance?
Yes! You can prepare the entire recipe as written a day before serving, or you can store the bars on your counter and pop the icing in the fridge until you’re ready to ice and serve.
Tips for Making Iced Oatmeal Bars
Use quick-cook oats rather than old-fashioned for the perfect amount of chewiness. You’re welcome to add more cinnamon to the bars if you’d like a more pronounced cinnamon flavor. You can halve the frosting portion if you’re not a huge frosting person, but I am. The more, the merrier!
