Bars, Blondies & Brownies/ Cookies

Oatmeal Cookie Bars with Maple Cinnamon Icing

Another easy cookie bar recipe for you!  I looooooove me some oatmeal cookies and another one of my other favorite lieutenants at work mentioned she had heard I make the BEST Oatmeal Raisin Cookies.  Hint, hint 😉  I asked Lt. if she would like me to make her some oatmeal cookies (yes…duh!), but told her I would have to make a different variety oatmeal cookie from the Oatmeal Raisin Cookies I had already made.  You know…new blog post!  Hahaha.  I gave Lt. some oatmeal cookie options, but she pretty much said everything I mentioned sounded good.  So what I came up with was a yummy oatmeal cookie bar topped with a maple cinnamon icing!  And I declare these are cookies perfect for breakfast, snack or dessert!

Oatmeal cookies!  My favorite all time cookie!!  But since I already have THESE and THESE oatmeal cookies on the blog, I decided to make oatmeal cookies in bar form, and then top them with icing.  My obsession with bar cookies continues y’all!  But this recipe is totally different from any of my previous oatmeal cookie recipes on the blog.  But I beg you….please, please, please don’t skip the icing…it is so easy to mix up!  And that maple……mmmmmmmm.  I bought my maple extract (maple flavoring) from Target.

The batter mixes up quickly and then you just dump the batter in your pan and BAKE!

Oatmeal Cookie Bars with Maple Cinnamon Icing

Print Recipe
Serves: 30 Cooking Time: 25-30 minutes


  • 1 cup unsalted butter, room temperature
  • 1/2 cup light brown sugar, packed
  • 1/2 cup dark brown sugar, packed (you can use light brown sugar if that is all you have)
  • 1/2 cup white granulated sugar
  • 1 tablespoon light corn syrup (optional--adds an extra softness to the cookies)
  • 2 eggs, room temperature
  • 2-1/2 teaspoons vanilla extract (I used VAIN Mexican Vanilla Extracted in Cane Rum)
  • 1/4 teaspoon salt
  • 1-1/2 cups all-purpose flour
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1 teaspoon baking soda
  • 1 teaspoon baking powder
  • 1 cup quick cooking oats
  • 1 cup old fashioned oats
  • 2 cups powdered sugar
  • 1 tablespoon maple extract
  • 1/2 teaspoon ground cinnamon
  • 2-3 tablespoons water





Preheat oven to 350-degrees. Line a 9x13-inch baking pan with foil or parchment paper and spray the bottom and sides with baking spray. Set aside.


In the bowl of a stand mixer, affixed with the paddle attachment, add the butter and beat on medium-high speed until light and creamy. Add the light brown sugar, dark brown sugar, white sugar and corn syrup to the butter and beat until light and fluffy. Scrape down the sides of the mixing bowl as needed. Add the eggs to the butter-sugar mixer, one at a time, beating one egg into the mixture completely before adding the second egg. Add the vanilla extract and salt to the mixer, mixing until combined.


Change the mixer speed to low and slowly add the flour, cinnamon, nutmeg, baking soda, baking powder and both oats to the mixer. Mix on low until just combined. Pour dough batter out into prepared pan and spread the batter evenly in the pan. Bake in 350-degree oven for 25-30 minutes or until a toothpick inserted in the middle comes out without raw batter on it. Do not over bake, as the bars will continue to bake in the pan once they are removed from the oven.


Remove baked cookie bars from the oven and let set on the counter to cool. While bars are cooling, prepare the maple cinnamon icing.




In a small bowl, add the powdered sugar, maple extract, ground cinnamon and water. Stir the mixture until combined and smooth. If icing is too runny, add more sugar a tablespoon at a time, until desired consistency is reached. If icing is too dry, add water by the teaspoon, until desired consistency is reached.


Remove the cookie bars from the pan, by lifting the bars from the pan using the excess parchment paper on the sides. Place bars on a wire rack, still on the parchment paper, and pour the prepared icing over the cooled oatmeal cookie bars. Allow the icing to drip off the sides of the bars. Once the icing has cooled and set, cut into desired sized squares.


Store in an airtight container, at room temperature. Bars stay fresh for several days.

This maple icing smells like a maple donut!!!!

Mmmm….thick oatmeal cookie bars.  With icing.  Perfect with coffee or tea!

That thin layer of icing is perfection!!

So what do you think??  Are these okay to eat for breakfast?!  Oatmeal and maple are TOTALLY breakfast…duh!  Hahaha.  Lt. shared these with the guys on Second Platoon and everyone loved them!  I mean you know people loved them, when they go out of their way a week later to tell you how amazing they were!

    that thing where you asked her if she wanted cookies and then told her they had to be from a new recipe is so me 😂 at least she was game for anything! i used to leave out some details and make my brother new things because i wanted to try them out, but he’s a little bit pickier (aka avocado mac and cheese wasn’t up his alley).

    I always tell people they have to chose something new too–why make something old when you can invent something new!
