How to Make Oatmeal Raisin Cookie Bars
Preheat your oven to 350°F. Coat a 9×9 pan with baking spray, then line it with parchment paper. This will ensure your cookie bars come out easily.
Combine flour, baking soda, cinnamon, and salt in a bowl. Mix these dry ingredients until well blended, and set aside while you prepare the wet mixture.
Beat the butter and brown sugar in another bowl until light, fluffy, and smooth about 2 to 3 minutes. Scrape down the sides and bottom of the bowl as needed to ensure even mixing.
Add the eggs one at a time, mixing well after each addition. Don t forget to scrape the bowl every now and then for an even batter.
Incorporate the vanilla extract, which adds a delightful aroma and flavor to your cookie bars.
Gradually add the dry ingredients to the wet mixture, mixing until no streaks of flour remain. Use a rubber spatula to ensure the dough is thoroughly combined and well-mixed.
Fold in the oats and raisins gently; you ll notice the dough is thick and sticky. This is where the chewy goodness starts forming!
Press the dough evenly into the prepared pan, and feel free to sprinkle top with extra raisins if desired for a burst of sweetness.
Bake for 18 to 20 minutes, or until the edges start to look golden brown. Your kitchen will smell heavenly by this point!
Cool the cookie in the pan for 5 to 10 minutes. Then, lift it out using the parchment paper and let it cool completely on a wire rack.
Make the frosting by beating the butter in a bowl until it s smooth and lump-free.
Gradually add powdered sugar to the butter, mixing until completely combined and fluffy.
Stir in the maple syrup, heavy cream, cinnamon, and optional maple extract for that wonderful flavor boost.
Spread the frosting over the cooled cookie bars and cut them into squares. Serve and enjoy the sweetness of your creation!
Optional: Drizzle extra maple syrup on top for an added touch of sweetness.

Helpful Tricks for Oatmeal Raisin Cookie Bars
Use Room Temperature Ingredients: Ensure your butter and eggs are at room temperature for easy mixing and a smoother dough.
Don t Overmix: After adding the dry ingredients, mix just until combined. Overmixing can lead to tough, dense bars instead of tender, chewy ones.
Check for Doneness: Bake until the edges are golden and a toothpick inserted comes out with a few moist crumbs. This yields the perfect chewy texture of oatmeal raisin cookie bars.
Cool Completely: Let the cookie bars cool entirely before frosting to prevent melting the frosting and getting a messy finish.
Customize Toppings: Feel free to add extra raisins or even nuts for added texture. Play around with flavors to make these oatmeal raisin cookie bars feel unique!
