Step‑by‑Step Instructions for Oatmeal Raisin Cookie Bars
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it warms up, prepare a 9×9-inch baking pan by greasing it lightly and lining it with parchment paper, leaving some overhang for easy removal later. This step sets the stage for baking your delicious Oatmeal Raisin Cookie Bars to perfection.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, baking soda, ground cinnamon, and salt until well combined. This blend of ingredients will provide the structure and flavor needed for your cookie bars. As you mix, take in the warm spice aroma and feel the anticipation build for the wholesome treat about to come.
Step 3: Cream Butter and Sugar
In a large mixing bowl, beat the unsalted butter and brown sugar together using an electric mixer on medium speed for about 2–3 minutes. You’ll want the mixture to become light and fluffy. Once achieved, add the eggs one at a time, incorporating each egg fully before adding the next. Lastly, stir in the vanilla extract for a delightful boost of flavor.
Step 4: Combine Wet and Dry Ingredients
Gradually mix the dry ingredient blend into the wet ingredients using a spatula, folding until just combined. You’ll notice the dough becomes thicker as you blend, which is exactly what you want for those scrumptious Oatmeal Raisin Cookie Bars. Avoid overmixing; a few small lumps are perfectly fine!
Step 5: Add Oats and Raisins
Gently fold in the old-fashioned oats and raisins until they are evenly distributed throughout the dough. The mixture will be thick, so use a sturdy spatula to ensure everything is well combined. This step is where the heartiness of the oats and the sweetness of the raisins shine through.
Step 6: Bake the Bars
Carefully spread the dough into your prepared baking pan, pressing it down evenly. If desired, sprinkle a few extra raisins on top for added visual appeal. Bake in your preheated oven for 18–20 minutes, or until the edges turn golden brown. You can check for doneness with a toothpick; it should come out clean or with just a few moist crumbs.
Step 7: Cool the Bars
Once baked, allow your Oatmeal Raisin Cookie Bars to cool in the pan for about 5–10 minutes. This resting period helps them firm up a bit before transferring. After that, use the parchment overhang to lift the bars out of the pan and cool completely on a wire rack, which is essential before frosting.
Step 8: Make the Frosting
While the bars cool, prepare the luscious maple-cinnamon frosting. Beat the softened butter in a mixing bowl until smooth. Gradually add the powdered sugar, followed by the maple syrup, heavy cream, and ground cinnamon. Mix until you reach a creamy consistency—this frosting will elevate your Oatmeal Raisin Cookie Bars to a divine level.
Step 9: Frost and Serve
Once the cookie bars are completely cool, spread the creamy maple-cinnamon frosting generously on top. Cut the bars into squares, and get ready to serve this delightful treat to family and friends. Relish in the warmth and comfort of your homemade Oatmeal Raisin Cookie Bars with a cup of tea or coffee.

Expert Tips for Oatmeal Raisin Cookie Bars
-
Soften Butter: Ensure your unsalted butter is at room temperature for easy blending. Cold butter can lead to a dense texture that doesn’t rise well.
-
Check for Doneness: Use a toothpick to test if the bars are done baking. It should come out clean or with just a few moist crumbs for the perfect chewy texture.
-
Cool Completely: Allow the bars to cool completely before frosting. This will prevent the frosting from melting into a gooey mess and keep the layers distinct.
-
Watch for Overmixing: When combining wet and dry ingredients, be careful not to overmix. Overworking the dough can lead to tougher cookie bars, rather than the desired chewy consistency.
-
Extra Treats: For added flavor and texture, sprinkle a few extra oats or raisins on top of the dough before baking. It enhances the visual appeal and adds more delightful bites!

Oatmeal Raisin Cookie Bars Recipe FAQs
How do I select the best oats for this recipe?
Absolutely! For the best texture, I recommend using old-fashioned oats, as they provide the perfect chewiness. If you don’t have those on hand, you can opt for rolled oats, which work well too. Just avoid instant oats, as they can lead to a mushy texture in your cookie bars.
How should I store my Oatmeal Raisin Cookie Bars?
You can store your cookie bars in an airtight container at room temperature for up to 1 week. This will keep them soft and chewy. For longer freshness, refrigerate them, which can extend their life to about 2 weeks. Just make sure to let them come to room temperature before you dig in!
Can I freeze the cookie bars?
Yes, you can absolutely freeze your Oatmeal Raisin Cookie Bars! To do this, wrap individual bars tightly in plastic wrap and then place them in a freezer-safe bag. They can be stored in the freezer for up to 3 months. When you’re ready to enjoy them, simply thaw overnight in the fridge or at room temperature for a couple of hours. For a warm treat, you can microwave them for 10-15 seconds!
What’s the best way to prevent my bars from becoming too dry?
To keep your cookie bars nice and moist, make sure not to overbake them. Check for doneness around the 18-minute mark—they should be golden and a toothpick should come out clean or with a few moist crumbs. Also, allow them to cool completely in the pan before frosting; this keeps them from drying out and ensures they maintain that lovely chewy texture.
Are there any dietary considerations I should be aware of?
Definitely! If you’re making these cookie bars for a crowd, consider potential allergies. They contain gluten from the all-purpose flour and dairy from the butter. For a vegan version, substitute flax eggs for the regular eggs and use margarine instead of butter. Always check the labels of your ingredients if you’re serving those with allergies!
Can I use other ingredients or variations?
Definitely! The great thing about these Oatmeal Raisin Cookie Bars is their versatility. You can swap out raisins for chocolate chips or dried cranberries for a different flavor twist. If you’re feeling adventurous, adding chopped walnuts or pecans will introduce a delightful nutty crunch. Enjoy experimenting!
