Step‑by‑Step Instructions for Iced Oatmeal Cookie Bars

Step 1: Prep Oats
Begin by pulsing the old-fashioned oats in a food processor until they are coarsely chopped, resembling a slightly chunky flour. This will enhance the chewiness of your Iced Oatmeal Cookie Bars. Once done, set them aside as you move on to the next step.

Step 2: Mix Wet Ingredients
In a large mixing bowl, combine the melted unsalted butter and both sugars, whisking vigorously for about one minute until the mixture is smooth and creamy. Add in the egg, vanilla extract, and molasses, mixing until everything is well incorporated. This will create a rich base for your bars.

Step 3: Combine Dry Ingredients
Next, fold in the coarsely chopped oats along with the all-purpose flour and any additional dry ingredients. Gently stir the mixture until just combined, being careful not to overmix, as this will keep your Iced Oatmeal Cookie Bars moist and chewy.

Step 4: Bake
Transfer your thick, oatmeal batter to a lined 8×8-inch baking pan and spread evenly. Preheat your oven to 350°F (175°C) and bake the bars for 20-24 minutes. They are done when the edges are set and lightly golden, while the center appears slightly soft, signaling a chewy texture.

Step 5: Cool & Glaze
Once baked, allow the bars to cool completely in the pan to achieve the best texture. After cooling, prepare your vanilla glaze and generously drizzle it over the bars. Allow the glaze to set before slicing them into squares for serving, ensuring a delightful sweet finish to your Iced Oatmeal Cookie Bars.

Iced Oatmeal Cookie Bars Recipe FAQs

How do I choose the best oats for this recipe?
Absolutely! Using old-fashioned oats provides the best texture and chewiness for your Iced Oatmeal Cookie Bars. If you use instant oats, the bars may turn out softer and less textured. Stick with old-fashioned oats for that delightful, classic oatmeal feel!

What is the best way to store leftover cookie bars?
You can store your Iced Oatmeal Cookie Bars in an airtight container at room temperature for up to 4 days. If you prefer a chilled dessert, they’ll stay fresh for about a week in the fridge, but let them come to room temperature for the best flavor.

What if I overbake the bars?
Oh no! If you accidentally overbake your Iced Oatmeal Cookie Bars, they might turn out a bit dry instead of chewy. Ensure you bake them until the edges are set and lightly golden while keeping the center slightly soft. If they seem too firm, try serving them with a scoop of your favorite ice cream—it’s a delicious remedy!

Are there any dietary considerations for pets or allergies?
Yes, indeed! While these bars are a tasty treat for humans, they contain ingredients like butter and eggs that aren’t suitable for pets, particularly dogs. As for allergens, keep in mind that they contain gluten from all-purpose flour and may pose a risk to those with wheat allergies. Always double-check labels and consider alternative flours if needed.
