How to Make Iced Oatmeal Cookie Bars

Making Iced Oatmeal Cookie Bars is a simple step-by-step process. By following the directions closely, you can create a perfect batch every time. Let’s get started!

Ingredients:

1 cup old-fashioned oats
1 cup all-purpose flour
1/2 cup brown sugar
1/2 cup granulated sugar
1/2 cup unsalted butter, softened
1 large egg
1 teaspoon baking soda
1/2 teaspoon cinnamon
1/2 teaspoon salt
1 teaspoon vanilla extract
1 cup powdered sugar
1-2 tablespoons milk (for glaze)
1/2 teaspoon vanilla extract (for glaze)

Directions:

Preheat the Oven: Preheat your oven to 350°F (175°C). This step is important because it ensures that your bars bake evenly.
Prepare the Pan: Grease a 9×9 inch baking pan with butter or non-stick spray. This will prevent the bars from sticking to the pan.
Cream Butter and Sugars: In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until the mixture is smooth and fluffy. This process incorporates air into the mixture, making your bars light.
Add Egg and Vanilla: Beat in a large egg and 1 teaspoon of vanilla extract. Mix until well combined. The egg adds moisture and helps bind the ingredients together.
Combine Dry Ingredients: In another bowl, combine 1 cup of old-fashioned oats, 1 cup of all-purpose flour, 1 teaspoon of baking soda, 1/2 teaspoon of cinnamon, and 1/2 teaspoon of salt. Stir these dry ingredients together until they are fully mixed.
Mix Wet and Dry: Gradually add the dry mixture to the wet mixture, stirring gently until just combined. Be careful not to overmix, as this can make the bars tough.
Spread in Pan: Spread the batter evenly into the prepared baking pan, ensuring it reaches all corners.
Bake: Bake in the preheated oven for 20-25 minutes, or until the top is golden brown. To check if they are done, you can insert a toothpick into the center. If it comes out clean, your bars are ready.
Cool: Allow the baked bars to cool in the pan for a few minutes, then transfer them to a wire rack to cool completely.
Make the Glaze: In a small bowl, mix together 1 cup of powdered sugar, 1-2 tablespoons of milk, and 1/2 teaspoon of vanilla extract until smooth. Adjust the milk to achieve your desired consistency for the glaze.
Glaze the Bars: Once the bars are fully cool, drizzle the prepared glaze over the top, allowing it to seep into the bars for added sweetness.
Cut and Serve: Cut the bars into squares. Enjoy them as a delightful snack or dessert!

How to Serve Iced Oatmeal Cookie Bars

These cookie bars can be served warm or at room temperature. When serving, you can provide them plain or add extra toppings such as chopped nuts, chocolate chips, or even a dusting of cinnamon. They pair wonderfully with a glass of milk or a cup of coffee, making them perfect for afternoon tea or a casual gathering with friends.

How to Store Iced Oatmeal Cookie Bars

To store your Iced Oatmeal Cookie Bars, wait until they are completely cooled down. Then, you can place them in an airtight container. Keep them at room temperature for up to 3-4 days. If you want to keep them for a longer time, you can refrigerate them, which will extend their freshness for about a week. For longer storage, consider freezing the bars. Wrap them tightly in plastic wrap or aluminum foil and then place them in a freezer-safe bag. They can be frozen for up to 2-3 months. Just thaw them at room temperature before serving.

Tips to Make Iced Oatmeal Cookie Bars

Use Rolled Oats: Stick to old-fashioned rolled oats for the best texture. Instant oats may make the bars too mushy.
Don’t Overmix: When combining wet and dry ingredients, mix just until combined to maintain the lightness of your bars.
Check for Doneness: Ovens can vary, so check the bars a few minutes before the end of the baking time.
Customize the Glaze: You can add spices like nutmeg or even lemon zest to the glaze for a different flavor profile.
Add Texture: Consider adding chopped nuts, chocolate chips, or dried fruit to the batter for added flavor and texture.

Variation

If you’re looking to switch things up, there are several variations you can try with these cookie bars:

Add Chocolate Chips: Incorporate 1 cup of chocolate chips into the batter for a delicious chocolatey twist.
Nutty Flavor: Add chopped walnuts or pecans into the mixture for some crunch.
Spiced Up: Change the cinnamon to pumpkin pie spice or add a touch of cloves for a festive flavor.
Fruits: Fold in some raisins or cranberries for added sweetness and chewiness.

FAQs

1. Can I use quick oats instead of old-fashioned oats for this recipe?

It’s best to use old-fashioned oats for this recipe. Quick oats may yield a different texture and won’t hold up as well in baking.

2. Can I make the glaze ahead of time?

Yes, you can prepare the glaze ahead of time. Store it in an airtight container in the refrigerator, and give it a good stir before using it.

3. How can I tell when the bars are done baking?

The bars are done when they are golden brown on top and a toothpick inserted in the center comes out clean. Keep an eye on them as baking times might vary depending on your oven.

4. Can I substitute the butter with oil?

Although it’s possible to use oil, it may change the flavor and texture. If you choose to use oil, use a light-flavored oil like canola and keep an eye on the moisture content.

5. Are these bars good for freezing?

Yes, these bars freeze very well. Wrap them tightly and place them in a freezer-safe container. Thaw in the refrigerator before enjoying.

Iced Oatmeal Cookie Bars are an easy and delicious treat that is sure to please everyone. Whether you’re baking for a special occasion or just a simple family snack, these bars offer a delightful blend of flavors and textures. Enjoy!
