Ingredients You’ll Need

These iced oatmeal cookie bars require simple, wholesome ingredients that you probably already have in your pantry. Let’s gather what we need to create this delightful treat!

For the Cookie Bars

  • 1/2 cup (113 g) unsalted butter, melted and slightly cooled
  • 1 cup (95 g) old fashioned oats
  • 1 cup plus 2 tablespoons (140 g) all-purpose flour, spooned and leveled
  • 1 teaspoon baking soda
  • 1 teaspoon cinnamon
  • 1/2 teaspoon salt
  • 1/2 cup (100 g) granulated sugar
  • 1/2 cup (100 g) light brown sugar, packed
  • 1 large egg, room temperature
  • 1 teaspoon vanilla extract
  • 1 tablespoon molasses (or honey)

For the Icing

  • 1/2 cup (60 g) powdered sugar, sifted
  • 1 to 2 tablespoons whole milk
  • 1/4 teaspoon vanilla extract

Variations

This recipe is wonderfully flexible! Here are some fun variations to try out:

  • Add nuts: Toss in some chopped walnuts or pecans for added crunch and flavor.
  • Make it chocolatey: Swirl in some chocolate chips or cocoa powder for a rich twist on classic oatmeal cookies.
  • Go fruity: Add raisins or dried cranberries for a chewy burst of sweetness in every bite.
  • Healthier swap: Replace half the granulated sugar with applesauce or use coconut sugar for a lower glycemic index option.

How to Make Iced Oatmeal Cookie Bars Recipe

Step 1: Preheat Your Oven

Preheat your oven to 350°F. This step ensures that your cookie bars bake evenly. While the oven heats up, line an 8 x 8 inch baking pan with parchment paper—this will make removing the bars so much easier later!

Step 2: Prepare the Oats

Melt the butter and let it cool slightly in a medium bowl. Meanwhile, pulse the oats in a food processor until they are broken down but not turned into flour. This gives your cookie bars that lovely chewy texture.

Step 3: Mix Dry Ingredients

In another bowl, whisk together the pulsed oats, flour, baking soda, cinnamon, and salt. Mixing these dry ingredients ensures that everything is evenly distributed throughout your batter.

Step 4: Combine Wet Ingredients

To the melted butter, add both sugars and mix until it resembles wet sand. Then add the egg along with vanilla and molasses. Mixing well here helps incorporate air into your mixture—this means fluffier cookie bars!

Step 5: Blend It All Together

Gently fold the dry ingredients into your wet mixture using a spatula until just combined. Be careful not to overmix; this keeps your bars soft and chewy.

Step 6: Bake Your Bars

Transfer the dough into the prepared baking pan and spread it evenly. Bake for about 20 to 24 minutes until golden brown around the edges. Keep an eye on them as overbaking can lead to dry bars!

Step 7: Cool Down & Ice

Once baked, allow your bars to cool in the pan on a cooling rack for about 1-2 hours before icing them with sweet vanilla glaze. This cooling period is crucial—if they’re too warm when you add icing, it’ll melt away!

And there you have it! Enjoy every delicious bite of these iced oatmeal cookie bars—they’re sure to bring smiles all around!

Pro Tips for Making Iced Oatmeal Cookie Bars Recipe

To ensure your iced oatmeal cookie bars turn out perfectly every time, keep these handy tips in mind!

  • Use room temperature ingredients: Bringing your egg and any other refrigerated ingredients to room temperature helps them blend more easily into the batter, resulting in a smoother texture.

  • Don’t overmix the batter: Gently folding the dry ingredients into the wet ensures that your bars remain soft and chewy. Overmixing can lead to dense, tough bars.

  • Check for doneness with a toothpick: Insert a toothpick into the center of the bars; if it comes out mostly clean (with just a few moist crumbs), they’re ready to come out of the oven.

  • Cool completely before icing: Allowing your bars to cool completely ensures that the icing doesn’t melt off and instead creates a lovely glaze on top.

  • Store properly: Keep your iced oatmeal cookie bars in an airtight container at room temperature for up to a week, or refrigerate for longer freshness!

How to Serve Iced Oatmeal Cookie Bars Recipe

These delightful iced oatmeal cookie bars are not only perfect on their own but also shine when paired with complementary flavors and garnishes. Here’s how you can elevate your serving game!

Garnishes

  • Chopped nuts: A sprinkle of chopped walnuts or pecans adds crunch and enhances the flavor profile of your bars.
  • Cinnamon dusting: A light dusting of cinnamon on top of the icing gives an extra kick of warmth and spice.
  • Fresh fruit: Serve alongside fresh berries or sliced bananas to add a refreshing contrast to the sweetness.

Side Dishes

  • Vanilla ice cream: A scoop of vanilla ice cream beside your warm bars creates a delightful contrast in temperature and texture.
  • Fruit salad: A light fruit salad brings brightness and balances out the rich flavors of the cookie bars.
  • Coffee or tea: Pairing your dessert with a warm cup of coffee or herbal tea enhances the overall experience and makes it feel cozy.
  • Milk: A classic choice that complements sweet treats beautifully—serve chilled for dipping!

Make Ahead and Storage

These iced oatmeal cookie bars are perfect for meal prep, making them an excellent choice for busy weeks. You can easily make a batch ahead of time and enjoy them throughout the week!

Storing Leftovers

  • Allow the bars to cool completely before storing.
  • Place the iced oatmeal cookie bars in an airtight container.
  • Store at room temperature for up to 4 days or in the refrigerator for up to a week.

Freezing

  • Cut the cooled bars into squares before freezing for easy serving.
  • Wrap each square tightly in plastic wrap or aluminum foil.
  • Place wrapped bars in a freezer-safe bag or container and freeze for up to 3 months.

Reheating

  • To enjoy frozen bars, remove from the freezer and let them thaw in the refrigerator overnight.
  • For a warm treat, pop them in the microwave for about 10-15 seconds, just until warmed through.

FAQs

Can I make this Iced Oatmeal Cookie Bars Recipe gluten-free?

Yes! To make this recipe gluten-free, substitute all-purpose flour with a gluten-free flour blend. Ensure that your oats are certified gluten-free as well.

How long will the Iced Oatmeal Cookie Bars last?

When stored properly in an airtight container at room temperature, these iced oatmeal cookie bars will last up to 4 days. If refrigerated, they can stay fresh for up to a week.

Can I use quick oats instead of old fashioned oats?

While quick oats can be used, they may result in a different texture. Old fashioned oats provide more chewiness and support the structure of the bars better.

What can I substitute for molasses in this recipe?

If you don’t have molasses on hand, honey or maple syrup can be used as a substitute. However, note that this may slightly alter the flavor profile.

Final Thoughts

I hope you enjoy making these delightful iced oatmeal cookie bars! They are not only easy to whip up but also wonderfully satisfying and perfect for sharing with friends and family. Each bite is filled with warmth and nostalgia that will surely bring smiles all around. Happy baking!
