Ingredients

  • 1 cup all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon ground nutmeg
  • 1/2 cup unsalted butter, softened
  • 1 cup brown sugar, packed
  • 1/2 cup granulated sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 2 cups old-fashioned rolled oats
  • 1/2 cup raisins or chocolate chips, optional
  • 1 cup powdered sugar
  • 2 tablespoons milk
  • 1 teaspoon vanilla extract for frosting

Directions & Preparation

  1. Preheat your oven to 350°F (175°C) and line a 9×13 inch baking pan with parchment paper, leaving some overhang for easy removal.
  2. In a medium bowl, whisk together the flour, baking soda, salt, cinnamon, and nutmeg. Set aside.
  3. In a large mixing bowl, cream the softened butter, brown sugar, and granulated sugar until light and fluffy, about 2-3 minutes.
  4. Add the egg and vanilla extract to the butter mixture, mixing well until combined.
  5. Gradually add the dry ingredients to the wet mixture, stirring until just incorporated. Fold in the rolled oats and add raisins or chocolate chips if desired.
  6. Spread the batter evenly into the prepared baking pan, smoothing the top with a spatula.
  7. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Allow to cool in the pan on a wire rack.
  8. Once cooled, make the frosting by whisking together powdered sugar, milk, and vanilla extract until smooth and pourable.
  9. Spread the frosting over the cooled oatmeal cookie bars, then cut into squares for serving.

FAQs

What can I do if my icing is too thick?

Add a little more milk, one teaspoon at a time, to reach your desired consistency.

How do I know when my bars are done baking?

The bars are done when the edges are lightly golden and a toothpick inserted in the center comes out clean.

Can I use quick oats instead of rolled oats?

Yes, but the texture will differ; quick oats create a finer texture in the bars.

What if my cookie bars are too crumbly?

This can happen due to overbaking or not enough moisture; ensure precise measurements and bake just until set.

Can I add nuts to the recipe?

Absolutely! Chopped walnuts or pecans complement the flavors well.

How can I adjust the sweetness of the frosting?

Reduce the powdered sugar for less sweetness or add a touch more for a sweeter glaze.

Conclusion

These iced oatmeal cookie bars promise a satisfaction that goes beyond their comforting flavors. They are a simple, yet elegant treat that can bring joy to any occasion.

With just a few basic ingredients, you can create a delightful dessert that is sure to please family and friends alike. Enjoy these bars with a cup of coffee or as a sweet ending to any meal.
