Why You Will Love this Recipe

The cultural origins of oatmeal cookies date back to the 19th century when oats were introduced to American cuisine. From their humble beginnings, they have evolved into various forms, including the famous Crumbl-style iced version that we’re making today. The beauty of these cookies lies not just in their taste but also in their heartiness. The oats provide a wholesome quality, making them feel slightly more indulgent yet comforting.

These cookies fit right into any season—whether you’re making them for a summer picnic or a cozy winter evening. You might even find yourself baking a batch to share during the holidays! For me, they always remind me of my childhood, gathering around the table for family celebrations, sharing stories, and, of course, cookies!

As you prepare to make these ultimate iced oatmeal cookies, know that the recipe allows for plenty of room for creativity. Whether you want to add raisins, chocolate chips, or a hint of nutmeg, the possibilities are endless!

Ingredient Discussion

Let’s dive into the ingredients that make these ultimate iced oatmeal cookies so delicious:

Oats: Use rolled oats for a chewy texture. When selecting oats, look for the label that says “old-fashioned” as they hold their shape better than quick oats. If gluten is a concern, gluten-free oats are readily available.
All-purpose flour: This is your base for the cookie dough. You can substitute it with whole wheat flour for a nuttier flavor, but keep in mind it may change the texture slightly.
Brown sugar: This adds moisture and a rich caramel flavor. Dark brown sugar contains more molasses, giving a deeper flavor, while light brown sugar is milder.
Butter: Use unsalted butter for better control of the saltiness. Room temperature butter is essential for creating a smooth cookie dough.
Cinnamon: This spice is a must for that warm, comforting flavor. If you’re feeling adventurous, try adding nutmeg or pumpkin spice for a seasonal twist.
Egg: This binds the ingredients together, providing structure. For an egg-free version, you can use a flaxseed meal substitute.
Powdered sugar: Essential for the icing, it dissolves easily to create that smooth, sweet topping.
Milk: This thins the icing. Use whole milk for creaminess or almond milk for a dairy-free option.

When shopping for these ingredients, consider local or organic options for a fresher taste. Oats, in particular, can often be found in bulk sections, allowing you to choose only what you need. And if you have some seasonal variations, don’t hesitate to incorporate dried fruits or nuts! Trust me; it’ll add a delightful crunch to your cookies.

Equipment Needed

Before we get started, let’s gather the necessary tools:

Mixing bowls (large and medium)
Whisk and spatula
Baking sheet or cookie sheet
Parchment paper (for easy cleanup)
Cookie scoop or tablespoon (for uniform cookie sizes)
Cooling rack
Measuring cups and spoons
Electric mixer (optional but helpful for creaming butter and sugar)

Don’t worry if you don’t have a cookie scoop; you can always use a tablespoon to drop the dough onto the baking sheet. Just try to keep the sizes consistent for even baking!

Preparation Method

Now, let’s make those delicious cookies! Follow these simple steps:

Preheat your oven to 350°F (175°C). Line your baking sheet with parchment paper.
In a large mixing bowl, cream together 1 cup (227g) of unsalted butter and 1 cup (200g) of brown sugar. Beat until light and fluffy—about 3-5 minutes.
Add in 1 large egg and 1 teaspoon of vanilla extract, mixing until well combined.
In a separate bowl, whisk together 1 ½ cups (180g) of rolled oats, 1 cup (120g) of all-purpose flour, 1 teaspoon of baking soda, 1 teaspoon of cinnamon, and a pinch of salt.
Gradually add the dry mixture to the wet mixture, stirring until just combined. Be careful not to overmix, as this can lead to tough cookies.
Using a cookie scoop, drop rounded tablespoons of dough onto the prepared baking sheet, spacing them about 2 inches apart.
Bake for 10-12 minutes or until the edges are golden brown. The centers might look slightly underbaked, but they’ll firm up as they cool.
Remove from the oven and allow to cool on the baking sheet for 5 minutes before transferring to a cooling rack.
While the cookies are cooling, prepare the icing by whisking together 1 cup (120g) of powdered sugar and 2-3 tablespoons of milk until smooth. Adjust the consistency as needed.
Once the cookies are completely cool, drizzle the icing over each one. Let them sit for a few minutes to allow the icing to set.

Don’t forget to trust your senses! The smell of baking cookies is one of the best parts, and they should be golden on the edges with a slightly soft center when they come out!

Cooking Tips & Techniques

Here are some pro tips to ensure your iced oatmeal cookies turn out perfect:

Room Temperature Ingredients: Make sure your butter and egg are at room temperature. This helps create a smooth batter and ensures even baking.
Don’t Overmix: Mix just until combined to keep your cookies soft and chewy. Overmixing can develop gluten and lead to dense cookies.
Chill the Dough: If you have time, chill your cookie dough for 30 minutes before baking. This helps the flavors meld and can prevent spreading.
Watch the Baking Time: Ovens can vary, so keep an eye on your cookies. They should be golden but not overbaked. Remember, they’ll continue to firm up after you take them out!
Experiment with Icing: Feel free to add a splash of vanilla or almond extract to your icing for an extra flavor boost. You can even tint the icing with food coloring for special occasions!

Every baker has their mishaps; I once forgot to add the sugar and ended up with a bland cookie. Learn from those moments! Timing and multitasking in the kitchen can make all the difference.

Variations & Adaptations

If you want to mix things up with your iced oatmeal cookies, here are some fun variations:

Chocolate Chip Oatmeal Cookies: Fold in 1 cup (170g) of chocolate chips for a delightful twist.
Raisin Oatmeal Cookies: Add 1 cup (150g) of raisins for a classic take on this recipe.
Nutty Oatmeal Cookies: Toss in ½ cup (60g) of chopped nuts such as walnuts or pecans for extra crunch.

For those who prefer a different baking method, you can also make these cookies in a skillet! Just press the cookie dough into a greased skillet and bake until golden, then slice it into wedges for a fun sharing dessert.

Serving & Storage Suggestions

These cookies are best enjoyed fresh but can be stored for later! Here’s how:

Serving: Serve these cookies at room temperature for the best flavor. They pair wonderfully with a glass of milk or a cup of coffee!
Storage: Store the cookies in an airtight container at room temperature for up to a week. If you want to keep them longer, you can freeze them for up to three months.
Reheating: To enjoy a warm cookie, pop it in the microwave for about 10-15 seconds.

As the flavors meld, you might find that these cookies taste even better the next day! It’s like the icing and the oats have a chance to really get to know each other.
