Let’s dive into how you can make these amazing iced oatmeal cookie bars right at home. They remind me of those Mother’s Iced Oatmeal Cookies that stores used to sell!

The Perfect Cookie Bar Base with a Glaze on Top:

Before we talk about the icing (because who doesn’t love a good glaze?), let’s focus on the star of the show: the cookie bars themselves. This recipe strikes a balance between chewy, slightly crispy, and perfectly spiced with cinnamon. What’s an iced oatmeal cookie without the icing? The glaze on these cookie bars adds that sweet finishing touch that complements the hearty oats and warm spices perfectly. It’s a simple mixture, but it transforms these bars into something extra special.

What ingredients you need to make these iced oatmeal cookie bars:

• Egg – Eggs provide structure and moisture, helping the cookie bars achieve the perfect texture.
• Coconut oil, solidified – Coconut oil is a great alternative to butter for those seeking a dairy-free option. Solidified coconut oil gives these bars a rich flavor and keeps them moist. You can, of course, use butter if you prefer a more traditional taste.
• Coconut sugar – A healthier alternative to refined white sugar, coconut sugar adds a deeper caramel-like sweetness. Plus, it’s lower on the glycemic index, making it a great option for those looking to reduce their sugar intake.
• Molasses – Molasses is what gives oatmeal cookies that rich, classic flavor. It deepens the sweetness without being overpowering.
• Vanilla extract – Vanilla enhances the overall flavor of the bars, giving them a sweet, aromatic base.
• Gluten-free rolled oats – Oats are the heart of this recipe. They give the cookie bars a chewy texture and a wholesome flavor that makes them satisfying without being too heavy.
• Gluten-free oat flour – Oat flour keeps these cookie bars gluten-free while maintaining that lovely oat flavor. It also helps bind the ingredients together.
• Tapioca flour or arrowroot flour – Tapioca or arrowroot flour acts as a binding agent, helping the bars hold their shape while still being soft and tender.
• Cinnamon – Cinnamon is the perfect spice to elevate the flavor of oatmeal. Its warmth adds depth to the sweetness of the coconut sugar and molasses.
• Powdered sugar: Powdered sugar is ideal for glazes because it dissolves easily and creates a smooth, sweet icing.
• Non-dairy milk: You can use any non-dairy milk (like almond, oat, or coconut milk). Add more if you need a thinner consistency.

Method: How to Create Your Cookie Bars:

1. Preheat your oven: Start by preheating your oven to 350°F (175°C). This ensures an even bake for your cookie bars.

2. Cream the wet ingredients: In a large bowl, beat the egg, coconut oil, coconut sugar, molasses, and vanilla extract until well-combined. If you’re using butter instead of coconut oil, make sure it’s softened to room temperature so it mixes easily with the other ingredients.

3. Mix the dry ingredients: In another bowl, whisk together the gluten-free rolled oats, oat flour, tapioca flour, baking powder, baking soda, and cinnamon. Make sure everything is well-combined to ensure even distribution of the leavening agents.

4. Combine wet and dry ingredients: Slowly add the dry ingredients to the wet ingredients, mixing until a soft dough forms. The dough should be sticky but manageable.

5. Press into a pan: Line an 8×8-inch baking pan with parchment paper, leaving some overhang for easy removal later. Press the dough evenly into the pan, smoothing the top with the back of a spoon or a spatula.

6. Bake: Bake the cookie bars for about 15 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out clean. Be careful not to overbake, as you want the bars to remain soft and chewy.

7. Cool completely: Once the bars are out of the oven, let them cool in the pan for 10 minutes before transferring them to a wire rack to cool completely. This will ensure that the bars hold their shape when cut.

8. Make the glaze: whisk the ingredients in a small bowl, whisk together the powdered sugar, non-dairy milk, and vanilla extract until smooth. If the mixture is too thick, add a little more milk, a teaspoon at a time, until you reach your desired consistency.

9. Drizzle or spread: Once the cookie bars are completely cooled, drizzle the glaze over the top using a spoon or a piping bag. If you prefer, you can spread it with a spatula for an even coating.

10. Let it set: Allow the glaze to set for about 10-15 minutes before slicing and serving the bars. This will give the icing time to harden slightly, making the bars easier to cut and serve.

Why You’ll Love These Iced Oatmeal Cookie Bars:

1. Gluten-free: These bars are made with gluten-free oats and oat flour, making them a great option for anyone with gluten sensitivities or those looking to avoid gluten.

2. Dairy-free option: Using coconut oil and non-dairy milk ensures that these bars are suitable for those who are lactose intolerant or avoiding dairy. If you prefer, you can easily substitute butter and regular milk if dairy isn’t an issue.

3. Healthier sugar alternatives: With coconut sugar and molasses, these bars have a more natural sweetness compared to traditional refined sugar recipes. While still indulgent, the use of better-for-you ingredients means you can feel a little better about enjoying one (or two!).
