How to Make Oatmeal Sandwich Cookies with Maple Brown Sugar Buttercream
Prepare Your Oven and Baking Sheets: Preheat oven to 350°F (175°C). Line baking sheets with parchment paper; this prevents sticking and makes cleanup a breeze.
Mix Dry Ingredients Together: In a bowl, whisk together oats, flour, baking soda, cinnamon, and a pinch of salt until blended evenly.
Create the Cookie Dough Base: In another bowl, cream together softened butter, granulated sugar, and brown sugar until light and fluffy—about 3-4 minutes should do.
Add Eggs and Vanilla Extract: Beat in the eggs one at a time along with vanilla extract until fully incorporated; this enhances flavor and richness.
Combine Wet and Dry Ingredients: Gradually add your dry mixture to the wet ingredients while mixing on low speed until just combined; don’t overmix!
Scoop and Bake Cookies: Using a cookie scoop or spoon, drop dough onto prepared baking sheets about two inches apart. Bake for 10-12 minutes or until edges are golden but centers remain soft.
Make the Maple Brown Sugar Buttercream: While cookies cool down, beat softened butter with powdered sugar and maple syrup until smooth. Adjust sweetness by adding more powdered sugar if necessary.

This amazing oatmeal sandwich cookies with maple brown sugar buttercream recipe is a delightful treat that combines nostalgia and comfort. You’ll love the chewy texture paired with creamy frosting.
Three Key Tips:
Choose old-fashioned oats for better texture; they provide a heartier bite in every cookie. I always find that they remind me of my grandma’s kitchen, filled with warm cookies.
Chill the cookie dough for at least 30 minutes; it prevents spreading and enhances flavor. Trust me, I’ve made the mistake of skipping this step—no one wants flat cookies!
Use room temperature butter for an easy-to-work-with dough; it’s crucial for that light, fluffy buttercream. My first attempt was a melted mess, but now I’m a pro.
Perfecting the Cooking Process
Start by creaming your butter and sugars until fluffy, then gradually add in eggs and dry ingredients. Bake until golden brown, but watch them closely to avoid over-baking.
Add Your Touch
Feel free to mix in some chocolate chips or nuts for extra flavor and texture. A pinch of cinnamon can also elevate these cookies to new heights; it reminds me of cozy autumn evenings.
Storing & Reheating
Store the cooled cookies in an airtight container at room temperature for up to five days. If you want to reheat them, just pop them in the microwave for about 10 seconds—pure bliss!
