  • Refrigerated
    • 1 Egg
  • Condiments
    • 1 tbsp Corn syrup, dark
  • Pasta & Grains
    • 1 1/4 cups Quick oats
  • Baking & Spices
    • 1 cup All-purpose flour
    • 1/8 tsp Allspice, ground
    • 1/4 tsp Baking powder
    • 1/2 tsp Baking soda
    • 1 cup Brown sugar, firmly packed dark
    • 3/4 tsp Cinnamon, ground
    • 1/8 tsp Cloves, ground
    • 1/2 tsp Nutmeg, ground
    • 3/4 tsp Salt
    • 2 tsp Vanilla extract


  1. Prepare the Brown Butter: In a small saucepan, melt the butter over medium heat, stirring frequently. Continue to cook the butter until it turns a deep golden brown color and develops a nutty aroma, about 5-7 minutes. Be careful not to let the butter burn. Remove from heat and allow it to cool slightly.
  2. Mix the Dry Ingredients: In a large mixing bowl, whisk together the all-purpose flour, quick oats, baking powder, baking soda, salt, cinnamon, cloves, nutmeg, and allspice until well combined. Set aside.
  3. Combine the Wet Ingredients: In another bowl, whisk together the brown sugar, cooled brown butter, egg, corn syrup, and vanilla extract until smooth and creamy.
  4. Combine the Wet and Dry Ingredients: Pour the wet ingredients into the bowl of dry ingredients and mix until a thick, sticky dough forms. If the dough is too wet, add a bit more flour. If it’s too dry, add a splash of milk.
  5. Chill the Dough: Cover the dough with plastic wrap and refrigerate for at least 1 hour, or until firm.
  6. Preheat the Oven: Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
  7. Shape the Cookies: Using a tablespoon or cookie scoop, portion out the dough and roll it into balls. Place the dough balls onto the prepared baking sheet, leaving some space between each cookie.
  8. Bake the Cookies: Transfer the baking sheet to the preheated oven and bake the cookies for 10-12 minutes, or until lightly golden brown around the edges. Remove from the oven and let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
  9. Prepare the Filling: While the cookies are cooling, prepare the filling by combining softened butter, powdered sugar, and vanilla extract in a mixing bowl. Beat until smooth and creamy.
  10. Assemble the Sandwich Cookies: Once the cookies have cooled completely, spread a generous dollop of the filling onto the bottom of one cookie, then sandwich it with another cookie, pressing down gently to adhere. Repeat with the remaining cookies and filling.
  11. Serve and Enjoy: Serve these irresistible Brown Butter Oatmeal Sandwich Cookies with a tall glass of cold milk or your favorite hot beverage for the ultimate indulgence. Enjoy the delightful combination of flavors and textures with every blissful bite.

Cook Notes and Variations:

  • Enhance the Nuttiness: For an extra boost of nutty flavor, toast the oats in a dry skillet over medium heat for a few minutes until fragrant before incorporating them into the dough.
  • Experiment with Fillings: Get creative with the filling by adding a hint of citrus zest, such as orange or lemon, for a refreshing twist. Alternatively, incorporate chopped nuts or chocolate chips for added texture and indulgence.
  • Customize the Spices: Adjust the spices according to your taste preferences. Increase the amount of cinnamon for a more pronounced cinnamon flavor, or omit the cloves if you prefer a milder spice profile.
  • Dress Them Up: For a festive touch, roll the edges of the assembled cookies in chopped nuts, sprinkles, or shredded coconut before serving. This adds a decorative flair and extra crunch to the cookies.

Keto and Low-Carb Versions:

  • Keto-Friendly Option: To make keto-friendly Brown Butter Oatmeal Sandwich Cookies, substitute almond flour for the all-purpose flour and use a low-carb sweetener such as erythritol or stevia instead of brown sugar and corn syrup. Opt for a keto-friendly filling using cream cheese, powdered erythritol, and vanilla extract.
  • Low-Carb Twist: For a lower-carb version, reduce the amount of flour and oats used in the recipe and increase the proportion of almond flour or coconut flour. Use a sugar-free sweetener and a low-carb syrup alternative to keep the carb count minimal while still achieving the desired sweetness.

In conclusion, Brown Butter Oatmeal Sandwich Cookies are a true delight for the senses, offering a harmonious blend of rich flavors and comforting textures. With their nutty oatmeal base, indulgent brown butter, and creamy filling, these cookies are a decadent treat that’s perfect for any occasion. Whether enjoyed as an afternoon snack, a dessert indulgence, or a homemade gift for someone special, these cookies are sure to bring joy to all who taste them. So, gather your ingredients, preheat your oven, and get ready to savor the blissful experience of baking and enjoying these irresistible cookies.
