Why You’ll Love This Recipe

Oatmeal cookies have always been a nostalgic favorite in my home. I remember baking them with my grandmother, the kitchen filled with the warm aroma of cinnamon and brown sugar. But adding a creamy filling? That takes them to the next level. These cookies are soft, slightly chewy, and have just the right amount of spice. The creamy center makes them even more irresistible!

Unlike store-bought versions, these cookies aren’t overly sweet, and you can customize the filling to your liking—whether it’s classic vanilla, a tangy cream cheese frosting, or even peanut butter.

Key Ingredients and Substitutions

Oats:

Old-fashioned rolled oats give the best chewy texture. Quick oats work but will make the cookies softer.

Brown Sugar:

Adds moisture and a deep caramel-like sweetness. Light or dark brown sugar works.

Butter:

Keeps the cookies rich and tender. Use dairy-free butter for a vegan option.

Eggs:

Help bind the dough. Swap with flax eggs (1 tbsp flaxseed meal + 2.5 tbsp water per egg) for a vegan version.

Cinnamon & Vanilla:

Enhance the warm, comforting flavor.

Baking Soda & Baking Powder:

Ensure the perfect rise and softness.

Filling Options:

• Classic vanilla buttercream
• Cream cheese frosting for a tangy twist
• Peanut butter or marshmallow fluff for extra indulgence

Step-by-Step Instructions

Step 1: Mix the Wet Ingredients

Cream together butter and brown sugar until light and fluffy. Add eggs and vanilla, mixing well.

Step 2: Combine the Dry Ingredients

In a separate bowl, whisk together flour, oats, baking soda, baking powder, cinnamon, and salt.

Step 3: Make the Dough

Gradually add the dry ingredients to the wet mixture. Stir until just combined.

Step 4: Bake the Cookies

Scoop dough onto a lined baking sheet. Bake at 350°F (175°C) for 10-12 minutes until golden.

Step 5: Prepare the Filling

While cookies cool, beat together butter, powdered sugar, vanilla, and milk until smooth.

Step 6: Assemble

Spread or pipe filling onto one cookie and sandwich with another. Enjoy!

Expert Tips for the Best Oatmeal Sandwich Cookies

1. Use Softened Butter

Creaming softened butter with sugar creates a tender, chewy texture.

2. Don’t Overbake

The cookies should be slightly soft when they come out of the oven. They’ll firm up as they cool.

3. Chill the Dough

For thicker cookies, refrigerate the dough for 30 minutes before baking.

Serving Suggestions

These cookies pair well with:

• A glass of cold milk
• A drizzle of caramel for extra sweetness
• A dusting of cinnamon sugar for a bakery-style touch

Storage and Reheating Tips

Refrigerating:

Store in an airtight container for up to 5 days.

Freezing:

Freeze assembled cookies or unfilled cookies for up to 3 months.
