Ingredients
For cookies
Cooking spray
- 1 cup
(2 sticks) butter, softened
- 1 cup
packed brown sugar
- 1/2 cup
granulated sugar
- 2
large eggs
- 1 tsp.
pure vanilla extract
- 1 1/4 cups
all-purpose flour
- 1 3/4 cups
rolled oats
- 1 tsp.
baking powder
- 1/2 tsp.
ground cinnamon
- 1/2 tsp.
kosher salt
For filling
- 1 1/8 cups
(2 1/4 sticks) butter, softened
- 2 cups
powdered sugar, sifted
- 1 tsp.
pure vanilla extract
- 2 Tbsp.
milk
Directions
- Step 1Preheat oven to 350°. Grease two 8" cake pans with cooking spray and line the bottom of the pans with parchment paper rounds.
- Step 2In a large mixing bowl with a hand mixer, beat together butter and sugars until light and fluffy. Add eggs and vanilla and mix until evenly combined. Add flour, oats, baking powder, cinnamon, and salt and stir until just combined.
- Step 3Divide dough between the two prepared pans, pressing the dough into the bottom of each pan. Bake until golden brown, about 25 minutes. Cool for 10 minutes in the pans, then invert cookies onto cooling racks and transfer to the refrigerator to cool completely, at least 30 minutes.
- Step 4Meanwhile, make filling. Beat together softened butter, powdered sugar, and vanilla until smooth and fluffy. Gradually add milk until you’ve reached the desired consistency.
- Step 5Spread filling onto one cookie in an even layer, then place the second cookie on top.
