Step 1

Preheat oven to 350°F and line a baking sheet with parchment paper.

Step 2

In a medium saucepan over medium heat, melt the butter and brown sugar into a thick paste, stirring frequently.

Step 3

Remove from heat and stir in flour, vanilla, and salt. Let cool 10 minutes.

Step 4

Add egg and oats and mix with a fork until well combined.

Step 5

Spoon out onto prepared baking sheet in 1 tablespoon portions 2 inches apart. Using the back of a spoon, spread each cookie into a thin circle so oats are in a single layer.

Step 6

Bake until edges begin to turn golden brown, about 8 minutes. Remove from oven and let cool completely on parchment paper.

Step 7

Once cool, cookies should peel easily from parchment. Enjoy!

Step 8

Note: To store, layer between pieces of parchment paper in an air-tight container.
