Ingredients

1/3 cup packed light-brown sugar 

1/4 cup (1/2 stick) unsalted butter, melted 

1 large egg 

1/2 teaspoon vanilla extract 

1 1/2 cups rolled oats, (not quick-cooking) 

1/2 cup sliced almonds 

Nonstick cooking spray 

Preparation

Preheat oven to 350 degrees. Line two baking sheets with parchment paper.

In a large bowl, whisk brown sugar, butter, egg, and vanilla until smooth. Mix in oats and almonds.

Drop mixture by level tablespoons onto prepared baking sheets, spacing about 2 inches apart. Spray the underside of a metal spatula with nonstick cooking spray, and use to flatten cookies into 2 1/2-inch disks.

Bake until golden, 14 to 16 minutes. Cool completely on baking sheets. (Handle with care; cookies are fragile.)
