Line your baking sheet with parchment paper and preheat the oven to 350°F.
In a medium saucepan, melt the butter and brown sugar over medium heat until it’s a thick brown liquid. They need to melt; they don’t need to fully mix together.
Remove pan from heat and stir in the almond extract, salt, and flour.
Allow to cool for 10 minutes.
Next, add the egg and incorporate with a fork.
Once the egg is mixed in, add the oats. Stir until the oats are covered in the mixture.
When you have your oat mixture ready, it’s time to put the cookies on the pan. Drop a tablespoon of batter onto the parchment paper, leaving at least 2 inches around each spoonful.
Use the back of the spoon to spread each cookie into a thin circle with the oats being in a single layer, not piled on top of each other. Spray the back of your spoon with oil between cookies.
Bake for 8 minutes or until cookies are crispy and golden brown around the edges.
When cookies are cooled, you can dust them with powdered sugar or use them to make cookie sandwiches with Nutella in the middle. Both the powdered sugar and Nutella are optional.
