Preheat oven to 375 degrees F; adjust oven rack to the upper third of the oven. Line baking sheet with parchment paper; set aside.
Bring the butter to a boil in a medium saucepan over medium heat. Reduce the heat so the butter slows to a gentle boil, stirring occasionally, for 3 to 4 minutes, or until the solids on the bottom of the pan turn light brown. Remove from heat.
Add the brown sugar, corn syrup, milk and salt to the butter and stir to blend well. Stir in the oats, flour and vanilla, then fold in the almonds.
Drop teaspoons of the batter onto the baking sheets, spaced about 3 inches apart. Bake for 6 to 8 minutes, or until the cookies are golden brown all over and slightly darker at the edges. Transfer the baking sheets to a cooling rack and let sit until the cookies firm up, about 5 minutes. Using a spatula, gently transfer the cookies to wire racks until cool. Store the cookies in an airtight container at room temperature for 2 weeks, or freeze for up to 2 months.
Notes
Note: While I always think "bigger is better" when it comes to cookies, resist using more batter than the recipe calls for, as the batter will spread significantly while baking. The batter may start to get stiff while you're scooping and baking the cookies, but that's okay.Nutritional values are based on one cookie
