You'll need peanut butter, oats, and a few other ingredients to make this easy recipe. Let's get started!
In a medium bowl, mix butter, peanut butter, brown sugar, and granulated sugar using a fork until smooth.
Stir in the egg and the vanilla. Make sure it is fully combined.
Gently incorporate the oats, flour, and baking soda. Mix until just combined.
Fold in the toffee pieces.
Create cookie dough balls using a 2 tbsp scoop and place them 2 inches apart on a baking sheet.
Bake for 9 minutes or until the middle of each cookie is just set and the edges start to brown.
Once baked, immediately garnish the cookies with sea salt if desired. Then let cool on a wire rack.
Cool completely on a rack or place them on a serving plate and enjoy warm.
