Peanut butter and chocolate is a classic combination that never gets old. These Peanut Butter Oatmeal Chocolate Chip Cookies are the perfect blend of sweet and salty, chewy and crunchy, and are sure to be a hit with anyone who tries them.
Place the melted butter and peanut butter into a large mixing bowl. Add the two sugars and whisk to combine.
Next, add the egg, egg yolk, and vanilla extract to the butter/sugar mixture. Whisk well to combine.
Add the oats, oat flour, flour, baking soda, and salt to the rest of the ingredients and mix until a dough forms.
Finally, stir in the chocolate chips and chopped chocolate until it is evenly distributed throughout the cookie dough.
Cover the cookie dough tightly with plastic wrap and chill for at least 15 minutes to half an hour.
Preheat oven to 350 degrees F. Line two baking sheets with parchment paper.
Use a large cookie scoop to drop 3 tablespoon-sized dough balls onto parchment lined baking sheets. Place the cookie dough balls 2 inches apart (no more than 4 cookies per tray).
Bake the cookies in a preheated for 13-15 minutes, or until edges are set and centers are slightly underbaked.
Allow the cookies to cool for 5 minutes on the baking sheet before transferring to a wire rack to cool completely. Sprinkle with flaked sea salt and enjoy!
Notes
Measure all of your ingredients accurately. I like to use a kitchen scale to weigh out all of my ingredients. Make sure the melted butter is slightly cool and the egg and egg yolk are at room temperature before beginning.
Don't skip out on chilling the dough! Chilling the dough will help the dry ingredients absorb the wet ingredients and prevent the cookies from spreading too much during baking.
