Notes

Brown sugar: Light brown sugar or dark brown sugar will work in this recipe.
Butter: I use salted butter. The butter should be warm enough that it dents when pressed but cool enough that it doesn't lose its shape.
Peanut butter: You'll want to use regular peanut butter like Jif or Skippy, not natural-style peanut butter, in these cookies. Either creamy peanut butter or crunchy peanut butter will work.
Vanilla extract: Feel free to use less vanilla extract, 1-2 teaspoons, if you prefer.
Kosher salt: If using table salt, use half the amount, or ½ teaspoon, of salt.
Oats: Either old-fashioned oats or quick oats will work in this recipe.
M&M candies: I use regular M&M's in these cookies.
Chocolate chips: I like to use mini chocolate chips, but you could use regular chocolate chips. You could also mix it up by using part butterscotch chips or peanut butter chips.
