Jumbo Peanut Butter Cup Cookies

Preheat oven to 350ºF.

Cream butter and sugars together on medium speed for 3 minutes. Add egg whites and mix for 1 minute. Add peanut butter and vanilla and mix for an additional 1 minute.

Sift flour, baking soda, and salt together in a medium bowl. Slowly add flour mixture to butter mixture on slow speed; mix just until incorporated. Use a spatula to mix in chopped Reese’s peanut butter cups.

Use an ice cream scoop to measure out perfect mounds of cookie dough, and then place 6 raw cookies on a Silpat or parchment-paper-lined baking sheet. Smash each cookie down with your palm, and then bake for 11 minutes. Allow cookies to rest for 3 minutes before removing to a baking rack to cool.
