This is an old recipe for chocolate cookies with a surprise peanut butter filling. Using half shortening and half butter prevents the cookies from spreading too much while optimizing flavor.
⅔cupsemi-sweet chocolate chips (the minis are best)(114 grams)
Instructions
Preheat oven to 350 degrees F. Line 2 large cookie sheets with parchment paper.
Prepare filling first. Mix together peanut butter and powdered sugar. Drop marble size balls of peanut butter mixture onto a waxed paper lined plate and set in freezer. This is to help make the peanut butter balls more manageable.
Stir flour, cocoa powder, baking soda and salt together in a mixing bowl. Set aside.
In a large mixing bowl, beat butter, shortening and both sugars together using with an electric mixer. Beat until creamy, scraping sides of bowl; beat in vanilla. Add egg and beat until it is mixed in. Add flour mixture and stir with a mixing spoon until most of flour is incorporated. Add chips and continue to stir until remaining flour mixture is incorporated. If dough seems very sticky, chill it for about a half hour (it shouldn’t be too sticky).
Using a rounded tablespoon, scoop up mounds of dough and wrap each mound around one of your little blobs of peanut butter mixture. Seal the peanut butter ball in the dough the best you can and place on cookie sheet spacing about 2 inches apart. Bake one sheet at a time for about 12 minutes.
Let cookies cool on sheets for 3 minutes, then lift with a metal spatula and set on wire racks to cool and set.
