1½ cups all-purpose flour
½ cup unsweetened cocoa powder
½ tsp. baking soda
½ cup butter, softened
½ cup sugar
½ cup packed brown sugar
¼ cup peanut butter
1 egg
1 Tbsp. milk
1 tsp. vanilla
3/4 cup sifted powdered sugar
½ cup peanut butter
2 Tbsp. granulated sugar
Directions:
Preheat oven to 350F. Line cookie sheets with parchment paper.
Stir together flour, cocoa powder and baking soda. Set flour mixture aside.
In a large mixing bowl, beat together butter, sugar, brown sugar, and the ¼ cup peanut butter with an electric mixer until combined. Add egg, milk and vanilla; beat well. Gradually beat in flour mixture. Form chocolate dough into 32 balls about 1¼ inches in diameter. Set aside.
In a medium mixing bowl, combine powdered sugar and remaining ½ cup peanut butter till smooth. Shape into 32 (3/4-inch) balls. I used chunky peanut butter, so it was a little on the dry side when I mixed this up, so I just added a little milk and it worked great.
Slightly flatten a chocolate dough ball and top with a peanut butter ball. Shape the chocolate dough over the peanut butter filling, completely covering the filling. Roll dough into a ball. Repeat with the remaining chocolate dough and peanut butter filling.
Place 2 inches apart on prepared cookie sheets. Lightly flatten with bottom of glass dipped in remaining sugar.
Bake at 350F for 8 minutes, or until just set and surface is slightly cracked. Let cookies stand for 1 minute. Transfer cookies to a wire rack to cool. Makes 32 cookies.
