Let me just start by saying these two quotes "I could eat everyone of these!" from my daughter. "Little sandwiches of love" from husband--that is great advertisement for a recipe!!
1 1/2 cup flour
1/2 cup unsweetened cocoa powder
1/2 teaspoon baking soda
1/2 cup butter softened
1/2 cup peanut butter
1/2 cup granulated sugar
1/2 cup packed brown sugar
1 egg
1 Tablespoon milk
1 teaspoon vanilla
3/4 cup powdered sugar
1/2 cup peanut butter
2 Tablespoon sugar ( I omitted this, they were sweet enough without it)
Preheat oven to 350 degrees. In a medium bowl stir together flour, cocoa powder and baking soda set aside.
In a large bowl combine butter and the 1/4 cup peanut butter. Beat with an electric mixer on medium to high speed for 30 seconds. Add the 1/2 cup granulated sugar and brown sugar. Beat until well combined, scraping side of bowl occasionally. Beat in egg, milk and vanilla until combined. Beat in flour mixture. Shape dough into 32 balls, each about 1 1/4 inches in diameter. Set aside (I made 36).
In a small bowl combine powdered sugar and the 1/2 cup peanut butter. Beat until smooth, kneading by hand if necessary. Shape mixture into 32 balls (i made 36).
For each cookie, flatten a chocolate dough ball, top with a peanut butter ball. Shape dough around peanut butter ball to enclose. (This part is really sticky and if they weren't so good I would complain about it) Place balls 2 inches apart on a ungreased cookie sheet (I lined mine with parchment paper). Flatten with the bottom of a glass dipped in the 2 tablespoons of sugar (again, I didn't see a reason to do this, I flatten with my fingers).
Bake in preheated oven about 8 minutes (I baked for 10) or just until set and surfaces slightly crack. Cool on cookie sheet for 1 minute, transfer to wire rack and cool. Makes about 32 cookies (I got 36).
