Line an 8-inch baking dish with wax paper. Place 9 tablespoons of milk in a microwave-safe bowl. Add chocolate chips, cocoa, and coffee, then microwave on high for 1 minute or until everything has melted. Stir in 1/2 teaspoon vanilla and spread into the prepared pan.
Combine the remaining milk, peanut butter chips, and peanut butter in a different microwave-safe bowl. Microwave on high for 1 minute or until it's all melted. Stir in the remaining 1/2 teaspoon vanilla. Spread evenly over the chocolate layer, and sprinkle with peanuts. Cover and let chill 2 hours. When it's ready, cut it into 25 squares.
