Fudge Filled Cookies

1/2 cup butter, softened
1/2 cup creamy peanut butter
1/2 cup sugar
1/2 cup packed light brown sugar
1 large egg
1/2 teaspoon vanilla extract
1-1/4 cups all-purpose flour
3/4 teaspoon baking soda
1/2 teaspoon salt

Fudge Filling:
1 cup milk chocolate chips
1 cup semisweet chocolate chips
1 can (14 ounces) sweetened condensed milk
1 teaspoon vanilla extract
Chopped peanuts

In a large bowl, cream butter, peanut butter and sugars until blended. Beat in egg and vanilla. In a small bowl, whisk flour, baking soda and salt; gradually beat into creamed mixture. Refrigerate, covered, 1 hour or until easy to handle.

Preheat oven to 325°. Shape into forty-eight 1-in. balls. Place in greased mini-muffin cups. Bake 14-16 minutes or until light brown. Immediately press a 1/2-in.-deep indentation in center of each cookie with the end of a wooden spoon handle. Cool in pans 5 minutes. Remove to wire racks to cool completely.

For filling, in a microwave, melt chocolate chips; stir until smooth. Whisk in milk and vanilla until smooth. Fill each cookie with filling; sprinkle with peanuts. (If desired, refrigerate remaining filling; serve warm with ice cream.) Makes 4 dozen.
