Heavenly Toffee Chip Fudge

1/2 cup LAND O LAKES® Butter
1/4 cup milk
1 (6 ounce) package (1 cup) semi-sweet real chocolate chips
3 cups confectioners' sugar
1 teaspoon vanilla extract
1/2 cup toffee chips

Topping
2 tablespoons toffee chips

Combine butter, milk and chocolate chips in large microwave-safe bowl. Microwave on HIGH or until butter and chocolate chips are melted (1 1/2 to 2 minutes). Stir in confectioners' sugar and vanilla extract; beat at medium speed, scraping bowl often, until smooth (2 to 3 minutes).

Stir in 1/2 cup toffee chips by hand. Spread in buttered 8-inch square baking pan. Sprinkle 2 tablespoons toffee chips over top; gently press into fudge. Cover; refrigerate until firm (1 to 1 1/2 hours). Cut into squares. Store refrigerated in airtight container.

NOTE: For easy cutting, line pan with aluminum foil, extending foil over sides of pan; butter foil. To serve, lift foil and fudge out of pan; cut into squares. Place squares in paper candy cups.

For making on stove top: Combine butter, milk and chocolate chips in 2-quart saucepan. Cook over low heat, stirring occasionally, until butter and chocolate chips are melted (5 to 10 minutes). Place chocolate mixture in large mixer bowl. Stir in confectioners' sugar and vanilla extract. Continue as directed above.

Makes 3 dozen candies.
