I got this recipe from the Hershey's Chocolate Lovers Cookbook (a definite Tnt recipe). Hope this is what you were looking for....

Heat oven to 350* Grease and flour 13 x 9 x 2" baking pan.

Stir together flour, baking powder, and salt; set aside.

In large mixing bowl, beat butter, brown sygar, and vanilla until creamy; add eggs, beating well. Stir in flour mixture until well blended; divide batter in half.

Stir chocolate chips into one part; spread into prepared pan. Into remaining batter, stir cocoa, oil and vanilla milk chips; spread gently and evenly over vanilla layer.

Bake 35 - 40 minutes or until brownies begin to pull away from side of pan. Cool completely in pan on a wire rack; cut into bars. Using tines of a fork, drizzle Vanilla Chip Drizzle over the top of bars; let stand until firm.

About 36 brownies

Vanilla Chip Drizzle

In small microwave safe bowl, place vanilla milk chips and shortening. Microwave at High (100%) 30 seconds; stir vigorously. If necessary, microwave at High additional 15 seconds until chips are melted when stirred. Use immediately.
