1 box fudge brownie mix
2 c. chocolate chips
2 lg. boxes chocolate instant pudding
5 c. cold milk
2 lg. containers cool whip
1 c. miniature chocolate chips
Bake brownies according to directions, except fold in 2 c. chocolate chips before baking. Bake in greased 9x13 pan for 28 minutes. Do not overbake. Cool completely. Cut into 1/2 inch cubes.
Make pudding mixture as follows: Mix pudding and milk together and stir with wire whip or mixer 1 to 2 minutes. Fold in 3 cups of Cool Whip and 1 cup miniature chocolate chips. Place 1/2 of brownies in bottom of large trifle bowl, then 1/2 of pudding mixture, 4 Heath bars (crushed), and a layer of Cool Whip. Repeat layers. Decorate with crushed Heath bars. Cover with plastic wrap and refrigerate overnight.
Tip: Freeze Heath bars; crush in wrapper with wooden mallet or handle of table knife. I used large punch bowl for serving.
