Prepare & bake brownie mix as directed on the package for 8″ or 9″ square baking pan. Remove from the oven. Immediately use round handle of a wooden spoon to poke holes at 1″ intervals down through the brownies to the pan.
Pour cold milk into a large bowl. Add the pudding mix. Beat with a wire whisk for 2 minutes. Stir in a few drops of each color food coloring to tint the mixture orange.
Quickly pour about ½ of the thin pudding evenly over the warm brownies & into the holes. Let remaining pudding mixture stand to thicken slightly. Spread the remaining pudding over top of the brownies to “frost”.
Refrigerate for 1 hour or until ready to serve. Cut into 2″ squares. Cut each square diagonally into triangles.
