Mix cake ingredients as directed and bake in a large jellyroll pan for 15 to 20 minutes until toothpick comes clean from center. Cut the cake into tiny cubes.

In a large bowl or stand mixer, beat heavy cream, confectioners' sugar, and pudding mix until light and fluffy, about 3-4 minutes.

Assemble the trifles by adding a layer of cubed cake to some small glasses, then piping on a layer of the frosting, then a layer of nuts, then a layer of 5 of the unwrapped Hershey's Kisses in Carrot Cake, then a layer of cake, a layer of frosting, and topping with an unwrapped Hershey's Kisses and some chopped pecans.
