I have never seen a peach cake mix, however, a good idea is to take a white cake mix, substitute part (if not all) the liquid (not the oil though) with peach juice from canned peaches and dice the peaches into the cake. A make your own peach cake.
Usually cake mix is meant to be a moisture cake, whereas pound cake is dense. Pound cake is easier to stack/sculpt. Cake mix usually has better flavor, whereas pound cake mix would require a syrup to help with flavor and moisture.
First you take a red velvet cake mix and you follow the instructions on the cake box. Then you take a cupcake pan and pour the batter in then you bake for how long it tells you to. Then bam you have your delicious Red Velvet Cupcakes! :)
