I really don't think it would be necessary to add in extra calories specifically for the cardio session. If you are bulking you are likely already in a surplus.
Just do the cardio for the benefits you mentioned and as long as you don't go overboard, you won't have to stress muscle loss.
James 1:16-17 ESV
Do not be deceived, my beloved brothers. Every good gift and every perfect gift is from above, coming down from the Father of lights
