Creating individual bars

[Sirtunes]

Hi, I changed over from pouring loafs to pouring individual bars (6 bars per mold). My mixture isn’t like pudding, more like mashed potatoes. This is frustrating me because I can’t create the swirls I want with thick batter. How can I thin my batter to make my work easier? Help!
