The Venn diagram of cheesecake and Southern-style banana pudding has a large swath of overlap. I wanted a dessert that was sturdy enough to eat out of hand, so I skipped the standard round cheesecake pan and developed this banana pudding cheesecake recipe in bar form. Instead of graham crackers for the base, here comes a box of Nilla wafers, in deference to the banana pudding canon. Many modern banana pudding recipes use boxed pudding mix combined with condensed milk. Most cheesecakes start with cream cheese whipped with granulated sugar, which helps the cream cheese smooth out into billowing fluff.
