What kids, regardless of their "real" age, don't love peanut butter, marshmallow cream, and chocolate all wrapped up in one? On a recipe development grocery run, I spied the fluffy stuff staring at me brazenly from a shelf, right next to the peanut butter. My neighbor Lucie had recently turned me on to the wonders of chocolate graham crackers, so that became the crust that cradles this decadent tart filled with a mousse-like blend of cream cheese, marshmallow cream, and peanut butter.
It can be fully assembled ahead of time and chilled overnight. However, save whipping the cream until just a few hours before service. This is heartbreakingly good and beautiful to look at! Its richness and pumpkin-colored hue are perfect for fall and winter indulgences.
