If you don't have pumpkin-pie spice, you can instead use 2 teaspoons ground cinnamon mixed with 1/4 teaspoon each of ground ginger and nutmeg. It's very important to make sure the bread soaks up the flavorful custard to ensure a velvety consistency.
We tweaked a favorite ice cream flavor from way back to make a treat for all ages. The exceptionally moist cream-cheese pound cake gets split and filled -- three times -- with a luscious mousse flavored with pureed cooked peaches and studded with chopped fresh peaches and cherries. Because it's thickened with gelatin, the mousse gets nice and firm, then stays that way when layered in the cake -- and in every last slice.
