This pumpkin gingersnap icebox cake with dulce de leche is one of my favorite no bake pumpkin desserts for the fall season. This pumpkin freezer cake is layers of dulce de leche filled gingersnaps, pumpkin cream, and whipped cream, giving it a pumpkin mousse texture.
*Pumpkin Pie Spice: If you prefer to use pumpkin pie spice, use 1 1/2 tsp ground cinnamon + 1 tsp pumpkin pie spice.
**You can add the reserved whipped cream on top of the icebox cake before freezing it for at least 4 hours if you prefer. I like to add it before serving, because I like the texture of the soft whipped cream with the thick pumpkin cream. However, if it’s easier, you can add it before freezing.
