This simplified version for Pumpkin Mousse makes pumpkin possibilities a breeze!

Pumpkin and Chocolate is usually my jam but this White Pumpkin Mousse Layer Cake is a total win!

Pumpkin Mousse Layer Cake

I have a couple options for the white cake recipe listed below

Be sure to check out each recipe to decide which one is going to work best for you!

Complete with pumpkin spiced buttercream and a white chocolate ganache drip

Gingersnap cookies filled with pumpkin mousse for the best final touch!

Notes for Success:

In the video tutorial you will see that I like to fill my mousse cakes as soon as the mousse is finished
By using an acetate cake strip in a ring mold; rather than letting it set in the refrigerator and then building the cake later

Of course you can build the cake traditionally with a buttercream ring dam to hold in that soft filling if you prefer.

I am baking the white cake recipe into 2-8″ cake pans for a 2 layer cake this time

Gingersnap cookie garnish is optional and by making 1 recipe you will have lots of extra cookies, which is not exactly a bad thing!
