Gingersnap Sweet Potato Mousse with Marshmallow Fluff

These individual Gingersnap Sweet Potato Mousse with Homemade Marshmallow Fluff desserts first begin with a layer of crushed gingersnap cookies.  Next comes a smooth and luscious sweet potato mousse, followed by a cloud of homemade marshmallow fluff and another layer of mousse.   The finishing touch is toasted mini marshmallows and more crushed gingersnaps.  In other words, the perfect layered holiday dessert.

Now that the calendar has turned to November, I’m all about Thanksgiving prep.  I’ve gathered up my food magazines, my Thanksgiving binder (yes, I have one) and I’m ready to start planning  my menu.  I usually add one to two new dishes to my menu each year and this year, one of those new dish spots has already been reserved for this Gingersnap Sweet Potato Mousse with Homemade Marshmallow Fluff.

Sweet potatoes always have a starring side dish role at our Thanksgiving table in my Make Ahead Sweet Potato Casserole, but this year I wanted to try including them as a dessert option.  But not as a pie.  For some reason, the thought of sweet potato pie just never sits well with me.  Instead, this Gingersnap Sweet Potato Mousse with Homemade Marshmallow Fluff is similar to my beloved side dish with the lightly sweetened sweet potatoes and mini marshmallow topping, but also includes additional layers of flavor that truly makes it standout from the other options at the dessert table.

These individual desserts first begin with a layer of crushed gingersnap cookies which provide a delicious and contrasting crunchy, spicy flavor to the rest of the dessert.  Next comes a smooth and luscious sweet potato mousse that’s light and airy and flavored with brown sugar and vanilla.  But the next layer of this Gingersnap Sweet Potato Mousse with Homemade Marshmallow Fluff earns the honor of being my favorite.   I have three words for you, my friend.  Homemade.  Marshmallow.  Fluff.

Marshmallows are an everyday sweet treat and a staple for holiday recipes, so why not include two layers of them in a dessert, I say?  This homemade marshmallow fluff is so insanely easy that I’m wondering why I’ve never made it before.  You simply add six cups of Campfire® Mini White Marshmallows and two tablespoons of corn syrup to a bowl and take it for a quick spin in the microwave.  You then stir the mixture together with a spatula and TADA!  Homemade marshmallow fluff.  It’s like a fluffy cloud layer sandwiched between two layers of sweet potato of mousse.  I mean, how can you go wrong?!

Campfire® has fun, festive Marshmallows for every season, I mean, check out their Cherry Roasters that I put to use in my Cherry Cola S’mores Brownies.  But those Mini White Marshmallows are classic for a reason and absolutely perfection in this holiday recipe.  And of course, to make it a true sweet potato dish in my eyes, a sprinkle of said Mini White Marshmallows sits on top of the second layer of mousse and is then lightly toasted or charred – depends on how heavy handed you get with your kitchen torch! – and then sprinkled with additional crushed gingersnap cookie.  In other words, this Gingersnap Sweet Potato Mousse with Homemade Marshmallow Fluff needs to be on your Thanksgiving menu, too.
