Keto Pumpkin-Spice Mousse Tart with Chocolate-Almond Crust

Move over pumpkin pie, this lush yet light dessert has a cookie-like chocolatey crust and fragrant autumnal aromas. The pumpkin filling can also be served on its own, spooned into small bowls or stemmed glasses for a more elegant presentation. Note: this recipe calls for a tart crust, so either prepare the recipe below, Keto Chocolate-Almond Tart Crust recipe beforehand, or use another keto-friendly pie shell.
Serves 12 One Serving: 1 slice - including crust

Whether you decide to use erythritol or not, remember that all sweeteners should be consumed in moderation, and your keto diet should primarily focus on nutritious whole foods. Learn more: Erythritol Explored: Weighing the Pros and Cons.

Instructions

FOR THE TART

  • In the bowl of a stand mixer fitted with the paddle attachment, combine the cream cheese and 1/4 cup of the powdered sweetener. Beat on low speed for 2 minutes. Add the pumpkin puree, pumpkin pie spice, and 1 teaspoon of the vanilla. Beat on low speed until incorporated, scraping down the sides of the bowl once or twice, about 1 minute. With the mixer on low, slowly add 1/2 cup of the heavy cream. Beat just until incorporated and fluffy, about 2 minutes. Do not overbeat. Spoon the pumpkin mousse into the prepared tart crust, smooth it out evenly with a spatula, and chill for 1 hour.
  • In the bowl of a clean stand mixer fitted with the whisk attachment, whip the remaining 1/2 cup of heavy cream, 2 tablespoons of powdered sweetener, and 1/2 teaspoon vanilla until soft peaks form; do not overbeat. Spoon the whipped cream over the chilled pumpkin mousse in decorative dollops. Finish with a sprinkle of pumpkin spice. Chill for at least 1 hour. Serve.

FOR THE CHOCOLATE-ALMOND TART CRUST

  • Preheat oven to 375°F (190°C). In the bowl of a food processor fitted with the steel blade, place the almonds, coconut flour, sweetener, cocoa powder, and salt. Pulse until the almonds are medium-fine, like coarse cornmeal, and there are still visible bits of the almonds. Add the butter and pulse until the mixture starts to clump, 6 to 8 pulses. Sprinkle 1 tablespoon of cold water over the mixture and pulse a few more times until it mixes together.
  • Remove the dough to a 9-inch tart pan with a removable bottom. Press the crust evenly outward working it up the sides. The crust should be about 1/4 inch thick. You can use a flat-bottomed metal dry measuring cup to help even the crust out and get it evenly into the corners.
  • Place the tart pan on a rimmed baking sheet and bake in the oven on the middle rack until dry and set, 18 to 20 minutes. Set aside to cool.

    Unfortunately, my crust stuck to the bottom of the pan!

    • Next time use a parchment the size of the round bottom of pan

  2. The picture of the tart was definitely deceiving – the mousse was less than half than how it was pictured and I used the correct size spring form pan. It tasted Ok but think I would double the mousse recipe and maybe add a little more pumpkin purée if I make it again??

    Thought the crust was easy and tasty. Not wild about the filling. Next time I would make a chocolate (keto) mousse for filling: Whipped heavy cream, 1-2 TBLS unsweetened cocoa, 1/4 tsp cinnamon, Lakanto monk fruit (keto friendly) sweetener to taste.

  4. 5 stars
    This is great, but mine did NOT add up to only 7 total and 3 net carbs. That was massively disappointing. Otherwise really, really good.

    • Some brands have different carbs and calories, can you let us know where you found the difference?

    So I started thinking about my Thanksgiving menu and remembered that I made this pie last year and it was to die for! I brought it to a gathering of non-keto family and friends and it was a big hit. You would never think of it as a keto dessert. I’m making again this year for sure.

  6. 5 stars
    I don’t love the idea of mousse or pumpkins spice, but when a friend made this for me over the holidays, I changed my mind. This dessert is EVERYTHING.
