Pumpkin mousse instructions
1 -Sprinkle powdered gelatin over cold water. Set aside and allow gelatin to set.
2 - Combine pumpkin puree, brown sugar, milk, egg yolks, cinnamon, ginger and nutmeg in a heat-proof bowl. Whisk well to combine.
3 - Fill a saucepan with 1" of water. Bring water to a simmer. Place bowl on top of the pan. Stir pumpkin mixture occasionally (every 3 - 5 minutes). Continue to heat the mixture until it reaches 170° F - 180° F (approximately 15 minutes).
4 - Add set gelatin to bowl and whisk until the gelatin is completely melted. Remove bowl from heat and set aside to cool (approximately ½ hour).
5 - Begin mixing egg whites using a hand mixer or stand mixer with the whisk attachment. Mix on medium speed until egg whites appear foamy. Continue mixing while slowly pouring in granulated sugar. Continue to mix until egg whites reach medium peaks.
6 - Gently fold egg whites into the cooled pumpkin mixture. Take care to not overmix and deflate the egg whites.
7 - Optional to add more moisture to cake: Make simple syrup - combine granulated sugar and water in a saucepan. Heat over medium-high heat, stirring occasionally, until the sugar has dissolved. Let syrup cool for 20 minutes. Then, using a pastry brush, apply simple syrup evenly over the spice cake layer in the springform pan.
8 - Pour mousse over cake in springform pan. Smooth top of mousse with an offset spatula. Gently tap pan on countertop to remove any air bubbles. Place pan in refrigerator until set (approximately 2 hours).
9 - Once the mousse has set, remove cake from refrigerator. Warm a knife by dipping it in hot water for about 30 seconds, then carefully run it around the inside edge of the pan to release the mousse. Gently remove cake from the pan and place it on a serving tray. Decorate as desired.
Decorations
The sky’s the limit when it comes to decorating the top of your pumpkin mousse cake! Consider one or more of these ideas:

- Whipped cream - Pipe swirls or dollops of sweetened whipped cream around the edge or in a pattern for a classic look.
- Cookies - Add some small gingerbread or sugar cookies to the top. This adds a crunch which complements the creamy pumpkin mousse
