How to Make Carrot Cake Mousse Layer Cake
Step 1: Prepare the Cake Batter
Start by preheating your oven to 350°F (175°C). In a large bowl, whisk together all the dry ingredients: flour, baking powder, baking soda, cinnamon, nutmeg, and salt. This blend of spices and leavening agents will give your cake the perfect lift and flavor foundation. In a separate bowl, beat together the oil, brown sugar, granulated sugar, and eggs until combined and slightly fluffy, ensuring your cake turns out moist and tender.
Step 2: Add the Carrot and Pineapple
Fold the grated carrots and drained crushed pineapple into the wet mixture carefully. These two ingredients bring much more than flavor—they infuse moisture and a subtle fruity tang that keeps the carrot cake delightfully fresh. Once combined, gently mix the wet and dry ingredients together until just incorporated, taking care not to overmix to keep the texture light.
Step 3: Bake the Carrot Cake Layers
Divide the batter evenly between two well-prepared 8-inch cake pans. Bake in the preheated oven for about 25 minutes or until a toothpick inserted into the center comes out clean. After baking, allow the cakes to cool completely on wire racks. This cooling step is vital before layering to ensure your mousse won’t melt or slide.
Step 4: Whip the Cream Cheese Mousse
In the meantime, prepare the cream cheese mousse by beating the cream cheese with sugar until smooth and fluffy. In a separate bowl, whip the heavy cream with the vanilla until soft peaks form. Gently fold the whipped cream into the cream cheese mixture. The result is a light, dreamy mousse that balances richness with a cloud-like texture, making the cake irresistibly elegant.
Step 5: Assemble the Carrot Cake Mousse Layer Cake
On your serving plate, place one cake layer and spread a generous amount of cream cheese mousse over it. Top with the second cake layer and finish by spreading more mousse evenly over the top and sides. Smooth everything with a spatula for a clean, polished look. Refrigerate the assembled cake for at least three hours to let the mousse set perfectly and the flavors meld together for that melt-in-your-mouth experience.
How to Serve Carrot Cake Mousse Layer Cake

Garnishes
To highlight the charm of this Carrot Cake Mousse Layer Cake, consider adding delicate edible carrot decorations made from fondant or marzipan for a playful yet elegant touch. A light dusting of cinnamon or grated nutmeg on top can bring out the warm spices, and a few toasted walnut halves around the edges add a satisfying crunch and visual contrast.
Side Dishes
This cake pairs beautifully with a simple cup of freshly brewed coffee or a smooth chai tea, complementing the spices and sweetness. For a special brunch or celebratory meal, serve alongside fresh berries or a light fruit salad to provide a refreshing balance to the rich mousse and cake layers.
Creative Ways to Present

For parties, create a dessert bar where guests can customize their slices with toppings like chopped nuts, shredded coconut, or caramel drizzle—it’s a fun and interactive way to enjoy this layered indulgence.
Make Ahead and Storage
Storing Leftovers
Once your Carrot Cake Mousse Layer Cake is assembled and chilled, store any leftovers in an airtight container in the refrigerator. It will stay fresh and delicious for up to four days, making it perfect for enjoying over several days without losing that moist texture or creamy mousse quality.
Freezing
If you want to keep this dessert longer, you can freeze it. Wrap the cake tightly in plastic wrap and then foil to protect it from freezer burn. It can be frozen for up to two months. When ready to enjoy, thaw overnight in the refrigerator to preserve the texture of the mousse and the crumb of the cake layers.
Reheating
This cake is best enjoyed chilled, so reheating is not recommended as it can alter the texture of the mousse. Instead, allow it to sit at room temperature for about 15 minutes before serving, which enhances the flavors without compromising the mousse’s delicate structure.
FAQs
Can I use regular whipped cream instead of cream cheese mousse?
While whipped cream alone is lighter, it won’t provide the same tangy richness and stability that the cream cheese mousse offers in this recipe. The mousse balances the sweet spices and adds that signature creamy texture to the cake.
What is the purpose of pineapple in the cake?
Crushed pineapple adds moisture and a subtle fruity sweetness, which keeps the carrot cake tender and adds a delicate tang that brightens the overall flavor profile.
Can I make this cake gluten-free?
You can substitute the all-purpose flour with a gluten-free flour blend, but be sure it includes xanthan gum or another binder to help maintain the cake’s structure and moisture.
How long does it take for the mousse to set properly?
Chilling the assembled Carrot Cake Mousse Layer Cake for at least three hours is essential to let the mousse firm up, ensuring clean slices and a stable structure when serving.
Is it possible to use a different mousse flavor?
Absolutely! While the cream cheese mousse is classic and complements the carrot cake perfectly, feel free to experiment with flavors like orange or ginger mousse to add your own twist to this layered favorite.
