Cake Ingredients

  • 1/2 cup sugar Sweetens the cake, balancing the richness of the mousse.
  • 1/2 cup flour Provides the structure needed for the cake's airy texture.

Mousse Ingredients

  • 2 lbs sour cream The heart of the mousse for its luxurious creaminess.
  • 1 1/2 cups sugar Enhances sweetness, making every bite irresistible.
  • 15 oz sweetened condensed milk Introduces a rich, creamy sweetness that elevates the filling.
  • 1/2 cup milk Helps to dissolve the gelatin, creating a perfect mousse consistency.
  • 4 packets Knox Gelatine Essential for giving the mousse its wonderfully firm texture.
  • 2/3 cup Cool Whip Adds a lightness that complements the rich mousse beautifully.

Ganache Ingredients

  • 1 stick unsalted butter Adds richness to the ganache, making it smooth and glossy.
  • 1 cup semi-sweet chocolate chips Provides a rich flavor that contrasts beautifully with the sweet mousse.
  • 1 cup heavy cream Creates a silky texture for the ganache that melts in your mouth.

Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C). Grease and flour a cake pan.
  • In a mixing bowl, combine the 1/2 cup of flour and 1/2 cup of sugar. Mix well to combine.
  • Pour the mixture into the prepared cake pan and bake for about 20 minutes or until it’s golden and springs back when touched lightly.

Mousse Preparation

  • As the cake cools, begin to prepare the mousse. In a medium saucepan, combine 1/2 cup milk and the gelatin. Let it sit for a few minutes, then gently heat until dissolved.
  • Stir in the 2 lbs of sour cream, 15 oz of sweetened condensed milk, and 1 1/2 cups of sugar until everything is well blended and smooth.
  • Fold in the 2/3 cup of Cool Whip carefully, incorporating air gently to keep the mousse light and fluffy.

Assemble the Cake

  • Once the cake has cooled, slice it in half horizontally to create two layers.
  • Place one layer back into the cake pan and spread half of the mousse over it, then carefully add the second layer of cake on top. Finish with the remaining mousse spread evenly over the top.
  • Chill in the refrigerator until the mousse sets, usually around 4 hours or overnight if you can wait that long!

Prepare the Ganache

  • Before serving, melt the stick of unsalted butter and combine it with the 1 cup of semi-sweet chocolate chips and 1 cup of heavy cream. Stir until smooth and glossy.
  • Drizzle this ganache over the chilled cake.

Notes

This cake can be made ahead of time and actually tastes better after sitting for a while as flavors meld. If you want to re-experience that first bite, let it sit out for a bit to warm slightly—it'll feel brand new.
