How to make Apple Pecan Caramel Mousse Cake

The recipe for this incredible dessert is quick and each step is easy to prepare. Begin by preparing a delicious apple cake, then continue with an apple, pecan caramel crunchy layer and finish with a salted caramel mousse. 

How to make the apple cake

Start by preheating your oven to 350°F (180°C). Grease an 8-inch (20cm) pan with butter and line it with parchment paper for easy removal.

In a medium-sized bowl, combine flour, baking powder, baking soda, cinnamon, and salt. Set this mixture aside for later.

In a larger bowl, add an egg, brown sugar, vanilla extract, and vegetable oil. Use  whisk or a hand mixer to mix them together until they are well combined. 

Gradually add the flour mixture to the wet ingredients. Toss in diced apples and stir until everything is thoroughly mixed.

Pour the batter into the prepared pan and smooth it out evenly.

Bake the cake in the preheated oven for 13-15 minutes. To check if it’s done, insert a toothpick into the cake – it should come out clean. Allow the cake to cool completely before inverting  it to a serving plate.

Prepare the caramel pecan apple crunchy layer

 Lower the oven temperature to 300°F (150°C). Spread pecans on a parchment paper-lined baking sheet and toast them in the oven for 15 minutes. Once cooled, chop the pecans into smaller pieces. Peel, core and cut an apple into small pieces. 

In a medium heavy-bottomed saucepan over medium-high heat, combine sugar and water. Allow it to cook without stirring until the sugar melts and turns into a rich caramel color. Add cream – it will bubble a bit. Toss in the apple pieces, butter, pecans, and salt. Stir constantly for about 2 minutes.

Spread this pecan apple caramel filling over the apple sponge cake, leaving a ½ inch (1cm) border and refrigerate while you move on to the next step.

Prepare the caramel mousse

Start by making the salted caramel sauce. Combine sugar and water in a medium heavy-bottomed saucepan over medium-high heat. Cook without stirring until the sugar transforms into a caramel color.

Pour in cream – it will bubble slightly. Cook for about 1 minute, stirring constantly until smooth. Remove from heat and add vanilla extract, butter and salt. Stir until it’s smooth and then transfer it into a bowl to cool.

Dissolve gelatin in cold water and let it swell for 5 to 10 minutes. Gently heat the gelatin until it dissolves and then mix it into the caramel sauce.

Whip the remaining 1 1/2 cups (360g) of whipping cream until soft peaks form. Add the caramel mixture and mix until well combined.

Assemble the cake

Place a cake ring around the cake and line it with an acetate sheet.

Pour the caramel mousse on top of the cake. Use an offset spatula to smooth out the top.

Cover the cake and refrigerate it for 4-6 hours or overnight to allow it to set.

Finally, decorate the cake with cinnamon whipped cream, blueberries, caramel pecan shards, and a sprinkle of cinnamon powder.
