Not So Praline – Chocolate Mousse Cake

Several months ago Alicia asked if I can make a cake with crunchy base. She emphasized on the base as she likes the crunch, but she was unable to tell me what was that exactly until we had our high tea at a 5-star hotel.  She had this slice of cake that has crunchy base top with mouse and chocolate cake, and coated with chocolate ganache.  I confidently told her that the base was praline feuilletine.  At the back of my mind, I decided to make this for her birthday despite the risk of failure. You can buy praline paste off the shelf but I wanted to give it a try by making. Due to lack of knowledge and inappropriate use of blender (best to use food processor), mine remained as crumbs after processing for 15mins. As there wasn’t any sign of the crumbs turning into paste, I raised my white flag and went ahead to mix butter and cornflakes ( substitution of feuilletine) into the praline crumbs. It looks like this after being pressed onto the cake tin.

I googled to figure out my mistake and here is the link from Joe Pastry.   In his illustration, you will find it normal to get crumbs at the start  and with further process the oil will leak out of the chopped nuts and begin to create a more butter-like texture.  Joe has shared a tip is to add oil if you encounter difficulty in breaking down the praline. 

I hope birthday girl does not mind this NOT so praline Chocolate Mousse Cake.

Happy Birthday to YOU!

I am not ready with the recipe at this time as it was a mix & match from all over.  I will share the recipe once sorted.  Akan datang…

Not So Praline – Chocolate Mousse

Ingredients ( Base )

Praline Paste

70g feuilletine – (I used cornflakes)


Mix feuilletine / cornflakes with praline paste.  Press the mixture onto the base of a 8” square tin.

( As I did not achieve the correct consistency of praline paste, I added 60g melted butter into mixture ).

Praline Paste

70g hazelnut, lightly toasted

100g caster sugar

60g water ( can increase to 100g )


In a saucepan, bring sugar and water to boil.  Simmer without stiring for 10 minutes or until light golden in colour.  Remove from heat and quickly stir in the lightly toasted hazelnuts. Allow the caramel to cool on parchment paper. When cool, break up the praline and put the pieces in food processor. Pulse the food processor until the pieces begin to smooth until a paste. Continue to process until desired smoothness.

  1. BIG THANKS for the 99.9 marks cake! 100 marks for the taste, decorations (realized from your photo that the strawberries & marshmallows are actually not so ‘scattered’), mousse, chocolate and spongecake layers, 0.1 penalised for the praline base … Haha ^o^ looking forward to chocolate praline cake version 2.0.
