Easy recipe for Peanut & chocolate marble cake (Pascal Hainigue)

Peanut & chocolate marble cake (Pascal Hainigue)

The is already quite a few recipes of marble cakes on my blog, but when I saw this one in the last issue of Fou de Pâtisserie, I couldn't resist ! This time it’s a chocolate and peanut marble cake, with peanut and chocolate glaze, caramelized peanuts and caramel pieces. These last two elements are completely optional, you can very well just make the cake and its frosting, you will save time if you are in a hurry, and you will already have a delicious and very beautiful cake ! The proportions indicated for the peanut praline and for the caramel are too large, but these are difficult preparations to make in small quantities; the praliné can be kept very well for several weeks or even months, and the caramel can also be kept in the refrigerator for several days and can be eaten with pancakes, yogurts, etc.

Prep time : 1 hour ((40 minutes if you just prepare the cake with glaze) + 1h10 cooking + time for the cake to cool down before glazing
For a 20cm cake :

Peanut praliné :

150g sugar

200g peanuts

Roast the peanuts in the preheated oven at 150°C for about 20 minutes (you can roast the peanuts for the caramelized peanuts for decoration and those for the glaze at the same time); the peanuts should be golden and very fragrant when removed from the oven.

With the sugar, make a caramel. Pour it over the peanuts, allow to cool completely then mix until you have a praliné.

Cacao batter :

60g butter

110g sugar

15g cocoa powder without sugar

51g egg (1 egg)

1.5g salt

93g cream 35% fat

100g flour

2.5g baking powder

Mix the softened butter with the sugar and salt with a spatula .

Add the egg, then the flour, cocoa and yeast previously mixed and sieved.

Finish by adding the cream.

Peanut batter :

60g butter

110g sugar

50g peanut praliné

50g egg (1egg)

1.5g salt

90g cream 35% fat

95g flour

2.5g baking powder

Mix the softened butter with the praliné, sugar and salt with a spatula.

Add the egg, then the flour and the yeast previously sifted and mixed.

Finish by adding the cream.

Cooking :

Alternate the two batters in the buttered or lined with parchment paper cake pan.

Pipe a thin line of butter in the center of the cake.

Bake for 1 hour and 10 minutes in the oven preheated to 165°C. When the cake is baked, unmold it and let it cool on a wire rack. You can put it in the freezer before glazing it, I didn’t and the glazing held up well anyway!

Caramel :

50g cream 35% fat

25g glucose

100g sugar

1.5g salt

75g butter

Make a caramel with the sugar end glucose.

Separately, heat the cream.

Pour the hot cream on the caramel, stirring well, then add the salt and cook until it reaches a temperature of 138°C.

Add the butter cut into small pieces, then pour onto a baking sheet covered with a silpat or parchment paper. Let cool.

Caramelized peanuts :

40g peanuts

7g sugar

2ml of water (20g)

2ml peanut oil (20g)

Roast the peanuts if you haven't done it at the same time as for the praliné.

Make a syrup with water and sugar, and bake it up to 120°C. Pour the peanuts into the syrup, then continue to cook, stirring until the peanuts are nicely caramelized.
