Almost everyone is crazy about chocolate, especially when it comes to blowing out the candles on a birthday cake with sponge cake and truffle. Surely more than one person’s mouth is watering just thinking about it. With this recipe explained step by step we can surprise our guests.
Making a birthday cake is always a big challenge, especially if the person we want to surprise is someone close to us. We tend to think that it is easier to buy the cake than to make it at home, but with this recipe we can surprise without complicating our lives.
It is a hearty cake but super juicy and full of flavour. We can also make two versions: for adults and for children (adding or not some liquor). The important thing is to prepare the preparations in time to assemble it at the last minute and make it look really nice. It will not last long because they will surely eat it in a flash, that is guaranteed. The sponge and truffle birthday cake will become the favourite at celebrations when it is time to blow out the candles.
Ingredients
For the truffle filling
- 1000 g whipping cream
- 80 g icing sugar
- 200 g of dessert chocolate
For the cake
- 100 g sunflower oil
- 100 g white sugar
- 2 large eggs
- 2 tablespoons whole milk
- 1 unsweetened natural yogurt (125 g)
- 1 teaspoon vanilla essence
- 180 g of pastry flour
- 40 g of 100% pure cocoa powder (VALUE)
- 1 sachet of chemical booster (Royal)
- 1 pinch of salt
- Liquor (optional)
Instructions
- To make the sponge and truffle birthday cake, you need to do two things. We start by preparing the truffle that we will use to fill and cover our birthday cake. In a saucepan, heat the 500 ml of cream together with the 80 g of icing sugar until it reaches 90 ºC and keep it there. We don’t want it to boil (important).
- Heat the milk with the icing sugar to make the ganache for the birthday cake truffle. Once the cream and sugar are heated, add the chocolate to the saucepan and stir continuously over low heat until the chocolate is perfectly integrated. Let it cool and store in the refrigerator for at least 12 hours. This preparation must be very cold because we will later take it out and assemble it to make the truffle with which we will fill and decorate the birthday cake. That is why it is advisable to make this preparation the day before.
- Chill ganache to make birthday cake truffle.The next day,prepare the second part of this cake, which is the sponge cake, and finish making the truffle while the sponge cake cools down before assembling the cake. Preheat the oven to 160 ºC with heat from above and below.
- In a large bowl, add the 100 ml of sunflower oil, the 100 g of white sugar and the 2 eggs. Beat everything until well mixed.
- Mix eggs, sugar and oil for the chocolate sponge cake batter
- Add the 2 tablespoons of whole milk, the sugar-free natural yogurt and the vanilla essence to the mixture. Blend again to ensure that the ingredients are perfectly mixed.
- Mix yogurt, vanilla and milk for the birthday cake batter
- Finally,finish making the cake batter by adding the 180 g of baking flour, the 40 g of pure cocoa powder, the sachet of baking powder and the pinch of salt. We will sift everything together so that no lumps form when mixing.
- Add the flour, cocoa, baking powder and salt to mix the cake batter.Fill the mould (previously greased and lined the base with baking paper) and put it in the oven at 160ºC with heat from above and below for 1 hour.
- When you take it out, check that it is perfectly cooked by poking it with a toothpick. If it comes out clean, it is perfect. Wait a little while to unmold it and cool it on a rack. Set it aside until you are ready to assemble the cake.
- It’s time to assemble the truffle we prepared the day before. Put some very cold whipping cream in a bowl and whip it. Add some of the ganache and mix with a whisk or a hand mixer if you have one until it is perfectly integrated and has a consistency suitable for filling the cake and decorating the outside.
- Cut the cake into three parts from the base and fill the layers from the base with the truffle. As we fill the layers of cake with the truffle we can soak the cake a little with some liquor beforehand (as long as children are not going to eat it).Put the second layer of cake on and repeat the action.
- To finish, place the third layer of cake and cover the top and sides of the cake with truffle. It doesn’t have to be perfect.
- Decorate the cake with chocolate shavings, part of the ganache and some chocolate chips, for example. We make the shavings by grating one or two bars of the same chocolate that we used to make the ganache.
- Put the candles on the cake and serve.
