Salted Caramel Chocolate Fudge Cake

For my gorgeous girls birthday I let her pick a cake for me to create and of course it had chocolate and caramel in it! It was a day of baking 3 mini cake layers (separately), making the richest caramel butter cream (which is amazing) and the chocolatiest fudge frosting I have ever tasted! Needless to say the cake was delicious and I am so thankful I only made a baby cake as it was super rich and decadent.

3-layer cake

Chocolate Fudge Cake (I used Donna Hays Chocolate Cake)
Ingredients
200g butter, chopped
200g dark chocolate, chopped
30ml water
3 eggs
220g caster sugar
¾ cup self-raising flour, sifted
¼ cup cocoa, sifted

Method
- Oven to 160°
- Place butter, chocolate, vanilla and water in saucepan over a low heat and stir until melted and smooth
- Allow to cool
- Place the eggs and sugar in the bowl of an electric mixer and beat for 6 mins or until pale and thick
- Add the chocolate mixture and beat until combined
- Fold through flour and cocoa, don’t over stir though
- Split the mixture into 3 bowls, pour the first one into a lightly greased 22cm spring form tin and bake for about 45-60 mins (keep checking)
- Repeat this with the other 2 batches of the cake so that you have 3 even cooked layers
- Set aside to cool

Salted Caramel Swiss Buttercream (for the filling)
Ingredients
200g sugar
60 ml water
60ml heavy cream
generous pinch of sea salt 1 1/2 cups (340 g/12 oz) unsalted butter, at room temperature
4 large egg whites (120 g)
1 teaspoon pure vanilla extract

Method
- Place 130 grams of the sugar and the water in a medium saucepan to a boil over medium heat. 
- Brush down the sides of the pot with a dampened pastry brush to prevent sugar crystals from forming. Stop stirring and cook until caramel is dark amber, gently swirling from time to time. 
- Remove from heat, and slowly add cream, whisking by hand until smooth. It will be splatter, so be careful. Whisk in sea salt and vanilla. Let cool.
- Place butter in an electric mixer fitted with the flat beater attachment and beat on medium speed until pale and fluffy, about 3-5 minutes. Transfer to a large bowl and set aside.
- Wipe the bowl of an electric mixer clean with lemon juice, and place egg whites and remaining sugar into bowl over a pot of simmering water (not boiling–you don’t want to cook the eggs). Whisk occasionally and gently until sugar dissolves and mixture registers 160° on a candy thermometer.
- Remove the bowl from heat, and place back onto the mixer fitted with the whisk attachment. Whisk on medium speed for 5 minutes. Increase speed to medium-high, and whisk until stiff, glossy peaks form (about 5-6 minutes). Once the bottom of the bowl is neutral and no longer warm to the touch, reduce speed to medium-low, and add beaten butter, one cup at a time, whisking well after each addition.
- Switch to paddle attachment. With mixer on low speed, add cooled caramel and beat until smooth (about 3-5 minutes).

Dark Chocolate Fudge Frosting
(This makes a fair bit)

Ingredients
45g cocoa powder
90ml boiling water
340g unsalted butter, room temperature
63g icing sugar
pinch of salt
454 good-quality dark chocolate, melted and cooled

Method
- Combine cocoa powder and the boiling water in a small bowl or glass measuring cup, and stir until it cocoa has dissolved.
- In an electric mixer fitted with the flat beater attachment, beat the butter, the icing sugar, and salt on medium-high speed until it is pale and fluffy–about 5 minutes.
- Reduce mixer speed to low, and add melted chocolate (cooled), beating until combined and scraping down the sides of the bowl as needed.
- Beat in the cocoa mixture until well incorporated.

Notes:
Frosting can be refrigerated for up to 5 days, or frozen for up to 1 month in an airtight container.

Assembly of the Sweet & Salty Cake
- Trim any doming from the tops of your cake layers with a sharp, serrated knife and place first layer, face up, on your cake board, pedestal, or plate.
- Using a small offset palette knife, spread approximately 3/4 cup of the caramel buttercream evenly on the top.
- Repeat this 1-2 until you come to the final layer, which you will place face down on the top of the cake.
- Place cake on a turntable (if possible), and using a small offset palette knife for the top of the cake, and medium straight palette knife for the sides, cover the cake in a thin layer of chocolate frosting (or chocolate butter cream, if using) to mask (seal in crumbs).                
- Refrigerate for 30 minutes (or more). *This does not need to be perfect, as that will come with the top “coat” of butter cream.
- Once the icing has cooled, ice again over the top, using a palette knife and a glass of warm water to get a smooth clean finish.
- You can keep it in the fridge but keep it out for 2 hours before serving so the butter cream has softened.
- Sprinkle with salt
- Use a sharp heated knife to cut the cake, cleaning it every cut to get a nice clean finish
