Add your caramel to a small piping bag and heat in the microwave for 10 seconds to soften. Leave to one side.
Place your first cake on your serving plate and spread the buttercream on top. Smooth using a spatula, don’t worry is any of the buttercream splodges out the side. Drizzle over the caramel. Repeat until your cake is stacked.
Smooth the buttercream around the sides of the cake and into any gaps. Smooth using a cake smoother. Don't worry if you can still see the cake through the buttercream this is just our crumb coat.
Pop the cake into the fridge for 30 minutes or so until the buttercream has set.
Once the buttercream has set remove the cake from the fridge and spread the remaining buttercream onto the top of the cake. Using a palette knife smooth the buttercream onto the top of the cake and around the sides.
Using your smoother, smooth around the sides, if there are any gaps fill these with the buttercream and continue to smooth around the sides until the cake is smooth. You will most likely take some of the buttercream off the cake if you do pop this back into your bowl.
Smooth the top of your cake using your angled palette knife.
Put the cake back into the fridge for 30 minutes for the buttercream to set.
Any left over buttercream pop this into a piping bag and leave to one side.
Once the buttercream has set remove the cake and chocolate ganache from the fridge. Using a small palette knife, get a little of the ganache on the end of your palette knife and smooth this onto the bottom of the cake.
Work your way around the entire cake using small amounts of ganache at a time.
Now get your cake smoother and smooth the ganache, just like you do for buttercream, if there is any excess ganache pop this back into the bowl
Any leftover ganache spread this onto the top of the cake.
Put the cake back into the fridge for 20-30 minutes or until the chocolate ganache has set.
