For the pancakes:
- 140g plain flour
- 200ml whole milk
- 2 eggs
- 25g unsalted butter, melted, plus a little extra for greasing sunflower oil, for greasing
For the praline:
- 100g caster sugar
- 100g blanched almonds ½ tsp sea salt flakes
For the chocolate sauce:
- 250g dark chocolate finely chopped
- 50g unsalted butter
- 175ml whole milk
- 125ml double cream
- 2 tbsp brandy or dark rum
- 50g light muscovado sugar whipped cream, to serve
First make the pancakes. Sift the flour with a pinch of salt into a medium-size bowl and make a well in the middle. Mix the milk and 100ml of water together. Break the eggs into the well and start whisking slowly. Add the milk and water in a steady stream, whisking constantly and gradually incorporating the flour as you do so.
Whisk until the batter is smooth and all the flour has been incorporated. Set the batter aside to rest for 30 mins, then whisk the melted butter into the batter.
Heat the pan over a medium heat. Very lightly grease the pan with melted butter. Make the pancakes using about 2tbsp per pancake.
Lightly brush a baking sheet with sunflower oil. Tip the caster sugar into a medium-size saucepan, add 2-3 tbsp of water and set the pan over a low-medium heat to allow the sugar to slowly dissolve into the water. Bring to the boil and continue to cook until the syrup becomes amber-coloured caramel.
Working quickly, tip the blanched almonds and salt into the pan and continue to cook for 30 secs-1 min until the caramel turns deep amber and the almonds are toasted. Tip the praline onto the oiled baking sheet and leave until completely cold and hardened. Break the praline into chunks and whizz in the food processor until coarsely chopped.
To make the chocolate sauce, combine all the ingredients in a heatproof bowl set over a pan of barely simmering water. Stir occasionally until smooth and silky. Remove from the heat and cool to room temperature.
Heat oven to 180C/160C fan/gas 4. Lay one pancake in the bottom of a 20cm springform tin and spread over 1 tbsp of chocolate sauce. Scatter with chopped praline and top with another pancake. Continue in this manner until you have used all 12 pancakes, topping the stack with a pancake.
Cover the tin with foil and bake on the middle shelf of the oven for around 20 mins or until hot through. Gently warm the remaining chocolate sauce, cut the cake into wedges and serve scattered with the remaining praline chocolate sauce, and a bowl of lightly whipped cream alongside.
