For the Salted Caramel Sauce

  • 150g Soft Light Brown Sugar
  • 2 tbsp Golden Syrup
  • 250ml Double Cream
  • 50g Butter
  • ½ tsp Flaky Sea Salt

Essential Kit

  • A deep-sided baking tin, 20 x 25cm
  • An electric hand-held mixer

Step-by-Step Instructions

1. Prepare the Baking Tin & Preheat Oven

Preheat your oven to 180°C/160°C fan/gas 4. Grease a deep-sided baking tin (20 x 25cm) and line it with baking parchment.

2. Cream Butter and Sugars

In a large bowl, using an electric hand-held mixer, beat the softened butter and both caster and soft light brown sugars together until the mixture is light and fluffy.

3. Add Eggs

Gradually add the eggs, beating well after each addition until fully incorporated.

4. Sift Dry Ingredients & Combine

Sift the self-raising flour, baking powder, cocoa powder, and a pinch of salt over the wet mixture. Beat until all ingredients are well combined. Add the milk and stir gently.

5. Fold in Chocolate Chips

Fold in the dark chocolate chips (and cacao nibs, if using) into the batter until evenly distributed.

6. Bake the Sponge

Pour the batter into the prepared baking tin and level out the top with the back of a spoon or a spatula. Sprinkle over the cacao nibs (if using). Bake for 40 minutes, or until a skewer inserted into the centre comes out clean. Leave to cool slightly in the tin.

7. Make the Salted Caramel Sauce

While the sponge is baking or cooling, prepare the sauce. Place all the ingredients for the salted caramel sauce (soft light brown sugar, golden syrup, double cream, butter, and flaky sea salt) in a small saucepan over a low to medium heat. Gently bring the mixture to a boil, stirring constantly until the sugar has completely dissolved. Boil for 2 minutes, then remove from the heat and leave to stand for 5 minutes before serving.

8. Serve

Once slightly cooled, cut the chocolate sponge into 9 squares. Serve warm with a generous drizzle of the homemade salted caramel sauce and a scoop of vanilla ice cream, if desired.

Notes

Room temperature ingredients ensure a smoother batter and better rise. Don’t overmix the batter to avoid a tough sponge. Quality cocoa powder is key for a rich chocolate flavour.
