• 3 large eggs

• 1 tsp vanilla extract

• 200g (1⅔ cups) all-purpose flour

• 1 tsp baking powder

• ½ tsp salt

For the Caramel Filling:

• 400g (1 can) sweetened condensed milk

• 150g (¾ cup) brown sugar

• 100g (½ cup) unsalted butter

• 2 tbsp golden syrup or corn syrup

• ½ tsp salt

• 1 tsp vanilla extract

For the Chocolate Ganache Topping:

• 200g (7 oz) dark chocolate (at least 60% cocoa), chopped

• 150ml (⅔ cup) heavy cream

• 1 tbsp butter (optional, for shine)

Optional Garnish:

• Gold leaf or edible gold dust (for a luxurious touch)

• Shortbread cookie crumbs

Preparation Steps

Step 1: Prepare the Cake Base (Shortbread Sponge)

1. Preheat the oven to 175°C (350°F). Grease and line a 9-inch round cake pan or springform pan with parchment paper.

2. In a large bowl, cream the butter and sugar together until light and fluffy (about 3–4 minutes).

3. Add the eggs one at a time, beating well after each addition.

4. Mix in the vanilla extract.

5. In a separate bowl, sift together the flour, baking powder, and salt.

6. Gradually fold the dry ingredients into the wet mixture until just combined.

7. Pour the batter into the prepared cake pan and smooth the top.

8. Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean.

9. Remove from oven and allow to cool completely in the pan.

Step 2: Make the Caramel Filling

1. In a heavy-bottomed saucepan, combine butter, brown sugar, sweetened condensed milk, and syrup over medium-low heat.

2. Stir continuously to prevent burning. Bring to a gentle simmer and cook for about 10–12 minutes until the mixture thickens and darkens in color.

3. Remove from heat, stir in the salt and vanilla extract.

4. Let it cool slightly before pouring over the cooled cake base.

5. Use an offset spatula to spread the caramel evenly over the cake.

6. Refrigerate for at least 1 hour, or until caramel is set.

Step 3: Prepare the Chocolate Ganache

1. Place the chopped chocolate in a heatproof bowl.

2. Heat the cream in a small saucepan until it just starts to simmer (do not boil).

3. Pour the hot cream over the chocolate and let sit for 2–3 minutes.

4. Stir gently until the chocolate is melted and the ganache is smooth.

5. Stir in a bit of butter if you prefer a glossier finish.

6. Let the ganache cool slightly (not too much, or it will harden), then pour over the chilled caramel layer.

7. Tilt the pan to evenly distribute the ganache.

8. Optionally, sprinkle with flaky sea salt or gold dust for a luxurious finish.

9. Chill again for at least 1 hour to fully set.

Step 4: Serve and Enjoy

Once set, remove the cake from the pan carefully.
Use a sharp, warm knife (dipped in hot water and wiped dry) to slice cleanly through the layers.

Pro Tip: Serve with a dollop of whipped cream or vanilla ice cream for extra indulgence.

Recipe Intensity and Skill Level

Difficulty:
Intermediate — This recipe involves multiple components (cake, caramel, ganache) and requires attention to detail, especially when making the caramel. But don’t worry, each step is manageable with a bit of patience and preparation.

Time Commitment:
This is not a quick dessert, but it’s well worth the time. The cake can be made in stages ahead of time and assembled when ready to serve.

Storage and Make-Ahead Tips

• Store in an airtight container in the refrigerator for up to 5 days.

• You can freeze the cake without the ganache topping for up to 2 months. Thaw in the fridge overnight, add ganache before serving.

• Caramel can be made a day ahead and stored covered in the fridge.
