How to Make Chocolate Fudge Loaf Cake
Step 1: Preheat the Oven and Prepare the Tin
Preheat your oven to 180°C (160°C fan) / 350°F. Line a 9×5-inch (23x13cm) loaf tin with non-stick baking paper.
Step 2: Cream the Butter and Sugar
In a large mixing bowl, beat the softened butter with an electric whisk until creamy.
Add the sugar and whisk until the mixture is light and fluffy.
Step 3: Add the Eggs and Buttermilk
Whisk in the eggs, one at a time, making sure each one is fully incorporated before adding the next.
In a small mug, dissolve the instant coffee in 1 tbsp of hot water, then mix it into the buttermilk. Pour this into the cake batter and whisk until combined.
Step 4: Sift in the Dry Ingredients
Sift in the plain flour, cocoa powder, baking powder, and salt.
Using a spatula or wooden spoon, fold the dry ingredients into the wet ingredients until just combined.
Step 5: Bake the Cake
Scoop the batter into the prepared loaf tin and smooth the top evenly.
Bake in the preheated oven for 50–60 minutes, or until a toothpick inserted into the centre comes out with a few moist crumbs.
Let the cake cool completely in the tin before adding the icing.
How to Make the Fudgy Icing
Step 6: Melt the Icing Ingredients
In a medium saucepan, heat the butter, dark chocolate, double cream, icing sugar, and salt over low heat, stirring constantly until smooth.
Step 7: Chill the Icing
Pour the melted icing into a mixing bowl and let it cool to room temperature.
Cover with cling film and refrigerate for at least 1 hour, or until the icing is thick but still spreadable.
How to Decorate the Cake
Step 8: Make the Chocolate Drip
Take 3 tablespoons of the icing and place it in a microwave-safe bowl. Heat until melted and smooth.
Transfer to a piping bag fitted with a small round nozzle (or snip a small hole in a piping bag).
Slowly pipe drips around the edge of the cake, applying more pressure for longer drips and less for shorter ones.
Step 9: Add the Icing
Smooth the remaining chilled icing over the cake using a palette knife or the back of a spoon.
Slice and serve!

Tips for the Best Chocolate Fudge Loaf Cake
- Use Room Temperature Ingredients: This ensures even mixing and a smooth batter.
- Don’t Overmix: Overmixing can make the cake dense—fold gently until just combined.
- Cool the Cake Before Icing: Warm cake will melt the icing and cause it to slide off.
- Chill the Icing Before Spreading: This helps create a thick, spreadable consistency.
- Use Good-Quality Chocolate: High-quality dark chocolate makes a smoother, richer icing.
Serving Suggestions
This fudge loaf cake is delicious on its own, but here are a few ways to enhance it:
- With Fresh Berries: Raspberries or strawberries balance the richness.
- With a Drizzle of Extra Melted Chocolate: For even more indulgence.
- Serve it slightly warmed with some cream
Storage Tips

Instructions
For the cake

- In a small mug, dissolve the instant coffee in 1 teaspoon of hot water, stirring until no coffee granules remain, then mix it with the buttermilk until fully combined and pour it into the mix

- Scoop the mix into your prepared loaf tin and smooth it out evenly
- Bake in the oven for 50-60 minutes or until a toothpick inserted into the centre comes out clean. Let the cake cool fully before making the icing
For the icing
- Place all the ingredients for the icing in a medium saucepan and melt on a low heat, stirring constantly until the butter and chocolate have melted and everything is fully combined
- Pour the mix into a medium mixing bowl and let it cool to room temperature, then cover it with cling film and refrigerate for at least 1 hour. The icing should thicken to a firm, yet spreadable consistency
For the drip
- Take out about 3 tablespoons of the icing and place it in a microwave-safe bowl or ramekin. Microwave this on a medium heat until melted and smooth
- Place the melted icing in a piping bag fitted with a small round nozzle or cut a hole in the piping bag about 2mm wide

Add the icing
- Smooth the remaining chilled icing over the cake using a palette knife, the back of a spoon or you could always pipe it on. The choice is yours - Now it's ready to serve. Enjoy!
Notes
- Store in an airtight container in the fridge for up to 4 days. (This cake needs to be stored in the fridge because the icing contains double cream - Feel free to bring is back to room temperature before eating if you prefer)
- You can use heavy cream in place of double cream for the icing
- The icing may need longer than 1 hour in the fridge to reach your desired consistency. If it's too stiff to spread, let it sit at room temperature until it becomes spreadable again
- Oh and you can't taste the coffee, I promise!








Is double cream also called heavy cream?
I just read further down in your comments that it is the same thing.
