Ingredients

Cake:

  • 200g (¾ cup + 2 tbsp) butter
  • 200g (7 oz) dark chocolate
  • 100ml brewed coffee (or water)
  • 3 eggs
  • 120g (½ cup + 1 tbsp) brown sugar
  • 120g (½ cup + 1 tbsp) white sugar
  • 1 teaspoon vanilla essence
  • 80g (⅔ cup) spelt flour (see note 1)
  • 30g (¼ cup) cocoa

Topping:

  • 200ml (⅘ cup) whipping cream
  • 85g (¼ cup + 2 tbsp) sugar
  • 100ml (¼ cup + 3 tbsp) syrup (any kind, light or dark)
  • 100g (3½ oz) dark chocolate
  • 100g (¼ cup + 3 tbsp) butter
  • berries to decorate (optional)

Instructions

Kladdkaka:

  • Pre-heat the oven to 175°C / 350℉.
  • Grease a 9 inch (24cm) tin spring-form tin (you can use a smaller one but you will need to adjust the baking times).
  • Add the butter and chocolate to a pan and slowly heat until just melted.
  • Add the coffee (or water) and stir to combine. Leave the mixture to cool for a short while.
  • In a bowl, whisk the eggs and sugars together.
  • Pour in the chocolate mixture and stir until everything is combined.
  • Add the flour, cocoa and vanilla sugar and once more, stir, just until everything is well incorporated.
  • Pour into the prepared pan. Bake between 15-25 minutes (see note 2).
  • When ready, remove from the oven and allow to cool completely (keep it in the springform).

Fudge Topping:

  • Mix all of the ingredients apart from the butter, in a pan.
  • Let the mixture cook until it starts to thicken (around 15 minutes).
  • Remove the pan from the heat and beat in the butter until a nice fudgy texture is achieved.
  • Allow the mixture to cool (and thicken for a while) before pouring over the cake.
  • Allow to set completely (I usually leave it in the fridge overnight).
  • When ready to eat, slice using a hot knife. If you want a gooey, soft fudgy topping, don't keep the cake in the fridge. Serves with fresh berries, or whatever else you fancy. Enjoy!

Notes

 
  1. You can substitute spelt flour for the same amount of regular flour.
  2. The baking times depends on how runny you want your cake. As a rough idea: baking for 15 minutes will produce a very molten, runny centre. 25 minutes will give you a firm, brownie-like texture.

I have converted grams to cups/ounces/tablespoons using online converters. Although I have no reason to believe they are inaccurate, please be aware that I have not made the recipe with imperial measurements.
In addition, many ingredients are different in Europe compared to North America. I do all I can to offer possible alternatives and to ensure the best possible outcomes for everyone. However, results cannot always be guaranteed if you have not used the same ingredients, measurements or methods as me.
