Chocolate cake with chocolate chip mascarpone filling and chocolate fudge frosting

Sponsored post.

Spring is nowhere to be seen, which also means there is no produce yet. Chocolate to the rescue! I don’t mind at all, although I do long to see the first rhubarb stalks at the market. Sooner than later, I hope. But for now, I have chocolate and that’s pretty great. This chocolatey beauty of a cake is perfect for anyone who loves chocolate as it’s super rich and moist, made with chocolate from Tales chocolate. The chocolate bar, “Gamla Stan” is created to tell a story of Stockholm’s Old Town with a sculptural map on the bar itself, but also through the flavour and taste experience. This is their first chocolate bar, and I can’t wait to see what they come up with next! They’re sold at selected Designtorget stores in Stockholm and they also have an online shop with worldwide shipping, in case you yourself would like a small piece of Stockholm!

I rarely buy 85% chocolate because I tend to think it’s too strong for me, but I was so wrong! This one is smooth and fruity,  perfect to eat as is, and also wonderful for baking. It looks good, it tastes good, and it’s also organic, fair trade and additive free. I mean, what more could one wish for? As for the cake, I had one piece the day I made it, and one piece the day after and I must say it keeps getting better and better. I gave the leftovers to my mom, and she’s been eating it for a few days now. She says it gets even better, especially with a little sprinkle of salt.

Chocolate cake with chocolate chip mascarpone filling and chocolate fudge frosting

Makes one 8-inch cake, serves 10-12

Ingredients

Chocolate cake

  • 200 g (~1 3/4 sticks) salted butter
  • 125 ml (1/2 cup) milk
  • 240 g (1 2/3 cups) all purpose flour
  • 1 1/2 tsp. baking soda
  • 68 g (2/3 cup) cocoa powder
  • 315 g (1 1/2 cups) granulated sugar
  • 1/4 tsp. flaky salt
  • 2 medium eggs
  • 150 ml (2/3 cup) sour cream
  • 125 ml (1/2 cup) hot coffee

Chocolate chip mascarpone filling

  • 250 g mascarpone
  • 2 tbsp. powdered sugar
  • 150 ml (2/3 cup) heavy cream
  • pinch of salt
  • 80 g (2.8 oz) dark chocolate (85%), finely chopped

Chocolate fudge frosting

  • 100 g (3.5 oz) dark chocolate (85%), chopped
  • 175 g (~1 1/2 sticks) salted butter, softened
  • 150 g (1 cup) powdered sugar
  • 4 tbsp. (1/4 cup) cocoa powder
  • 2-3 tbsp milk or heavy cream
  • 4 tbsp. (1/4 cup) sour cream (can be omitted, but tastes really nice with the chocolate)
  • flaky salt, to sprinkle

Instructions

Chocolate cake

  1. Preheat oven to 175°C (350°F). Butter two 20 cm (8-inch) cake pans and dust them with flour or cocoa powder.
  2. Melt the butter, add milk and set aside to cool.
  3. In a large bowl, mix together the flour, baking soda, cocoa powder, sugar and salt. Add the butter mixture, eggs and sour cream to the dry ingredients and beat until just smooth.
  4. Add the hot coffee and stir until smooth (batter will be quite liquid at this point).
  5. Divide the batter evenly between the two cake pans. Bake the cakes on the lowest rack for 22-26 minutes or until a cake tester comes out clean. Let the cakes cool in their pans for 10 minutes, then invert onto a cooling rack to cool completely.
  6. When cakes are completely cool, split them in half using a serrated knife.

Chocolate chip mascarpone filling

  1. In a medium bowl, beat mascarpone and powdered sugar until smooth and creamy. Add the cream and salt and beat until mixture thickens. Stir in the chopped chocolate.

Chocolate fudge frosting & assembly

  1. Melt the chocolate and set aside to cool.
  2. Beat butter, powdered sugar and cocoa powder until pale and creamy, about 2 minutes. Add the cooled, melted chocolate and beat until smooth. Add milk or heavy cream and sour cream and beat until incorporated. If frosting feels loose, put the bowl in the fridge for a few minutes.
  3. Place the first cake layer on a plate or cake stand. Spread with a layer of mascarpone filling. Repeat with remaining layers.
  4. Spread the chocolate frosting on the top and sides of the cake using an offset spatula. If you have chocolate frosting left over, feel free to pipe it on top of the cake. Sprinkle with flaky salt.

    • Aww thank you Bea, that means a lot! I know, aren’t they pretty?! And honestly the chocolate is amazing, and I tend to think 85 is way too dark.. but it totally works in this one! x

  5. Thank you for great pictures and beautiful cake. I have some questions:
    It’s not a biscuit dough, is it? and it’s not necessary to beat for a long time?
    I am from Russia and we have different types of sour cream – 10%, 15%, 20%, 30% – fat. What is good for this recipe?
    Thanks)

    • Hi Kris! There’s no biscuit dough in this recipe, no 🙂 I’m assuming you’re thinking about chocolate chip cookies?
      I’d say 10% or 15% is a good choice. Thank you for your comment!

Så fina bilder, jag blir verkligen inspirerad att ta såna här fina bilder på tårtan jag ska göra, lägger mig upp bilder på denna på min blogg och taggar dig! Tack för receptet!

    • Hej! 🙂 Sourcream är gräddfil och heavy cream är vispgrädde. Så fint att du ska baka den till din mamma 🙂 Ska bli så roligt att se resultatet!

    • Hi Faiza, sorry for the late reply! Thick yoghurt (greek or turkish style) would probably be your best option 🙂

  13. Hej

    Jag gjorde précis den här kakan, men den blev inte lika hög som på bilden. Det star baking powder I receptet, är det bikarbonat eller bakpulver?

    Reply

    • Hej Linda! Undra vad det kan vara… Det står baking soda i receptet, och det är bikarbonat. Använde du samma storlek på formen, dvs. 20 cm?

  14. Hej!
    Gjorde denna tårta för ett tag sedan, och den blev supergod! Tack för det.
    Tänkte upprepa succén, men en av gästerna är laktosintolerant. Kan man byta ut mascarpone osten mot något annat?

    Reply

    • Hej Sorana!
      Vad roligt att höra! 🙂 Tack för din kommentar! Du kan göra egen laktosfri mascarpone om du har tid och ork, jag har ett recept i min pajbok, men det finns även ett här: http://matmatmat.se/hemmagjord-mascarpone/
      Du skulle också kunna köpa laktosfri cream cheese. Det blir ju inte riktigt samma, något syrligare, men sannolikt jättegott ändå!
