Delicious Hot Chocolate Cake

This cocoa Cake may be a moist cake, cocoa buttercream frosting and marshmallow filling! The mixture is wonderfully decadent and addicting!

So this cocoa Cake has been on my mind for a few time. It had been on my calendar for the vacations and just kept getting bumped back until I finally got around thereto after the vacations passed. cocoa just feels very holiday-y to me, but it’s obviously perfect for any weather .

Delicious Hot Chocolate Cake

And I’m an enormous cocoa fan. Have you ever ever tried it with Baileys in it? It’s amazing. And therefore the more marshmallows the higher. As I used to be saying to the twins yesterday (and getting some fabulous laughs with),If only you'll actually hear me say that. 

The only thing that would make this cake better may be a wonderful marshmallow filling. I used a marshmallow frosting made with just three ingredients – butter, granulated sugar and marshmallow cream.

 INGREDIENTS :

CHOCOLATE CAKE :

• 2 cups (260g) flour
• 2 cups (414g) sugar
• 3/4 cup (85g) natural unsweetened cocoa powder
• 2 tsp baking soda
• 1 tsp salt
• 2 large eggs
• 1 cup (240ml) milk
• 1 cup (240ml) vegetable oil
• 1 1/2 tsp vanilla
• 1 cup (240ml)

HOT CHOCOLATE BUTTERCREAM FROSTING

• 4 tbsp (60ml) hot water/milk
• 2.92 oz hot chocolate powder mix
• 1 1/2 cups (336g) unsalted butter, room temperature
• 1 1/4 cup (237g) shortening
• 10 cups (1150g) powdered sugar
• 2 tbsp (14g) natural unsweetened cocoa powder
• 1–2 tbsp water or milk

MARSHMALLOW FILLING :

• 1/2 cup (112g) unsalted butter, room temperature
• 1 cup (115g) powdered sugar
• 10 oz marshmallow creme

WHITE CHOCOLATE GANACHE :

• 6 oz (1 cup) white chocolate chips
• 3 tbsp (45ml) heavy whipping cream
• Mini marshmallows
• Marshmallow bits

VANILLA BUTTERCREAM, OPTIONAL :

• 1/2 cup (112g) unsalted butter, room temperature
• 2 cups (230g) powdered sugar
• 1/2 tsp vanilla extract
• 1–2 tbsp water/milk

INSTRUCTIONS :

1. Prepare two 8 inch cake pans (see note below) with parchment paper circles in the bottom, and grease the sides. Preheat oven to 300°F (148°C).
2. To make the chocolate cake, add the dry ingredients to a large bowl and whisk together.
3. Add the eggs, milk, oil and vanilla extract to the dry ingredients and mix until well combined.
4. Add the hot water and mix until well combined.
5. Divide the batter evenly between the cakes pans and bake for 45-50 minutes, or until a toothpick comes out with a few crumbs.
6. Remove cakes from oven and allow to cool for 2-3 minutes, then remove to cooling racks to cool completely.
7. To make the hot chocolate frosting, dissolve the hot chocolate powder into the hot water or milk. It’ll be fairly thick. Set aside.
8. Add the butter and shortening to a large mixer bowl and beat until smooth.
9. Add about half of the powdered sugar and mix until well combined and smooth.
10. Add the hot chocolate mixture and cocoa powder and mix until well combined and smooth.
11. Add the remaining powdered sugar and mix until well combined and smooth.
12. Add additional water or milk as needed to get the right consistency.
13. To make the marshmallow filling, add the butter to a mixer bowl and beat until smooth.
14. Add the powdered sugar and beat until well combined and smooth. It’ll take a bit for it all to fully incorporate, so scrape down the sides of the bowl as needed and keep mixing.
15. Stir in the marshmallow cream. Set filling aside.
16. When you are ready to build the cake, remove cake domes from top with a large serrated knife, if needed. Divide each cake into two layers, so you have four total layers.
17. Place the first layer of cake on cake plate or cardboard cake circle. Add half a cup of hot chocolate frosting and spread into an even layer.
18. Pipe a dam around the outer edge of the cake, then fill it with about 3/4 cup of marshmallow filling. Spread into an even layer.
19. Place the second layer of cake on top and add another layer of hot chocolate frosting and marshmallow filling.
20. Repeat with the third layer of cake and filling, then top the cake with the final layer.
21. Spread a light crumb coat around the sides of the cake, then refrigerate for about an hour to let the filling firm up a bit. The layers will slip around a bit if you skip this step.
22. After refrigerating, frost the outside of the cake. Feel free to use my tutorial for frosting a smooth cake with buttercream.
23. To make the white chocolate ganache, add the white chocolate chips to a medium sized bowl. Heat the cream just until it begins to boil, then pour over the white chocolate.
24. Whisk the chocolate mixture so that it begins to melt. Heat for another 10 seconds and whisk to continue melting. If needed heat another 10 seconds.
25. Drizzle the white chocolate around the top edge of the cake. I like to use a squeeze bottle, but you can also use a spoon or any other method.
26. Fill in the top of the cake with the ganache and spread evenly.
27. To create the ring of marshmallows, make the vanilla buttercream. Add the butter to a mixer bowl and beat until smooth.
28. Add half of the powdered sugar and beat until smooth.
29. Add a tablespoon of water or milk and the vanilla extract and beat until smooth.
30. Add the remaining powdered sugar and beat until smooth. Add additional water or milk, if needed for the right consistency.
31. Pipe a ring of the vanilla buttercream around the top edge of the cake, then add mini marshmallows and marshmallow bits.
32. Refrigerate cake until ready to serve. Cake is best served after letting it sit out for a few hours to come closer to room temperature. Cake is best when stored well covered for 2-3 days.
