Decadent Chocolate Slices with Chocolate Hazelnut Buttercream Frosting
These stunning chocolate slices would not look out of place in any french patisserie or fine dining restaurant yet are surprisingly simple to make – oh and did i mention they are totally delicious!!!
Ingredients
For the chocolate cake:
- 230 gr plain flour
- 400 gr caster sugar
- 85 gr cocoa powder sifted
- 2¼ tsp baking soda
- ½ tsp baking powder
- 1 tsp salt
- 240 ml whole milk
- 1½ tsp Nielsen Massey Pure Vanilla Extract
- 2 large room temperature eggs
- 150 ml hot water
For the chocolate hazelnut buttercream frosting:
- 230 gr unsalted butter
- 460 gr powdered sugar sifted
- 230 gr nutella
- 80 ml heavy cream
- 1 tsp vanilla extract
Instructions
- Preheat the oven to 350f and grease and line a large baking sheet with parchment paper. I used a 9¨ x 13¨
- In a large bowl whisk together the flour, sugar, cocoa powder, baking soda, baking powder and salt.
- In a separate bowl whisk together the vegetable oil, milk, vanilla and eggs then add these into the dry ingredients and mix until combined with a spatula.
- Add in the hot water and whisk until you have a smooth mixture.
- Pour onto the baking sheet and place in the oven for around 30 minutes until a toothpick comes out clean when inserted in the centre.
- Allow to cool completed before cutting and assembling.
To make the frosting:
- Beat the butter in a stand mixer for around two minutes until soft and smooth
- Add the powdered sugar, vanilla extract, cream and nutella and beat on medium for around two minutes until smooth
- If the frosting is too thick add a little more cream and if not thick enough add a little more powdered sugar until you have the perfect consistency
- Place the frosting into a large piping bag with a long petal nozzle fitted
(this frosting will keep in the fridge for one week)
- Once the cake has cooled completely, slice into slices approximately 1.5” x 5”
- Pipe the frosting across the top of each slice in a zigzag motion
- I like to top these with a chocolate heart or decoration so be creative
