How To Make This Chocolate Fudge Cake
Step 1: Preheat Oven and Prepare Vegan Buttermilk
Preheat the oven to 355 ̊F (180 ̊C) and line an 8-inch (20-cm) loose-bottom cake pan with parchment paper.
To make the vegan buttermilk alternative, add the apple cider vinegar to the soy milk, stir, and let it thicken for 5 minutes.
Step 2: Prepare the Chocolate Batter and Bake
Next, in a large mixing bowl, combine the sugar and olive oil and, using a wooden spoon, mix until pale and fluffy. Add the buttermilk and yogurt, stirring to combine.
Sift the cocoa powder, flour, baking powder, baking soda and a generous pinch of salt into the bowl with the wet ingredients. Fold the ingredients and, using a wooden spoon, mix well until you’re left with a smooth, chocolaty mixture.
Pour the batter into the cake pan and bake for 30 minutes.
Step 3: Prepare the Decadent Chocolate Frosting
Meanwhile, to make the frosting, start by beating the butter until pale and fluffy, using either a stand mixer or an electric hand mixer. Gradually add the powdered sugar and cocoa powder and continue to mix until fully incorporated.
Gently melt the chocolate, then drizzle it into your frosting while gently whipping until fully incorporated.
Step 4: Decorate the Chocolate Fudge Cake
Once your cake has cooled, spread the creamy chocolate frosting over the cake. Arrange the strawberries and raspberries around the edge of the cake to decorate along with the pomegranate seeds and chopped chocolate pieces.
