- Cream butter and sugar until pale and fluffy. Add eggs one at a time, then vanilla and blackberry puree.
- In a separate bowl, mix flour, cocoa, and baking soda. Fold dry ingredients into the wet mix alternately with yogurt.
- Divide batter into pans and bake at 350°F (175°C) for 30–35 minutes. Let cool completely.
- Whip mascarpone, cream, powdered sugar, and vanilla until soft peaks form. Swirl in blackberry jam if using.
- Layer cakes with cream filling and fresh blackberries. Frost with black cocoa buttercream.
- Decorate with fresh berries, black glitter, and optional edible flowers. Chill before serving.
Notes
Use activated charcoal or dark cocoa for color depth. Chill for clean slicing. Decorate just before serving for best freshness.
