Step-by-Step Instructions
- Preheat your oven to 350°F (175°C) and prepare three 8-inch round cake pans by greasing them and lining with parchment paper.
- Make the blackberry purée by simmering fresh blackberries in a saucepan until soft, then mash and strain through a sieve.
- In a mixing bowl, whisk together flour, cocoa powder, baking soda, baking powder, and salt.
- In another bowl, blend sugar, oil, and eggs until smooth, then add buttermilk, blackberry purée, and vanilla.
- Gradually fold in the dry ingredients and add food coloring if desired, then transfer batter to the prepared pans.
- Bake for 25-28 minutes until a toothpick comes out clean.
- Cool the cakes on wire racks for 10 minutes, then remove from pans and cool completely.
- Prepare the frosting by beating cream cheese and butter until smooth, then add powdered sugar and blackberry jam.
- Assemble the cake by layering three cake layers with frosting in between.
- Make the glaze by combining blackberry jam, water, and lemon juice over low heat until smooth.
- Garnish with fresh blackberries and optionally with edible violets or petals.

Notes
For best results, do not overmix the batter and ensure cakes are completely cool before frosting.
