Instructions
 

  • Step 1: Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
  • Step 2: Mash 1 1/2 cups fresh blackberries with a fork until juicy but slightly chunky.
  • Step 3: In a medium bowl, whisk together all-purpose flour, baking powder, baking soda, and salt.
  • Step 4: In a large bowl, beat butter and granulated sugar until light and fluffy, about 3-5 minutes.
  • Step 5: Add eggs one at a time, beating well after each addition.
  • Step 6: Mix in vanilla extract, lemon zest (if using), and purple food coloring (optional).
  • Step 7: Alternately add dry ingredients and buttermilk to butter mixture, starting and ending with dry ingredients. Mix just until combined.
  • Step 8: Gently fold mashed blackberries into batter, careful not to overmix.
  • Step 9: Divide batter evenly between prepared pans and smooth tops. Bake 30–35 minutes until toothpick comes out clean.
  • Step 10: Let cakes cool in pans 10 minutes, then transfer to wire racks to cool completely before frosting.
  • Step 11: Place 1 cup fresh blackberries in a small saucepan over low heat. Cook until thick puree forms, about 10 minutes. Strain seeds and cool completely.
  • Step 12: In a large bowl, beat butter and cream cheese until smooth and creamy.
  • Step 13: Gradually add powdered sugar, beating well after each addition.
  • Step 14: Mix in cooled blackberry puree, vanilla extract, and a pinch of salt. Beat until smooth and spreadable.
  • Step 15: Place one cake layer on serving plate. Spread a generous layer of frosting evenly over the top.
  • Step 16: Place second cake layer on top, frost entire cake with remaining frosting for smooth finish.
  • Step 17: Decorate with fresh blackberries, edible flowers, and mint leaves if desired.

Notes

Store cake covered loosely in fridge to keep frosting fresh and blackberries vibrant. Let slices sit at room temp up to 2 hours before serving. Cake best eaten within 3-4 days. Freeze unfrosted layers wrapped tightly up to 2 months; thaw fully before frosting.
