Purple is passionate. It’s mystical. It’s regal. Don’t we all know someone whose favorite color is purple? It’s painfully obvious. They can’t hide it. They don’t want to hide it. They can’t just be friends with purple. They’re in a relationship with purple. The first time I made this Purple Berry Cake, a purple lover I know said that when she saw it, it spoke to her soul. 
Fresh berry purée is added to the batter, creating a soft, moist cake. The layers are brushed with berry syrup, which helps keeps the cake moist and gives it a nice punch of berry flavor.  I used blackberries and blueberries, but you can use any combination of purple berries that you like. After baking, the color of the cake layers will be a brownish gray with a hint of purple, depending on your berries. I think I need to come up with name for this color. How about Silverberry? You can see tiny flecks of the berries in the cake and I think the color is lovely, especially with the lavender frosting. If you want a more purple cake, feel free to add some gel food color to the batter. I used Wilton Violet gel food color to achieve the pretty lavender cream cheese frosting. The extra butter and the addition of heavy cream makes this frosting silky and spreadable.
I’m obsessed with edible flowers lately, so I garnish my baked goods with them whenever I can get my hands on some. I found these pansies in the produce department of my local food market. If you can’t find pansies, pesticide free violets or rose petals would also be pretty. Make sure to apply them to your cake right before serving, since they are delicate and will wilt over time. Brush some of your berries with a little dab of edible gold luster dust for an extra regal touch.

Instructions
Purple Berry Cake
-
Preheat the oven to 350º F (180ºC). Like the bottoms of two 6-inch round cake pans with parchment paper circles. Grease and flour the insides.
-
Purée the berries in a blender or small food processor. Strain the puréed berries through a sieve. Reserve 2/3 cup (150g) of the berry puree. Set aside the remaining puree for the syrup.
-
In a medium-size bowl, whisk together the flour, baking powder, baking soda, and salt until well combined.
-
In a large bowl, beat 1 1/4 cups (250g) of sugar with the oil, eggs and vanilla extract, with an electric mixer on medium speed, until light and fluffy. Stir in the reserved 2/3 cup berry purée. Add the flour mixture in two additions, alternating with the buttermilk, beating at low speed just until combined.
-
Pour the batter evenly into the prepared cake pans. Bake until a toothpick inserted into center of cakes comes out clean, about 30-35 minutes. Cool the cakes in the pans for 10 minutes. Remove the cakes from pans and transfer them to cooling racks to cool.
-
While the cakes are baking, make the berry syrup. In a small saucepan, heat the remaining berry purée with the remaining 1/4 cup sugar (50g) and 1/4 cup (59ml) of water over medium-low heat. Stir together and cook until sugar is dissolved. Set aside to cool.
-
Split each cooled cake llayer into two and brush with berry syrup. Fill and frost the cake with Silky Cream Cheese Frosting.
