Chocolate Cake With Blackberry Buttercream
7/8 cup caster sugar
1 teaspoon baking powder
1/2 teaspoon baking soda
40 grams cocoa powder
2 teaspoons vanilla
3/4 cup sour cream
3 tablespoons shortening
3 tablespoons blackberry jam
4 cups powdered sugar
1 teaspoon vanilla
1/2 teaspoon salt
4 tablespoons milk
To Make the Cake
Pre-heat the oven to 350º F and grease the cake pan. If you are using normal cake rounds, you will need 2.
Beat in the butter until creamy. I ended up using 2 sticks of butter because my mixture wasn’t creamy with only 1 1/2 sticks.
Pour the chocolate mixture into the butter mixture and beat until fully incorporated.
The cake is done when a toothpick inserted comes out clean.
To Make the Frosting
Beat together the butter, shortening, and jam until smooth.
Add the powdered sugar, 1 cup at at time, until the frosting reaches the desired sweetness.
