How to Make ~ Family Favorite Blackberry Cake ~


  1. In a medium saucepan over medium heat, stir together the blackberries, sugar, corn starch, salt, cinnamon, water and reserved juice. Bring to a slow boil stirring constantly. Boil for 2 minutes. Remove from heat and stir in the extract and lemon juice. Set aside.
  2. Preheat oven to 325 degree F.
    Grease a 9 x 13 baking dish. I use bakers joy.

    In a large bowl, stir together the cake mix, flour, sugar, and salt until well mixed.

    Add the water, sour cream, vegetable oil, egg whites, and both extracts. Then beat with an electric mix on low until all of the ingredients are mixed and moistened yet some lumps still remain. Four to five minutes.
  3. Now, pour the batter into the prepared cake pan, and bake until the top is a light golden brown and a toothpick inserted into the center of the cake comes out clean, about 25 - 30 minutes.
  4. Remove from oven and leave cook for 10 minutes. Take a fork and prick the top of the cake evenly, all over.
  5. Spread the prepared blackberries evenly over the cake. Leave this cool completely.
  6. Make whipped topping by adding the cream, sugar and extract to a chilled bowl. Beat until stiffer peaks form just don't over beat.
  7. Spread atop the cooled berries and I sprinkled with sliced almonds and some toasted coconut I had left from another recipe.

    Keep chilled and covered when not serving.

    My family loves this dessert. I hope you do as well.
