6cupsblackberries 4 to 5 cups if they are large berries
1 to 2tablespoonssugar
In the bottom of a 9×13 baking dish, pour one box of yellow cake mix.
Spread blackberries over the top of the cake mix.
Sprinkle on 1 to 2 tablespoons of sugar (depending upon how sweet they are).
Pour 1 cup of water over the top of the berries and cake mix then shake the pan so water settles into the bottom. If berries aren’t very juicy, add a little more water. If they are plump, a little less.
Cut a stick of butter into 8 pieces and spread out over the top.
Bake at 350 for 35 to 40 minutes.
Slice and serve warm.
Note: The amount of sugar and water needed in this recipe can vary, depending on the berries. Before you start, taste the berries for juicy sweetness. Adjust sugar and water accordingly. Also, it is important to pour the water over the top and shake the pan. You want the berries and water to really settle into the pan!
