Mix berries, sugar, cinnamon and lemon juice together.
Place berries into a 9 x 13 pan.
Cover berries with dry cake mix.
Cover cake mix with grated butter.
Bake for 30 minutes until golden brown. Half way through baking time check to make sure butter has covered all the cake mix. Use a spoon to spread some if needed.
Serve warm, top with ice cream.

Notes
You can vary the flavor of cake mix you use. Sometimes I use white, yellow, butter flavored and even lemon cake mix. They all work great.You can also switch out the fruit and use apples, peaches, cherries, or any kind of berry.
