Mill the 2 1/3 cup (500g) soft white wheat berries. Set aside 1/3 cup for the streusel topping.
Preheat the oven to 350° F. Prepare either (1) 9x13 baking dish or (2) 8x8 baking dishes by spraying with cooking spray, I use avocado oil, you can also use parchment paper.
In a large mixing bowl, add the dry ingredients: fresh milled soft white wheat flour, 1 cup sugar, 1 tbsp baking powder, 1 tsp salt, and 1 tsp ground cinnamon. Mix to combine.
Cut the 2 sticks of butter into small cubes and spread over the dry ingredient mixture. With a pastry blender, cut in the butter until the mixture resembles small crumbs.
In a separate bowl, add the wet ingredients: 2 slightly beaten eggs, 1 1/4 cup milk, and 1 tsp vanilla. Mix to combine.
Then add the wet ingredients into the dry ingredients + butter mixture. Mix again until combined.
Spread half of the batter into the bottom of the prepared baking dish(es). Spread the cherry pie filling on top as an even layer. Then spread the remaining batter over the cherry pie filling. Add it to the dish in small globs using the spatula, don't try to dump it and spread it. Then try to spread it out so it covers the cherry pie filling without mixing with it.
