- Preheat the oven to 375°. In a large bowl, toss the blackberries with the confectioners’ sugar, lemon juice and zest. In another large bowl, using your hands, combine the oats with the brown sugar, coconut, flax seeds, cinnamon, 1 teaspoon of salt, the remaining 6 tablespoons of butter and the remaining 1/2 cup of flour; mix until crumbly.
- On a lightly floured work surface, roll the dough out to a 15-inch round, about 1/2 inch thick. Transfer the dough to your cast-iron griddle and pat into the bottom and up the side of the griddle, letting about 2 inches of dough drape over the side. Spread the oat crumble over the dough in the bottom of the griddle and top with the blackberries. Fold the overhanging dough over the blackberries. Brush the top of the dough with the beaten egg yolk and sprinkle with granulated sugar. Bake for about 45 minutes, until, then tent the crust with foil, leaving the blackberries exposed.
