In a food processor, pulse remaining 3 cups flour, baking powder, baking soda, sugar, and salt. Add the cold butter and pulse to form coarse crumbs. Transfer to a large bowl.

Lightly sprinkle top and sides of mound with some flour from dish to coat. With floured hands, place biscuit in greased baking pan, leaving excess flour behind in dish. Repeat to form 12 mounds in total, arranging in 3 rows of 4 in baking pan, spacing slightly apart.
