Preheat oven to 450°F and prepare a 9-inch pie pan by spraying it with nonstick spray.
Grate butter using the fine edge of your grater. Grate onto parchment paper and then place it in the freezer while you prepare the remaining ingredients. (I grab 1 stick of butter, which is 8 tablespoons, and then grate until there are 2 tablespoons left. I use the remaining 2 tablespoons as topping on the biscuits. This method utilizes all your butter and saves your fingers when grating!)
Add flour, baking powder, baking soda, and salt to a large bowl. Use a whisk to sift ingredients.
Get grated butter out of the freezer and, using a fork, incorporate into dry ingredients.
Add the garlic scapes, scallions, and cheese and mix.
Add in the buttermilk and stir until mostly combined, being careful not to overwork the batter.
Scoop out 6-7 even portions of the batter and place in the pie pan, one next to the other. (I use my hands, this gets a bit sticky.)
Cut the two tablespoons of butter into 6 thin slices and top each biscuit with the butter. Sprinkle with salt.
Bake for 15-20 minutes or until fluffy and golden brown.
Serve warm with more butter. (optional to add more butter)
