Preheat oven to 425. Line a 9″ round cake pan with sheet with parchment paper.
Grate your frozen butter using a box grater then throw it back in the freezer until you need it.
In a large bowl, whisk together the flour, baking powder, baking soda, sugar, salt, garlic powder and chives.
Add the frozen butter and shredded cheese to the flour mixture and toss it all together using a fork.
Make a well in the middle and add the buttermilk – stir using the fork just until it comes together.
Empty the dough on to a lightly floured surface and gently bring it together with your hands to form it in to a rectangle. Note, it will be crumbly at first but it will come together as you do the rolling and folding. You do not want a very moist dough or you will have stodgy biscuits.
Sprinkle very lightly with flour and roll it out to about 3/4 of an inch, then fold the dough in thirds on top of each other. Roll again and repeat the process 3-4 more times. This gives you the layers.
Roll the dough down to a rectangle lightly until it is about an inch thick.
Use a 3 inch biscuit cutter to cut out the biscuits. Push it straight down and pull straight up, making sure you don’t twist the cutter.
Once you have cut out as many as you can, gently roll together all the leftover bits and continue to cut out biscuits until the dough is pretty much all gone. (I usually make 8 total and that fits the pan perfectly.)
Place the biscuits on the pan, one in the middle and the others around it- they will be lightly touching each other.
Place the whole pan in your freezer for 10 minutes to make sure those ingredients are still cold.
Brush the tops of the biscuits with milk, buttermilk or cream.
Bake at 425 for 14-16 minutes
Remove from oven and brush with melted butter immediately then serve!
