Whisk the sour cream, heavy cream & chives together then fold them into the dry ingredients to form a soft dough, making sure everything is incorporated without over mixing.
Knead the dough just enough to make it hold together ( about 30 seconds ) then roll it out into 3/4 inch sheet and cut out 12 rounds with your biscuit cutter.
Line a stainless steel cookie sheet with parchment paper and arrange the cold biscuits on it. Bake in the preheated oven for 15-18 min until golden brown on top.
