Sift the flour, baking powder, sugar, and salt into a large mixing bowl.
Then quickly grate frozen butter into the flour mixture—grated frozen butter ensures even fat distribution throughout the dough, making light and fluffy biscuits. (Alternatively, cut butter into flour mixture with a pastry blender until it resembles coarse crumbs (it may take around 5 minutes). The mixture should be crumbly with pea-size chunks. (Let the bowl chill in the fridge to keep the butter cold if you're not making the biscuits immediately.)
In a small bowl, mix the honey and buttermilk.
Make a well in the center of the flour and add the honey and buttermilk mixture. Mix just until the ingredients come together.
Sprinkle flour on a board or clean surface, and knead dough 4-5 times.
Gently pat the biscuit dough with your hands or roll it with a rolling pin to about ½ inch thick.
Cut out the biscuits with a 2- or 3-inch cookie cutter or a rim of a glass. Push straight down firmly, then pull the cutter up. Gently loosen the dough from the biscuit cutter with your fingers, then arrange the biscuits on your greased or parchment-paper-lined baking sheet, spacing them out equally.
Knead leftover dough scraps together and repeat until all the biscuit dough is used up. The last few biscuits might not be as pretty as the others, but they will still pass the taste test.
Lightly brush each biscuit with buttermilk or cream.
Bake them at 400℉ (205℃) for 12-15 minutes or until lightly browned.
Remove them from the oven, immediately brush them with honey or honey butter, and serve with more honey butter on the side if desired.
