Preheat your oven to 425°F (220°C). Add the flour, baking powder, and salt to a large bowl. Stir everything together until evenly combined so the leavening agent is distributed throughout the flour.
Cube the cold butter and add it to the flour mixture. Use a pastry cutter to work the butter into the flour until the mixture resembles coarse crumbs. Small pieces of butter should still be visible throughout the mixture.
Create a well in the center of the flour mixture and pour in the cold buttermilk and honey. Stir gently using a silicone spatula until the ingredients just come together. Avoid overmixing because it can make the biscuits dense.
Transfer the dough onto a lightly floured surface. Use your hands to gently shape it into a rectangle. The dough may look a little rough at this stage, which is perfectly normal.
Fold one side of the rectangle toward the center and then fold the opposite side over it. Rotate the dough and flatten it back into a rectangle. Repeat this folding process several times to build beautiful flaky layers.
Pat the dough into a rectangle about one inch thick. Use a biscuit cutter and press straight down without twisting. Twisting can seal the edges and prevent the biscuits from rising properly.
Arrange the biscuits on a baking sheet and place them in the preheated oven. Bake for about 15 minutes or until the tops are beautifully golden brown and the layers have fully risen.
While the biscuits are still warm, mix the honey and melted butter together. Brush the mixture generously over the tops for a sweet and glossy finish that adds incredible flavor.
