Preheat the Oven: Set the oven to 425°F so it’s fully hot before baking. High heat helps the biscuits rise tall and bake evenly.
Mix the Dry Ingredients: In a large bowl, whisk together the flour, baking powder, baking soda, and salt until evenly combined.
Cut in the Butter: Add the cold butter cubes straight from the fridge or freezer. Cut them into the flour using a pastry cutter or pulse in a food processor until the mixture looks like coarse crumbs with visible butter pieces.
Add Buttermilk and Honey: Pour in 1 cup of cold buttermilk and drizzle in the honey. Gently mix just until a shaggy, crumbly dough forms. Do not overmix—the dough should look rough.
Shape the Dough: Turn the dough onto a lightly floured surface and gently bring it together with your hands. Pat it into a rectangle about ¾ inch thick.
Fold for Flaky Layers: Fold the dough in thirds like a letter, rotate it 90 degrees, and flatten again. Repeat this folding process two more times, then flatten the dough one last time to about ¾ inch thick.
Cut the Biscuits: Press straight down with a biscuit cutter without twisting. Gather and re-roll scraps as needed. You should end up with about 8 to 11 biscuits, depending on cutter size.
Arrange and Brush: Place the biscuits close together on a baking sheet or in a cast iron skillet so they help each other rise. Lightly brush the tops with the reserved buttermilk.
Bake Until Golden: Bake for 18 to 20 minutes, until the tops are golden brown and the biscuits have risen tall.
Finish with Honey Butter: Stir the melted butter and honey together, then brush over the hot biscuits for a glossy, lightly sweet finish. Serve warm.
