Instructions
Preheat Oven and Prepare Baking Sheet:
Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper or lightly grease it.
Make Biscuit Dough:
In a large bowl, whisk together flour, baking powder, baking soda, and salt. Cut in the cold butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs.
Gradually add buttermilk, stirring until the dough comes together. If the dough is too sticky, add a little more flour.
Roll Out Dough:
Turn the dough out onto a floured surface and knead gently a few times until smooth. Roll the dough into a rectangle about 1/4 inch thick.
Prepare Filling:
In a small bowl, mix together the brown sugar and cinnamon. Spread the softened butter evenly over the rolled-out dough, then sprinkle the cinnamon-sugar mixture on top.
Roll and Cut Biscuits:
Starting with a long side, roll the dough tightly into a log. Slice the log into 1-inch thick rounds. Arrange the rounds on the prepared baking sheet, leaving some space between each.
Bake:
Bake in the preheated oven for 12-15 minutes, or until the biscuits are golden brown and cooked through.
Prepare Glaze:
While the biscuits are baking, whisk together powdered sugar, milk, and vanilla extract in a bowl until smooth. Adjust the consistency with more milk or sugar if needed.
Finish and Serve:
Remove the biscuits from the oven and let them cool for a few minutes. Drizzle the glaze over the warm biscuits before serving.
