1-Preheat your oven to 400°F and prepare your baking pan by melting 1 tablespoon of butter in an 8×8-inch pan as it heats up this creates a golden base. Once melted, brush the butter evenly across the bottom and sides for even flavor distribution.

2-Next, in a large bowl, whisk together 3 cups all-purpose flour, ½ cup granulated sugar, 2 teaspoons baking powder, ½ teaspoon baking soda, and 1 ¼ teaspoons fine sea salt to blend the樂 ingredients thoroughly. Cut the remaining cold butter into small pieces and incorporate it using a pastry blender or your fingertips until you get a coarse mixture with some pea-sized pieces this step is crucial for that fluffy texture. Gently toss in 1 ½ cups fresh blueberries to avoid crushing them, then stir in 1 ⅔ cups cold buttermilk until no dry flour pockets remain, resulting in a thick, sticky batter.

3-Spread the dough evenly in the prepared pan, pressing it into the corners, and lightly spray a bench scraper with cooking spray to score the dough into 9 equal squares while keeping them connected. Bake for 40-45 minutes until the tops are browned and a knife inserted in the center comes out clean. After cooling for 5 minutes, prepare the honey butter by microwaving 2 tablespoons unsalted butter, 1 tablespoon honey, and a pinch of salt until melted, then stir to combine. Turn the biscuits out, flip them topside up, brush with the honey butter, and let cool another 10 minutes before cutting and serving warm.
