Vanilla Glazed Blueberry Biscuits are buttery, filled with blueberries, topped with sweet glaze, and take 15 minutes prep. They're DELICIOUS!
Preheat oven to 500°F.
Place flour, sugar, baking powder and salt in large mixing bowl; stir, to combine. Cut in COLD butter with pastry blender or two forks until butter becomes the size of peas. Slowly drizzle buttermilk into the dry ingredients; stir only until is incorporated into ingredients. Mixture should pull away from sides of bowl and form a shaggy dough ball.
Generously sprinkle a cutting board or workspace with extra flour. Place dough ball onto floured workspace; sprinkle dough with more flour. Using your fingers, press dough and flatten it out until 1/2" thick. Place FROZEN blueberries onto HALF of the dough, leaving a small edge bare around the edges of that half. Carefully fold the empty half of the dough up and over the blueberries, until edges meet. NOTE: This can be a bit challenging! The blueberries tend to roll out the sides... just keep stuffing them back in the best you can! Turn the dough over, and gently knead it with your hands a couple of times. Re-flatten dough with your hands until 1" thick. Don't worry if blueberries "bleed" color onto dough!
Use a biscuit cutter, rim of a glass glass, or a canning jar lid to cut out the biscuits. NOTE: When you press down on dough, don't twist biscuit cutter around. Simply press straight down to cut the biscuit, then remove dough circle. *Using canning jar lid or a cup can yield 8 biscuits from the dough. If using large biscuit cutter (4"), you may only get 6 biscuits.
Place biscuits into a 9" cast iron skillet (or oven-safe skillet). Make sure biscuits are touching each other. This allows biscuits to rise up instead of widen out. Place in preheated oven; bake at 500°F. for 6 minutes. While biscuits bake, melt 4 T. butter in small pan. Once biscuits have cooked for 6 minutes, pull skillet out of oven. Brush surface of biscuits with melted butter. Don't skip this step, and use all the melted butter! Put biscuits back into oven: continue baking another 4-6 minutes. Oven temps can vary, so keep an eye on them. When done, biscuits should be golden brown on top and a toothpick inserted into the middle of a biscuit should come out clean. Remove from oven; put skillet on wire rack; let biscuits cool (in skillet) for10 minutes.
While biscuits cool, make vanilla glaze. Stir powdered sugar, milk and vanilla together in small bowl, until glaze is smooth and lump-free. Once biscuits have cooled 10 minutes, use a pastry brush to fully cover them with glaze.
Let cool until glaze has firmed up, then serve. Use a knife to separate biscuits, then a spatula to remove biscuits from skillet. Leftovers can be reheated in microwave on medium-low heat.
