Step 1: Preheat Your Oven - Preheat your oven to 375°F (190°C). This ensures that your muffins will rise beautifully and bake evenly.
Step 2: Prepare the Muffin Tin - Line a 12-cup muffin tin with paper liners or grease it lightly with non-stick spray. This will help prevent the muffins from sticking.
Step 3: Mix the Dry Ingredients - In a large mixing bowl, whisk together the 3 cups of flour, 1 tablespoon of baking powder, and 2 cups of granulated sugar until well combined.
Step 4: Incorporate the Butter - Add the 1/2 cup of butter pieces to the dry mixture. Using a pastry cutter or your fingers, mix until the mixture resembles coarse crumbs.
Step 5: Whisk the Wet Ingredients - In another bowl, whisk together the 2 large eggs, 1 cup of milk, and 1 teaspoon of vanilla extract until smooth.
Step 6: Combine Wet and Dry Mixtures - Pour the wet ingredients into the dry mixture and stir gently until just combined. Be careful not to overmix, as this can make your muffins dense.
Step 7: Fold in the Blueberries - Gently fold in the 1 cup of fresh blueberries using a rubber spatula. This will keep the berries intact and prevent them from breaking apart.
Step 8: Fill the Muffin Tin - Scoop the batter into the prepared muffin tin, filling each cup about 3/4 full. This will allow them to rise nicely without overflowing.
Step 9: Brush with Melted Butter - Brush the tops of the muffins with the 2 tablespoons of melted butter for a rich, golden finish.
Step 10: Bake - Bake in the preheated oven for 20-25 minutes, or until a toothpick inserted into the center comes out clean. The tops should be golden brown and slightly domed.
Step 11: Cool and Enjoy - Remove the muffins from the oven and let them cool in the tin for about 5 minutes before transferring them to a wire rack to cool completely. Enjoy your fresh Bakery Style Blueberry Muffins with a cup of coffee or tea!
