Start your day with a batch of fluffy blueberry muffins. This recipe is incredibly easy to make and yields moist and tender muffins bursting with juicy blueberries. Start by whisking together flour, sugar, baking powder, and salt in a bowl. In a separate bowl, mix together melted butter, milk, and eggs. Combine the wet and dry ingredients, then gently fold in fresh or frozen blueberries. Divide the batter into a muffin tin lined with paper liners and bake in a preheated oven until golden brown and a toothpick inserted into the center comes out clean. Let the muffins cool slightly before enjoying. These fluffy blueberry muffins are perfect for breakfast or as a snack on the go.
