Preheat your oven to 375°F (190°C) and line a muffin tin with paper liners or spray with non-stick spray.
In a large mixing bowl, whisk together the flour, sugar, baking powder, and salt until well combined.
In another bowl, mix the melted butter, milk, eggs, and vanilla extract until smooth.
Pour the wet ingredients into the dry ingredients and stir gently until just combined. Do not overmix; it’s okay if there are some lumps in the batter.
Gently fold in the raspberries and white chocolate chips being careful not to crush the raspberries.
Divide the batter evenly among the muffin cups, filling each about 2/3 full.
Bake for 18-20 minutes, or until a toothpick inserted in the center comes out clean.
Let the muffins cool in the tin for 5 minutes before transferring them to a wire rack to cool completely.
Notes
Serve the muffins warm on a decorative platter, garnished with a few extra raspberries and a dusting of powdered sugar for an elegant touch.
