Preheat oven to 375°F. Line a 12-cup muffin tin with liners.
In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.
In another bowl, combine buttermilk, oil, eggs, and vanilla until smooth.
Pour wet ingredients into dry ingredients and stir until just combined.
Gently fold in raspberries and white chocolate chips.
Divide batter evenly among muffin cups.
Bake 18-20 minutes or until a toothpick comes out clean.
Cool in the pan 5 minutes before transferring to a wire rack.
