Preheat your oven to 350°F (175°C). Prepare two 8-inch round cake pans by greasing and flouring them.
In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
In a large mixing bowl, beat the softened butter and granulated sugar until light and fluffy, about 4 minutes.
Add the eggs one at a time, mixing well after each addition.
Stir in the melted white chocolate until just combined.
Gradually alternate adding the dry ingredients with the milk, starting and ending with the dry mix. Stir until just combined; be careful not to overmix.
Gently fold in the fresh raspberries, taking care not to crush them.
Divide the batter evenly between the prepared cake pans and smooth the tops.
Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
Allow the cakes to cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
Once cooled, frost the cakes with your choice of frosting and garnish with fresh raspberries.
Notes
Use room-temperature ingredients for smoother batter and better rise. If raspberries are very soft, toss them in a teaspoon of flour before folding into the batter to prevent them from sinking.
