Preheat your oven to 350°F (175°C) and grease two 9-inch round cake pans.
In a large bowl, cream together the softened butter and sugar until light and fluffy.
Add the eggs, one at a time, mixing well after each addition.
Stir in the vanilla extract and mix until combined.
In a separate bowl, whisk together the flour and baking powder.
Gradually add the dry ingredients to the wet mixture, alternating with milk.
Fold in the white chocolate chips and fresh raspberries gently.
Divide the batter evenly between the prepared pans.
Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean.
Let the cakes cool in the pans for 10 minutes before transferring to wire racks to cool completely.
