Preheat oven to 350 degrees F (175 degrees C). Grease and flour an 8-inch pie pan.
In a large bowl, beat together the butter and sugar until creamy. Beat in the eggs one at a time, then add the vanilla extract.
In a separate bowl, combine the flour, baking powder, and salt. Gradually add this to the butter mixture and mix until all the ingredients are combined.
Stir in the walnuts and raisins. Pour the mixture into the prepared pie pan.
Bake in the preheated oven for 25 minutes, or until a toothpick inserted into the center comes out clean.
Allow the pie to cool before serving.
