1. **Preheat Oven**: Preheat your oven to 350°F (175°C). Grease a bundt pan thoroughly.
2. **Prepare Apples and Raisins**: Peel, core, and slice the apples. Sprinkle the apple slices and raisins evenly in the greased bundt pan.
3. **Prepare the Batter**:
– In a large bowl, cream together the butter and sugar until light and fluffy.
– Add the eggs one at a time, beating well after each addition.
– Stir in the vanilla extract.
– In a separate bowl, combine the flour, baking powder, and salt.
– Gradually add the dry ingredients to the wet ingredients, alternating with the milk, beginning and ending with the flour mixture.
– Mix until just combined.
4. **Assemble**: Pour the batter over the apples and raisins in the bundt pan. Use a spatula to spread the batter evenly over the fruit.
5. **Bake**: Bake in the preheated oven for 45-55 minutes, or until a toothpick inserted into the center of the cake comes out clean.
