Preheat oven to 350°F (175°C). Grease and flour a Bundt pan.

In a large bowl, mix together sugar, oil, and eggs until well combined.

Add raisins, apples, and nuts to the mixture and stir to distribute evenly.

In a separate bowl, whisk together flour, soda, and baking powder.

Gradually add the dry ingredients to the apple mixture, mixing by hand until just combined.

Stir in vanilla extract.

Pour batter into the prepared Bundt pan.

Bake for 60 minutes, or until a wooden skewer inserted into the center comes out clean.

Let cake cool in the pan for 10 minutes before inverting onto a wire rack to cool completely.
