Preheat oven to 350F.
Grease and flour a mini bundt pan. Set aside.
In a small bowl, whisk together the flour, baking powder and salt. Set aside.
In a large bowl, cream together the vegetable oil and white sugar until light-colored and creamy, about 2 minutes.
Beat in the eggs and vanilla extract.
Beat in half of the dry ingredients, then 1 cup of the milk, then the remaining dry ingredients until just incorporated.
Portion out the batter into the prepared bundt pan, filling each cavity about 2/3 of the way full.
Bake for 20-24 minutes until lightly golden and an inserted toothpick or cake tester comes out clean.
While the bundt cakes are baking, prepare the cream cheese frosting.
