In a large bowl, combine apple slices, 1/4 cup sugar, and cinnamon. Set aside.
2Spray a 10-12 cup bundt pan with cooking spray and dust with flour. Set aside.
3In a bowl, combine remaining 2 cups of sugar, flour, baking powder, and salt. Make a well and pour in oil, vanilla, apple juice, and eggs. Stir to just combine the ingredients and the flour mixture is incorporated.
4In the bundt pan, put about one-half of the batter and top with the apples making sure they don't touch the sides of the pan. Top with the remaining batter. Bake for about 1 hour or until the top of the cake is golden brown. A long skewer or toothpickshould come out clean when inserted into the cake.
