Serve with ice cream, if desired.
Preheat oven to 350 degrees. Grease and lightly flour a 10’ bundt pan. Peel, core and chop apples into chunks. Toss with pecans, cinnamon, and ¼ cup of the sugar and set aside.
Stir together flour, baking powder and salt in a large mixing bowl. In a separate bowl, whisk together oil, orange juice, sugar and vanilla. Mix wet ingredients into the dry ones, then add eggs, one at a time. Scrape down the bowl to ensure all ingredients are incorporated.
Pour half of batter into prepared pan. Spread half of apples over it. Pour the remaining batter over the apples and arrange the remaining apples on top. Bake for about 1½ hours, or until a tester comes out clean. Cool in pan on rack 15 minutes, then invert onto rack to cool completely in the pan, about 1 hour, and then turn it out onto a plate.
While the cake cools, add all the glaze ingredients to a small bowl and whisk together until smooth. Drizzle glaze over the top of cake, slice, add ice cream, and serve.
