Preheat oven to 350 degrees F. Grease a tube pan. Peel, core and chop apples into chunks. Toss with cinnamon and 5 tbsp. sugar and set aside.
Sift together flour, baking powder and salt in a large mixing bowl. In a separate bowl, whisk together oil, orange juice, sugars 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 1 1/2 hours, or until a tester comes out clean.
Towards the end of baking, heat sauce ingredients in a saucepan over medium heat until butter is melted and sauce is hot. You can also make this ahead of time and reheat it prior to serving.
Serve warm sauce over warm cake. Top with ice cream.
