1
Preheat oven to 350 degrees F. Generously butter and flour the bundt pan.

2
Whisk the flour, 1 1/3 cup of the sugar, 1 teaspoon of the pie spice, the baking powder, baking soda, and salt together in a large bowl.
-
3
Toss the apples with the remaining 1/4 cup sugar and 1/2 teaspoon pie spice and set aside.
-
4
Whisk the eggs and oil together in another bowl.
-
5
Whisk in the sour cream, orange zest and juice, and vanilla.
-
6
Pour the egg mixture into the dry ingredients and stir with a wooden spoon just until combined but still a bit lumpy.
-
7
Using a slotted spoon, scatter about 1/2 cup of the apples in the bottom of the bundt pan.
-
8
Put about 1/3 of the batter on top.

9
Repeat, alternating with the remaining apples and batter, ending with the batter.

Bake the cake until it pulls away for the sides of the pan and a skewer inserted into the center of the cake comes out clean, about 1 hour and 15 minutes.
-
11
Cool 10 minutes and invert onto a rack placed over a baking sheet.
-
12
Cool.

13
(The cake can be prepared to this point a day ahead.)
-
14
To make the caramel: Stir the sugar, corn syrup, and 2 tablespoons water in a small saucepan.
-
15
Bring to a boil over medium heat and cook, swirling the pan but not stirring, until the sugar is dark amber-colored caramel, about 15 minutes.
-
16
Pull pan from the heat and carefully pour in the cream (take care it will splatter).
-
17
Stir in the pecans, vanilla, and salt.
-
18
Cool until caramel becomes thick and syrupy, then evenly pour over the cake and cool until set.

Cook's Note: We like to bake this cake the day before we serve it so the flavors and texture ripen.

If you bake it a day ahead glaze with the caramel the day you plan to serve it.
