Preheat oven to 325°F (160°C). Grease a 9×13-inch baking pan with non-stick spray.

In a medium bowl, sift together flour, baking soda, cinnamon, nutmeg, and salt; set aside.

In a large mixing bowl, beat oil, granulated sugar, and brown sugar until combined. Add vanilla and eggs, one at a time, mixing well.

Gradually add the dry mixture to the wet mixture, mixing well after each addition. (Batter will be very thick.)

Fold in chopped apples with a sturdy spoon.

Spread batter evenly into the prepared pan. Bake 50–60 minutes, or until a toothpick inserted in the center comes out clean.

While cake bakes, prepare glaze: combine butter, brown sugar, granulated sugar, cream, and vanilla in a saucepan. Heat over medium until simmering, stirring often. Remove from heat and cool 5 minutes.

Pour warm glaze over cake while still warm.

Slice, serve, and enjoy!
