Preheat oven to 350 degrees. Grease a 9x13-inch pan and set aside.

In a medium bowl, combine the flour, sugar, baking soda, salt and cinnamon.

In a large bowl, beat the eggs until light and foamy. Add the oil and vanilla and mix well.

Stir in the flour mixture with a spoon and continue stirring the batter until the flour disappears.

Add the apples and nuts; mix well.

Scrape the batter into prepared pan and bake for 40-45 minutes, or until a toothpick inserted in the center comes out clean. Set the cake on a wire rack.

While the cake is still hot, prepare the glaze.

Combine the brown sugar, butter, vanilla and heavy cream in a medium saucepan.

Cook over medium heat, stirring often, until the mixture comes to a gentle boil. Continue cooking for 3 minutes.

Spoon the hot glaze over the still warm cake.

Let the glazed cake cool completely before serving straight from the pan.
