Preheat the oven to 350°F (175°C). Grease and flour a baking pan.

In a mixing bowl, combine the dry ingredients and set aside.

In another bowl, cream together the butter and sugar until light and fluffy.

Add the eggs one at a time, beating well after each addition.

Stir in the vanilla and chopped apples.

Gradually add the dry ingredients to the wet mixture, mixing until just combined.

Pour the batter into the prepared baking pan and smooth the top.

Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean.

Let cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
