Preheat your oven to 350°F (175°C) and grease a 9-inch cake pan.

In a large mixing bowl, sift together flour, baking powder, baking soda, cinnamon, and nutmeg.

In another bowl, whisk together eggs, brown sugar, and vegetable oil until smooth. Add vanilla extract.

Gradually fold the dry ingredients into the wet mixture and then gently add the chopped fresh apples.

Pour the batter into the prepared cake pan and smooth the top. Bake for 35-40 minutes or until a toothpick comes out clean.

After baking, cool the cake in the pan for about 10 minutes then transfer to a wire rack to cool completely.

In a skillet over medium heat, melt butter, add sugar, and stir until dissolved. Add sliced apples and cook until tender and golden.

In a chilled bowl, whip the heavy cream until soft peaks form, adding powdered sugar if desired.

Spread the whipped cream over the cooled cake and top with the caramelized apples.

Dust with cinnamon or nutmeg before serving.
