Preheat your oven to 350°F (175°C) and grease a bundt or cake pan.
Toss chopped apples with cinnamon; set aside.
In a bowl, whisk together flour, baking powder, cinnamon, and salt.
In another bowl, cream melted butter and sugars until fluffy; add eggs one at a time.
Gradually combine dry ingredients into the wet mixture; gently fold in apple chunks.
Pour batter into the prepared pan and bake for 45-50 minutes or until a toothpick comes out clean.
For the glaze, combine brown sugar and heavy cream in a saucepan over medium heat until bubbly (about 5 minutes). Drizzle over cooled cake.
