Preheat oven to 350 degrees. Grease and flour a bundt pan and set aside.
Add flour, baking powder, baking soda, cinnamon, nutmeg, clove, ginger, and sea salt and whisk together until uniform in appearance.
In another bowl, combine brown sugar, pumpkin puree, milk, butter, eggs, and vanilla extract until uniform.
Add wet ingredients to dry ingredients and stir until just combined and no dry pockets remain. Peel and shred apple then mix into cake batter.
Transfer batter to prepared bundt pan and bake on center oven rack for about 45 minutes or until a toothpick inserted into multiple parts of the cake comes out clean. Cool for about 10 minutes in pan then remove and allow to cool completely.

Notes
PreparationIf you don't have a stand mixer or hand mixer, you can use mixing bowls, a whisk, and a silicone spatula with a little elbow grease and stir it by hand. And I recommend hand stirring to finish mixing the batter in any case to avoid over-mixing, which can result in a tough cake.To make sure your cake doesn't stick, I recommend preparing your bundt pan with butter or non-stick oil spray and flour, even if it's a non-stick pan. Here's a visual on how to grease and flour a bundt pan.I recommend baking the cake on the middle rack for even cooking with a sheet pan place on the lower rack to catch any drips.StorageWith the cream cheese frosting, you should refrigerate this cake in an airtight container to keep it from spoiling. Keeps for up to two weeks. Allow it to come to room temperature before enjoying.
