Preheat the oven to 350℉
Grease and flour three 8 x 2 inch round cake pans - Cut a waxed paper or parchment paper circle and place in the bottom of each pan.
In a medium size bowl add the flour, baking powder, baking soda, cinnamon, nutmeg, ginger and salt. Whisk at least 30 seconds to blend. Set aside.
In another bowl, add the pumpkin, vegetable oil, vanilla extract, and milk. Stir to blend and set aside.
In the bowl of your mixer, beat the softened butter until smooth. Add the white and brown sugar and mix on medium speed 3 to 5 minutes or until light and fluffy.
Add the eggs one at a time, mixing after each until the yolk is blended.
With the mixer on low speed, add the flour mixture and the pumpkin/milk mixture alternately. Begin and end with the dry ingredients (3 additions of dry and 2 of wet). After the last addition of dry ingredients, mix just until combined.
Gently stir in the mini chocolate chips. Divide the batter between the three prepared 8 inch cake pans.
Bake at 350℉ for 25 to 28 minutes or until a toothpick comes out clean or with just a few crumbs attached.
Allow the cake layers to cool in their pans on a wire rack for 10 minutes before turning them out. Don't forget to peel off your parchment or wax paper if your pans were lined! (Easy to forget, especially with wax paper as it is more transparent)
