Pre heat oven to 350 degrees F. Grease the mini bundt pan with plenty of spray.
In a mixing bowl combine the brown sugar, granulated sugar, softened butter and vanilla. Mix until light and fluffy. Beat in the eggs and blend well.
Sift the flour, salt, baking powder and baking soda together in a separate bowl. Gradually add the flour mixture and 1/2 cup of milk by alternating a little of each at a time; incorporate each batch well before adding the next. Start with the flour and end with the flour. Add 1 cup of the mini chocolate chips to the batter and mix well.
Fill each well with batter - no more that 3/4's full. Tap the pan slightly to help the batter settle.
Place the bundt pan into the oven on the middle rack. Bake for 15 minutes - or until done.
Cool at least 5 minutes prior to flipping out onto a board or wire rack.
