Fudge Ripple Brownies

box brownie mix (or double just the brownie portion of this recipe for scratch brownies and make as directed), plus water, oil, and eggs called for on the box

mini semi-sweet chocolate chips

brick-style cream cheese, softened

cold 2% milk (must be real milk and not almond, soy, etc. or pudding will not set up), divided

box white chocolate instant pudding mix (if you cannot find it, vanilla or cheesecake flavor may be substituted)

whipped topping, thawed (I used fat free)

about 1/4 cup chocolate sauce (such as Hershey’s)
