Preheat your oven to 350F and grease 2 loaf pans.
Make the yellow cake mix according to the box instructions, adding in the vanilla pudding mix.
Make the devil's food cake mix according to the box instructions, adding in the chocolate pudding mix.
Transfer both prepared mixes into the loaf pans and bake for 25-30 minutes, or until set in the middle.
To make the frosting, whip 1 block of cream cheese with 2 cups milk and 1/2 sachet of pudding until smooth and combined. Add more milk to thin it out if it is too thick.
Repeat with the other flavor of pudding so you have both chocolate and vanilla cream cheese frostings.
Let your loaves cool before removing them from the pans.
Spread a thick layer of frosting on each and top with sprinkles for a pop of color.
Slice and enjoy!
