I had friends over for lunch so I made some baked pasta with garlic toasts and these marble brownies. If you are a chocolate-cheesecake lover these are for you. Very easy to make. Simply use your favorite brownie mix and place all ingredients as directed in a bowl, then on a separate bowl mix 1 package of philadelphia cheese at room temperature with 1 tablespoon of vanilla, 1/2 cup of sugar and 1 egg. Grease the pan with butter - I like glass- and place first you brownie mix, then the cheese mix on top without folding it. Run a knife through it just to create a pattern. Bake at 350 for 35 min. or until a toothpick comes out clean. Let it cool before cutting into squares. Decorate it with mint, strawberries and/or your favorite ice cream.
