Tall bar cookies with a thick graham crust and a topping of assorted chips and cookies held together by a cheesecake batter.
If the idea of having a partial can of condensed milk drives you crazy, you can try adding it all. However, the bars will be sweeter, and they are pretty sweet as is.
I've been making the bars in a 9x9 inch square pan, but if you have loads of chocolate chips and want to make a 9x13 inch pan, try the following measurements.
2 1/4 cups graham cracker crumbs
6 T. light brown sugar
6 T. all-purpose flour
12 T. (6 oz) unsalted butter, melted
1/4 teaspoon salt
14 ounces (1 can) of condensed milk
12 oz cream cheese, softened
1 large egg plus 2 tablespoons beaten egg
1 1/2 teaspoon of vanilla extract
1 1/2 cups white chips
1 1/2 cups or more miniature Oreos (approximate, maybe less)
3/4 cup coarsely chopped nuts
3 cups assorted chocolate chips and M&Ms (maybe less)
