1 (12-ounce) can Carnation evaporated milk, well chilled
1⅔ cups graham cracker crumbs
½ cup confectioners sugar
6 tablespoons margarine or butter, melted
1 (3-ounce) box lemon Jell-O gelatin
1 cup boiling water
1 (8-ounce) package cream cheese
1 cup granulated sugar
4 tablespoons fresh lemon juice, OR 2 teaspoons vanilla extract
To begin, shake the can of evaporated milk and refrigerate until well chilled, at least an hour.
In a small mixing bowl and using a wire whisk, dissolve the Jell-O in the boiling water, 1 to 2 minutes. Set aside to cool to lukewarm.
Combine graham cracker crumbs, confectioners sugar, and melted butter. Reserve 1/3 cup of the mixture for the topping. Press the remainder firmly into the bottom of an 11.5×7.5-inch (or similar) dish. Refrigerate or put in the freezer until needed.
In another large mixing bowl and using a mixer, beat together the cream cheese, granulated sugar, and lemon juice (or vanilla) until smooth and creamy. Beat in the cooled Jell-O until well blended. Refrigerate mixture for now.
Shake the can of chilled evaporated milk again and pour into another large mixing bowl. Beat on high speed of mixer until light and fluffy, 3-4 minutes. (It should have the consistency of beaten egg whites.) Beat in the cream cheese/Jell-O mixture.
Pour mixture over the chilled crust. Sprinkle top with the remaining crumb mixture. Refrigerate for several hours before cutting into squares.
You can use a larger pan, like 9 x 12-inch and the dessert will be thinner. If you have too much filling for the smaller pan, pour it into small bowls and refrigerate for a quick and creamy snack.
