For the crust, Mix the dry ingredients together and then cut in the softened butter.
(You can also do this in a food processor with a steel blade, using chilled butter that's been cut into chunks.) Spread the mixture out on
the bottom of a 9 inch by 13 inch cake pan and press it down with a spatula. Bake at 350 Degrees F. for 15 Minutes. (Don't shut off the
oven - you'll need it for the second step.)
To make the filling, You can do this by hand, but it's a lot easier with an electric mixer.
Soften the Cream Cheese and beat it with the Mayonnaise until it's
smooth. Gradually add the Sugar. Add the Eggs, one at a time, beating
after each addition. Melt the Chocolate Chips in a microwave safe bowl
for 3 minutes. (Chocolate Chips may retain their shape, so stir them to
see if they're melted.) Let them cool for a minute or two, and then
gradually add the chocolate, mixing thoroughly. Then mix in the Vanilla.
Pour the finished mixture on top of the crust you just baked. Bake at
350 Degrees F. for 35 Minutes. Let it cool to room temperature. Make the glaze: In a small saucepan, combine the butter, corn syrup and water. Cook over low heat, stirring constantly. Bring to just boiling; remove from heat. Add the chocolate chips; stir until they are melted and the mixture is smooth. Cool to room temperature.
Pour the glaze over the top of the cake and chill for at least 4 hours. Cut into small squares.
