The Ultimate Frozen Mud Pie

I don't give in to cold temperatures, I defy them.  Doesn't matter what time of the year, this flavorful version of mud pie is one of my all-time favorites.  I had a hankerin' for it the other day, and once that happens, nothing can stop me.  It does like this:

Crust:
2 rows of Oreo sandwich cookies, crushed
3 T melted butter

Ice Cream Layer:
1/2 gal. Coffee Ice Cream, any brand, softened

Fudge Layer:
3 oz. unsweetened chocolate
3 T butter
1 c granulated sugar
1 12 oz. can evaporated milk
Pinch of salt
1 1/2 tsp vanilla

Top Layer:
1 1/2 c. heavy cream
1/3 c. Kahlua
1/4 cup confectioners' sugar

Butter a 9x13 dish.  Mix crust ingredients and press into bottom of dish.  Chill in freezer for 10 minutes.
Remove from freezer and spread softened coffee ice cream over the crust.  Return to the freezer until ready to add fudge layer.
In the mean time make the fudge layer.  Melt chocolate and butter in saucepan.  Add sugar, milk and salt.  Bring to a boil stirring continuously.
Lower heat and cook, stirring occasionally, until thickened.
Remove from heat, add vanilla and mix well.  Chill until cooled completely.
Spread over ice cream layer.  Return to freezer for 20 minutes.
Whip heavy cream, Kahlua & sugar until stiff peaks form.  Spread over top.  Freeze.
For best results, remove from freezer 15 minutes before serving.

This is out of this world!
