1 10" pie crust
1 stick (8 Tbsp) salted butter
1 14 oz can sweetened condensed milk
Now, in one of these measuring cups, not the glass kind: 
1 Cup of each:
***measure pretzels and graham crackers after crushing***
Crushed pretzels (any shape, but crush to 1/2" or smaller pieces)
Crushed honey Graham crackers (some larger pieces, not all dust)
Chocolate chips (your choice of sweetness)
Caramel bits
Shredded coconut (sweetened or not, I've used both; for more coconut flavor, use sweetened- for less, use unsweetened)
Finely chopped pecans (the kind for pecan cookies- it will say that on the package)
1. Start with a cold oven, and pre-bake empty pie crust at 375 for 10 minutes. Remove from oven and let crust cool on a rack while making filling.
2. Melt butter in a microwave-safe container.
3. In a very large bowl, combine butter and condensed milk.
4. Add the rest of the ingredients and combine as thoroughly as possible - it's a very chunky mix!
5. When you're satisfied the ingredients are mixed well, pour (dump) it into the cooled pie crust and even out the spread of the filling across the crust.
6. Bake on the center rack of your already preheated oven at 375 (like the crust) for 30-35 minutes and remove promptly to the cooling rack.
The top should look very lightly browned. It will continue cooking (and weirdly: browning! IDK, but it does!) while it cools for at least 30 minutes. Overcooking will cause the pie to be dry inside.
Good alone, with whipped cream, or a dollop of vanilla ice cream.
A cup of coffee or a HUGE glass of milk is recommended.
Recommended for nearly all holiday gatherings (maybe not a large group of diabetics or a Weight Watcher's meeting - yes, they are different things).
HAPPY HOLIDAY'S, WONDERFULS!
