Place butter crackers in a food processor and blend until they are a fine, sandy texture. Transfer to a small mixing bowl.
3. Step
Add egg and melted butter to the crumbled crackers. Stir until crumbs become a clumpy, wet sand texture. Place the cracker mixture in the base of a 9-inch (23-inch) pie dish to create the crust.
4. Step
Use a measuring cup to smooth the surface. Once the surface is smooth, use a fork to prick the base and sides of the crust.
5. Step
Bake for 10 minutes. Remove from oven and let cool for 10 minutes.
6. Step
Mash russet potatoes in a large mixing bowl. Once thoroughly mashed, add butter, ¼ cup(60 gram) sour cream, milk, salt and pepper and mix together with large spoon or spatula.
7. Step

8. Step
Cover mashed potatoes with a layer of cheddar cheese, making sure to save some for the top.
9. Step
Spread the other half of mashed potatoes over the cheese layer. Sprinkle bacon bits and remaining cheese over the top.
