enough crackers to line a baking sheet.
1 cup unsalted butter. (2 sticks).
1 cup packed light brown sugar.
1/2 tsp vanilla extract.
1 cup semisweet chocolate chips.
1 cup marshmallows or coconut, optional.
1 cup nuts of your choice. (cashews, almonds, walnuts, pecans, peanuts)
1. Line a baking sheet with foil, making sure you have enough to create a tall rim around the pan. Line the pan with crackers, breaking up pieces if you have to, to fill in any cracks. Preheat the oven to 375F.
2. In a medium sized saucepan, melt the butter and brown sugar together over medium heat. Stir frequently until the mixture begins to boil. Once boiling, continue boiling for 3 minutes, stirring constantly. Remove from heat and add in vanilla. Pour caramel over crackers, and spread evenly with a silicone spatula. CAUTION! This mixture is very hot and will stick to your skin, causing a nasty burn. BE CAREFUL!
3. Put the baking sheet in the oven, reducing heat to 350F. Bake for 15 minutes, watching carefully that the caramel does not burn.
4. Remove from heat and cover with chocolate chips. Let stand 5 minutes until chocolate melts, and then spread evenly with a spatula. Sprinkle nuts or whatever toppings you desire. Let cool completely, and then break into pieces, storing in an airtight container.
