Pre-heat oven to 350 degrees.
Line two baking sheets with tinfoil, and place Saltine crackers in a single layer.
Set a saucepan to medium-high and add sticks of butter.
Add brown sugar and white sugar.
Bring to a boil for just a minute.
Pour butter toffee mixture over the saltines.
Put the sheets in the oven for ten minutes. Rotate the pans at the 5-minute mark. They'll come out all brown and bubbly.
Cover the crackers with chocolate morsels.
Place sheets back in the oven for a couple of minutes -- just long enough to soften the chocolate.
Chop Nuts.
Take the sheets out of the oven, and with a spatula, spread the chocolate evenly over the saltines.
Sprinkle nuts over the chocolate.
Place the baking sheets in the fridge. Allow to cool for a few hours.
Remove from fridge. Peel the bark away from the tinfoil and break into pieces.
