Seriously, just make 2 batches.
1 to 1.5 sleeves salted Saltine crackers
1 cup brown sugar
1 cup butter or margarine
3 cups chocolate chips
1 cup creamy peanut butter, melted
1 cup candy and/or sprinkles
Preheat oven to 400F degrees. Line a large cookie sheet with parchment paper, making sure it comes up all sides of the pan.
While you melt the butter and sugar together on medium heat, spread the crackers in a single layer across the entire cookie sheet. Just as the butter and sugar begin to boil, leave it alone without stirring for 3-4 minutes to make the toffee. Then pour the boiling mixture over the crackers. Bake for 5 minutes while you melt the peanut butter.
When toffee is done, remove from oven and allow it to settle (stop bubbling) before spreading the peanut butter over it. Sprinkle with chocolate chips, then pop back in the oven for a minute or two to melt them. Smooth the chocolate layer, add candy and sprinkles, and freeze for an hour or two to set the toffee. Then break into pieces and let the addiction begin!
