Make Caramel using ?

I found this recipe for some no bake Twix Bars and the most awesome thing (I think) is how you make the caramel.  Graham Crackers...yep...you heard me right you use sugar, butter and graham crackers.  It is amazing and tastes good too.  And because we are low sodium in my house, I used Unsalted Tops Saltine Crackers instead of Club crackers, and Unsalted Butter instead of margarine.  They are so easy, and surprise they do taste like a Twix candy bar.  If you decide to try the low sodium I don't think you would even notice. :)

Twix Bars

2 pkgs Unsalted Top Saltines {or cracker of choice}

Caramel Filling

1 cup Graham Crackers, crushed

3/4 cup Brown Sugar,packed

1/3 cup White Sugar

1/3 cup Milk

1/2 cup Unsalted Butter

Icing

2/3 cup Peanut Butter

1 cup Milk Chocolate Chips

Bars

Begin my putting a layer of Unsalted Tops Saltine Crackers in a pan.

In a saucepan on the stove, combine the caramel filling ingredients.

Bring to a boil, continue to stir and boil for approximately 5 minutes.  

The mixture will be caramel like and pull away from the sides of the pan.

Pour over the crackers, being very careful, the mixture is extremely hot.

Immediately top with another layer of crackers, pressing down slightly

Place in fridge to chill for at least 30 minutes.

Combine peanut butter and chocolate chips in small bowl. Microwave for 2 minutes, stir well and frost crackers.
