Preheat your oven to 350 degrees.

 

Line a large baking sheet (with sides) with parchment paper and pour your crackers out in an even layer. Set aside. 

 

In a medium saucepan over medium heat, melt your butter completely and then add the brown sugar, cinnamon and vanilla. 

 

Stir constantly until the butter is fully incorporated and comes to a rolling boil. Allow to cook, continuing to stir constantly, for 1-3 minutes until the mixture turns lighter in color and is smooth. 

 

Pour the mixture over your crackers and, using a rubber spoon or spatula, stir to coat all of the crackers well. Sprinkle them with salt and bake for 7-9 minutes. Stir them around again to be sure they are coated well. Allow to cool for 5 minutes and then remove the parchment paper from the pan. Allow to cool another 10 minutes and enjoy!
