Preheat oven to 350 degrees.

Line a baking sheet with parchment paper (or aluminum foil) and lightly spray with non-stick cooking spray.

Spread your crackers in a even layer on the baking sheet.

In a large pan on medium heat, melt the butter. Add the brown sugar and vanilla. Stir until brown sugar is dissolved.

Turn up the heat until the mixture begins boil. Stir continuously for about 3-4 minutes while the mixture gets bubbly and lighter in color. It will smell delicious!

Turn off the heat and quickly pour over the top of the crackers. Mix gently with a rubber spatula until all of the crackers are completely coated.

Sprinkle the kosher salt over the top of the crackers.

Bake for 8-10 minutes. Ovens vary and sugar burns easily, so keep a close eye on them to prevent burning.

Allow the crackers to cool. Then break into pieces. Serve immediately or store in an airtight container.
