Step 1

Preheat the oven to 400 degrees F and line a baking sheet with foil. Spray the foil with non-stick cooking spray.

Step 2

Place the crackers on the foil in a single layer and set aside.

Step 3

In a medium sauce pan, heat butter and sugar over medium heat.

Step 4

Allow the butter to melt, stirring constantly with a whisk. Bring the mixture to a boil for 3-5 minutes. Remove from heat and stir in the vanilla extract.

Step 5

Pour the butter mixture over the crackers and spread it out evenly. Bake for 5 minutes then remove from the oven.

Step 6

Let the crackers cool for 10 minutes.

Step 7

Once the crackers have cooled, melt the chocolate in the microwave, stirring every 20 seconds.

Step 8

Pour the chocolate over the crackers and use a spatula to spread it out evenly. Top with sprinkles.

Step 9

Chill the cracker mixture in the refrigerator for at least 1 hour or until hardened. Use a sharp knife to cut the saltine toffee into smaller pieces.
