Preheat oven to 425°F. Line a large baking sheet with parchment paper.

Arrange the crackers, salted side down, in a single layer on the lined baking sheet. Set aside.

To a small saucepan over medium-high heat, add the butter and brown sugar. Bring the mixture to a boil, stirring constantly. Allow to boil for 3-5 minutes, or until butter is melted and sugar dissolved. Toffee needs to reach 270°F - 290°F and should darken and thicken.

Carefully pour the toffee mixture evenly over the crackers, spreading it to the edges if needed.
05 -
Bake for 3-5 minutes, or until the butter and sugar mixture begins to bubble.

Carefully remove from oven and immediately sprinkle chocolate chips on top. Allow to sit for about one minute until they start to soften and melt.

Using an offset spatula, spread the melted chocolate over the crackers.
08 -
Transfer to refrigerator for about an hour, or freezer for 30 minutes, until set.
