Ingredients
Method
Make the Toffee
- Preheat the oven to 425°F and line a 9x13-inch baking dish with parchment paper.
- Lay the saltine crackers in an even layer in the bottom of the pan.
- In a medium saucepan over medium-high heat, melt 1/2 cup unsalted butter and 1/2 cup light brown sugar. Stir occasionally until it comes to a boil.
- Once boiling, reduce the heat to medium and let it boil for 4-5 minutes without stirring.
- Remove from heat and carefully pour the caramel mixture over the crackers, spreading it evenly.
- Bake for 4-5 minutes until just bubbly.
- Remove from the oven and sprinkle the chocolate chips on top. Let sit for a few minutes to soften.
- Spread the melted chocolate evenly across the toffee and sprinkle with sea salt if desired.
- Place toffee in the freezer while making the cookie dough.
Brown the Butter
- In a medium saucepan over medium heat, melt 1 cup unsalted butter while swirling continuously until it foams.
- Stir constantly for about 5 minutes until the milk solids turn golden brown and create a nutty aroma. Let cool slightly for 10 minutes.
Make the Dough
- In a large bowl, whisk together 2 1/2 cups of flour and 1 teaspoon of baking soda.
- Mix in brown butter, brown sugar, and granulated sugar until smooth.
- Beat in eggs and vanilla until no yellow streaks remain.
- Pour the wet mixture into the dry ingredients and stir until just combined.
- Chill the dough in the freezer for about 15 minutes.
Combine & Bake
- Remove the toffee from the freezer and chop it into small pieces.
- Stir the toffee into the cookie dough, reserving some to sprinkle on top.
- Cover with plastic wrap and chill for at least 2 hours or up to 3 days.
Bake
- Preheat oven to 350°F and line a baking sheet with parchment.
- Scoop dough into 2 tablespoons sized balls, placing them a few inches apart.
- Bake for 8-10 minutes until edges are golden and tops are just set.
- Top with reserved toffee bits and cool on a wire rack.
Notes
These cookies can be stored in an airtight container at room temperature for up to 5 days. For longer storage, freeze them for up to 3 months. Ensure your butter is not sizzling when mixed with sugars.
