How to Make Toffee Cookie Bars Recipe
Step 1: Prep Your Pan and Oven
Start by preheating your oven to 375 degrees Fahrenheit and lining a 9×13-inch baking dish with parchment paper. This simple step ensures your cookie bars don’t stick and will come out in perfectly even squares.
Step 2: Cream the Butter and Sugars
Using a standing mixer, cream together the softened butter, light brown sugar, granulated sugar, egg, and vanilla extract until you get a smooth, fluffy mixture. This step is key to incorporating air into your dough, making those bars soft and tender.
Step 3: Mix the Dry Ingredients
In a separate large bowl, whisk together the flour, baking soda, baking powder, and kosher salt. Whisking ensures even distribution so your bars rise just right and have a great texture.
Step 4: Combine Wet and Dry
Gradually add the dry ingredients into the wet mixture, whisking gently until just combined. Overmixing here can make the bars tough, so take it slow and steady for perfect results.
Step 5: Fold in Your Flavor Bombs
Carefully fold in ¾ cup of espresso chips, ¾ cup of semi-sweet chocolate chips, and ¾ cup of Heath toffee bits. This is where the magic happens — all that chocolate-y, toffee crunch and subtle espresso flavor are melded right into the dough.
Step 6: Press the Dough and Add Toppings
Press the cookie dough evenly into your prepared baking dish. Then, sprinkle the remaining espresso chips, semi-sweet chocolate chips, and toffee bits generously over the top to create an irresistible, textured finish.
Step 7: Bake and Cool
Bake your bars for 20 to 25 minutes, just until the edges turn a lovely light brown. Allow them to cool completely in the pan before slicing — this step is essential for clean cuts and the bars to set perfectly.
How to Serve Toffee Cookie Bars Recipe

Garnishes
To elevate these bars, consider drizzling a simple chocolate ganache made with semi-sweet chocolate chips and heavy whipping cream over the top. A light sprinkle of sea salt right after baking also beautifully enhances the toffee’s caramel notes.
Side Dishes
These bars pair wonderfully with a scoop of vanilla ice cream or alongside a steaming cup of coffee or espresso to complement the espresso chips embedded within. A dollop of fresh whipped cream adds a soft and airy touch.
Creative Ways to Present
For parties or gifting, try stacking these bars between layers of parchment paper in a decorative tin or box. You can also cut them into smaller bouchée-sized squares for elegant bite-sized treats at gatherings.
Make Ahead and Storage
Storing Leftovers
Store leftover Toffee Cookie Bars in an airtight container at room temperature for up to 5 days. This keeps them fresh, chewy, and just as delicious as day one.
Freezing
These bars freeze well! Wrap them tightly in plastic wrap, then place in a freezer-safe container. Freeze for up to 3 months. When ready to enjoy, thaw at room temperature.
Reheating
For a warm indulgence, gently reheat bars in the microwave for 10-15 seconds or in a low oven until softened. This brings back that freshly baked vibe with melty chocolate and toffee crunch.
FAQs
Can I substitute the espresso chips for something else?
Absolutely! If you’re not a fan of espresso, you can swap the espresso chips for additional chocolate chips or chopped nuts for a different but equally tasty twist.
What if I don’t have Heath Bits O’ Brickle Toffee?
If Heath Bits are unavailable, chopped toffee candy or even some crunchy caramel bits work nicely as substitutes to maintain that delightful toffee crunch.
Can I use salted butter instead of unsalted?
Yes, you can use salted butter, but be mindful and reduce or omit the added kosher salt to keep the flavor balanced and avoid oversalting.
How thick will the cookie bars be in a 9×13 pan?
Pressing the dough evenly yields bars about 1 inch thick—perfect for holding all those mix-ins without turning cakey or too thin.
