Though I’ve published more than 50 (!!!) brownie recipes in the past 15 years, I still find inspiration to develop new flavors.
Little did I know just how popular this new recipe would be!
I originally published this Toffee Brownies recipe in 2013, but it needed a overhaul. So, I went to the kitchen! After a few tweaks, I sent a batch to Joe’s workplace, only to receive an empty pan with unanimous feedback demanding another round of “taste testing.”
I’m not exaggerating – I’ve made these brownies over 10 times since creating the recipe because people keep asking me to make them.
And I don’t mind one bit. These brownies are everything I want in a dessert!
They’re quick and easy to make. They’re chocolate-forward (a definite win in my book). They’re rich and chewy with crunchy toffee throughout – aka texture heaven.
Give these brownies a try the next time you need a chocolate fix (so, right now, right? 😉). You won’t be disappointed!
Sprinkle of Science
How to Make Toffee Brownies
The Chocolate Chips
Semi-sweet is my favorite, but feel free to fold in any variety of chocolate chips you prefer. Whatever you do, don’t skip the chocolate chips! They help to develop that shiny crust on top of brownies. Learn more about the shiny crust on brownies here.
The Toffee
You can use store-bought or homemade! For extra gourmet brownies, use my Homemade Toffee Bits recipe. You can also use Heath brand English toffee bits (as pictured below), available in supermarkets by the chocolate chips in the baking aisle.
Butter + Oil
- With any cocoa powder-based brownie recipe, we need quite a bit of fat to prevent the cocoa powder from drying the brownies out and making them crumbly.
- These brownies use a combination of melted butter and oil for the best balance of taste and texture.
- I typically use vegetable oil, but any flavorless oil should work – just make sure your oil is fresh to avoid a rancid flavor.
- Check out my side-by-side baking experiments comparing Butter vs. Oil in Baking here.
Why is There Cornstarch in Brownies?
I have found that adding 1 tablespoon of cornstarch makes brownies thick and chewy, like box mix brownies, and improves the shiny crust on top – so don’t skip this ingredient. Learn more about that shiny crust on the top of brownies here.
The Sugar
We’re using a combination of granulated sugar and light brown sugar in this Toffee Brownie recipe. This creates a flavorful brownie with plenty of moisture, without adding too much moisture. It also complements the caramelized toasty flavors of the toffee perfectly.
Can I Reduce the Sugar in These Brownies?
- Don’t reduce the amount of sugar in Toffee Brownies unless you want dry and crumbly brownies.
- Reducing the sugar will also result in a dull (not shiny) crust.
- The sweetness will mellow as the brownies cool and set.
- If you’re worried these brownies will be too sweet for your preference, simply use dark or bittersweet chocolate chips to help balance the sweetness without ruining the texture of the brownies.
- Learn more about sugar’s role in baking brownies here (spoiler alert: sugar does so much more than just sweetening!)
What’s The Best Pan for Baking Brownies?
I highly recommend using a light-colored metal 8×8-inch baking pan like this one, lined with foil or parchment paper. Do not use glass, silicone, or ceramic pans for baking brownies. Learn why in my Glass vs. Metal Baking Pans article here.
Can I Double This Toffee Brownie Recipe?
Yes – simply double all ingredients and bake in a light-colored metal 9×13 metal pan, adding a few minutes to the bake time.
How to Cut Toffee Brownies for Clean Slices
For perfect slices, allow brownies to cool fully (chilled is even better!). Use a sharp knife and run it under hot water, carefully wiping it off in between each cut.
How to Store Toffee Brownies?
Toffee Brownies taste best the day they are baked but can be stored in an airtight container for up to 3 days at room temperature or up to 5 days in the fridge. When chilled, they become even more fudgy!
Can You Freeze Toffee Brownies?
Yes! Brownies freeze beautifully. Freeze the whole slab or individual slices by wrapping in plastic wrap and storing inside a freezer bag or an airtight container for up to three months. Thaw overnight in the fridge or for a couple of hours at room temperature before serving.

Ingredients
- 5 tablespoons (71 grams) unsalted butter
- 3/4 cup (150 grams) granulated sugar
- 1/2 cup (100 grams) light brown sugar
- 2 large eggs plus 1 egg yolk, cold
- 1 teaspoon vanilla extract
- 1/3 cup (74 grams) vegetable oil
- 3/4 cup (75 grams) Dutch-process cocoa powder1
- 1/2 cup (63 grams) all-purpose flour
- 1 tablespoon cornstarch
- 1/4 teaspoon fine sea salt
- 3/4 cup (128 grams) semisweet chocolate chips2, divided
- 1 cup (170 grams)
toffee bits3, divided
Instructions
- Preheat the oven to 325°F. Line an 8 by 8-inch metal pan with parchment paper, leaving an overhang.
- In a large microwave-safe bowl, add the butter. Microwave for about 1 minute, or until the butter is melted. Whisk in the sugars then let cool to just warm. Whisk in the eggs, egg yolk, and vanilla. Whisk vigorously for 30 seconds. Whisk in the oil and cocoa powder.
- Using a rubber spatula, stir in the flour, cornstarch, and salt until combined. Stir in the chocolate chips and toffee bits, reserving a handful of each.
- Spread the brownie batter evenly into the prepared pan. Sprinkle with extra toffee bits and chocolate chips. Place in the oven and bake for 30 minutes, or until the brownies are set and a cake tester inserted into the center has moist crumbs attached. If you prefer a less fudgy brownie, bake an additional 5-7 minutes, or until cake tester inserted into the center has only melted chocolate attached. Let cool completely before cutting and serving.
- Brownies can be stored in an airtight container at room temperature for up to 3 days at room temperature or up to 5 days in the fridge.4
Recipe Notes

I served this for dessert at my weekly family dinner. Everyone enjoyed them. I had to make my own toffee bits which was surprisingly easy and the recipe itself was easy too. I am silly but enjoy a plain brown best of all but these were lovely too.
Peep that chewy, oooey, chocolatey goodness! So glad I took the time to make my own toffee chips, they made the entire recipe (and they were easy too!) Hubby and coworkers loved these and they’ll be on repeat in my house for a while
These were so delicious and so easy to make. Didn’t even have to take out my mixer! Better cold and easier to slice, for sure.
Fudgy, chocolatey, rich! Came together quickly. Yum
This was simple to make and super yummy to eat. Definitely will be making again and soon!! Grandsons and all the kids will be here for Mother’s Day so this will be a hit! Everyone loves brownies
Wow! These are super fudgy! Just how I like my brownies. Loved the addition of the toffee bits. Very easy to make! I will definitely make again!
I used bittersweet chocolate in place of some of the chocolate chips since I don’t like things too sweet, but I would recommend sticking with semisweet since the chocolate flavor ended up a bit out-of-balance for my taste. Or maybe I need to experiment with brands of cocoa powder (it was dutch processed, but even with that flavor can vary between brands). They did bake and cut well.
These toffee chocolate chip brownies are simply devine and the taste is amazing!
Fabulous brownie. Perfect texture, nice and moist, chewy and cuts beautifully!
This brownie was a hit! Friends were asking for the recipe right away! I doubled the batch, so baking took longer, they were thicker than I think the original recipe made. I will be making these again!
These brownies are simple, take one bowl, and are delicious. Plus they look beautiful! Everything you could ask for.
Uhhhhg, these are divine! Like, I’m-trying-not-to-eat-the-whole-dang-pan kinda good. Easy to make, great gooey texture, the flavor is incredible. I used the Dutch processed cocoa since I love chocolate. I’m at a high altitude and only needed to increase the baking time.
