Toffee Brownies are chewy, rich, packed full of chocolate flavor, and studded throughout with toffee pieces. The perfect combination of decadent chocolate and crunchy, nutty toffee! Easy recipe, no mixer required.
Preheat the oven to 325°F. Line an 8 by 8-inch metal pan with parchment paper, leaving an overhang.
In a 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, salt, and baking soda 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. Do not overcook. 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.**
Notes
*You can use storebought toffee bits if needed, but I highly recommend using my Homemade Toffee Bits Recipe for best taste and texture.**Serve brownies chilled for an even fudgier texture!
