Toffee Brownies Chewy Chocolate (Print Version)

# Ingredients:

01 - 5 tablespoons (71 grams) unsalted butter
02 - 3/4 cup (150 grams) granulated sugar
03 - 1/2 cup (100 grams) light brown sugar
04 - 2 large eggs plus 1 egg yolk, cold
05 - 1 teaspoon vanilla extract
06 - 1/3 cup (74 grams) vegetable oil
07 - 3/4 cup (75 grams) Dutch-process cocoa powder
08 - 1/2 cup (63 grams) all-purpose flour
09 - 1 tablespoon cornstarch
10 - 1/4 teaspoon fine sea salt
11 - 3/4 cup (128 grams) semisweet chocolate chips, divided
12 - 1 cup (170 grams) toffee bits, divided

# Instructions:

01 - Preheat the oven to 325°F. Line an 8 by 8-inch metal pan with parchment paper, leaving an overhang.
02 - In a large microwave-safe bowl, add the butter. Microwave for about 1 minute, or until the butter is melted. Whisk in the granulated sugar and light brown sugar, then let cool to just warm.
03 - Whisk in the eggs, egg yolk, and vanilla. Whisk vigorously for 30 seconds. Whisk in the vegetable oil and cocoa powder until smooth.
04 - Using a rubber spatula, stir in the all-purpose flour, cornstarch, and sea salt until combined. Stir in the chocolate chips and toffee bits, reserving a handful of each.
05 - Spread the brownie batter evenly into the prepared pan. Sprinkle with the reserved toffee bits and chocolate chips.
06 - 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. For less fudgy brownies, bake an additional 5-7 minutes, or until only melted chocolate attaches to the tester.
07 - Let the brownies cool completely before cutting and serving. Store in an airtight container at room temperature for up to 3 days or up to 5 days in the fridge.

# Notes:

01 - For a smoother, richer flavor, Dutch-process cocoa powder is recommended, though natural cocoa powder can be used instead.
02 - Use dark or bittersweet chocolate chips to balance sweetness if desired.
03 - Store-bought toffee bits are convenient, but homemade toffee bits can also be used.
04 - Serve brownies chilled for a fudgier texture.
