Fudgy Toffee Flourless Brownies Cooking Guide

Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your brownies will bake evenly and come out perfectly fudgy.
Step 2: Prepare the Baking Pan
Line a 9×9-inch baking pan with parchment paper, leaving some overhang on the sides. This will make it easier to lift the brownies out once they are baked.
Step 3: Melt Chocolate and Butter
In a large mixing bowl, combine the semi-sweet chocolate chips and unsalted butter. Microwave in 30-second intervals, stirring in between, until completely melted and smooth.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the cocoa powder, cornstarch, salt, and granulated sugar. This step ensures that all dry ingredients are well combined and ready to mix.
Step 5: Mix in Eggs and Vanilla
To the melted chocolate mixture, add the room temperature eggs and vanilla extract. Whisk until fully combined.
Step 6: Incorporate Dry Ingredients
Gradually add the dry ingredient mixture to the chocolate mixture, stirring until just combined. Be careful not to overmix; you want the brownies to remain fudgy.
Step 7: Fold in Toffee Bits
Using a spatula, gently fold in the Heath toffee bits, ensuring they are evenly distributed throughout the brownie batter.
Step 8: Bake
Pour the brownie batter into the prepared baking pan, spreading it evenly. Bake in your preheated oven for about 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
Step 9: Cool and Serve
Allow the brownies to cool completely in the pan on a wire rack. Once cooled, use the parchment overhang to lift the brownies out of the pan. Cut into squares and enjoy!
Substitutions by Category

- Chocolate: Use dark chocolate chips for a richer flavor.
- Butter: Coconut oil can be used as a dairy-free alternative.
- Cocoa Powder: Carob powder can be substituted for a different flavor profile.
- Toffee Bits: Chopped nuts or chocolate chunks can replace toffee bits for a different texture.
Don’t Do This
- Don’t overmix the batter once you add the dry ingredients; this can make the brownies tough.
- Avoid opening the oven door too early; this can affect the rising of your brownies.
- Don’t skip the cooling step; allowing the brownies to cool helps them set properly.

Your Questions, Answered
Can I use a different type of chocolate?
Absolutely! Feel free to use dark chocolate or even white chocolate chips if you prefer a different flavor. Just keep in mind that it may alter the overall taste of your brownies.
What if I don’t have cornstarch?
You can substitute cornstarch with an equal amount of arrowroot powder or potato starch. Alternatively, you can simply use an extra egg for binding.
Can I add more mix-ins?
Definitely! You can mix in nuts, chocolate chunks, or even dried fruit to customize your brownies to your liking.
Why did my brownies turn out cakey?
If your brownies are cakey, it could be due to overmixing the batter or baking them too long. Make sure to bake until just set and avoid overmixing once you add the dry ingredients.
