Fudgy Brownie Mix Cookies

April 13, 2026

The ultimate hack for rich, chocolatey cookies with a crackly top and a chewy, brownie-like center.
Prep time: 10 minutes
Bake time: 10 minutes
Yields: Approx. 24 cookies

Ingredients

1 box (18 oz) Premium Brownie Mix (Chocolate Fudge works best)
1/4 cup All-purpose flour (this provides the structure needed for a cookie)
2 Large eggs
1/3 cup Vegetable oil (or melted butter for a richer flavor)
1 cup Semi-sweet chocolate chips (optional, for extra decadence)
A pinch of Flaky sea salt (for topping)

Instructions

1. Preheat and Prepare
Preheat your oven to 175°C (350°F). Line two large baking sheets with parchment paper or silicone baking mats to prevent sticking.
2. Mix the Dough
In a large bowl, combine the brownie mix and the flour. Add the eggs and oil. Stir by hand until the dough is thick, smooth, and shiny.
Note: The dough will be much thicker than regular brownie batter—this is exactly what you want! Fold in the chocolate chips at this stage if using.
3. Scoop and Space
Using a small cookie scoop or a tablespoon, drop rounded mounds of dough onto the prepared baking sheets. Space them about 2 inches (5 cm) apart, as they will spread slightly.
4. The Bake
Bake for 9–11 minutes.
The Secret: Do not overbake! The cookies should look slightly underdone and soft in the middle when you pull them out. They will firm up as they cool.
5. Cool and Finish
Let the cookies rest on the baking sheet for at least 5 minutes before moving them to a wire rack. While they are still warm, sprinkle a tiny bit of flaky sea salt on top to balance the sweetness.
Pro Tips for the Best Results
Chill the Dough: If the dough feels too sticky to handle, pop it in the fridge for 20 minutes before scooping.
Variations: You can swap the chocolate chips for white chocolate, chopped walnuts, or even a swirl of peanut butter on top before baking.
The Texture: These cookies stay soft and chewy for days if stored in an airtight container at room temperature.
