How to Make Brownie Mix Cookies
These one-bowl cookies come together in just 20 minutes!
Step 1: Preheat & Prep
- Preheat your oven to 350°F (175°C).
- Line a baking sheet with parchment paper or lightly grease it.
Step 2: Make the Cookie Dough
- In a large mixing bowl, combine the brownie mix, eggs, vegetable oil, and water.
- Stir until a thick, sticky dough forms.
- Fold in chocolate chips or any other mix-ins you like.
Step 3: Scoop & Shape
- Use a cookie scoop or spoon to drop tablespoon-sized balls of dough onto the baking sheet, leaving 2 inches of space between each.
- If the dough is too sticky, chill it in the fridge for 15–20 minutes before scooping.
Step 4: Bake!
- Bake for 10–12 minutes, or until the edges are set but the centers are still soft.
- Let the cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
Step 5: Enjoy!
