Ingredients
- 1 box brownie mix (18–20 oz)
- 2 large eggs
- ½ cup vegetable oil (or melted butter for richer flavor)
- Optional mix-ins: ½ cup chocolate chips, nuts, candies, or any favorites
Instructions
1. Prep the Baking Sheet
Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper or lightly grease it.
2. Make the Dough
In a large bowl, mix together the brownie mix, eggs, and oil.
Stir until a thick, cohesive dough forms—it will look more like cookie dough than brownie batter.
Fold in your mix-ins, such as chocolate chips.
3. Scoop the Cookies
Using a cookie scoop or tablespoon, drop rounded portions onto the baking sheet, spacing them 2 inches apart to allow for spreading.
4. Bake
Bake for 8–10 minutes.
The cookies are ready when:
- Edges look set
- Tops may appear slightly cracked
- Centers still look soft
Underbaking is the secret to a chewy center.
5. Cool and Serve
Let the cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
Variations
These cookies are endlessly customizable. Try:
For a richer chocolate hit
- Semi-sweet chocolate chips
- White chocolate chunks
- Cocoa nibs
For themed or festive cookies
- Peppermint chips
- M&M’s
- Chopped peanut butter cups
For added crunch
- Toasted pecans
- Walnuts
- Chopped hazelnuts
For flavor twists
- Coconut + butterscotch chips
- A swirl of caramel
- A sprinkle of flaky sea salt
Top freshly baked cookies with extra chocolate chips, nuts, or a drizzle of melted peanut butter for an elevated finish.
Tips for Perfect Brownie Mix Cookies
- Use melted butter instead of oil for deeper flavor.
- Add 1 teaspoon vanilla extract for extra warmth.
- Start checking at 8 minutes—slightly underbaked centers = maximum chewiness.
- Use a cookie scoop for evenly sized cookies.
- Mix in 1 tablespoon cocoa powder or instant espresso powder to boost the chocolate flavor.
- Roll dough balls in coarse sugar for a sparkly finish.
How to Store
