Brownie Mix Cookies

The perfect mashup of fudgy brownies and chewy cookies—ready in just 20 minutes! These decadent treats are rich, chocolatey, and foolproof thanks to brownie mix.


Ingredients (Makes ~18 cookies)

  • 1 (18 oz) box brownie mix (standard size)
  • ¼ cup (30g) all-purpose flour (helps thicken the dough)
  • 2 large eggs
  • ¼ cup (60ml) vegetable oil (or melted butter for richer flavor)
  • 2 tbsp water
  • ½ tsp vanilla extract
  • ½ cup (90g) chocolate chips (optional, but highly recommended!)

(Optional add-ins: chopped nuts, M&M’s, or a sprinkle of sea salt!)


Step-by-Step Instructions

1. Prep & Mix

  1. Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.
  2. In a bowl, stir together:
  • Brownie mix + flour (whisk first to remove lumps)
  • Eggs, oil, water, vanilla
    → Mix until thick and glossy (like brownie batter).
  1. Fold in chocolate chips.

2. Scoop & Bake

  1. Drop 1-tbsp portions of dough onto the sheet (2 inches apart).
  2. Bake 8-10 mins until edges are set but centers look slightly underdone.
    (They’ll firm up as they cool!)

3. Cool & Devour

  • Let rest 5 mins on the sheet, then transfer to a rack.
  • Enjoy warm with a glass of milk!

FAQs & Pro Tips

Q: Can I use cookie mix instead of brownie mix?

⚠️ No—brownie mix gives these their fudgy texture! Cookie mix will yield different results.

Q: Why are my cookies flat?

➡️ Possible causes:

  • Too much oil (measure carefully)
  • Overmixed dough (just stir until combined)
  • Hot baking sheet (let it cool between batches)

Q: Can I make these without eggs?

Yes! Use 2 tbsp applesauce + 1 tsp baking powder per egg.

Q: How to store leftovers?

  • Room temp: 3 days in an airtight container.
  • Freeze: Up to 1 month (thaw at room temp).

Q: Can I use melted butter instead of oil?

Yes! Butter adds richness, but oil keeps them chewier longer.
