- More liquid-like due to extra eggs and melted butter/oil.
- Results in fudgy, chewy, or cakey textures.
- Usually contains cocoa powder and melted chocolate.
- Cookie Dough:
- Thicker and firmer because of more flour and less liquid.
- Holds its shape when baked instead of spreading.
- Usually contains solid fat (butter) and mix-ins like chocolate chips.
Benefit of Knowing the Difference:
✔ Helps when layering brownie and cookie dough.
✔ Prevents overmixing or uneven baking.
