Fudge Brownie Mix

Store in a cool, dry pantry. Once opened, keep in an airtight container to prevent moisture absorption. Unopened boxes keep for 12+ months; check the printed expiration date.

Use the exact liquid and fat ratios on the box for best texture—too much water makes them cake-like, too little makes them dry.

Don't overmix the batter; stir just until flour streaks disappear to keep brownies fudgy.

Slightly underbake (pull them out when a toothpick has a few moist crumbs) for maximum fudginess.

Let brownies cool completely in the pan before cutting for cleaner edges.

Adding extra ingredients (chocolate chips, nuts) without adjusting liquid, which can throw off the bake.

Overbaking due to oven temperature variance—use an oven thermometer if your brownies often turn out cakey.

Forgetting that mix ratios are calibrated; skipping or doubling ingredients ruins the texture.

Using melted butter instead of oil if the box calls for oil, which changes moisture and density.
