Flat cookies, cakey brownies, a sunken loaf, tough pancakes: the usual causes and what to change next time.
Cookies
Spread thin and flat
- Likely causes:
- Butter too soft or melted; too little flour; dough put on a warm sheet; oven not fully hot.
- Next time:
- Use softened, not warm, butter; measure flour carefully; chill the dough 30 minutes; cool sheets between batches.
Puffy and cakey
- Likely causes:
- Too much flour (scooped cups); too much creaming or too many eggs.
- Next time:
- Spoon and level the flour, or weigh it; cream just until light.
Dark or burnt bottoms
- Likely causes:
- Dark baking sheet; rack too low; oven runs hot.
- Next time:
- Light sheet lined with parchment, middle rack, check your oven with a thermometer (Oven and Pans).
Dry and hard
- Likely causes:
- Overbaked, or too much flour.
- Next time:
- Take them out while the centers still look soft.
Uneven batch
- Likely causes:
- Different-sized scoops; hot spots in the oven.
- Next time:
- Use a scoop or tablespoon; turn the sheet halfway.

Brownies and bars
Cakey instead of fudgy
- Likely causes:
- Overbaked; too much flour; too much beating after the flour went in.
- Next time:
- Pull them when a toothpick shows moist crumbs; fold the flour in gently.
No shiny, crackly top
- Likely causes:
- Eggs and sugar not beaten enough.
- Next time:
- Beat the eggs and sugar hard for a minute, as the Fudgy Brownies tip says.
Dry edges, raw middle
- Likely causes:
- Glass or dark pan; the recipe's full batter in a smaller pan, so it's deeper.
- Next time:
- Use a light metal pan, or lower the oven by 25°F (15°C) and bake longer (pan size).
Crumble when cut
- Likely causes:
- Cut while warm.
- Next time:
- Cool completely in the pan first.

Quick breads and muffins
Sank in the middle
- Likely causes:
- Underbaked; too much baking soda or powder; oven door opened too early.
- Next time:
- Check doneness with a skewer, not the clock; measure leaveners with level spoons.
Tough, with tunnels and peaked tops
- Likely causes:
- Overmixed after the flour went in.
- Next time:
- Stir only until no dry flour shows (muffin method).
Gummy streak near the bottom
- Likely causes:
- Underbaked, or too much wet ingredient (very big bananas).
- Next time:
- Bake until a skewer is clean; measure mashed banana if your bananas are large.
Dark top, raw center
- Likely causes:
- Oven too hot, or a dark pan.
- Next time:
- Lay foil loosely over the top once it's brown, as in the Banana Bread tip.
Dense and heavy
- Likely causes:
- Old leavener; too much flour.
- Next time:
- Test your baking soda and powder; weigh the flour.

Pancakes
Flat and dense
- Likely causes:
- Old baking powder; overmixed batter; batter left standing a long time.
- Next time:
- Test the baking powder; stir until just combined; cook within about 15 minutes.
Tough or rubbery
- Likely causes:
- Overmixed.
- Next time:
- Lumpy batter is right.
Burnt outside, raw inside
- Likely causes:
- Pan too hot.
- Next time:
- Medium heat; the first pancake is a test.
Pale and greasy
- Likely causes:
- Pan not hot enough, or too much butter in the pan.
- Next time:
- Heat the pan longer; brush on a thin layer of butter.
