Cake Troubleshooting Guide

If you’ve ever pulled a cake out of the oven and thought “that’s not quite right”, you’re definitely not alone. Cakes can be affected by even small changes, and even when you follow a recipe carefully, things don’t always go to plan – we’ve all been there!

The good news is that most cake problems come down to a few common causes. Once you know what to look for, they’re easy to fix and your results become much more reliable.

If you’re looking for a broader guide covering common baking problems across cakes, cookies and more, I’ve shared that here.

Why didn’t my cake rise?

If your cake is flat or lower than expected, it usually means it has lost its lift somewhere along the way.

This can happen if:

• your baking powder or baking soda isn’t fresh
• the oven wasn’t fully preheated
• the mixture sat too long before baking
• the batter was overmixed after adding flour
• ingredients were too cold

What to do next time:
Check your raising agents are fresh, preheat your oven properly, and get the mixture into the oven as soon as it’s ready. Room temperature ingredients also make a difference.

Why did my cake sink in the middle?

A sunken centre usually means the cake didn’t fully set before it was removed from the oven.

This can happen if:

• the centre was slightly underbaked
• the oven door was opened too early
• too much raising agent was used
• the batter was overmixed
• the tin size was too small or too deep

What to do next time:
Bake until the centre springs back lightly when touched, avoid opening the oven too early, and measure carefully.

Why is my cake dense or heavy?

If your cake feels heavy rather than light, it usually comes down to mixing or measuring.

This can happen if:

• too much flour was added
• the batter was overmixed
• butter and sugar weren’t creamed enough
• there wasn’t quite enough raising agent

What to do next time:
Measure flour carefully, cream butter and sugar until light and fluffy, and mix gently once the flour is added.

This is especially important in recipes like my Grandma’s Vanilla Wonder Cake, where a light texture makes all the difference.

Why is my cake dry?

Dry cakes are usually caused by a small imbalance or baking slightly too long.

This can happen if:

• it was left in the oven even a few minutes too long
• the oven runs a little hot
• too much flour was added
• the tin was larger than expected
• there wasn’t enough fat or liquid

What to do next time:
Check your cake a few minutes before the suggested time, use the correct tin size, and measure carefully.

Why is my cake wet or gummy in the middle?

If the centre feels sticky or undercooked, it hasn’t fully set.

This can happen if:

• the cake hasn’t baked long enough
• the butter and sugar weren’t creamed properly
• the oven is too hot, so the outside sets before the middle
• there is too much liquid or sugar
• the cake was cut while still hot

What to do next time:
Bake until the centre is set, test with a skewer, and allow the cake to cool before slicing.

Why did my cake dome or crack on top?

A domed or cracked top usually comes down to heat.

This can happen if:

• the oven is too hot
• the outside sets too quickly while the inside continues to rise
• the tin is too small

What to do next time:
Bake at the correct temperature, place your cake on the centre rack, and use the recommended tin size.

Why is my cake burnt on the outside but raw inside?

When the outside cooks too quickly, the centre doesn’t get enough time.

This can happen if:

• the oven is too hot
• the heat is too strong from above
• the cake is too deep in the tin
• dark tins absorb more heat
• the rack is too high

What to do next time:
Bake on a centre rack and cover loosely with foil if the top is colouring too quickly.

Why is my cake sticking to the tin?

This usually comes down to how the tin was prepared or when it was removed from the oven.

This can happen if:

• the tin wasn’t greased or lined properly
• the cake was removed too soon
• the cake is still very soft

What to do next time:
Grease and line where needed, allow the cake to cool slightly, and run a knife around the edge before turning out.

Why is my cake greasy or oily?

If the texture feels oily, it usually means something is slightly out of balance

This can happen if:

• there is too much fat
• the cake is underbaked
• there isn’t enough support from the flour or eggs

What to do next time:
Follow the recipe carefully and bake until fully set so the fat is properly absorbed.

Why did my mixture curdle or split?

This is very common, especially in butter-based cakes.

This can happen if:

• ingredients were too cold
• eggs were added too quickly
• the mixture wasn’t fully combined between additions

What to do next time:
Use room temperature ingredients and add eggs gradually. If it starts to curdle, add a spoonful of the flour from the recipe and mix gently.

Why didn’t my cake turn out like the photo?

Even small differences can change the final result.

This can happen if:

• ingredients were measured differently
• substitutions were made
• oven temperature varies
• a different tin size was used

What to do next time:
Follow the recipe as written the first time, measure carefully, and use the suggested equipment.

A few extra tips that make a big difference

• Always preheat your oven properly. Starting in a cold oven can affect how your cake rises
• Measure ingredients carefully, especially flour. Even a little extra can change the texture
• Use the correct tin size. This affects how evenly your cake cooks and how long it needs
• Don’t rush cooling time. Your cake continues to set as it cools
• Lighter coloured tins are great for softer cakes and longer bakes, while darker tins can brown the outside more quickly
• Bake on the centre rack so your cake cooks evenly from top to bottom
• Try not to overfill your tins. About two-thirds full is ideal
• If your cake is browning too quickly, loosely cover the top with foil and continue cooking
• Every oven is a little different. If something feels off, it’s worth getting to know how yours runs

Small details really do matter, and often it’s just one small tweak that makes all the difference.

If something hasn’t turned out quite right, chances are it’s one small thing. Once you spot it, it’s easy to fix next time.

And don’t forget – icing can fix a multitude of sins!
