Cake is dry
Also searched as: crumbly cake, dry cake, cake too dry

In short: Usually baked too long. Sometimes it lacks sugar or fat, which hold on to moisture.
Picture it
Like a loaf left out uncovered overnight: the moisture is gone, leaving a crumbly shell.

Question 1
Did you stick exactly to the baking time?
All causes, by frequency
3
- Baked too long or too hot
Every extra minute evaporates water from the crumb.
Next time: Check earlier · The skewer may have moist crumbs, but no wet batter
- Too much flour
Measured cups often hold much more flour than you think.
Next time: Weigh the flour
- Sugar or fat reduced
Both hold water in the cake.
Next time: At most a quarter less sugar · A little yoghurt or oil in the batter
