If you have problems with your carrot cake being too crumbly, there are several different reasons why this could happen: 1. You’re using too much coconut oil. 2. The batter was dry as it didn’t contain enough liquid. 3. The batter contained too much flour. 4. The baking tins you used were too big for the amount of batter, resulting in an over-baked cake which is drier than it should be. 5. Your oven temperature was too high, resulting in an over-baked cake. If you’ve made a carrot cake and find it comes out crumbly, you can troubleshoot it by checking you used the correct amount of all the above ingredients!
