⁉️ FAQ

Do you have questions about this recipe? Here are the answers to the most commonly asked questions.

Why are room temperature eggs better?

Room temperature eggs mix into the batter better and make a more tender cake.

Why did my cake stick to the bundt pan?

Bundt pans are tricky. Every nook and cranny of the interior of the bundt pan has to be greased or the cake will stick.

What is the difference between lime and key lime?

Key limes are smaller and more mellow than standard limes. This mellowness is why key lime is so popular in baked goods.
