Frequently Asked Questions

Can I use fresh rhubarb instead of frozen?

Yes, fresh rhubarb works perfectly in this recipe. Just make sure to wash and dice it properly before adding it to the cake. The baking time will remain the same, and using fresh rhubarb will give the cake a vibrant flavor and texture.

Is it necessary to grease the pan?

Yes, greasing the pan is important to prevent the cake from sticking. You can use butter or cooking spray to coat the pan evenly. This will ensure that when the cake is baked, it comes out smoothly without breaking apart.

Can I make this cake ahead of time?

Absolutely! This cake can be made ahead of time and stored in the refrigerator. Just allow it to cool completely before covering and refrigerating. It can also be frozen for up to 2 months; simply thaw in the refrigerator before serving.
