When you’re ready to bake, simply combine the refrigerated batter, fold in the rhubarb, sprinkle with the cinnamon-sugar topping, and bake as instructed. This way, you can enjoy a freshly baked dessert with minimal effort, making it just as delightful for busy weeknights!

Moist Sourdough Rhubarb Cake Recipe FAQs
What should I look for when selecting fresh rhubarb?
Absolutely! When choosing fresh rhubarb, look for stalks that are firm and have a vibrant color. Avoid any that are wilted or have dark spots all over, as these can indicate spoilage. The thinner stalks are often more tender, while thicker stalks tend to be a bit more fibrous.
How should I store my Moist Sourdough Rhubarb Cake?
To keep your cake fresh, store it in an airtight container at room temperature for up to 3 days. If you want to store it longer, you can refrigerate it for up to 5 days, but be aware it may lose some moisture. For the best results, I recommend freezing any leftovers instead!
Can I freeze this cake, and how should I do it?
Very! To freeze your Moist Sourdough Rhubarb Cake, wrap individual slices tightly in plastic wrap and place them in a freezer-safe bag. Be sure to label the bag with the date. It can be stored in the freezer for up to 3 months. When you’re ready to enjoy, simply thaw in the refrigerator overnight and warm it up in the microwave for about 15-20 seconds.
What if my cake comes out dry?
If your cake turns out dry, it might be due to overbaking or mixing the batter too much. To prevent this, make sure to keep an eye on it while baking and perform the toothpick test at the lower baking time. If you notice dryness after it’s baked, try adding a glaze or syrup for added moisture when serving!
Is this cake suitable for various dietary needs?
Of course! This Moist Sourdough Rhubarb Cake can easily accommodate dietary preferences. For a vegan version, simply replace the egg with a flax or chia egg. Additionally, you can substitute non-dairy milk and gluten-free flour as desired. If you have allergies, always check the ingredient labels to ensure they meet your needs.
Can I use frozen rhubarb, and how should I prep it?
Absolutely! You can use frozen rhubarb without thawing it first. Just chop it into ½-inch pieces and add it straight into the batter. This is a wonderful time-saver and allows you to enjoy your cake even when fresh rhubarb isn’t in season!
