Simple Rhubarb Cake Mix

Jump to Recipe

Our Grandma’s Rhubarb Cake recipe is a great way to enhance the sweetness of this fruit. This classic cake requires no boxed cake mix, making it easy to whip up without needing to run to the store. Rhubarb is an edible stalk that can be tart but can be cooked to bring out it’s sweetness.

Rhubarb season starts in the early spring, often in May before the farmer’s market even kicks off– it lasts until about June, but have no fear– rhubarb is very easy to freeze and enjoy all year long. Simply wash and cut into 1 inch pieces. No blanching required. Throw those pieces into a freezer bag. When you’re ready to enjoy, pull out a bag and thaw to make some delicious cake – any time of the year.
