How to Make Rhubarb Cake
-
Preheat your oven to 350°F, and grease a 9×9 baking pan to ensure a smooth release once baked. This step is crucial for achieving that perfect golden crust!

Cream together the softened butter, brown sugar, and granulated sugar in a medium mixing bowl. Mix until fluffy and well combined, roughly 2-3 minutes. This will create a delightful base for your rhubarb cake.
-
Beat in the large egg until fully incorporated, ensuring the mixture becomes light and airy. This adds richness and structure to your cake.
-
Stir in the buttermilk and vanilla extract until well mixed. This will give your cake its moist texture and delicious flavor.
-
Incorporate the dry ingredients—flour, baking soda, and salt—slowly into the wet mixture until just combined. Be careful not to overmix, or the cake may become dense; a few lumps are perfectly fine!
-
Fold in the chopped rhubarb gently, ensuring even distribution throughout the batter. You want those vibrant pieces to shine in every bite!
-
Transfer the cake batter to the prepared pan, spreading it evenly. This is where your rhubarb cake starts to take shape!

Expert Tips for Rhubarb Cake
-
Measure Carefully: Using the correct measurements for flour and sugar is crucial to achieve the perfect texture. Too much flour can lead to a dense cake.
-
Fresh Rhubarb: Opt for fresh rhubarb instead of frozen for better flavor and texture. If using frozen, ensure it’s fully thawed and well-drained.
-
Avoid Overmixing: When incorporating the dry ingredients, mix until just combined. Overmixing can result in a tough cake, so leave a few lumps.
-
Cool Properly: Allow the rhubarb cake to cool in the pan for a few minutes before transferring it to a wire rack. This prevents it from becoming gummy.
-
Customize Toppings: Feel free to experiment with toppings! Adding chopped nuts or a sprinkle of oats can add an extra layer of texture and flavor.
-
Storage Tips: Keep your leftover rhubarb cake in an airtight container at room temperature for up to three days, or refrigerate for longer freshness.

Old Fashioned Rhubarb Cake Recipe FAQs
What should I look for when selecting rhubarb?
When choosing rhubarb for your cake, look for firm stalks that are bright in color and free from blemishes. Avoid stalks that have dark spots or appear wilted, as these indicate overripeness or spoilage. Thicker stalks are typically more tender and flavorful, so feel free to compare to get the best quality!
How should I store leftover rhubarb cake?
To store your leftover rhubarb cake, place it in an airtight container at room temperature for up to 3 days if you plan to eat it quickly. If you want to keep it for longer, pop it in the fridge where it can last up to 7 days while retaining its flavor. Just make sure it’s well-sealed!
Can I freeze my rhubarb cake?
Absolutely! To freeze, slice the rhubarb cake and wrap each piece tightly in plastic wrap, then place them in a freezer-safe bag or container. This will protect it from freezer burn. Your cake can last for approximately 3 months in the freezer. When you’re ready to enjoy, simply thaw it overnight in the fridge or on the counter for a few hours.
What if my rhubarb cake turned out too dense?
If your cake came out denser than expected, it could be due to overmixing when incorporating the dry ingredients. Remember, it’s perfectly fine to have a few lumps! The next time, make sure you mix until just combined to keep that tender texture. Also, check that you’re measuring flour correctly; using a kitchen scale for accuracy can be a game changer!
Can I make this recipe allergen-friendly?
Yes, you can! For a gluten-free version of the rhubarb cake, substitute all-purpose flour with a 1:1 gluten-free flour blend. If you’re avoiding dairy, you can use a dairy-free milk combined with a teaspoon of vinegar to mimic buttermilk. Always check for ingredients that might cause allergies, especially when sharing with loved ones.
