How to Make Rhubarb Cake
Preheat your oven to 350°F. Grease a 9×9 baking pan thoroughly, ensuring an easy release after baking. Setting a cozy atmosphere is key as you prepare this nostalgic treat!
Cream together the softened butter, brown sugar, and granulated sugar in a medium mixing bowl until light and fluffy. This usually takes about 2-3 minutes, filling your kitchen with that inviting aroma!
Beat in the large egg until fully incorporated, adding richness and binding the ingredients together beautifully.
Stir in the buttermilk and vanilla extract until the mixture is uniform. This step adds moisture and enhances the delightful flavor that will envelop your cake.
Mix in the baking soda, salt, and flour gradually until just combined. Don’t worry about a few lumps; they create a wonderfully textured cake!
Fold in the chopped rhubarb gently. As you add this vibrant vegetable, picture that burst of tartness waiting to delight your taste buds!
Transfer the cake batter to the prepared pan, spreading it into an even layer with a spatula. Make sure it’s smooth and inviting for the oven.
Combine the remaining sugar and cinnamon in a small bowl, then sprinkle it over the top of the cake evenly. This creates a lovely sweet crust that contrasts beautifully with the tart rhubarb.
Bake for 28-32 minutes or until a toothpick inserted into the center comes out clean. Keep an eye on it near the end for that perfect golden-brown finish!

Expert Tips for Rhubarb Cake
Choose Fresh Rhubarb: Make sure to use vibrant, firm rhubarb for the best flavor. Avoid any stalks that have wilted or become limp.
Butter Temperature Matters: Softened butter mixes better, creating a lighter cake. If you forgot to take it out of the fridge, quickly cut it into small cubes to soften faster!
Don’t Overmix: When combining the flour, baking soda, and salt, mix just until incorporated. Overmixing can lead to a dense cake instead of a lovely light texture!
Adjust Sweetness: If you prefer a sweeter cake, consider adding an extra tablespoon of granulated sugar to the batter. Taste the balance before adding topped sugar for the perfect finish.
Cooling Time: Allowing the cake to cool for at least 10 minutes helps it set and makes for neater slices. Patience is key in presenting this delightful rhubarb cake recipe!
Serving Suggestions: Serve with whipped cream or a scoop of ice cream to elevate this nostalgic dessert even further—it’s a crowd-pleaser!

Old Fashioned Rhubarb Cake Recipe FAQs
What should I look for when selecting rhubarb?
Absolutely! When choosing rhubarb, look for stalks that are firm, vibrant, and brightly colored. Avoid any that show signs of wilting or limpness. Dark green rhubarb might be more bitter than the pink or red varieties, so aim for those with a rosy hue for the best flavor!
How can I store leftover rhubarb cake?
The more the merrier! Keep your rhubarb cake covered at room temperature for up to 3 days. If you’d like to extend its freshness, wrap it tightly in plastic wrap and store it in the refrigerator for up to 5 days. This will help retain its moisture and keep those delightful flavors intact.
Can I freeze rhubarb cake?
Yes, you can! To freeze, first, let the cake cool completely. Then, slice it into individual portions, wrap each slice in plastic wrap, and place them in an airtight container or freezer bag. Label it with the date, and it will stay fresh for up to 3 months. When you’re ready to enjoy, simply thaw it in the fridge overnight or microwave it for a quick treat!
What if my rhubarb cake came out too dense?
If your cake turned out a bit dense, it could be due to overmixing the batter. It’s important to mix just until the ingredients are combined, as overmixing can lead to a dense texture. To troubleshoot, you can use a whisk to lightly combine the ingredients next time, and be sure your baking soda is fresh!
Is rhubarb safe for pets or people with allergies?
Great question! While rhubarb is safe for humans, it’s not suitable for pets, particularly dogs, as they can suffer from rhubarb poisoning due to the oxalic acid it contains. If you or anyone you are serving has allergies, always check for sensitivities, especially with ingredients like buttermilk or gluten in all-purpose flour.
What’s the best way to reheat leftover rhubarb cake?
For a deliciously fresh taste, you can reheat leftover slices in the microwave for 15-20 seconds, or warm them up in an oven at 350°F for about 10 minutes. This will revive the cake’s crust and ensure every bite feels just as delightful as when it was freshly baked!
