Ingredients
To create this delightful Rhubarb Cake, you’ll need the following ingredients:
For the Batter
- 1/2 cup half and half, cream, or buttermilk
- 1 tsp lemon juice
- 1/2 cup unsalted butter at room temperature
- 1 cup granulated sugar plus 2 tsp for sprinkling
- 1 large egg, at room temperature
- 1 1/2 tsp vanilla extract
- 2 cups all-purpose flour, saving out 1 Tbsp to toss with rhubarb
- 2 tsp baking powder
- 1 tsp salt
- 2 cups thinly sliced rhubarb
How to Make Rhubarb Cake
Step 1: Preheat the Oven
Preheat your oven to 350°F. Lightly butter a 9×9 square baking pan. If desired, line the pan with parchment paper, allowing overhanging edges for easy removal after baking.
Step 2: Prepare the Buttermilk Mixture
Stir the lemon juice into the half and half (or cream or buttermilk) and set aside. This will add a nice tang to your cake.
Step 3: Cream Butter and Sugar
In a stand mixer or using electric beaters, cream together the soft butter and sugar until fluffy and pale yellow. Add the egg and vanilla extract, mixing well while scraping down the bowl when needed.
Step 4: Toss Rhubarb with Flour
Take 1 tablespoon of flour from your total amount and toss it with the sliced rhubarb in a small bowl. This helps prevent clumping in the cake batter.
Step 5: Mix Dry Ingredients
In another mixing bowl, whisk together the remaining flour, baking powder, and salt until evenly combined.
Step 6: Combine Wet and Dry Ingredients
Add half of the dry flour mixture to your butter mixture. Blend until just combined. Then add all of your buttermilk mixture and blend again. Finally, add the rest of the flour mixture gently until just incorporated. Fold in the floured rhubarb carefully without overmixing; note that your batter will be thick.
Step 7: Bake Your Cake
Spread the batter evenly into your prepared pan. Sprinkle a little sugar on top before placing it into the oven. Bake for about 40-45 minutes until golden brown. A toothpick inserted in the center should come out clean or with moist crumbs.
Step 8: Cool Before Serving
Allow your cake to cool slightly before cutting it into squares. Enjoy your homemade Rhubarb Cake warm or at room temperature!

How to Perfect Rhubarb Cake
To make sure your Rhubarb Cake turns out perfectly every time, consider these helpful tips.
- Use fresh rhubarb: Fresh rhubarb will provide the best flavor and texture. Avoid using wilted or overly soft stalks.
- Check oven temperature: Make sure your oven is calibrated correctly. An inaccurate temperature can lead to uneven baking.
- Avoid overmixing: Mix just until combined to keep the cake light and fluffy. Overmixing can make it dense.
- Cool before cutting: Allow the cake to cool slightly before slicing. This helps maintain its structure and prevents crumbling.
- Experiment with spices: Add spices like nutmeg or ginger for an extra flavor boost that pairs well with rhubarb.
- Store properly: Keep any leftovers in an airtight container at room temperature for up to three days, or refrigerate for longer freshness.
Best Side Dishes for Rhubarb Cake
Rhubarb Cake pairs wonderfully with several side dishes that can elevate your dessert experience. Here are some fantastic options:
- Greek Yogurt: A dollop of creamy Greek yogurt adds tanginess and protein, making your dessert feel more complete.
- Fruit Salad: A fresh fruit salad brings brightness and contrasts nicely with the sweetness of the cake.
- Cheese Plate: Pair slices with a selection of cheeses, such as goat cheese or brie, for a savory contrast.
- Granola Parfait: Layer granola, yogurt, and berries in a glass for a beautiful presentation and added crunch.
- Coffee Ice Cream: The rich flavors of coffee ice cream pair perfectly with the tartness of rhubarb, creating a delightful combination.
- Caramel Sauce: Drizzle warm caramel sauce over each slice for an indulgent treat that enhances its sweetness.
- Nuts: Serve alongside toasted nuts like almonds or pecans for added texture and flavor contrast.
- Chocolate Sauce: A drizzle of chocolate sauce transforms this simple dessert into an elegant delight perfect for special occasions.
Common Mistakes to Avoid
When making Rhubarb Cake, it’s easy to overlook some key steps. Avoid these common mistakes to ensure your cake turns out perfectly every time.
-
Not preparing the rhubarb properly: Always slice the rhubarb thinly and toss it in flour before adding it to the batter. This helps distribute the rhubarb evenly and prevents it from sinking.
-
Overmixing the batter: Mixing too much can lead to a dense cake. Stop mixing as soon as the dry ingredients are just incorporated for a light, fluffy texture.
-
Skipping the sugar sprinkle: Don’t forget to sprinkle sugar on top before baking. This creates a lovely crust that adds flavor and texture to your Rhubarb Cake.
-
Ignoring oven temperature: Always preheat your oven fully before baking. An oven that isn’t hot enough can cause the cake to bake unevenly.
-
Not checking for doneness: Use a toothpick to check if your cake is done. If it comes out with wet batter, give it more time; moist crumbs are fine but avoid underbaking.
Storage & Reheating Instructions
Refrigerator Storage
- Store in an airtight container for up to 3 days.
- Allow the cake to cool completely before sealing it for best results.
Freezing Rhubarb Cake
- Wrap tightly in plastic wrap or aluminum foil.
- Freeze for up to 3 months for optimal freshness.
Reheating Rhubarb Cake
- Oven: Preheat your oven to 350°F, place the cake on a baking sheet, and heat for about 10-15 minutes.
- Microwave: Heat individual slices on a microwave-safe plate for about 20-30 seconds until warm.
- Stovetop: Place slices in a skillet over low heat, covering them with a lid. Heat gently until warmed through.
