- 9×9 square baking pan
- Parchment paper (optional)
- Mixing bowls
- Whisk
Importance of Each Tool
- Stand mixer or electric beaters: These tools help achieve the fluffy texture needed for the batter by thoroughly creaming butter and sugar.
- 9×9 square baking pan: The right size ensures even baking and an ideal portion size for serving.
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
For the Rhubarb
- 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 with overhanging ends to easily lift out the cooled cake.
Step 2: Prepare the Buttermilk Mixture
Stir the lemon juice into the half and half (or cream/buttermilk) and set aside.
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. Beat in the egg and vanilla extract, scraping down the bowl as necessary.
Step 4: Toss Rhubarb with Flour
Take 1 tablespoon of flour from your total flour amount and toss it with the sliced rhubarb in a separate bowl. This helps prevent them from sinking in the batter.
Step 5: Combine Dry Ingredients
In another bowl, whisk together the remaining flour, baking powder, and salt.
Step 6: Mix Batter Together
Add half of the flour mixture to your butter-sugar mixture and blend well. Then add all of your buttermilk mixture and blend again. Finally, add in the rest of your flour until just combined; do not over mix. Gently fold in your prepared rhubarb.
Step 7: Bake
Spread the batter evenly into your prepared pan. Sprinkle a little sugar on top before placing it in the oven. Bake for about 40-45 minutes until golden brown; check doneness by inserting a toothpick into the center—moist crumbs are fine!
Step 8: Cool Before Cutting
Allow the cake to cool slightly before cutting into squares. Enjoy this delicious Rhubarb Cake warm or at room temperature!

How to Perfect Rhubarb Cake
To ensure your Rhubarb Cake turns out perfectly every time, follow these helpful tips.
- Choose fresh rhubarb: Fresh, vibrant rhubarb ensures the best flavor and texture in your cake.
- Measure flour accurately: Use the spoon-and-level method to prevent adding too much flour, which can make the cake dense.
- Don’t overmix: Gently fold in ingredients to keep the cake light and fluffy; overmixing can lead to toughness.
- Adjust baking time: Every oven is different; check your cake a few minutes early to avoid overbaking.
- Cool before slicing: Allow the cake to cool slightly in the pan before transferring it to avoid crumbling when cutting.
Best Side Dishes for Rhubarb Cake
Pairing side dishes with Rhubarb Cake can enhance its flavors and create a well-rounded meal. Here are some delicious options.
- Fresh Fruit Salad: A mix of seasonal fruits provides sweetness and freshness that complements the tartness of rhubarb.
- Greek Yogurt Parfait: Layer yogurt with granola and berries for added texture and flavor alongside your cake.
- Cheese Platter: A selection of cheeses, especially creamy varieties like brie, balances the acidity from the rhubarb beautifully.
- Crispy Bacon Strips: The salty crunch of bacon adds an unexpected but delightful contrast to your sweet cake.
- Herbed Scones: Savory scones pair nicely, providing a balance between sweet and savory at brunch or tea time.
- Vanilla Ice Cream: A scoop on top makes for an indulgent dessert experience, perfect for warm days.
- Nutty Granola Bars: These provide crunch and energy, making them great for breakfast when served alongside cake.
Common Mistakes to Avoid
Making a Rhubarb Cake can be delightful, but there are common mistakes that can impact your results. Here’s how to avoid them:
-
Using Unripe Rhubarb: Unripe rhubarb can be too tart and fibrous. Always choose fresh, vibrant stalks that are firm and free of blemishes for the best flavor.
-
Overmixing the Batter: Overmixing can lead to a dense cake. Mix only until ingredients are just combined to keep your Rhubarb Cake light and fluffy.
-
Not Measuring Ingredients Accurately: Improper measurements can throw off the balance of flavors and textures. Use a kitchen scale or measuring cups to ensure accuracy.
-
Skipping the Sugar Topping: The sugar topping adds a delightful crunch and sweetness. Don’t skip this step; sprinkle it generously on top before baking.
-
Not Preheating Your Oven: A properly preheated oven ensures even baking. Always preheat your oven to 350°F before placing your cake inside.
