What is Rhubarb Cake?
Rhubarb cake is a dessert made with fresh rhubarb, a plant known for its tart flavor. The tanginess of the rhubarb is balanced by the sweetness of the cake batter, creating a unique, refreshing dessert. Rhubarb’s slight acidity pairs well with sugar and spices, making it a popular choice for springtime baking.
Ingredients Needed for Rhubarb Cake
To make a moist rhubarb cake, you’ll need the following ingredients:
- Fresh rhubarb: 2 cups, chopped
- All-purpose flour: 2 cups
- Sugar: 1 1/2 cups
- Baking powder: 1 teaspoon
- Baking soda: 1/2 teaspoon
- Salt: 1/2 teaspoon
- Butter: 1/2 cup (1 stick), softened
- Eggs: 2 large
- Vanilla extract: 1 teaspoon
- Buttermilk: 1 cup
- Cinnamon: 1/2 teaspoon (optional, for added warmth)
- Optional toppings: Powdered sugar, whipped cream, or a streusel topping
Step-by-Step Instructions to Make Rhubarb Cake
- Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan or a round cake pan.
- Prepare the Rhubarb: Wash and chop the rhubarb into small pieces, about 1/2-inch thick. Set aside.
- Mix the Dry Ingredients: In a medium bowl, whisk together the flour, baking powder, baking soda, salt, and cinnamon (if using).
- Cream the Butter and Sugar: In a large bowl, use an electric mixer to cream the softened butter and sugar until light and fluffy. Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract.
- Add the Buttermilk: Gradually add the buttermilk, alternating with the dry ingredients. Mix just until combined, being careful not to overmix.
- Fold in the Rhubarb: Gently fold the chopped rhubarb into the batter until evenly distributed.
- Bake the Cake: Pour the batter into the prepared pan and spread it out evenly. Bake for 40-45 minutes, or until a toothpick inserted into the center comes out clean. The cake should be golden and springy to the touch.
- Cool and Serve: Let the cake cool in the pan for 10 minutes before transferring it to a wire rack to cool completely. Dust with powdered sugar or top with whipped cream before serving.
Tips for Baking the Perfect Rhubarb Cake
- Use Fresh Rhubarb: Fresh rhubarb gives the best texture and flavor. If using frozen rhubarb, thaw and drain it well to avoid excess moisture.
- Don’t Overmix: Overmixing the batter can lead to a dense cake. Mix just until the ingredients are combined.
- Balance the Sweetness: Rhubarb is quite tart, so make sure to balance it with enough sugar. You can adjust the sugar to your taste if you prefer a more tart or sweet cake.
How to Store and Serve Rhubarb Cake
Rhubarb cake can be stored in an airtight container at room temperature for up to 3 days. If you want to keep it fresh longer, store it in the refrigerator for up to 5 days. To serve, dust the top with powdered sugar, or enjoy it warm with a scoop of vanilla ice cream or whipped cream.
Delicious Variations of Rhubarb Cake
- Strawberry Rhubarb Cake: Add 1 cup of fresh or frozen strawberries to the rhubarb for a sweet twist.
- Rhubarb Upside-Down Cake: Arrange sliced rhubarb on the bottom of the pan with a brown sugar glaze before pouring in the batter for a delicious upside-down version.
- Rhubarb Almond Cake: Add 1/2 cup of ground almonds to the batter for a nutty flavor that complements the rhubarb.
Health Benefits of Rhubarb

Common Mistakes to Avoid When Baking with Rhubarb
