For the Cake:
-
2 cups all-purpose flour: This forms the base of the cake and provides structure.
-
1 1/2 cups granulated sugar: Sugar adds sweetness to the cake, balancing out the tartness of the rhubarb.
-
1 tsp baking soda: This is the leavening agent that helps the cake rise and become light and fluffy.
-
1/2 tsp salt: Salt enhances the flavors and balances the sweetness of the cake.
-
2 large eggs: Eggs help bind the ingredients together and provide moisture to the cake.
-
1 tsp vanilla extract: Vanilla adds a sweet, aromatic flavor that enhances the overall taste of the cake.
-
1 cup buttermilk: Buttermilk adds moisture to the cake and gives it a slight tanginess that complements the rhubarb.
-
1/2 cup unsalted butter, melted: Butter adds richness and helps create a tender, moist cake. It’s melted to mix easily with the other ingredients.
-
2 cups fresh rhubarb, chopped: The star of the dish, rhubarb, adds a refreshing, tart flavor that perfectly balances the sweetness of the cake.
For the Butter Sauce:
-
1/2 cup unsalted butter: Butter forms the base of the sauce and gives it its rich, creamy texture.

Tools Needed for Rhubarb Cake with Butter Sauce
While this recipe doesn’t require any specialized tools, having a few basic kitchen items will make the process smoother. Here’s a list of the tools you’ll need to create this delicious cake and sauce:
-
9×13-inch baking dish: This is the perfect size for this recipe, allowing the cake to bake evenly and providing enough space for the sauce to be absorbed. Be sure to grease and flour the baking dish before adding the cake batter.
-
Mixing bowls: You’ll need two mixing bowls—one for the dry ingredients and one for the wet ingredients. A third bowl will be needed to toss the chopped rhubarb with a little sugar before adding it to the cake batter.
-
Whisk: A whisk is essential for mixing the dry ingredients and for combining the wet ingredients smoothly.
-
Spatula or spoon: A spatula will help you mix the cake batter evenly and spread it out in the baking dish. It’s also useful for spreading the butter sauce over the cake once it’s done baking.
-
Saucepan: You’ll need a medium saucepan to melt the butter and prepare the butter sauce. This allows the ingredients to blend smoothly and thicken slightly as they cook.
-
Measuring cups and spoons: Accurate measurements are crucial for getting the right balance of ingredients in both the cake and the butter sauce.
-
Cooling rack: Once the cake is done baking, use a cooling rack to allow it to cool slightly before serving. This helps the butter sauce set while ensuring the cake doesn’t get soggy.
Part 3: Step-by-Step Guide to Making Rhubarb Cake with Butter Sauce
Step 1: Preheat the Oven and Prepare the Baking Dish
Start by preheating your oven to 350°F (175°C). Grease and flour a 9×13-inch baking dish to prevent the cake from sticking. You can also use cooking spray for convenience. This dish will hold the cake as it bakes, and the greasing ensures easy removal after baking.
Step 2: Prepare the Cake Batter
In a large mixing bowl, whisk together the 2 cups of all-purpose flour, 1 1/2 cups granulated sugar, 1 tsp baking soda, and 1/2 tsp salt. These dry ingredients will form the base of the cake.
In a separate medium mixing bowl, beat together the 2 large eggs, 1 tsp vanilla extract, 1 cup buttermilk, and 1/2 cup melted unsalted butter until smooth and combined.
Gradually add the wet ingredients into the dry ingredients, mixing until just combined. Be careful not to overmix, as this could result in a dense cake. Once the batter is smooth, gently fold in the chopped rhubarb. The rhubarb will add a tangy, fruity element that balances out the sweetness of the cake.
Step 3: Bake the Cake
Pour the cake batter into the prepared baking dish and spread it evenly. Bake the cake in the preheated oven for about 40-45 minutes, or until a toothpick inserted into the center comes out clean. The top should be golden, and the cake should feel firm to the touch.
Once baked, remove the cake from the oven and let it cool slightly in the baking dish.
Step 4: Prepare the Butter Sauce
While the cake is baking, prepare the butter sauce. In a medium saucepan, melt 1/2 cup unsalted butter over medium heat. Once the butter is melted, stir in 1 cup granulated sugar, 1/2 cup heavy cream, and 1 tsp vanilla extract.
Bring the mixture to a simmer and cook for about 2-3 minutes, stirring constantly, until the sauce thickens slightly and becomes smooth. The butter sauce should be rich and creamy, ready to be poured over the warm cake.
Step 5: Pour the Butter Sauce Over the Cake
Once the cake is done baking and has cooled slightly, pour the hot butter sauce evenly over the cake. The sauce will soak into the cake, making it extra moist and decadent. Let the cake sit for a few minutes to absorb the sauce before serving.
Step 6: Serve and Enjoy
Allow the cake to cool for a few more minutes before serving. Slice and enjoy this deliciously tangy and sweet Rhubarb Cake with Butter Sauce. It pairs wonderfully with a dollop of whipped cream or a scoop of vanilla ice cream for extra indulgence!
Frequently Asked Questions (FAQs)
Can I use frozen rhubarb instead of fresh rhubarb?
Yes, you can use frozen rhubarb in this recipe if fresh rhubarb is unavailable. Be sure to thaw and drain the frozen rhubarb to remove excess moisture, as this can affect the cake’s texture. Frozen rhubarb will work just as well, but fresh rhubarb provides a slightly firmer texture and brighter flavor.
Can I make this cake ahead of time?
Yes, you can prepare this cake ahead of time. You can bake the cake in advance, allow it to cool completely, and store it in an airtight container for up to 3 days. When ready to serve, reheat the cake in the oven and then pour the warm butter sauce over it just before serving.
Can I make this cake without the butter sauce?
While the butter sauce is a key part of the indulgence in this cake, you can skip it if you prefer a lighter version. Without the butter sauce, the cake will still be delicious, but the sauce adds a rich, decadent layer of sweetness that truly enhances the overall flavor.
Can I substitute the buttermilk?
Yes, if you don’t have buttermilk, you can make a quick substitute by adding 1 tablespoon of lemon juice or vinegar to 1 cup of regular milk. Let it sit for 5 minutes before using. This will give you the same tangy flavor that buttermilk adds to the cake.
How should I store leftovers?
Store any leftover Rhubarb Cake with Butter Sauce in an airtight container in the refrigerator for up to 3 days. The cake is best served warm, so consider reheating individual slices in the microwave or in a low-temperature oven for the best texture and flavor.
