Ingredients You’ll Need
Here’s everything you’ll need to make this incredible Rhubarb Cake with Butter Sauce. Gather the ingredients, and you’ll be on your way to creating a dessert that’s sure to become a family favorite.
For the Cake:
- 4 cups all-purpose flour: The foundation of your cake, creating the soft, fluffy texture.
- 2 cups granulated sugar: This adds sweetness and helps balance the tartness of the rhubarb.
- 4 teaspoons baking powder: To give the cake a light, airy rise.
- 1/2 teaspoon salt: To enhance the overall flavor.
- 4 cups diced rhubarb: Fresh or frozen and thawed, this is the star ingredient, offering that signature tangy bite.
- 2 cups milk: To help create the smooth batter and maintain moisture in the cake.
- 6 tablespoons melted butter: For richness and moisture.
For the Butter Sauce:
- 1/2 cup (1 stick) butter: The base of your luscious sauce, providing richness and flavor.
- 1 cup sugar: To sweeten the sauce and complement the tartness of the cake.
- 3/4 cup heavy cream: The creamy element that gives the sauce its velvety smooth texture.
Step-by-Step Instructions to Make Rhubarb Cake with Butter Sauce
1. Prepare the Oven and Pan
Begin by preheating your oven to 350°F (175°C). Grease a 9×13-inch baking pan with butter or non-stick spray to ensure your cake doesn’t stick. You could also line the pan with parchment paper for easy removal.
2. Mix the Dry Ingredients
In a large bowl, whisk together 4 cups of all-purpose flour, 2 cups of sugar, 4 teaspoons of baking powder, and 1/2 teaspoon of salt. This will create the dry base of your cake batter, so make sure the dry ingredients are evenly combined.
3. Add the Wet Ingredients
Now, add the diced rhubarb, 2 cups of milk, and 6 tablespoons of melted butter to the dry ingredients. Stir the mixture just until combined. The batter should be thick, and the rhubarb should be well distributed throughout.
4. Bake the Cake
Pour the cake batter into your prepared baking pan. Smooth the top with a spatula if necessary. Place the pan in the preheated oven and bake for about 45 minutes or until a toothpick inserted into the center comes out clean. You’ll know the cake is done when it has a golden brown top and the edges begin to pull away from the sides of the pan.
5. Make the Butter Sauce
While the cake is baking, you can prepare the luscious butter sauce. In a medium saucepan, combine 1/2 cup of butter, 1 cup of sugar, and 3/4 cup of heavy cream. Place the pan over medium heat and bring the mixture to a boil. Stir frequently to prevent burning. Once it reaches a boil, continue stirring and cook for about 1 minute. The sauce will thicken slightly.
6. Serve the Cake
After the cake has cooled slightly, slice it into squares. Pour the warm butter sauce generously over the top of each piece of cake, allowing it to seep into the layers for extra flavor.
Why Rhubarb Cake with Butter Sauce is Perfect for Every Occasion
1. A Taste of Spring
Rhubarb is a quintessential spring vegetable, often one of the first to appear in gardens. If you’ve grown tired of winter’s heavier desserts, this cake brings a refreshing change. The tartness of the rhubarb, paired with the sweetness of the butter sauce, offers a perfect balance for the warmer months. Whether you serve it at a spring picnic or for a casual family dessert, it’s sure to impress.
2. Great for Potlucks or Parties
This cake is easy to make in large batches and is a great choice for potlucks or family gatherings. With its unique flavor profile and comforting texture, it stands out among typical desserts like cookies or brownies. Plus, the butter sauce adds a decadent touch that makes it feel special.
3. Flexible Recipe
Don’t have fresh rhubarb on hand? No problem! You can easily substitute frozen rhubarb (just make sure to thaw it thoroughly). This recipe is also adaptable—you can tweak the amount of sugar in the cake or the sauce depending on your sweetness preference. Add a dash of cinnamon or vanilla for extra flavor, or even top the cake with whipped cream or a scoop of vanilla ice cream.
Tips for Success
- Don’t Overmix the Batter: While it’s tempting to mix the ingredients vigorously, be sure to stir the batter gently. Overmixing can lead to a denser cake texture, while a light hand will help keep it airy and soft.
- Keep an Eye on the Cake: Every oven is different, so check your cake a few minutes before the suggested 45-minute bake time to avoid overbaking. The cake is ready when a toothpick inserted into the center comes out clean.
- Serve Warm: The butter sauce is best served warm and poured over the cake just before serving. This ensures that every bite is decadently rich and indulgent.
