🍰 Rhubarb Cake with Warm Butter Sauce 🌿

A nostalgic dessert bringing together tart rhubarb and rich, velvety butter sauce for a match made in heaven.

🌸 Introduction

Rhubarb has long been a cherished springtime ingredient — known for its tartness, vibrant color, and nostalgic pull. This cake transforms the humble stalk into a stunning dessert, blending its tang with the sweetness of sugar and the warmth of a creamy butter sauce. Perfect for gatherings, tea time, or a cozy evening in, this Rhubarb Cake with Butter Sauce is more than just dessert — it’s comfort in every bite.

📜 History

Rhubarb first made its way into European kitchens in the 1600s, originally used for medicinal purposes. It wasn’t until sugar became more accessible that rhubarb’s culinary potential was fully realized. In Midwest America, rhubarb became a staple in pies, crisps, and cakes — often called “pie plant.” This recipe is a vintage-style dessert passed down through generations, often found handwritten in old recipe boxes. The butter sauce? A rich, old-fashioned topping used in Southern kitchens to enhance spice cakes and fruit desserts. Together, they make an unforgettable pairing.

🛠️ Formation of the Cake

The beauty of this cake lies in the balance — soft crumb, moisture from the rhubarb, and a delicate crisp edge when baked just right. The warm butter sauce is poured over the cake, soaking into every crevice like liquid gold. You can serve it warm or chilled, but it’s always best with love and a spoon.

🧾 Ingredients

For the Rhubarb Cake:

  • 4 cups all-purpose flour
  • 2 teaspoons baking soda
  • 1 teaspoon salt
  • 2 cups granulated sugar
  • 2 large eggs
  • 2 cups buttermilk (or 2 cups milk + 2 tbsp vinegar)
  • 4 cups chopped fresh rhubarb (about ½ inch pieces)
  • 1 teaspoon vanilla extract
  • Optional: ½ teaspoon cinnamon for warmth

For the Warm Butter Sauce:

  • 1 cup (2 sticks) unsalted butter
  • 1 cup granulated sugar
  • 1 cup heavy cream
  • 1 teaspoon vanilla extract
  • Pinch of salt

🍽️ Instructions

Step 1: Prepare the Batter

  1. Preheat your oven to 350°F (175°C).
  2. In a large bowl, whisk together flour, baking soda, salt (and cinnamon if using).
  3. In a separate bowl, beat sugar, eggs, and buttermilk until smooth. Add vanilla.
  4. Gradually stir in the dry ingredients until fully combined — do not overmix.
  5. Fold in the chopped rhubarb evenly. The batter will be thick and speckled with rhubarb.

Step 2: Bake

  1. Grease and flour a 9×13-inch pan.
  2. Pour the batter into the pan and smooth the top.
  3. Bake for 45–55 minutes, or until a toothpick inserted in the center comes out clean.
  4. Let cool slightly while you prepare the butter sauce.

Step 3: Make the Butter Sauce

  1. In a saucepan over medium heat, combine butter, sugar, and cream.
  2. Stir constantly until the sugar dissolves and mixture begins to simmer (do not boil hard).
  3. Remove from heat and stir in vanilla and a pinch of salt.

Step 4: Serve

  • Slice the warm cake and drizzle generously with butter sauce.
  • Add a scoop of vanilla ice cream or a dollop of whipped cream for extra indulgence.
