Rhubarb Butter Cake Recipe

4.7 from 6 reviews

This rustic rhubarb cake is soft, tangy, and bursting with fresh rhubarb pieces, all topped off with a dreamy warm butter sauce that soaks into the crumb. A comforting spring and summer dessert best served warm with a scoop of vanilla ice cream.

Ingredients

Scale

Dry Ingredients:

  • 4 cups plain flour
  • 2 cups white sugar
  • 4 teaspoons baking powder
  • ½ teaspoon salt

Additional Ingredients:

  • 4 cups rhubarb, diced (fresh or frozen and thawed)
  • 2 cups milk
  • 6 tablespoons melted butter

Butter Sauce:

  • ½ cup unsalted butter
  • 1 cup granulated sugar
  • ¾ cup heavy cream

Instructions

  1. Preheat and Prep: Preheat oven to 350°F (175°C). Grease a 9×13 inch baking pan. In a large bowl, whisk together flour, sugar, baking powder, and salt.
  2. Combine Wet and Dry: Stir in diced rhubarb, milk, and melted butter until just combined. Do not overmix. Pour batter into prepared pan and spread evenly.
  3. Bake: Bake for 45–60 minutes, or until a toothpick inserted in the center comes out clean. Remove from oven and let it cool slightly.
  4. Make the Butter Sauce: In a saucepan, combine butter, sugar, and heavy cream. Bring to a boil over medium heat, stirring often. Boil for 1 minute, then remove from heat and let cool slightly.
  5. Serve: Slice the cake and serve warm, drizzled generously with the butter sauce. Optional: top with vanilla ice cream, whipped cream, or fresh berries for a deluxe finish.
