How to Make Moist Rhubarb Cake with Butter Sauce
Ingredients
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1 cup sugar
- 1/2 cup butter, softened
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 cup buttermilk
- 2 cups chopped rhubarb
- 1/2 cup brown sugar
- 1/4 cup butter
- 1/4 cup heavy cream
Helpful Notes:
- Buttermilk Substitute: If you don’t have buttermilk on hand, mix one tablespoon of vinegar or lemon juice with enough milk to make one cup. Let it sit for about 5 minutes before using.
- Room Temperature Ingredients: Ensure your eggs and butter are at room temperature for easier mixing and better incorporation of air.
Directions
- Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan thoroughly to prevent sticking.
- In a medium bowl, whisk together the flour, baking powder, baking soda, and salt until well combined. Set aside.
- In another large bowl, cream together the sugar and softened butter using an electric mixer on medium speed until light and fluffy. This should take about 2-3 minutes.
- Beat in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract to enhance the flavor.
- Gradually add the flour mixture and buttermilk to the butter mixture, starting and ending with the flour. Mix until just combined—overmixing can lead to a dense cake.
- Gently fold in the chopped rhubarb, ensuring it’s evenly distributed without breaking it up too much. Pour the batter into the prepared baking pan.
- Bake in the preheated oven for 35-40 minutes, or until a toothpick inserted into the center comes out clean. The cake should be golden around the edges and spring back when lightly pressed.
- For the butter sauce, combine the brown sugar, 1/4 cup butter, and heavy cream in a saucepan over medium heat. Stir continuously until the mixture is smooth, then let it simmer for 3-5 minutes. The sauce will thicken slightly while cooking.
- Serve the cake warm, generously drizzled with the buttery sauce for a decadent finish.
How to Serve Moist Rhubarb Cake with Butter Sauce

Pair this delightful cake with vanilla ice cream or whipped cream for an extra layer of indulgence. It makes a lovely dessert for casual gatherings or more formal events, giving you the freedom to impress your guests with ease.
