Rhubarb Crumb Cake is a delightful dessert that perfectly balances the tartness of rhubarb with the sweetness of a buttery cake and a crumbly, spiced topping. This rustic treat is moist, tender, and topped with a golden, crunchy streusel that adds the perfect texture. Ideal for spring and summer when rhubarb is in season, this cake is wonderful as an afternoon snack, a brunch centerpiece, or a light dessert served with a dollop of whipped cream.
Ingredients
For the Cake:
- 1/2 cup unsalted butter, softened
- 1 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/2 cup sour cream or plain yogurt
- 1 3/4 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 2 cups rhubarb, chopped into small pieces
For the Crumb Topping:
- 3/4 cup all-purpose flour
- 1/2 cup brown sugar, packed
- 1 teaspoon cinnamon
- 1/4 teaspoon nutmeg (optional)
- 1/4 cup unsalted butter, melted
Instructions
- Preheat the Oven: Preheat your oven to 350°F (175°C). Grease a 9×9-inch baking pan or line it with parchment paper.
- Prepare the Crumb Topping: In a small bowl, mix together the flour, brown sugar, cinnamon, and nutmeg. Add the melted butter and stir until the mixture forms crumbs. Set aside.
- Make the Cake Batter: In a large mixing bowl, cream the butter and granulated sugar together until light and fluffy, about 2–3 minutes. Beat in the eggs, one at a time, followed by the vanilla extract and sour cream.
- Combine Dry Ingredients: In a separate bowl, whisk together the flour, baking powder, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, mixing just until combined. Gently fold in the chopped rhubarb.
- Assemble the Cake: Pour the batter into the prepared baking pan and spread it evenly. Sprinkle the crumb topping over the batter, ensuring it covers the entire surface.
- Bake: Bake in the preheated oven for 40–45 minutes, or until a toothpick inserted into the center of the cake comes out clean.
- Cool and Serve: Let the cake cool in the pan for 10 minutes before transferring it to a wire rack to cool completely. Slice and serve on its own or with whipped cream or vanilla ice cream.
Rhubarb Crumb Cake is a cozy, homestyle dessert that highlights the tangy flavor of rhubarb against the warmth of a cinnamon-spiced crumb. It’s a delicious way to celebrate rhubarb season!
