Ingredients
Scale
Rhubarb Layer
- 3 cups fresh rhubarb, chopped into 1-inch pieces
- 1/4 cup granulated sugar
- 1/4 cup unsalted butter, melted
- 1/2 cup brown sugar, packed
Cake Batter
- 3/4 cup granulated sugar, divided (1/4 cup for rhubarb, 1/2 cup for batter)
- 1 cup all-purpose flour
- 1 teaspoon baking powder
- 1/4 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup milk
- 1 large egg
- 1 teaspoon vanilla extract
Instructions
- Preheat and Prepare Pan: Preheat the oven to 350°F (175°C) and lightly grease a 9-inch round baking pan to prevent sticking and ensure easy release of the cake.
- Prepare Rhubarb Layer: In a bowl, toss the chopped rhubarb with 1/4 cup of the granulated sugar to macerate and draw out moisture and sweetness. Spread this mixture evenly in the bottom of the prepared pan.
- Add Sugars and Butter: Drizzle the melted butter evenly over the rhubarb layer, then sprinkle the packed brown sugar uniformly on top to create a caramelized topping when baked.
- Mix Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking powder, baking soda, salt, and the remaining 1/2 cup granulated sugar until well combined.
- Combine Wet Ingredients: Add the milk, egg, and vanilla extract to the dry ingredients and mix gently until just combined and smooth, being careful not to overmix to keep the cake tender.
- Assemble Cake: Pour the batter evenly over the rhubarb layer in the pan, gently spreading it out to cover the fruit completely.
- Bake: Place the pan in the preheated oven and bake for 40 to 45 minutes, or until a toothpick inserted into the center of the cake comes out clean, indicating the cake is fully cooked.
- Cool and Invert: Allow the cake to cool in the pan for about 10 minutes to set. Carefully invert the cake onto a serving plate so the rhubarb layer is on top, revealing the beautiful caramelized fruit topping.
- Serve: Serve the cake warm or at room temperature. For an extra special treat, top with whipped cream or vanilla ice cream if desired.
Notes
- If using frozen rhubarb, thaw completely and drain well to avoid excess moisture in the cake.
- For added flavor, sprinkle cinnamon or orange zest into the rhubarb layer before baking.
- Serve with whipped cream or vanilla ice cream to enhance this simple dessert.
