Ingredients

Scale

For the Rhubarb Topping

4 cups fresh rhubarb, chopped into small pieces
1/2 cup unsalted butter
3/4 cup brown sugar
1 teaspoon vanilla extract

For the Cake Batter

1 1/2 cups all-purpose flour
1 teaspoon baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
1/2 cup unsalted butter, softened
3/4 cup granulated sugar
2 large eggs
1 teaspoon vanilla extract
1/2 cup sour cream or plain yogurt
1/2 cup milk

Instructions

Step 1

Preheat your oven to 175°C (350°F). Grease a 9-inch round cake pan or baking dish well to prevent sticking.

Step 2:

Prepare the rhubarb topping. Melt the butter directly in a saucepan or microwave-safe bowl, then stir in the brown sugar and vanilla extract until combined. Pour the mixture evenly into the prepared cake pan.

Step 3:

Spread the chopped rhubarb evenly over the brown sugar mixture. Make sure the rhubarb is distributed evenly so every slice gets plenty of fruit topping.

Step 4:

In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.

Step 5:

In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

Step 6:

Gradually add the dry ingredients to the wet ingredients, alternating with the sour cream and milk. Mix until just combined, being careful not to overmix the batter.

Step 7:

Carefully spread the cake batter over the rhubarb layer using a spatula. Smooth the top evenly.

Step 8:

Bake for 40–50 minutes or until a toothpick inserted into the center comes out clean and the top is golden brown.

Step 9:

Allow the cake to cool in the pan for about 10–15 minutes. Carefully run a knife around the edges, then invert the cake onto a serving plate while still slightly warm.

Step 10:

Let the cake cool slightly before slicing and serving. The caramelized rhubarb topping will become glossy and beautifully rich as it settles.

Notes

Rhubarb naturally releases moisture during baking, so avoid using overly large pieces. Smaller chopped rhubarb cooks more evenly and creates a better topping texture.

When inverting the cake, do so while the cake is still warm. Waiting too long may cause the caramelized topping to stick to the pan.

If using frozen rhubarb, thaw and drain it thoroughly before using to prevent excess moisture in the cake.
