Description
A lemony sour cream cake batter that perfectly complements tart rhubarb with a soft, custardy interior and a crispy, crunchy sugary crust!
Ingredients
Scale
- 4 tablespoons (57 grams) butter, melted and cooled, plus more for softened butter for greasing the pan
- 1 cup (120 grams) all-purpose flour, plus more for dusting the pan
- 3/4 teaspoons (3 grams) baking powder
- Pinch of kosher salt
- 2 large eggs, plus 1 large egg yolk
- 1–1/2 cups (297 grams) granulated sugar, plus more for sprinkling the top
- 1/4 cup sour cream
- 2 tablespoons dark rum (such as Meyer’s)
- Zest of 1 large lemon
- 12 ounces rhubarb stalks, trimmed and cut lengthwise into 1/4-inch-thick strips
Instructions
- Preheat the oven to 350°. Butter and flour a 9-inch cake pan, tapping the bottom and sides of the pan to remove excess flour. Set aside.
- Combine the baking powder, salt and flour in a small mixing bowl and stir to mix.
- Whisk the eggs, egg yolk and sugar together in a large mixing bowl until lightened in color and thick, about 1 minute. Whisk in the melted butter, sour cream, rum and lemon zest just until combined. Add the dry ingredients to the wet ingredients and gently fold together until smooth. Pour the batter into the prepared pan, spreading to the edges and level the top with a spatula. Transfer to the refrigerator to chill for 10 minutes.
- Generously sprinkle the top with granulated sugar. Arrange the rhubarb over the cake batter in whatever design you like, cutting the rhubarb to fit as needed. Don’t press the fruit in to the batter; just gently place on top and let rest on the surface. Sprinkle with a little more sugar. Transfer to the oven and bake until golden brown and a cake tester comes out mostly clean, about 45 to 55 minutes. Remove from the oven and let cool for 10 minutes. Run a thin paring knife around the sides of the cake. Gently invert onto a plate or cooling rack, immediately inverting again to turn the cake right side up. Allow to cool completely before serving.
Notes
Removing the cake around the 45-minute mark will result in a more custardy texture to the cake; removing the cake around the 55-minute mark will result in a more firm, set cake.
