Ingredients
Ingredients
- 2 cups chopped rhubarb, fresh and trimmed
- 1 cup granulated sugar
- 1/2 cup unsalted butter, softened to room temperature
- 2 large eggs, at room temperature
- 1 teaspoon vanilla extract
- 1 1/2 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon salt
- 1/4 cup milk, whole or 2% room temperature
- 1/2 cup butter, for sauce, unsalted and melted
- 1 cup powdered sugar, sifted for the sauce
Instructions
- Preheat your oven to 350°F (175°C). Grease a baking pan with butter or nonstick spray and line it with parchment if you prefer easy removal. A 9×9 inch pan works well.
- In a large bowl, cream together the softened butter and granulated sugar until light and fluffy. This takes about 2 to 3 minutes with an electric mixer on medium speed, or a little longer by hand.
- Beat in the eggs one at a time, mixing well after each addition, then stir in the vanilla extract. Scrape down the bowl so everything is evenly combined.
- Combine the flour, baking powder, and salt in a separate bowl. Gradually add this dry mixture to the creamed mixture alternately with the milk, beginning and ending with the flour. Mix until just combined — do not overmix.
- Gently fold in the chopped rhubarb with a spatula so the pieces are evenly distributed. Pour the batter into the prepared baking pan and smooth the top with an offset spatula.
- Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean or with a few moist crumbs but no raw batter. Let the cake cool in the pan for 10 minutes, then transfer to a wire rack.
- For the sauce, melt the 1/2 cup butter in a small saucepan over low heat. Remove from heat and whisk in the powdered sugar until smooth and glossy. If it’s too thick, add a splash of milk to reach desired consistency.
- Serve warm slices of cake with a generous drizzle of the butter sauce over each piece. Enjoy!
Notes
Use fresh rhubarb when possible. Room temperature ingredients improve texture. Don’t overmix the batter.
