Method
Prep and preheat
- Preheat oven to 350°F and grease a 9-inch springform pan until evenly coated.
Make the batter
- Cream butter and sugar until fluffy, then beat in eggs one at a time and mix in vanilla for a smooth, lighter batter.
- Whisk together all-purpose flour, baking powder, and salt in a separate bowl until evenly combined.
- Add dry ingredients to the butter mixture alternating with milk, mixing just until combined to keep the batter tender.
Top with rhubarb and bake
- Pour batter into the prepared springform pan and spread into an even layer.
- Arrange rhubarb pieces on top in a circular pattern so the cake surface shows rustic, artful rings.
- Sprinkle the rhubarb with 2 tablespoons sugar so the top caramelizes lightly during baking.
- Bake for 40-45 minutes at 350°F until the top is golden and a toothpick in the center comes out clean.
Cool, dust, and serve
- Cool the cake for 30 minutes to set the crumb and make slicing cleaner.
- Dust with powdered sugar right before serving for a finished, countryside-style look.
Notes
For neat slices, let the cake cool the full 30 minutes before removing the ring. Store covered in the refrigerator up to 3 days; for best texture, bring to room temperature before serving. Freezing is okay for up to 2 months—wrap tightly after fully cooled. For a lighter option, use unsalted butter and replace 1/4 cup of the sugar with a baking-friendly sugar substitute if desired.
