Ingredients
  

For filling
  • 5 cup fresh rhubarb cut into 1-inch pieces
  • 1.25 cup sugar
  • 3 tbsp cornstarch
  • 0.5 cup water
For biscuit topping
  • 1.5 cup all-purpose flour
  • 0.25 cup sugar
  • 2 tsp baking powder
  • 0.5 tsp salt
  • 6 tbsp butter cold and cubed
  • 0.75 cup milk
  • sugar for sprinkling

Equipment

  • 1 sheet pan
  • 1 Dutch oven

Method
 

Preheat and prep the baking dish
  1. Preheat the oven to 375°F and butter a 2-quart baking dish with a thin coating to prevent sticking. Aim for an even sheen so the cobbler releases cleanly.
Make the rhubarb filling
  1. Combine rhubarb, sugar, cornstarch, and water in the buttered baking dish and mix well until the cornstarch disperses. You should see a lightly thickened, glossy coating on the fruit.
Make the biscuit topping
  1. Whisk together flour, sugar, baking powder, and salt in a bowl until evenly combined. The mixture should look uniform in color with no visible salt or baking powder clumps.
  2. Cut in the cold cubed butter until the mixture looks crumbly, with small pea-size pieces throughout. Keep the butter cold so it creates tender, flaky layers.
  3. Stir in the milk until just combined; the dough will be wet. Stop as soon as no dry flour remains to avoid tough topping.
Assemble and bake
  1. Drop spoonfuls of the wet dough over the rhubarb filling, spacing them so steam can reach the fruit. Leave some gaps so the filling bubbles up around the biscuit topping.
  2. Sprinkle the top with sugar for a lightly crunchy, rustic finish. Look for a light, even dusting across the dough mounds.
  3. Bake for 40-45 minutes at 375°F until the topping is golden and the filling is bubbling. You should see thick pink juices bubbling at the edges and under the dough.
Cool and serve
  1. Cool for 15 minutes before serving warm so the filling sets slightly. The cobbler should thicken to a spoonable texture without being runny.
  2. Serve warm with vanilla ice cream. The ice cream should melt into the bubbling rhubarb for a glossy finish.

Notes

Pro tip: keep the butter cold while making the biscuit topping for a more tender, biscuit-like texture. Store covered in the refrigerator up to 3 days; reheat in the oven or microwave until warm. Freezing is not recommended because the rhubarb texture can soften too much after thawing. For a dairy-reduced option, use plant-based cold butter and milk alternatives in the topping.
