Ingredients

For the Rhubarb Filling:

  • 6 cups about 1.5 lbs or 680g fresh or frozen rhubarb, trimmed and sliced into ½-inch pieces (if using frozen, do not thaw)
  • ¾ cup to 1 cup granulated sugar (adjust to taste)
  • 2 tablespoons all-purpose flour OR cornstarch
  • 1 teaspoon lemon zest (optional)
  • ½ teaspoon vanilla extract
  • 1 pinch salt

For the Cobbler Topping:

  • 1 ½ cups all-purpose flour
  • ¼ cup granulated sugar
  • 2 teaspoons baking powder
  • ½ teaspoon salt
  • 6 tablespoons ¾ stick unsalted butter, cold and cut into small cubes
  • ½ cup milk (whole or 2% recommended (or buttermilk))
  • 1 large egg (optional, for a richer, more cake-like topping)
  • ½ teaspoon vanilla extract
  • 1-2 tablespoons granulated sugar (for sprinkling on top (optional))


Instructions

  1. Prepare Oven & Rhubarb: Preheat oven to 375°F (190°C). If using fresh rhubarb, wash, trim ends, and discard all leaves (they are toxic). Slice stalks into ½-inch pieces.
  2. Make Rhubarb Filling: In a large bowl, combine sliced rhubarb, ¾ cup to 1 cup granulated sugar, 2 tablespoons flour (or cornstarch), optional lemon zest, ½ teaspoon vanilla extract, and a pinch of salt. Toss gently to coat. Pour into the 9×13 inch baking dish, spreading evenly. Fresh, vibrant red rhubarb stalks being chopped on a wooden cutting board, a key ingredient for a rhubarb cobbler recipe.
  3. Prepare Cobbler Topping: In a medium bowl, whisk together 1 ½ cups all-purpose flour, ¼ cup granulated sugar, 2 teaspoons baking powder, and ½ teaspoon salt. Add 6 tablespoons cold, cubed butter. Cut in using a pastry blender or fingertips until mixture resembles coarse crumbs.
  4. Combine Wet & Dry Topping Ingredients: In a separate small bowl, whisk together ½ cup milk, 1 large egg (if using), and ½ teaspoon vanilla extract. Pour the wet ingredients into the dry ingredients. Stir with a fork or spatula until just combined. Do NOT overmix; a few lumps are okay.

  5. Assemble Cobbler: Drop spoonfuls of the topping batter evenly over the rhubarb filling. It’s okay if there are gaps. Optional: Sprinkle 1-2 tablespoons of granulated sugar over the topping.
  6. Bake: Place in the preheated oven and bake for 40-50 minutes, or until the filling is bubbly around the edges and the topping is golden brown and cooked through. (A toothpick inserted into the center of a biscuit should come out clean or with moist crumbs).
  7. Cool & Serve: Remove from oven and let cool on a wire rack for at least 15-20 minutes before serving. This allows the filling to thicken. Serve warm. A metal bowl filled with a buttery, crumbly topping mixture for a rhubarb cobbler recipe, with a spoon.

Notes

Rhubarb Leaves: Remember, only the stalks of rhubarb are edible. The leaves contain oxalic acid and are poisonous. Discard them safely.
Frozen Rhubarb: You can use frozen rhubarb without thawing. You might need to add 5-10 extra minutes to the baking time.
Topping Texture: For a more biscuit-like topping, omit the egg. For a more cake-like topping, include the egg.
Don’t Overmix Topping: This is crucial for a tender topping. Mix only until just combined.
Sweetness: Rhubarb’s tartness varies. Adjust sugar in the filling to your preference.
Storage: Cool completely, cover, and store at room temperature for up to 2 days or in the refrigerator for up to 4-5 days. Reheat in a 350°F (175°C) oven for best results.
