  • 1/2 c unsalted butter (softened)
  • 1 1/2 c granulated sugar
  • 1 large egg
  • 1 tsp vanilla
  • 2 c flour
  • 1 tsp baking soda
  • 1/4 tsp salt
  • 1/4 tsp cinnamon
  • 1 c buttermilk
  • 2.5 - 3 c chopped rhubarb (fresh or frozen)

Crumble Topping:

  • 1 c packed brown sugar
  • 2 tsp cinnamon
  • 1/4 c unsalted butter (softened)
  • 1/4 c flour


  1. Preheat oven to 350F.
  2. In large bowl, beat the butter and sugar until pale and creamy, about 3 minutes. Beat in the egg and vanilla.
  3. In a medium bowl, whisk the flour, baking soda, salt, and cinnamon. Add to the butter mixture in two additions, alternating with the buttermilk.
  4. Fold in the chopped rhubarb. (Tip: if using frozen rhubarb, you may want to lightly coat the rhubarb with some extra flour to absorb the moisture).
  5. Spread the batter in a parchment lined 9"x13" baking pan.
  6. In a small bowl, hand mix together the butter, brown sugar, cinnamon, and flour to make the sugar crumble topping. Scatter this mixture over the baking pan.
  7. Bake for 40-50 minutes, or until a toothpick comes out clean.
  8. Let cool. Serve on its own, or with a scoop of vanilla ice-cream!
