  • 1 cup granulated sugar
  • 1/2 cup butter
  • 2 large eggs

Rhubarb Layer:

  • 3 cups fresh chopped rhubarb (I would use 4 cups!)

Crumble Layer:

  • 1 cup all purpose flour
  • 1/4 cup brown sugar
  • 1/2 tsp ground cinnamon

  1. Preheat your oven to 350 degrees F.

Rhubarb Sour Cream Cake:

  1. Whisk together the flour, baking powder, baking soda and salt. Set aside.

  3. Add the eggs, one at a time.
  4. Add the vanilla. Mix well.
  5. To the butter mix, add 1/3 of the flour mix, then 1/2 of the sour cream. Repeat until all combined.

Rhubarb Layer:

  1. In a bowl, toss the chopped rhubarb with the sugar.
  2. Let rest for about 5 minutes.

Crumble Layer:

  1. Whisk together the flour, brown sugar, cinnamon and salt.
  2. Then stir in the melted butter, and mix until the mixture is the consistency of sand. (I used a hand processor to do this)

Putting the cake together:

  1. Line a 9 x 9 inch pan with parchment paper.
  2. Spread the cake batter evenly into the pan.
  3. Add the rhubarb to cover the batter.
  4. Sprinkle the cake with the crumble mixture.
