Ingredients

Topping

  • 1/2 cup all-purpose flour
  • 2/3 cup brown sugar
  • 1/4 cup unsalted butter
  • pinch salt

Cake

  • 1 1/2 cups all-purpose flour
  • 2 teaspoons baking powder
  • 1/2 teaspoons salt
  • 1/2 cup butter softened
  • 2/3 cup granulated sugar
  • 2 eggs at room temperature
  • 1/4 cup sour cream
  • 2 teaspoons pure vanilla extract
  • 3 cups rhubarb chopped into 1/4 inch pieces

Instructions

  • Preheat the oven to 350 degrees F. Grease and flour an 8 x 8 inch square baking pan

Streusel Topping

  • In a food processor (or using a bowl and fork), pulse 1/2 cup flour, 2/3 cup brown sugar, 1/4 cup butter, and salt, until crumbly (30 seconds or so).

Cake

  • In a medium mixing bowl, whisk together the flour, baking powder and salt. Set aside.
  • In the bowl of a stand mixer fitted with the paddle attachment, cream together the butter and sugar on medium speed (about 3 minutes).
  • Add the eggs, sour cream and vanilla, and beat to combine, scraping down the bowl as needed (about 2-3 minutes).
  • Add the flour mixture and mix on low speed until just combined. The batter will be thick.
  • Remove the bowl from the mixer and fold in the rhubarb until evenly distributed.
  • Spread the batter evenly into the prepared baking pan and bake in the preheated oven for 45-60 minutes, until a toothpick inserted in the center comes out clean. Serve at room temperature, or slightly warm.
