Ingredients

Cake Base:

  • 2 cups 250g all-purpose flour
  • 1 tsp baking powder
  • 1/2 tsp baking soda
  • 1/2 tsp salt
  • 1/2 cup 115g unsalted butter, softened
  • 1 cup 200g granulated sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1 cup 240ml sour cream or Greek yogurt
  • 2 cups 240g chopped fresh rhubarb​

Optional Streusel Topping:

  • 1/2 cup 100g brown sugar
  • 1/3 cup 40g all-purpose flour
  • 1/4 cup 60g cold butter
  • 1/2 tsp ground cinnamon


Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×13-inch (23×33 cm) baking pan or line with parchment paper.
  2. In a medium bowl, whisk together flour, baking powder, baking soda, and salt.
  3. In a large bowl, cream butter and sugar until light and fluffy (about 3 minutes).

Notes

Fresh vs. Frozen Rhubarb: If using frozen rhubarb, thaw and drain excess liquid before adding to the batter.

Substitutions: Greek yogurt can be used in place of sour cream.

Serving Suggestions: Pairs well with vanilla ice cream or a dollop of whipped cream.
