Description
Classic rhubarb coffee cake recipe with a sour cream batter, fresh rhubarb layer, and thick brown sugar cinnamon streusel topping. Bakes in 55 minutes. Serves 9 squares.
Ingredients
- 2 cups all-purpose flour, plus 1 tablespoon for tossing rhubarb
- 3/4 cup granulated sugar
- 3/4 cup light brown sugar, packed
- 2 teaspoons baking powder
- 1 teaspoon fine sea salt
- 1 1/2 teaspoons ground cinnamon
- 12 tablespoons unsalted butter, cold and cut into small cubes
- 2 large eggs, room temperature
- 1 cup full-fat sour cream
- 1 teaspoon pure vanilla extract
- 1 1/2 cups fresh rhubarb, chopped into 1/2-inch pieces
Instructions
- Preheat oven to 350°F. Grease and line a 9×9 inch baking pan with parchment. In a large bowl, whisk flour, both sugars, baking powder, salt, and cinnamon. Rub in cold butter cubes with fingertips until the mixture resembles wet coarse sand with pea-sized butter pieces.
- Scoop out 1 1/4 cups of the dry base into a separate bowl and set aside as the streusel topping. To the remaining mixture, add eggs, sour cream, and vanilla. Whisk until a thick smooth batter forms.
- Toss chopped rhubarb with the reserved 1 tablespoon of flour until lightly coated. Pour batter into prepared pan and spread evenly to all corners. Scatter flour-coated rhubarb over the entire batter surface in a single even layer.
- Sprinkle the reserved streusel generously and evenly over the rhubarb layer, covering it completely. Press lightly with fingertips to make gentle contact with the layer below.
- Bake at 350°F for 45 to 55 minutes until a toothpick inserted in the center comes out clean and the streusel is deep golden brown. Cool in pan on a wire rack for at least 15 minutes before slicing.
Notes
Store loosely covered at room temperature for up to 3 days or refrigerated in an airtight container for up to 5 days.
To make ahead, assemble the full unbaked cake including streusel, cover with plastic wrap, and refrigerate overnight. Bake from cold adding 5 extra minutes to the bake time.
Frozen rhubarb works perfectly. Do not thaw. Toss frozen pieces in flour and layer directly onto the batter.
For strawberry rhubarb coffee cake, replace 1/2 cup rhubarb with diced fresh strawberries. For almond rhubarb coffee cake, add 1/2 teaspoon almond extract to the batter and 2 tablespoons sliced almonds to the streusel.
