This streusel-topped rhubarb coffee cake is a standout celebration of spring. With a tender, springy crumb, the cake is the perfect match for the rosy, tart rhubarb on top. The addition of buttermilk lends tanginess and richness to the cake batter, while the rhubarb is marinated in sugar before baking, softening the fibrous stalks to result in a deliciously jammy texture.

10 to 12 servings




Make the streusel:
  • Stir together flour, brown sugar, cinnamon, and salt in a medium bowl. Add butter; using fingers, work butter into flour mixture until completely incorporated and mixture clumps together. Cover and refrigerate until ready to use or up to overnight (12 hours).

Make the cake:
  • Preheat oven to 350°F. Lightly grease a 13- x 9-inch baking pan or dish with butter. Dust pan with flour, and shake out excess. Place rhubarb on a rimmed baking sheet, and sprinkle with 1/4 cup granulated sugar; toss to coat. Let stand, tossing occasionally, until sugar is mostly dissolved, 20 to 30 minutes.

  • Whisk together flour, salt, baking powder, and baking soda in a medium bowl; set aside. Beat butter and remaining 1 1/2 cups granulated sugar with a stand mixer fitted with the paddle attachment on medium speed until light and fluffy, about 2 minutes, stopping to scrape down sides of bowl as needed. With mixer running on medium speed, add eggs, 1 at a time, beating well after each addition. Reduce mixer speed to low, and beat in buttermilk and vanilla. With mixer running on low speed, gradually add flour mixture, beating until just incorporated, about 1 minute, stopping to scrape down sides of bowl as needed.

  • Transfer batter to prepared pan, and spread evenly. Arrange rhubarb lengthwise in a single layer on top of batter. Sprinkle with streusel. Bake in preheated oven until a wooden pick inserted in center of cake comes out clean, 55 minutes to 1 hour and 5 minutes. Remove from oven; let cake cool in pan on a wire rack at least 20 minutes or up to 6 hours. Serve warm, or let cool completely.
