Let’s gather our ingredients. Here’s what you’ll need to make this amazing rhubarb cake:
- ½ teaspoon salt
- 1 ¼ cups white sugar
- 2 large eggs (beaten)
- 2 cups all-purpose flour
- 1 cup sour cream

Let’s Bake: Step-by-Step Instructions
Alright, let’s get baking! Follow these simple steps for rhubarb cake perfection:
- Preheat & Prep: Preheat your oven to 350°F (175°C) and grease and flour a 9×13-inch baking dish. This prevents the cake from sticking.
- Dry Ingredients Unite: In a large bowl, combine 2 cups of flour, 1 ¼ cups of sugar, baking soda, and salt. This ensures even distribution of leavening agents.
- Wet Meets Dry: Stir in the beaten eggs and sour cream until smooth. The sour cream adds moisture and tang.
- Rhubarb Integration: Gently fold in the diced rhubarb until evenly distributed. Be careful not to overmix.
- Batter Placement: Pour the batter into the prepared dish and spread evenly.
- Streusel Creation: In a medium bowl, mix together 1 cup sugar and softened butter until smooth.
- Streusel Crumble: Stir in the remaining ¼ cup flour to make a crumbly streusel.
- Streusel Sprinkle: Sprinkle the streusel over the batter and dust lightly with cinnamon.
- Bake Time: Bake for about 45 minutes, or until a toothpick inserted in the center comes out clean. Keep an eye on your oven; baking times may vary.
- Cool & Serve: Let cool slightly, slice, and serve warm or at room temperature. Enjoy!
