• Sour Cream: Keeps the cake moist and adds a slight tang that complements the rhubarb.
• Fresh Rhubarb, Diced: The star ingredient, offering bright tartness and vibrant color.

Rhubarb Cake Variations and Substitutes
For variations on this rhubarb cake that suit dietary preferences or pantry swaps:
• Gluten‑Free Flour: Replace the all‑purpose flour with a gluten‑free blend for a gluten‑free rhubarb cake.
• Greek Yogurt: Swap sour cream with Greek yogurt for a tangy twist and slightly lighter crumb.
• Brown Sugar: Substitute part of the white sugar with brown sugar for deeper, caramel‑like notes.
• Mixed Fruit: Add diced strawberries or apples alongside rhubarb for a fruit‑rich version that mellows tartness.
Step‑by‑Step Instructions
- 1. Preheat your oven to 350°F (175°C) and grease and flour a 9×13‑inch baking dish.
- 2. In a large mixing bowl, combine the all‑purpose flour, white sugar, baking soda, and salt.
- 3. Stir in the beaten eggs and sour cream until the batter is smooth and well blended.
- 4. Gently fold the diced rhubarb into the batter so that it is evenly distributed throughout.
- 5. Pour the batter into the prepared baking dish, spreading it out evenly with a spatula.
- 6. In a separate bowl, mix the softened butter with sugar and flour until the mixture becomes crumbly. This will form your streusel topping.
