- Prepare the Rhubarb: Dice your rhubarb into small pieces and set aside.
- Make the Batter: In a large mixing bowl, cream together 1/2 cup softened butter and 1 cup granulated sugar until light and fluffy. Add 2 large eggs, 1 cup sour cream, and 1 teaspoon vanilla extract to the bowl, mixing until combined.
- Combine Dry Ingredients: In another bowl, mix 2 cups flour, 1 teaspoon baking powder, 1 teaspoon baking soda, and 1/2 teaspoon salt. Gradually add the dry mixture to the wet ingredients, stirring until just combined. Gently fold in the diced rhubarb.

Top Tips for Perfecting Moist Sour Cream Rhubarb Coffee Cake with Streusel Topping
- Substitutions: For a Halal-friendly option, you can substitute unsalted butter with coconut oil or a vegan butter alternative. Ensure that your sour cream is also made with Halal-certified ingredients.
- Timing: For the best results, allow the cake to cool completely before slicing. This will help maintain its moisture.
- Avoiding Mistakes: Don’t skip the step of folding in the rhubarb gently; this prevents the batter from becoming too tough and helps maintain the cake’s light texture.
Storing and Reheating Tips
Store any leftovers in an airtight container in the refrigerator, where they will last for about 3-4 days. You can also freeze the cake for up to three months – simply wrap it tightly in plastic wrap and then in aluminum foil.
When you’re ready to enjoy it again, simply thaw it in the refrigerator overnight or at room temperature for a few hours. Reheat individual slices in the microwave for about 20-30 seconds, ensuring the cake remains moist and enjoyable.
Now that you have the complete guide to making the perfect Moist Sour Cream Rhubarb Coffee Cake with Streusel Topping, gather your ingredients, get baking, and create delicious memories with loved ones around the table! Happy baking!
