Tips to Make Sour Cream Rhubarb Coffee Cake
- Room Temperature Ingredients: Make sure your butter and eggs are at room temperature for the best mixing results.

- Cinnamon Swirl: For an extra flair, create a swirling pattern with the cinnamon topping before baking!
- Substitutions Are Welcome: Light brown sugar can replace white sugar if you want a deeper flavor.
Variation
Want to switch things up? Consider adding walnuts or pecans for a delightful crunch! You can also swap in yogurt for the sour cream if you’re looking for a twist or even try it with orange zest to brighten up the flavor.
FAQs
- Can I use frozen rhubarb? Yes, just thaw and drain any excess moisture before using!

- How can I make it vegan? Substitute the eggs with a flax egg, use plant-based butter, and enjoy vegan sour cream to maintain that same creamy texture!
