Introduction to Rhubarb Muffins
Rhubarb muffins with cinnamon sugar topping offer a delightful balance between tart and sweet. They’re:
- Great for breakfast or brunch
- A refreshing springtime treat
- Easy to freeze and reheat
Rhubarb adds a unique tang, while cinnamon sugar adds warmth and crunch. Together, they form a combination that’s both nostalgic and gourmet.
Why Rhubarb Stands Out
- Tart and vibrant: Offers contrast to sweet batters
- Seasonal freshness: Peak in spring and early summer
- Visual appeal: Pink-red hues brighten up baked goods
Rhubarb is one of the few vegetables used like a fruit. It elevates any baked item, especially when paired with cinnamon sugar topping.
