Ultimate Guide to Rhubarb Muffins with Cinnamon Sugar Topping

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.
