These crispy rhubarb muffins feature a delightful cinnamon sugar streusel topping that balances tart rhubarb with sweet, crunchy texture. Perfect for breakfast or a snack, they are quick, easy, and comforting.
If rhubarb is out of season, frozen rhubarb works well after thawing and draining excess moisture. Avoid overmixing the batter to keep muffins tender. Keep butter cold when making streusel for a crispy topping. Let muffins cool completely on a wire rack to maintain topping crispness. Grease muffin tin or use liners to prevent sticking. For gluten-free, substitute flour 1:1 with gluten-free baking flour. For vegan, use flax egg, dairy-free yogurt, and vegan butter substitute.
