Method
- Preheat oven to 400°F (200°C) and line a 12-cup muffin tin with liners or grease well.
- Whisk together flours, sugar, baking powder, cinnamon, baking soda, and salt in a bowl.
- In another bowl, whisk Greek yogurt, melted butter, eggs, and vanilla until smooth.
- Add dry ingredients to wet and fold gently until just combined. Do not overmix.
- Fold in diced rhubarb evenly throughout the thick batter.
- Divide batter evenly among muffin cups, filling slightly above the rim.
- Mix topping sugar and cinnamon, sprinkle over muffins, and lightly press to adhere.
- Bake for 20–22 minutes until golden and a toothpick inserted comes out clean.
- Cool in pan briefly, then transfer to a rack and serve warm or at room temperature.
Notes
Do not overmix the batter to keep muffins tender. Use 2% Greek yogurt for best texture. Add frozen rhubarb directly without thawing. Batter will be thick—this is normal. Muffins are best fresh but freeze well up to 3 months.
