Method
Prep
- Preheat the oven to 400°F and line a 12-cup muffin tin with paper liners.
- Whisk together all-purpose flour, sugar, baking powder, and salt in a large bowl.
Mix batter
- Beat egg, milk, vegetable oil, and vanilla extract in a separate bowl until combined.
- Pour the wet ingredients into the dry ingredients and stir until just moistened.
- Gently fold in fresh rhubarb, finely diced.
Bake
- Divide batter among muffin cups, filling each about 2/3 full, then sprinkle with cinnamon sugar for topping.
- Bake for 18-20 minutes at 400°F until golden and a toothpick comes out clean.
Cool
- Cool the muffins in the pan for 5 minutes before transferring to a wire rack.
Notes
For the most tender muffins, stir the batter only until the dry flour disappears—overmixing toughens quick breads. Store airtight at room temperature up to 2 days or refrigerate up to 5 days; freeze up to 2 months. For a lighter option, swap some of the vegetable oil for an equal amount of unsweetened applesauce if you prefer.
