Ingredients
Main Muffin Batter
- 1 cup all-purpose flour
- 1 cup whole-wheat flour
- 3/4 cup granulated sugar
- 2–1/2 teaspoons baking powder
- 1 teaspoon ground cinnamon
- 1/2 teaspoon baking soda
- 1/2 teaspoon kosher salt
- 1 cup 2% plain Greek yogurt (or sour cream, light or regular)
- 8 tablespoons unsalted butter, melted and cooled slightly
- 2 large eggs
- 1 teaspoon pure vanilla extract
- 1–1/2 cups 1/4-inch diced rhubarb
Cinnamon Sugar Topping
- 3 tablespoons granulated sugar
- 1/2 teaspoon ground cinnamon
Instructions
- Preheat and Prepare Pan: Preheat your oven to 400°F (200°C). Line a 12-cup muffin tin with paper or foil muffin liners for easy removal and cleanup.
- Mix Dry Ingredients: In a medium mixing bowl, whisk together the all-purpose flour, whole-wheat flour, granulated sugar, baking powder, cinnamon, baking soda, and salt until well combined. This helps evenly distribute the leaveners and spices.
- Mix Wet Ingredients: In a large bowl, whisk together the Greek yogurt, melted butter, eggs, and vanilla extract until the mixture is smooth and creamy.
- Combine Wet and Dry Ingredients: Add the dry ingredient mixture to the wet ingredients. Gently stir with a spatula just until the batter is combined; do not overmix. Fold in the diced rhubarb until evenly distributed. The batter will be thick.
- Fill Muffin Cups: Evenly distribute the batter among the prepared muffin cups, mounding it slightly above the rims for tall muffins.
- Make Cinnamon Sugar Topping: In a small bowl, mix the 3 tablespoons granulated sugar and 1/2 teaspoon ground cinnamon until combined. Sprinkle about 1/2 teaspoon over each muffin, gently patting the topping onto the batter with your fingers.
- Bake the Muffins: Bake for 20-22 minutes, or until the muffins are golden brown and a toothpick inserted in the center comes out clean.
- Cool and Serve: Let the muffins cool in the pan for 5-10 minutes, then transfer to a wire rack. Enjoy warm or at room temperature.
Notes
- These muffins taste best the day of or the day after baking for optimal freshness and texture.
- For longer storage, freeze the muffins in an airtight container or zip-top bag.
- If making mini muffins, bake for only 8-10 minutes.
- This muffin base is incredibly versatile–try stirring in raspberries, blackberries, or chopped apples instead of rhubarb.
