2 cups rhubarb – trimmed and chopped into 0.5-inch pieces
2 tbsp turbinado sugar – for topping
Instructions
Preheat the oven to 400°F. Line a 12-cup muffin tin with paper liners or lightly grease the cups.
In a large bowl, whisk together the flour, granulated sugar, baking powder, baking soda, and salt until well combined.
In a separate bowl, whisk the eggs, buttermilk, vegetable oil, and vanilla until smooth.
Make a well in the dry ingredients and pour in the wet mixture. Stir gently with a spatula until just combined; the batter should be slightly lumpy with no dry pockets.
Fold in the chopped rhubarb gently until evenly distributed.
Divide the batter evenly among the muffin cups, filling each about 3/4 full.
Sprinkle the tops with the turbinado sugar.
Bake until the muffins are risen and golden and a toothpick inserted in the center comes out clean or with a few moist crumbs, 18–22 minutes.
Cool in the pan for 5 minutes, then transfer the muffins to a wire rack to cool further. Serve warm or at room temperature.
