Tender, bakery-style cranberry orange muffins bursting with tart cranberries and bright citrus, topped with crunchy sugar and an optional orange glaze.
Preheat oven to 400°F. Line a 12-cup muffin tin with paper liners or lightly grease.
In a large bowl, whisk flour, granulated sugar, baking powder, baking soda, salt, and orange zest until well combined.
In a separate bowl, whisk eggs, buttermilk, orange juice, and vanilla. Slowly whisk in melted butter until smooth.
Pour wet ingredients into dry and stir gently just until a few streaks of flour remain. Fold in cranberries; do not overmix.
Divide batter evenly among muffin cups. Sprinkle tops with turbinado sugar if using.
Bake 16 to 18 minutes, or until muffins are golden and a toothpick inserted in the center comes out clean.
Cool in the pan for 5 minutes, then transfer to a wire rack to cool slightly.
For the optional glaze, whisk powdered sugar with orange juice until smooth and drizzle over warm or cooled muffins.
Notes
For extra orange flavor, increase zest to 2 tablespoons. If using frozen cranberries, do not thaw; toss them in directly. Store muffins airtight at room temperature for up to 2 days, or freeze up to 2 months.
