These Blueberry Buttermilk Muffins have a tender, moist, and slightly tangy crumb with pops of fresh blueberries. They’re also topped with coarse sugar for a bakery-style finish!
Preheat the oven to 400 degrees F. Line a standard 12-count muffin pan with cupcake liners.
Whisk together the flour, sugar, baking powder, baking soda, cinnamon, and salt.
In a separate large bowl, whisk together the buttermilk, oil, eggs, and vanilla until well combined.
Add the dry ingredients to the wet and mix just until combined.
Using a rubber spatula, fold in the blueberries just until they are evenly distributed.
Scoop the muffin batter into the lined muffin pan until each well is about 3/4 full.
Sprinkle each muffin with turbinado sugar or granulated sugar. (see notes)
Bake the muffins for 18 to 22 minutes or until baked through and a toothpick inserted in the center comes out with a few moist crumbs.
Allow the muffins to cool in the pan for 5 minutes then transfer them to a wire rack to finish cooling. Serve completely cooled or still a bit warm.
Notes
To make your own buttermilk, place 1 tablespoon of lemon juice or vinegar in a measuring cup then fill it to the 1 cup line with whole milk. Stir and let sit for 5 minutes or until slightly thickened. Use as directed.
The turbinado sugar on top adds a bit of crunch and extra sweetness. I highly recommend using it but if you don't have any, you can use a bit of regular white sugar instead.
Store the muffins in a paper-towel lined airtight container at room temp for 3 days or in the fridge for up to 5 days.
