Step-by-step instructions
Preheat your oven to 375°F (190°C) and prepare a 12-cup muffin tin by greasing or lining it with paper liners.
In a large bowl, combine the flour, sugar, baking powder, baking soda, salt, and ground cinnamon. Whisk until well blended.
In another bowl, whisk together the buttermilk, eggs, melted butter, and vanilla extract until the mixture is smooth.
Gently pour the wet ingredients into the dry mixture and stir until just combined. Be careful not to overmix; a few lumps are perfectly fine.
Evenly divide the batter among the muffin cups, filling each about three-quarters full.
Bake for 15-18 minutes or until a toothpick inserted into the center of a muffin comes out clean.
Meanwhile, mix the 1/4 cup sugar with 1 tablespoon cinnamon in a small bowl for coating.
Once baked, remove the muffins from the oven and let them cool in the pan for about 5 minutes.
While still warm, brush each muffin lightly with the melted butter, then roll them in the cinnamon sugar mixture to coat thoroughly.
Allow the muffins to cool slightly before serving. This helps achieve the best texture!
Best ways to enjoy it
These fluffy cinnamon sugar donut muffins are delicious enjoyed warm on their own, but they can be paired with so many delightful accompaniments! Serve them alongside a hot cup of coffee or tea for a cozy moment. They also shine when paired with fresh fruit, yogurt, or a dollop of whipped cream.

How to store & freeze
To keep your leftover muffins fresh, store them in an airtight container at room temperature for up to 3 days. If you want to save them for later, consider freezing them. Wrap each muffin tightly in plastic wrap and store them in a freezer-safe bag. They will stay fresh for about 2 months. For best results, allow them to thaw at room temperature before enjoying.
Helpful cooking tips
- Be sure to measure your flour correctly by spooning it into the measuring cup and leveling it off for the best results.
- Avoid overmixing your batter to ensure the muffins remain fluffy and tender.
- Experiment with adding chocolate chips or nuts to the batter for additional flavor and texture.
