Whether served for breakfast, as an afternoon snack, or as a dessert, these muffins are a treat that always brings smiles to the table.
Ingredients
2 cups all-purpose flour
1 cup granulated sugar
2 teaspoons baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
1 cup buttermilk
2 large eggs
1/4 cup unsalted butter, melted
1 teaspoon vanilla extract
1 teaspoon ground cinnamon
1/2 cup granulated sugar (for coating)
2 teaspoons ground cinnamon (for coating)
4 tablespoons unsalted butter, melted (for coating)
Directions
Preheat the oven to 375°F (190°C). Line a muffin tin with paper liners or grease it well with butter or cooking spray.
In a large bowl, whisk together the flour, sugar, baking powder, baking soda, salt, and 1 teaspoon cinnamon until evenly combined.
In another bowl, whisk together the buttermilk, eggs, melted butter, and vanilla extract until smooth.
Pour the wet ingredients into the dry ingredients and gently fold with a spatula until just combined. Be careful not to overmix, as this can make the muffins dense. The batter should look slightly lumpy.
Divide the batter evenly among the muffin cups, filling each about three-quarters full.
Bake for 15 to 18 minutes, or until a toothpick inserted in the center comes out clean.
While the muffins bake, mix the 1/2 cup sugar and 2 teaspoons cinnamon in a shallow bowl and set aside.
Once the muffins are done, remove them from the oven and allow them to cool in the pan for 5 minutes.
Brush each warm muffin with the melted butter, then roll in the cinnamon sugar mixture until completely coated.
Allow them to cool slightly before serving to enjoy their fluffy texture and sweet coating.
Serving Ideas
These donut muffins are best enjoyed warm, when the butter and cinnamon sugar coating is fresh and fragrant. They pair perfectly with a cup of coffee, tea, or hot chocolate, making them a cozy morning treat. For a dessert version, serve them with a scoop of vanilla ice cream or drizzle lightly with caramel sauce.
They also make a delightful addition to a brunch spread alongside fruit, yogurt, or other pastries. Their bite-sized, handheld nature makes them easy to serve at gatherings or family breakfasts.
Tips and Tricks
Use fresh buttermilk for the best flavor and texture. The acidity of buttermilk helps create a tender crumb while adding a subtle tang that balances the sweetness.
Brush the muffins with butter while they are still warm so that the cinnamon sugar sticks evenly. If they cool too much, the coating may not adhere as well.
For an extra touch, add a pinch of nutmeg to the batter for a flavor reminiscent of old-fashioned donuts.
Variations
While classic cinnamon sugar is always a winner, you can easily switch up this recipe for new flavors. Try coating the muffins in powdered sugar for a donut-hole style finish, or dip them in a simple glaze made with powdered sugar and milk. If you enjoy chocolate, sprinkle mini chocolate chips into the batter before baking for a sweeter variation.
Storage
These muffins are best enjoyed the same day they are baked, when the coating is fresh and crisp. However, they can be stored in an airtight container at room temperature for up to three days. If storing, you may wish to refresh them by warming briefly in the microwave before serving.
They also freeze well. Allow the muffins to cool completely, then freeze them in a single layer before transferring to a freezer bag. To serve, thaw at room temperature and, if desired, roll them again in a fresh batch of cinnamon sugar after brushing lightly with melted butter.
Final Thoughts
Grandma’s fluffy cinnamon sugar donut muffins are a wonderful example of how simple ingredients can create something special. They combine the soft, tender crumb of a muffin with the sweet coating of a donut, resulting in a treat that feels both comforting and indulgent.
Perfect for mornings, gatherings, or a sweet afternoon pick-me-up, these muffins are a recipe you will return to again and again. With their light texture, warm cinnamon flavor, and nostalgic charm, they are sure to become a family favorite for years to come.
