The warm scent of cinnamon and butter melting together transforms a simple morning into something magical. These baked donuts emerge from the oven golden and tender, then get rolled in a cinnamon-sugar coating that clings to every curve. No deep fryer, no mess, no waiting for dough to rise — just soft, cake-like donuts that taste like your favorite bakery opened in your kitchen.
Why You’ll Love This Recipe
- Ready in 30 minutes from start to finish, including baking and coating time
- No special equipment needed beyond a standard donut pan (or a muffin tin works too)
- Stays moist for 2-3 days thanks to the buttermilk and butter in the batter
- Kid-friendly baking project with no hot oil or complicated techniques
- Customizable coating — stick with classic cinnamon sugar or try maple glaze, chocolate, or plain powdered sugar
Pro Tips
- Room temperature ingredients are essential — cold eggs and buttermilk create a lumpy batter that bakes unevenly. Set them out 30 minutes before mixing.
- Fill donut cavities only two-thirds full to prevent the center hole from closing during baking. Use a piping bag or zip-top bag with the corner snipped for precise filling.
- Roll in cinnamon sugar while still warm — the butter coating needs heat to stay sticky. Wait too long and the sugar won’t adhere properly.
- Don’t overbake or they’ll dry out — these are done when a toothpick comes out with just a few moist crumbs, not bone dry. Start checking at 9 minutes.
Homemade Cinnamon Sugar Baked Donuts
Ingredients
Method
- Preheat your oven to 350°F (175°C). Grease a 6-cavity donut pan generously with nonstick spray or butter, making sure to coat the center posts well.
- In a large mixing bowl, whisk together the flour, 1/3 cup sugar, baking powder, baking soda, 1/2 teaspoon cinnamon, and salt until evenly combined with no lumps.
- In a separate medium bowl, whisk the egg until smooth. Add the buttermilk, 2 tablespoons melted butter, and vanilla extract, whisking until fully blended.
- Pour the wet ingredients into the dry ingredients and gently fold with a spatula just until no dry flour remains visible. The batter will be thick but pourable — do not overmix or the donuts will be dense.
- Transfer the batter to a piping bag or large zip-top bag with one corner snipped off. Pipe batter into each donut cavity until two-thirds full, leaving space for rising.
- Bake for 10-12 minutes, until the tops spring back when gently pressed and a toothpick inserted comes out with just a few moist crumbs. Do not overbake.
- Let donuts cool in the pan for 3 minutes, then carefully turn out onto a wire rack. While still warm, brush each donut all over with the 3 tablespoons melted butter.
- In a shallow bowl, mix the 1/2 cup sugar with 1 tablespoon cinnamon. Roll each buttered donut in the cinnamon sugar mixture until fully coated on all sides.
- Serve warm or at room temperature. These are best eaten the same day but will stay moist in an airtight container for 2-3 days.
Frequently Asked Questions
Can I make these without a donut pan?
Yes, use a standard muffin tin to make donut muffins instead. They’ll bake in the same time but won’t have the classic ring shape. You can also bake in a mini muffin pan for donut holes — reduce baking time to 6-8 minutes.
What can I substitute for buttermilk?
Mix 1/2 cup whole milk with 1/2 tablespoon white vinegar or lemon juice. Let it sit for 5 minutes until slightly thickened, then use as directed in the recipe.
How do I prevent the centers from baking closed?
Don’t overfill the cavities, and make sure your batter isn’t too thick. If it seems heavy, thin it with 1-2 tablespoons of buttermilk. A properly filled pan should show a visible center hole throughout baking.
Why are my donuts dense instead of fluffy?
Overmixing the batter develops too much gluten, creating a tough texture. Stir just until the dry ingredients disappear — a few small lumps are fine. Also check that your baking powder is fresh and not expired.
Storage & Serving
Store in an airtight container at room temperature for up to 3 days — they actually stay surprisingly moist thanks to the buttermilk. For longer storage, freeze unfrosted donuts for up to 2 months and coat with cinnamon sugar after thawing. Serve warm for breakfast with hot coffee, pack in lunchboxes as a sweet surprise, or stack on a platter for brunch gatherings. They’re perfect alongside fresh fruit and yogurt for a balanced morning spread.
These donuts prove you don’t need a deep fryer or pastry chef skills to bring bakery magic home — just mix, bake, and roll your way to cinnamon-sugar heaven.
