How to Make Cinnamon Sugar Donuts
The secret to these incredibly easy homemade donuts lies in a fantastic shortcut: using pre-made puff pastry dough. This eliminates the need for complex yeast doughs or lengthy rising times, allowing you to enjoy fresh donuts with minimal effort. Puff pastry naturally creates a light, airy, and wonderfully flaky texture that, when fried, transforms into a truly exceptional donut experience.
Step-by-Step Guide:
- Thaw and Prepare the Dough: Begin by thawing your puff pastry dough according to the package directions. This is crucial for easy handling. Once thawed, gently roll out the dough on a lightly floured surface. Now, here’s a vital step: brush the entire surface with an egg wash. Do not skip this! The egg wash acts as a binding agent, helping the delicate layers of puff pastry adhere to each other. Without it, your beautiful donuts are at risk of falling apart in the hot oil. It also contributes to that coveted golden-brown finish and subtle richness.
- Fold and Cut: Carefully fold the egg-washed puff pastry sheet back over along its seams. This layering technique helps create even more distinct, flaky layers in your final donut. Next, it’s time to cut out your donut shapes. We recommend using a biscuit cutter set for precision. Use a larger cutter for the main donut shape and a smaller one to create the classic hole in the center. You’ll end up with beautifully shaped donuts and delightful mini donut holes!



When it comes to cooking these pastries, I’ve experimented with both baking and frying, and it comes as no surprise that frying is the undisputed champion. After all, these are donuts, and no one truly expects them to be a health food! Even as a dietitian, I firmly believe in enjoying occasional indulgences exactly as they were intended. Frying transforms the puff pastry into an unbelievably light, crispy, and rich treat that baking simply can’t replicate.
A wonderful aspect of this easy donut recipe is that it yields approximately six donuts, making it the perfect quantity for a small family treat or a cozy gathering without an overwhelming surplus. One critical tip for perfect results: always ensure your frying oil is adequately hot before introducing the donuts. If the oil isn’t hot enough, the donuts will absorb too much grease and turn out dense and soggy – what we affectionately call “hockey pucks.” Aim for a temperature between 350-375°F (175-190°C) for that ideal golden crispness. A candy thermometer is highly recommended for accuracy.



Some might compare these to a cronut, the famous hybrid of a croissant and a donut, known for its buttery, flaky layers. While I haven’t had the pleasure of tasting an authentic cronut myself, I can confidently say that this puff pastry version delivers a similar, utterly delightful experience. No matter what you call them, you are bound to fall in love with these golden, crispy, and incredibly flaky fried treats. Their simplicity and speed make them a perfect indulgence for any occasion.
How to Store Leftover Frying Oil?
A common question when deep-frying at home is what to do with the leftover oil. Properly storing it can save you money and reduce waste, especially if you enjoy making fried foods frequently. Here are a few reliable methods:
- For Immediate Reuse (Deep Frying): If you plan on using the oil again for deep frying within a short period (a few days to a week), the best practice is to first allow it to cool completely. Once cool, carefully strain the oil through a fine-mesh sieve lined with cheesecloth or a coffee filter into a clean, airtight container. This removes any food particles that could spoil the oil. Store the filtered oil in a cool, dark place at room temperature. This method is ideal for oils like canola, vegetable, or safflower that have higher smoke points and are commonly used for frying.
- Refrigerated Storage: For longer storage, you can keep the filtered oil in an airtight container in the refrigerator. This can extend its shelf life by several weeks. However, before using refrigerated oil, it’s essential to let it come back up to room temperature. This ensures that the oil heats evenly and consistently, preventing any cold spots that could negatively impact the flavor and texture of your food. Some oils may solidify in the fridge, which is normal and will reverse once warmed.
Remember, oil can only be reused a certain number of times before it starts to break down and affect flavor. Look for signs like dark color, foaming, or a rancid smell as indicators that it’s time to dispose of the oil.
How to Reheat Leftover Donuts?
While these cinnamon sugar donuts are undeniably best enjoyed fresh out of the fryer, sometimes you might have a few leftovers. Don’t worry, you can easily revive them to a state of deliciousness! The goal is to bring back some of their original warmth and crispness.
- Microwave Method for Softness: For quick warming and a softer texture, place your leftover donuts on a microwave-safe plate. Cover them loosely with a paper towel to absorb any excess moisture and prevent them from becoming chewy. Microwave for about 10 seconds. This short burst of heat is usually enough to warm them through. After microwaving, let them sit for a minute or two to allow the heat to distribute evenly. You can then sprinkle with a fresh dusting of cinnamon sugar or any other topping to refresh their appearance and taste.
- Oven Method for Crispness: If you prefer to restore a crispier exterior, especially for fried donuts, reheating them in the oven is a great option. Preheat your oven to a moderate temperature, around 300°F (150°C). Place the donuts on a baking sheet, ideally on a wire rack to allow air circulation. Heat for 5-7 minutes, or until they are warmed through and the exterior feels slightly crisp again. Keep a close eye on them to prevent burning. Once warm, they are ready to be re-coated and enjoyed.
With these simple reheating tricks, your leftover homemade donuts can still provide a delightful treat, almost as good as the first bite!

Desserts
Donuts
Equipment
- Biscuit or dough cutters
- Large mixing bowl
- Whisk
- Dutch oven or deep sauce pan
6
Ingredients
- 1 box puff pastry
- 1 large egg beaten
- ¾ cup white granulated sugar
- 2 tbsp ground cinnamon
- 3 cup neutral frying oil like canola, vegetable, or safflower
Instructions
- Defrost puff pastry overnight in the fridge or on the counter according to package directions.
- Unroll one sheet of the puff pastry on a lightly floured surface and brush the entire open side with 1/2 of the beaten egg wash.
- Fold the pastry sheet back up along the seams, then repeat with the other sheet of pastry dough.
- Using biscuit or dough cutters, cut out three circles from each sheet of prepared puff pastry, then a smaller hole in the center for the donut hole.
- Whisk together the sugar and cinnamon in a large shallow bowl and set aside.
- Heat the oil in a dutch oven or deep sauce pan over medium-high heat; you want the oil to be 350-375 degrees F. (If you have a candy thermometer, use it for accuracy!)
- Once the oil is ready, carefully fry the donuts (and donut holes!) in batches, being mindful not to overcrowd your pan. The donuts should sizzle immediately upon contact with the oil; if they don’t, your oil is not hot enough. Fry until golden brown on both sides.
- Remove the golden-brown donuts from the oil, allowing any excess oil to drip off briefly. Immediately transfer them to the bowl with the cinnamon sugar mixture and toss to coat thoroughly. Serve immediately! These taste absolutely best right out of the fryer, so don’t hesitate to enjoy them while they’re still warm and fresh.
