How to Make Cast Iron Skillet Cinnamon Sugar Donuts: A Quick and Easy Dessert

There's something magical about homemade donuts, especially when they're fried in a cast iron skillet. The heavy pan holds steady heat, giving you those golden, crispy edges and a soft, airy center that store-bought versions just can't match. Best of all, you don't need an oven or deep fryer—just a skillet, a few pantry staples, and about 30 minutes.

This cast iron skillet donuts recipe is designed for beginners and seasoned cooks alike. The dough is simple to mix, the frying is straightforward, and the cinnamon sugar coating makes every bite irresistible. Whether you're planning a weekend breakfast or a quick dessert, these skillet fried donuts will become your new go-to.

Why Cast Iron Is Perfect for Frying Donuts

Cast iron skillets excel at frying because they retain and distribute heat evenly. Unlike thin pans that create hot spots, a preheated cast iron skillet maintains a steady oil temperature, so your donuts cook uniformly without burning. The high sides also keep splatter contained, and the seasoned surface adds a subtle depth of flavor that enhances the dough.

For this recipe, a 10- or 12-inch skillet works best. Field Company's skillets are lighter than traditional cast iron, making it easier to maneuver the pan when swirling oil or lifting out donuts. If you're making smaller donut holes, the No.6 Cast Iron Skillet Lid isn't needed here, but a set like The Minis can be handy for portioning dough into perfect little rounds.

Ingredients for Cinnamon Sugar Donuts

You'll need basic baking staples: all-purpose flour, granulated sugar, baking powder, salt, milk, butter, eggs, and vanilla extract. For the coating, mix cinnamon and sugar in a shallow bowl. For frying, use a neutral oil with a high smoke point, such as vegetable, canola, or peanut oil.

If you'd like to shape the donuts without a cutter, the No.8 Bread Baking Set includes a proofing basket that can double as a template for cutting rounds. But a simple glass and a bottle cap work just as well.

Step-by-Step: Frying Donuts in a Cast Iron Skillet

Start by whisking the dry ingredients together. In a separate bowl, combine milk, melted butter, egg, and vanilla. Mix wet into dry until a soft dough forms. Turn onto a floured surface, pat to 1/2-inch thickness, and cut into rounds with a donut cutter or two concentric circles. If you don't have a cutter, use a 3-inch biscuit cutter for the outer ring and a 1-inch bottle cap for the hole.

Heat about 1 inch of oil in your cast iron skillet over medium heat until it reaches 350°F. Test with a dough scrap—it should sizzle and float. Fry donuts in batches, 2 to 3 at a time, for about 1 minute per side until deep golden brown. Use a slotted spatula or tongs to flip them. The Cast Iron Tools Set is excellent for this: the spatula slides under the donuts easily, and the tongs give you precise control.

Transfer donuts to a paper-towel-lined plate to drain for 30 seconds, then toss immediately in the cinnamon-sugar mixture. The residual heat helps the coating stick. Serve warm—they're best within an hour.

• Keep oil temperature steady: too hot and the outside burns before the inside cooks; too cool and donuts absorb excess oil.
• Don't overcrowd the skillet—lowering the oil temperature leads to greasy donuts.
• For extra fluffy donuts, let the cut dough rest for 10 minutes before frying.

Easy Variations and Serving Ideas

Once you've mastered the basic cinnamon sugar donuts, try swapping the coating: powdered sugar, cocoa powder with sugar, or a quick glaze made from confectioners' sugar and milk. You can also add a pinch of nutmeg or cardamom to the dough for a spiced twist.

These skillet fried donuts are perfect on their own, but you can serve them with a side of hot chocolate or coffee for a cozy treat. If you have leftovers (unlikely!), store them in an airtight container at room temperature for up to a day—reheat briefly in the skillet to revive the crispness.

With just a cast iron skillet and a handful of ingredients, you can whip up homemade donuts in under 30 minutes. The even heat of the pan gives you that perfect golden crust, while the cinnamon sugar coating delivers a sweet crunch every time. Next time a donut craving strikes, skip the bakery and reach for your skillet—this easy donut recipe is proof that the best desserts often come from simple tools and a little practice.
