Ingredients

Donut Dough:

2¼ cups bread flour – This gives the donuts their lovely texture.
1 large egg (room temperature) – Room temperature eggs help with even mixing.
¼ cup granulated sugar – Just enough sweetness to balance the tart lemon curd.

1 teaspoon salt – Enhances the flavors.
2¼ teaspoons active dry yeast (1 packet) – The magic ingredient for fluffy donuts!
½ cup warm milk (105-115°F) – Not too hot, not too cold – just right for activating the yeast.
⅓ cup unsalted butter, melted and cooled – Adds richness and flavor.

Vegetable oil, for frying – Use a high-heat oil with a neutral flavor.

Lemon Curd Filling:

½ cup lemon juice (about 3 large lemons) – Freshly squeezed is best for the most vibrant flavor.
1 cup granulated sugar – Sweetness to balance the tartness of the lemons.

4 large eggs – These are the key to a creamy, luscious curd.
⅓ cup unsalted butter, cut into cubes – Adds richness and helps create a smooth texture.
Zest of 1 lemon – Adds an extra layer of lemon flavor and fragrance.

Coating:

2 cups granulated sugar – For a classic, sweet coating.

How to Make It

Let’s get baking! This might seem like a lot of steps, but trust me, it’s easier than it looks.

Make the Donut Dough: In a large bowl, combine the warm milk and yeast; let stand for 5-10 minutes until foamy. This is how you know your yeast is alive and kicking! Add the egg, sugar, and salt; whisk until combined. Gradually add the flour, mixing until a shaggy dough forms. Stir in the melted butter; knead for 5-7 minutes until the dough is smooth and elastic. I like to use a stand mixer for this part, but you can definitely knead by hand.

Make the Lemon Curd: In a medium saucepan, whisk together the lemon juice, sugar, and eggs. Cook over medium-low heat, whisking constantly, until the curd thickens (about 8-10 minutes). Don’t let it boil! Remove from heat; stir in the butter and lemon zest until melted and smooth. Strain through a fine-mesh sieve to get rid of any lumps. Press plastic wrap directly onto the surface of the curd to prevent a skin from forming, and refrigerate until chilled.
Fry the Donuts: Punch down the dough and roll it out to ½ inch thickness. Use a 3-inch donut cutter to cut out the donuts. Heat the vegetable oil to 375°F (190°C). Fry the donuts in batches for 1-2 minutes per side, until they are golden brown. Remove and drain on a wire rack.
Fill and Coat the Donuts: Once the donuts have cooled slightly, fill them with the chilled lemon curd using a piping bag or a ziplock bag with a corner snipped off. Toss the filled donuts in the granulated sugar while they are still a little warm, so the sugar sticks nicely.

Serve: Serve your homemade lemon curd donuts immediately and enjoy!

Substitutions & Additions

Feel free to experiment! Want a different citrus twist? Try lime curd! Add a sprinkle of poppy seeds or a drizzle of glaze for extra flair.

Tips for Success

Don’t overcrowd the pan when frying the donuts – this will lower the oil temperature and result in soggy donuts.

Make the lemon curd ahead of time – it tastes even better the next day!
Let the donuts cool completely before filling them, or the curd will melt.

How to Store It

Store leftover donuts in an airtight container at room temperature for up to 2 days. The lemon curd will keep in the refrigerator for up to a week.

FAQs

Q: Can I use a different type of flour? A: Bread flour is best for this recipe, but all-purpose flour can be substituted.

Q: What if my yeast doesn’t foam? A: Make sure your milk is the correct temperature (105-115°F). If it’s too hot, it will kill the yeast. Try a fresh packet of yeast.

Q: Can I make the donuts ahead of time? A: You can fry the donuts ahead of time and store them in an airtight container. Fill and coat them just before serving.
