Grapefruit curd stuffed doughnuts! Traditional fried yeasted doughnuts filled with a homemade tart grapefruit curd.

These Grapefruit Curd Stuffed Doughnuts are time-intensive, but well worth the effort.

These are authentic fried yeasted doughnuts, prepared with a dough made from warm water, bread flour, active dry yeast, salt, sugar, eggs, and melted butter.
The doughnuts are soft and doughy. Once fried, they’re dusted in granulated sugar and stuffed with a tart and creamy homemade grapefruit curd.

Ingredients
Doughnut Dough:
- 10 ounces (300 mL) warm water
- 1½ tablespoons active dry yeast
- 4¼ cups (540g) bread flour divided
- 2 large eggs
- 2 ounces (55g) unsalted butter melted
- ⅓ cup + 2 tablespoons (90g) granulated sugar
- 1¾ teaspoons kosher salt
Grapefruit Curd:
- 1 cup fresh grapefruit juice
- ⅔ cup (130g) granulated sugar
- 3 tablespoons cornstarch
- 3 large egg yolks
- 2 large eggs
- pinch kosher salt
- 1½ tablespoons cold unsalted butter
- ¼ teaspoon pure vanilla extract
Assembly:
- 8 cups vegetable oil for frying (roughly 8 cups)
- 1-1½ cups granulated sugar for rolling
Instructions
- Prepare Doughnut Dough: Combine warm water, yeast, and a pinch of the granulated sugar in a large mixing bowl. Allow to proof for 5 minutes in a warm place until foamy.
- Add roughly 1 cup of the bread flour and mix well. Allow mixture dough to sit for 30 minutes, uncovered, in a warm space. Add the eggs, remaining sugar, salt, and melted butter and mix well. Add the remaining bread flour, stirring with a large wooden spoon or your hands until well incorporated.
- Transfer the dough onto a well-floured countertop and knead until soft, smooth and well incorporated. The dough will be sticky, but avoid adding too much additional flour. Place the dough in a clean, lightly oiled bowl, cover tightly with plastic wrap, and allow to rest in a warm place until double in size, roughly 1 hour. Meanwhile, prepare the curd (see recipe below).
- Once the dough has doubled in size, place on a lightly oiled countertop and press or roll the dough flat until it is roughly ¾-inch thick. Using a 3-inch biscuit cutter, cut the doughnuts and place each piece of dough on a small square of parchment paper. Cover the doughnuts with a kitchen towel and allow to rest for 15 minutes before frying.
- Prepare Grapefruit Curd: Combine the grapefruit juice, sugar, cornstarch, egg yolks, whole eggs, and salt into a small saucepan. Whisk to combine. Place over medium-low heat and whisk continuously until the mixture thickens and comes to a slow boil. Boil for 2 minutes - this will cook the cornstarch through - before removing from heat. Whisk in the cold butter and vanilla extract.
- Strain the curd through a fine-meshed sieve set over a large bowl. Use a spatula to press the curd through the sieve. Allow the curd to cool completely (if peparing in advance, cover and refrigerate, beating well before using).
- Fry and Serve Doughnuts: Heat vegetable oil (roughly 8 cups) in a large Dutch oven until the temperatures reaches 350°F (175°C). Fry 2 to 3 donuts at a time, inverting the parchment paper and setting the doughnut into the oil until the parchment releases. Fry for 2 to 3 minutes on each side, flipping with a slotted spoon or skimmer, until golden brown on both sides. Transfer the fried doughnuts to a paper-towel lined sheet pan and allow to cool until just slightly warm to the touch.
- Place a thin layer of granulated sugar on a small baking sheet or plate. Transfer the curd to a piping bag fitted with a round tip. Toss the cooled donuts in granulated sugar until well coated on each side. Use a pairing knife, puncture the side of each doughnut to form a small hole. Place the tip of the piping bag into the hole and pipe 1 to 2 teaspoons of grapefruit curd inside (roughly). Serve immediately.

These sound amazing! Can I just eat these every day for breakfast?
Haha! Thank you!!!
I don’t really like grapefruit, but your donuts look luscious! Light and fluffy with a creamy filling. Nommm…. Pinning!
Laura, these doughnuts look incredible! I love citrus curd and I bet grapefruit curd is wonderful. I’ve made fried doughnuts before, and you’re right, it isn’t all that bad once you get going. However, I ended up making about 4 batches in one week because I didn’t want to waste the oil. I had a lot of happy friends that week though. 😉
PS. Your new blog design is lovely!
Good strategy!! I have the oil in the pantry (waiting for a future recipe), but multiple batches of homemade donuts in a week sounds like a much better plan 😉 So glad you like the new design, Amanda!
I’m crazy about curd, but never made it with grapefruit. Amazing! I already left a comment in the previous post, but there’s no harm is saying it again, you’re new look is so perfect Laura, slick and simple! Love it. And these doughnuts…!
Oooh…grapefruit curd, and in a doughnut? Wow! (The fact that this recipe incorporates grapefruit *actually* makes this a healthy doughnut, riiight?)
Oh yessss. Totally. 🙂
I. Love. These. Oh my gosh, seriously, I can’t even express. They remind me of my absolute favorite stuffed doughnuts in the world, malasadas — but maybe even BETTER? I love the idea of grapefruit curd. It sounds like the exact right tang to balance out the heaviness of a deep-fried doughnut. Fantastic, Laura — and love your site redesign!
Oooohhh…masaladas sound amazing. Thanks so much Cynthia! xo
I’m always a bit afraid of trying to make donuts but I can see that they aren’t all that tricky … like you I’m always a bit put off by the deep frying, but the way you describe it makes it feel not so bad.
Congrats on the new design – sooo classy!!
I totally know what you mean–it sounds intimidating, but it just requires a little more work.
So happy to hear you like the new design! Thanks for the feedback!
i never had grapefruit curd but i love grapefruits and doughnuts. looks delish!
Love your new design. It has a nice crisp, natural feel to it. And these donuts are calling my name!
So glad you like it Julie!
First of all – my jaw dropped when I saw the new site. GORGEOUS. I’m in love.
Donuts are definitely required for celebration. And if I don’t have these in my morning, there is a real possibility I might cry.
Oh my god!!! That makes me so happy–so glad to hear you like it.
And I wish I could send you some, but someone (ahem, Connor) demolished them.
UMMM….Con is such a lucky guy! Those donuts….are they for real?!
Congrats! The blog looks great. And so do these donuts. The curd sounds amazing too.
So happy to hear that you like it Norma! Thanks for all of your support!
