To make jelly filled doughnuts at home, fry plain yeast doughnuts, let them cool just enough to handle, then push seedless fruit jam into the side of each one with a piping bag fitted with a narrow metal tip. A filling gun is not necessary. A zip-top bag with one corner snipped off does the same job, and the whole job takes around three hours, most of it spent waiting for dough to rise.
There are really three routes, and the differences matter. Injecting the jelly after frying gives you the cleanest result and lets you control how much goes in each doughnut. Wrapping a frozen blob of filling in raw dough and frying the whole thing saves the injection step entirely but gives you less control and a seam that can split in the oil. Piping jam into store-bought baked doughnut holes takes ten minutes and is the version most people make for a party table.
This guide covers the injection method properly, including the equipment you actually need, the temperature and timing numbers that decide the outcome, and what to do when a doughnut bursts, leaks or comes out doughy in the middle.

What You Need
Beyond the doughnuts and the jam, two pieces of kit do most of the work: something that holds the filling under pressure, and a thermometer. Everything else you probably own already.
For the filling, a piping bag with a narrow round metal tip gives the most control. A clean squeeze bottle works nearly as well. A zip-top freezer bag with a 1/4-inch corner snipped off is the improvised version, and a syringe from the kitchen drawer is the one nobody expects but plenty of bakers use. A paring knife makes the hole and a thin wooden skewer clears a jam that has started to clog the tip.
For the dough, you need all-purpose flour, active dry or instant yeast, warm milk, granulated sugar, a couple of egg yolks, softened butter, and a small amount of salt. The yolks and the butter are what turn a plain fried bun into the enriched, almost brioche-like doughnut people mean when they say bakery jelly doughnut.
For the fry, a heavy pot with 4 to 5 inches of oil works better than a shallow skillet because the doughnuts need room to float and turn. A wire skimmer or a slotted metal spoon, a cooling rack set over a baking sheet, a 3-inch round cutter or the lid of a wide jar, a rolling pin, and instant-read thermometer round out the kit.
- Piping bag, narrow round tip: even portions and a tidy seal. The tip must be narrow, because a wide one floods the doughnut.
- Squeeze bottle: fast filling of a big batch, but you cannot see how much has gone in.
- Zip-top bag, corner snipped: no equipment at all. Cut the hole before you fill the bag, not after.
- Syringe: precise filling of small holes, though the filling cools and thickens as it sits.
- Paring knife: making the opening. Rotate the doughnut rather than sawing straight in.
The one piece of equipment I would not skip is the thermometer. Bread doughnuts with oil below 350°F (175°C) soak up fat and stay doughy in the center, and oil above 365°F (185°C) browns the outside before the middle cooks.
Step-by-Step: How to Make Jelly Filled Doughnuts
- Activate the yeast. Warm 1/2 cup of milk to about 110°F (43°C). Stir 2 teaspoons of active dry yeast and 1 teaspoon of sugar into it, wait 5 minutes, and use the mixture if it has foamed. Instant yeast skips the wait entirely.
- Mix the dough. Combine 4 cups of all-purpose flour, 1/3 cup of sugar, 1 teaspoon of salt, the activated yeast, 2 egg yolks, 4 tablespoons of softened butter and enough of the remaining milk to bring it to a soft, slightly tacky dough.
- Knead for 8 to 10 minutes. Push the dough away with the heel of your hand, fold it back, quarter turn. You are looking for a smooth, slightly elastic ball that springs back when you poke it.
- Cover and let it rise for about 1 hour, until doubled. A warm corner of the kitchen speeds this up; a cold one stretches it to two hours.
- Roll and cut. On a lightly floured surface, roll the dough to 3/4 inch thick. Cut with a 3-inch round cutter or a raised doughnut cutter, which gives you a taller finished doughnut and a larger center. A raised cutter running about 3 inches wide can turn a batch that would have made 10 rings into 18.
- Proof the rounds again, 30 to 45 minutes, until puffy. Cover them so they don’t skin over.
- Heat the oil. Set your heaviest pot on a burner and bring the oil to 350 to 365°F (175 to 185°C). A heavy pot holds temperature better than a thin skillet.
- Lower the doughnuts away from you, two or three at a time. Use a slotted spoon and slide them in rather than dropping them from height. Crowding the pot drops the temperature and gives you greasy doughnuts.
- Fry for about 2 to 3 minutes per side. Turn when the underside is golden and the doughnut has risen noticeably, which is the fryer spring. A thermometer pushed into the center should read roughly 190°F (88°C).
- Drain on a rack, not on paper towels. A rack keeps the underside crisp. Roll the still-warm doughnuts in granulated sugar or dust them with powdered sugar.
- Cool for 10 to 20 minutes. Filling a doughnut straight out of the oil melts the jelly and pushes it back out. Let it warm enough to compress easily, cool enough to hold its shape.
How to Prepare the Jelly Filling for Jelly Filled Doughnuts
Use a smooth, seedless jam. Seeds snag the tip halfway through a doughnut, and you end up pulling the tip out and starting over with a hole that is bigger than it should be. Thick fruit preserves hold their shape when the doughnut sits for a while; loose liquid jelly runs and leaks, so strain it or reduce it on the stove until it coats the back of a spoon.
Stir the jam first so any sugar settles at the bottom of the jar, then transfer it to the bag or bottle. If it is so stiff it will not move through a narrow tip, warm the jar in a bowl of hot water for five minutes. Do not boil the jam; a boil thins it and pushes the pectin past the point where it sets again.
Fill a bag with a small amount at a time. A full bag of cold jam is hard to control, and any air pocket in there turns into a pocket of nothing when you squeeze.
How to Fill the Doughnuts Without a Filling Gun
Here is the technique that works, and it works with any of the four tools listed above. Hold the doughnut in one hand with the plain side facing up. Insert the tip from the side near the equator, at a shallow angle, and stop when you feel the tip cross into the hollow center. Do not push to the other side, or you will make a second hole and the filling will run straight through.
Squeeze slowly and continuously. The doughnut visibly swells and starts to feel heavier in your hand as the center fills, and that weight is your best signal. Stop when it feels full, before you can see jelly at the opening. Squeeze once more and lift the tip out slowly, twisting it as you withdraw so the tip doesn’t drag jelly out with it.
Roll the opening gently between your thumb and forefinger to pinch the dough shut around the hole. The seal matters more than the amount of jam. A tidy pinch keeps the filling where you put it; a torn opening lets it ooze out overnight.
Expect to use 1 to 1.5 tablespoons of jam per doughnut. A 12-ounce jar handles about ten standard doughnuts, and a wide ring doughnut can take twice that before it starts to split.
One more route is worth knowing. Home bakers freeze blobs of Nutella in small portions, wrap raw dough around the frozen center, then proof and fry the whole thing. It works and it removes the injection step, but the filling spreads to the seam, and the doughnut is more fragile going into the oil.
How to Check the Fill and Finish
Flip one doughnut and weigh it in your palm against an unfilled one from the same batch. A properly filled doughnut is noticeably heavier without feeling sodden. If you can see a small glossy point of jam at the opening, that is the level most bakers aim for, a fraction overfilled but not splitting.
If one leaks while you work it, let it sit for a minute, then push a little extra dough around the opening with a fingertip and chill that doughnut separately. Warm jam and a warm doughnut are the two causes of nearly every leak, so a few minutes in the freezer fixes most of them.
Chill the finished batch for 15 minutes before serving. The jelly firms slightly, the powdered sugar stays bright, and the crumb inside stops steaming. Jelly filled doughnuts are best the same day, within about 12 hours of frying.
For storage, refrigerate unfilled doughnuts in an airtight container and fill them the next morning. Filled doughnuts keep about two days refrigerated. Freeze unfilled doughnuts flat for up to a month and fill from frozen, letting them sit at room temperature for 20 minutes first. A 25-second microwave run brings back the softness.
Common Mistakes
- Doughnuts are doughy and greasy in the center. The oil was too cool, the pot was crowded, or the doughnuts sat in the oil too long on one side. Hold 350 to 365°F (175 to 185°C), fry two or three at a time, and check the center with a thermometer at 190°F (88°C).
- A doughnut bursts and sprays oil. This is fryer spring, and it comes from dough that has over-proofed or from oil that is too hot. Rise until doubled and no more, and lower each doughnut gently with a spoon instead of dropping it.
- The doughnut tears apart when you lower it in. The surface is sticky and fragile after the second rise. Proof the cut rounds on individual squares of lightly greased parchment, then slide each one off the paper into the oil and pull the parchment out with the spoon.
- Seeds or fruit pieces clog the tip. Switch to seedless jam, or pass the jam through a fine sieve before it goes in the bag. If it clogs mid-doughnut, push the wooden skewer through the tip while the bag is still in your hand.
- Filling leaks out the bottom or the side. You filled too much, the doughnut was still hot, or you pushed the tip through to the far side. Stop at 1 to 1.5 tablespoons, fill doughnuts that have cooled 10 to 20 minutes, and pinch the opening shut.
- The dough barely rises. Either the yeast was dead, killed by salt or by water hotter than 120°F (49°C), or the dough was under-proofed. Warm your milk to about 110°F (43°C), add the salt after the flour is mixed in, and give the first rise until it has genuinely doubled.
One safety note on the frying. Fill your heaviest pot no more than halfway with oil, keep the handles dry and turn them inward, keep a lid and a metal spoon next to the burner, and never pour water into hot oil. Let the oil cool completely before you move it or pour it away.
And a note on names, since it comes up at Hanukkah: jelly doughnuts filled with jam are sufganiyot, the Jewish Hanukkah doughnut. The dough is usually richer and rolled in sugar after frying, but the filling technique is the one described above.
Frequently Asked Questions
What kind of jelly is best for jelly filled doughnuts?
Seedless jam is the best choice, because a narrow piping tip clogs on fruit seeds and skins. Thick fruit preserves also work well since they hold their shape if the doughnut sits for a few hours. Avoid thin liquid jelly, which runs and leaks, and if you only have that, strain it or simmer it until it coats the back of a spoon.
Do I need a filling gun to make jelly doughnuts?
No. A filling gun is a restaurant shortcut. A piping bag with a narrow round tip gives you the most control, a squeeze bottle is faster for large batches, and a zip-top freezer bag with a 1/4-inch corner snipped off works just as well for a dozen doughnuts. A kitchen syringe also works for filling very small holes precisely.
Should the jelly be warm or cold when it goes into the doughnut?
Room temperature, and the doughnut should be cool enough to handle rather than straight from the oil. Warm jam and a hot doughnut are the two main reasons filling leaks back out. If your jam is too stiff to move through the tip, stand the jar in hot water for five minutes rather than boiling it, since boiling thins the jam.
How full should each doughnut be?
About 1 to 1.5 tablespoons of jam, and stop when the doughnut feels heavier in your hand. A small glossy point of jam showing at the opening is the usual target. A 12-ounce jar fills roughly ten standard doughnuts, and a wide ring doughnut can hold twice that before the shell splits and the filling runs out.
Can jelly filled doughnuts be made ahead of time?
Yes, and the smartest version is to fry the doughnuts and fill them the next morning. Unfilled doughnuts keep in an airtight container, and you can freeze them flat for up to a month, then fill from frozen and let them sit at room temperature for 20 minutes before serving. Already filled doughnuts stay good about two days refrigerated.
Why does the jelly leak out of the doughnut?
Three causes account for nearly every leak: too much filling, a doughnut that was still hot, and a tip pushed through to the far side so the jam has a clear exit. Use less jam, let the doughnuts cool for 10 to 20 minutes first, and stop the tip when it enters the hollow center. Pinching the opening closed with your fingers also helps.
Start with the two things that decide whether this works: keep the oil between 350 and 365°F (175 and 185°C), and let each doughnut cool for 10 to 20 minutes before you fill it. Load a narrow-tipped bag with seedless jam, push the tip in from the side until it reaches the center, squeeze until the doughnut feels heavy, and pinch the opening shut. That is the whole method for making jelly filled doughnuts, and it is the same one a donut shop uses.
