Strawberry jam filled donuts haunted my childhood bakery memories. They always promised warm fruit but delivered mostly greasy, hollow disappointment. Most homemade versions turn out dense, raw in the center, or soggy from jam seeping through the crust. This recipe fixes that with a brioche dough and a cornstarch-thickened filling.
Here’s what you’ll get: a two-rise method for the lightest crumb, a jam that stays put instead of running out, and frying temperature tricks for a golden, crackly exterior.

The Secret to the Best Strawberry Jam Filled Donuts
The foundation of any great donut is the dough, and for strawberry jam filled donuts, a brioche-style base is the absolute gold standard. Standard donut dough can turn out a bit bread-like, but brioche introduces butter, milk, and eggs into the mix. This creates a dough that is soft, rich, and slightly sweet. It fries up into a pillowy cloud that contrasts beautifully with the bright, tangy jam. You want a dough that is hydrated but still manageable. If it feels too sticky to handle, resist the urge to dump in extra flour. A little oil on your hands works wonders during the kneading process.
When making the dough for your strawberry jam donuts, temperature control is everything. Warm milk activates the yeast, but if the milk is too hot, it kills the yeast instantly. Aim for around 105 to 110 degrees. The milk should feel like a warm bath, not a hot cup of tea. Once the yeast blooms and foams, you know it is alive and ready. You will combine this with bread flour or all-purpose flour, a bit of sugar, and salt. Bread flour gives a slightly chewier texture that holds up well to filling, while all-purpose flour creates a more tender bite. Both work, so use what you have on hand.
The butter must be soft and at room temperature. You will add it gradually after the initial flour mixture comes together. If you add cold butter, it breaks the gluten strands you are trying to build. As you knead, listen to the dough. It should slap the bowl rhythmically if using a stand mixer. This physical action builds the strong gluten network required to trap the air bubbles produced by the yeast. Without this network, your homemade strawberry jam donuts will collapse during frying.
Proofing the dough requires patience. The first rise takes about an hour in a warm, draft-free spot until it doubles in size. After rolling and cutting, the second proof is equally important. This is where the dough develops its final airy structure. If you skip the second proof, the donuts will be dense and heavy. You will know they are ready when they look puffy and a gentle press leaves a slight indentation that slowly springs back.

Golden, Pillowy Strawberry Jam Filled Donuts
- Total Time: 185 min
- Yield: 12 servings 1x
Description
These homemade donuts feature a rich brioche dough that fries up golden and pillowy, filled with a thick, cornstarch-thickened strawberry jam that stays put instead of running out.
Ingredients
For the brioche dough:
1 cup warm milk (105 to 110 degrees)
2 and 1/4 teaspoons active dry yeast (1 packet)
1/4 cup granulated sugar
3 cups all-purpose flour
4 tablespoons unsalted butter (softened, room temperature)
2 large eggs (room temperature)
1 teaspoon salt
2 quarts canola oil (for frying)
For the strawberry filling:
2 cups fresh strawberries (hulled and chopped)
1/3 cup granulated sugar
1 tablespoon cornstarch
1 tablespoon cold water
For the coating:
1 cup granulated sugar
Instructions
1. Combine the warm milk, yeast, and a pinch of sugar in a small bowl. Let it sit for five minutes until it becomes frothy and smells like fresh bread.
2. In a stand mixer, combine the flour, remaining sugar, and salt. Add the yeast mixture, eggs, and softened butter. Knead the dough on medium speed for eight minutes until it becomes smooth, shiny, and elastic.
3. Transfer the dough to a lightly oiled bowl, cover it with a damp towel, and let it rise in a warm spot for one hour until doubled in size.
4. Gently punch down the dough and turn it out onto a floured surface. Roll the dough to a half-inch thickness and cut out twelve circles using a biscuit cutter.
5. Place the cut donuts on a floured baking sheet, cover loosely, and let them proof for forty-five minutes until puffy and slightly risen.
6. While the donuts proof, combine the chopped strawberries, sugar, cornstarch, and cold water in a saucepan. Cook over medium heat, mashing the strawberries slightly, until the mixture boils and thickens. Let it cool completely.
7. Heat the canola oil in a heavy pot to 350 degrees. Carefully fry the donuts in batches for ninety seconds per side until deep golden brown, then drain on a wire rack.
8. Roll the warm donuts in granulated sugar to coat the exterior while they are still slightly sticky.
9. Once the donuts are completely cool, pipe the thickened strawberry filling into the center of each donut using a piping bag fitted with a small round tip.
Notes
Store in the refrigerator for up to 3 days or freezer for up to 1 month. Reheat at 350°F for 5 minutes.
You can substitute store-bought strawberry jam by whisking a half teaspoon of cornstarch into the cold jam to stabilize it.
Keep the oil temperature steady at 350 degrees to prevent greasy donuts.
Do not skip the second proofing step or the donuts will be dense.

Preparing the Ultimate Strawberry Jam Filling
The filling is the heart of these strawberry jam filled donuts. You can use store-bought strawberry jam, but making a quick homemade filling gives you control over the sweetness and the texture. The biggest problem with using straight jam is that it becomes thin and runny when heated during frying, often leaking out and leaving a hollow donut. To fix this, we add a touch of cornstarch to the jam. This thickens it just enough so it stays suspended in the dough.
To make the filling, combine fresh strawberries, granulated sugar, and a tablespoon of cornstarch in a saucepan. Cook it over medium heat until the strawberries break down and the mixture bubbles. You will see the color deepen from pale pink to a rich, ruby red. The cornstarch needs to reach a boil to fully activate its thickening power. Once it coats the back of a spoon, remove it from the heat and let it cool completely. If you fill the donuts with hot jam, it will melt the raw dough and cause a mess.
Cooling the filling is a critical step for your strawberry filled doughnuts. As it cools, the pectin in the strawberries and the cornstarch work together to create a sturdy, gel-like consistency. When you bite into the finished donut, the filling will hold its shape instead of gushing out onto your shirt. If you prefer to use store-bought jam for convenience, choose a high-quality brand with real fruit and minimal added sugar. You can still whisk a half teaspoon of cornstarch into the cold jam to stabilize it before piping.
Getting the filling consistency right is what separates a good jelly donut from a great one. The filling should be thick enough to pipe through a pastry tip but soft enough to squish when you bite into the donut. For a different take on fruit fillings, check out this peach turnover filling recipe.
Frying and Assembling Your Strawberry Jam Doughnuts
Frying can intimidate home cooks, but it is just a matter of watching the thermometer. The oil temperature for strawberry jam filled donuts needs to be steady at 350 degrees. Use a deep, heavy-bottomed pot and a candy thermometer. Fill the pot with at least two inches of a neutral oil, like canola or vegetable oil. If the oil is too hot, the outside of the donut burns before the inside cooks. If it is too cool, the dough absorbs oil like a sponge and becomes greasy.
Carefully lower the proofed donuts into the oil, working in batches to avoid crowding the pot. Crowding drops the oil temperature drastically. Fry them for about one and a half minutes per side. You will see the edges turn a deep golden brown. Use a slotted spoon to flip them gently. The sound of frying will start loud and frantic, then quiet down as the moisture decreases. Once both sides are golden, lift them out and let them drain on a wire rack set over a baking sheet.
While the donuts are still warm but not hot, roll them in a bowl of granulated sugar. The slight residual warmth helps the sugar adhere to the surface, creating a sweet, crunchy crust that contrasts the soft dough. Let the donuts cool completely before filling. If you try to fill them while they are hot, the jam will melt and seep out of the hole. To fill, use a piping bag fitted with a small round tip. Poke the tip into the side of each donut and squeeze gently. You will feel the donut get heavier as the jam fills the empty space inside.
If you want a different fruit filling, you could try a strawberry rhubarb pie filling for a tart twist. When making these strawberry jam doughnuts, watch for the visual cues of oil readiness. The surface will shimmer but not smoke. Your senses are your best tools here.
Perfecting the Dough and Avoiding Common Mistakes
Even experienced bakers face challenges with strawberry jam filled donuts. One common mistake is handling the dough too roughly. Punching down the dough too aggressively after the first rise knocks out all the air pockets you worked so hard to build. Gently press the gas out with your fingertips instead. When rolling the dough, use even pressure. If the dough is too thin, the jam will burst through during frying.
If your dough tears easily, it needs more time to rest. Cover it and let it relax for ten minutes. The gluten needs time to unwind, making it easier to roll without snapping back. Another frequent issue is donuts deflating when they hit the oil. This usually means the dough is over-proofed. If the donuts look airy and fragile, fry them immediately. Do not let them sit out too long after their second rise.
Measuring flour correctly is vital for the best strawberry jam donuts. Spoon the flour into your measuring cup and level it off with a knife. Dipping the cup directly into the flour bag packs it down, adding too much flour and resulting in a dry, dense donut. A digital kitchen scale is the most accurate tool. 500 grams of flour is always 500 grams, whereas cups can vary by several tablespoons.
The environment plays a big role in yeast dough. In winter, proofing dough takes longer because the kitchen is colder. You can create a warm spot by turning your oven on for one minute, then turning it off. Place the covered bowl inside. The ambient heat provides the perfect proofing temperature. For a delicious way to use extra strawberries, try making strawberry rhubarb sauce. Remember that practice makes perfect with donuts. Your first batch might not look like bakery perfection, but they will still taste incredible.
