Homemade Heart-Shaped Jam Filled Donuts

Heart-shaped jam filled donuts first appeared in my kitchen on a snowy February morning when I wanted to surprise my partner with something more special than store-bought pastries. The smell of warm yeast dough and sweet raspberry filling bubbling through a golden crust created a memory that still makes me smile.

Most homemade filled donuts collapse into greasy, deflated hockey pucks because the oil temperature drops too fast or the dough lacks the gluten strength to hold their shape. This recipe fixes both issues with a structured stand mixer dough and a specific frying method so your donuts stay puffy, crisp, and perfectly round.

Below I walk through the dough science, the frying temperature that actually works, and how to pipe jam without making a mess.

The dough: building structure for perfect hearts

The base for your Heart-shaped jam filled donuts comes down to the feel and temperature of your ingredients. You want a dough that is soft enough to puff beautifully in hot oil, yet strong enough to hold its distinct shape without drooping or distorting. It should feel like a marshmallow but snap back gently when you press your finger into it. This balance comes from properly hydrating your flour and developing the gluten strands fully before you ever touch a rolling pin.

Start by warming your milk to around 100 degrees Fahrenheit. You should be able to hold your finger in it comfortably without flinching. Sprinkle your active dry yeast over the surface of the milk and let it sit for five minutes until it becomes frothy and smells distinctly like fresh bread. This blooming step tells you your yeast is alive and ready to go. If you are using instant yeast, you can skip the blooming and mix it directly into your dry ingredients, but taking this extra minute guarantees an active start.

In the bowl of your stand mixer, combine your warm milk and yeast mixture with slightly softened butter, a couple of large egg yolks, sugar, salt, and a generous pinch of freshly grated nutmeg. The nutmeg is the secret whisper of flavor that makes your kitchen smell like a professional bakery. Add your all-purpose flour and mix on low speed with the dough hook attachment. Let the machine knead the dough for about eight minutes. You are looking for the dough to pull away cleanly from the sides of the bowl while remaining slightly tacky to the touch. If it sticks aggressively, add flour one tablespoon at a time.

Lightly oil a large glass bowl and transfer your smooth dough into it. Cover the bowl tightly with plastic wrap and let it sit in a draft-free spot until it has doubled in size. This first proof usually takes about an hour and a half. You will know it is ready when you poke the dough with a knuckle and the indentation remains without springing back. While you wait, you can prepare your filling. If you love making your own fruit preserves, our rhubarb strawberry jam works beautifully inside these pastries. Or try a bright, tangy blackberry jam for a contrast to the rich dough.

Cutting and proofing your heart shapes

Once your dough has doubled, it is time to shape your Heart-shaped jam filled donuts. Turn the dough out onto a very lightly floured counter. You want just enough flour to prevent sticking, but too much will make the dough slide around and prevent you from getting clean cuts. Press the air out gently with the palms of your hands, then use a rolling pin to flatten the dough into an even layer about half an inch thick. Uniform thickness matters here. If the dough is thicker in the middle, your donuts will fry unevenly and the centers will remain gummy while the edges turn too dark.

Dip your heart-shaped cutter into a little flour and press it straight down into the dough. Do not twist the cutter as you pull it up. Twisting seals the edges of the dough together, which prevents the donuts from rising properly in the fryer. Press down firmly, lift straight up, and transfer your dough heart to a small square of parchment paper. Cutting each donut on its own parchment square is a trick that saves you from having to move the raw dough later. Moving raw, proofed dough with a spatula will deflate it and ruin all your hard work.

Cover your cut donuts loosely with a clean kitchen towel and let them proof a second time. This second proof is what gives you that airy, cloud-like texture inside. Let them rest for about thirty minutes. You will see them puff up slightly and take on a soft, pillowy appearance. Press one very gently with your fingertip. It should leave a faint impression that slowly fills back in.

While the donuts proof, prepare your jam. Spoon your seedless strawberry or raspberry jam into a piping bag fitted with a metal piping tip. You want a tip with a narrow opening so you can insert it cleanly into the side of the donut. If you want to branch out from standard fruit fillings, our jalapeno peach jam offers a sweet and spicy surprise inside a classic pastry shell. Another great option is our peach jam for a delicate summer flavor.

Frying to golden perfection

The frying stage is where homemade Heart-shaped jam filled donuts often go wrong, but a few precise steps will guarantee a crisp, golden crust. Pour vegetable oil into a heavy-bottomed Dutch oven to a depth of about two inches. You need enough oil for the donuts to float freely without touching the bottom of the pot. Clip a deep-fry thermometer to the side of the pot and heat the oil to exactly 350 degrees Fahrenheit. Temperature control is your best friend here. If the oil is too hot, the outside of the donut will burn before the inside cooks through. If the oil drops below 325 degrees, the pastry will absorb the oil and taste heavy.

Pick up a donut by lifting the parchment paper square and gently lowering it into the oil. The paper will detach almost immediately. Do not drop the donuts in by hand, as the impact can cause hot oil to splash. Fry three or four donuts at a time to avoid overcrowding the pot. Overcrowding drops the oil temperature drastically and leads to greasy results. Let them fry for about ninety seconds on the first side. You will see the edges turn a deep golden brown and the donut will puff up dramatically. Use a slotted spider or spoon to flip them over and fry for another ninety seconds on the other side.

Scoop the finished donuts out of the oil and let them drain on a wire rack placed over a baking sheet. Draining on a rack keeps the bottoms crisp. If you drain them on paper towels, the steam gets trapped and creates a soggy bottom. While they are still hot but cool enough to handle, toss them in a bowl of granulated sugar. The residual heat helps the sugar stick to the surface. You get a sweet, crunchy layer that plays off the soft dough underneath. If you prefer a different finish, you can let them cool slightly and dust them heavily with powdered sugar instead. Just like our heart shaped lemon zest cookies, a bright citrus glaze also works well if you want to experiment with the coating.

Filling and serving your donuts

Now comes the most satisfying part of making Heart-shaped jam filled donuts. Take your cooled donuts and use a chopstick or a wooden skewer to poke a hole in the side of each one. Push the skewer gently into the center of the donut to create a small pocket for the jam. Do not poke all the way through the other side. You want to create a tunnel that will hold your filling snugly.

Insert your piping tip into the hole you just made. Squeeze the piping bag gently until you feel the donut grow heavy and see the jam start to push back out of the opening. Stop squeezing immediately. Overfilling will cause the donut to burst and leak jam everywhere. Aim for about one to two teaspoons of jam per donut.

Serve these heart shaped jelly donuts immediately if you want to enjoy the contrast between the warm, sugar-coated dough and the cool fruit filling. If you are making them ahead for a party, you can fry and sugar them the day before, then fill them right before serving to keep the pastry crisp. For a Valentine’s Day dessert spread, these pair well with our white chocolate cranberry heart cookies and a batch of coconut heart shaped macaroons. You can also bake a batch of our heart shaped valentine cookies for a classic buttery option.
