Raspberry Chia Jam Heart-Shaped Linzer Cookies Recipe tastes like a buttery shortbread hug with a bright, tangy raspberry center that doesn’t taste overly sweet. This recipe works perfectly for bakers who want a show-stopping cookie in about 1 hour total, including chill time, without fancy tools or pastry school skills. I test these every February for “quality control,” and my neighbors mysteriously appear at my door right when the first batch cools.

Why Raspberry Chia Jam Heart-Shaped Linzer Cookies Recipe Is Worth It

These Raspberry Chia Jam Heart-Shaped Linzer Cookies look bakery-level fancy, yet the dough comes together with simple pantry ingredients and a mixer. The chia jam sets quickly, so you skip the long stovetop simmer and heavy sugar of traditional jam.

The cookies stay tender and crumbly, with a nutty note from almond flour that pairs perfectly with the tart raspberries. They also hold their shape well, so you can pack them in tins, gift boxes, or lunchboxes without ending up with a bag of crumbs.

“I baked these Raspberry Chia Jam Heart-Shaped Linzer Cookies for a family brunch, and everyone assumed I bought them from a high-end bakery. The raspberry chia filling tasted bright and not too sweet, and the cookies stayed tender for three days. My kids now request the ‘heart cookies’ for every holiday, not just Valentine’s Day.”

Ingredients You Need

For the raspberry chia jam

2 cups fresh or frozen raspberries
- Frozen raspberries work great and usually cost less. I often use store-brand frozen berries.
2–3 tablespoons maple syrup or honey, to taste
- Use 2 tablespoons for a tangier jam, 3 tablespoons for a sweeter version.
2 tablespoons chia seeds
- Any brand works; white chia seeds look slightly prettier but black seeds taste the same.
1 teaspoon fresh lemon juice
- Bottled lemon juice works in a pinch, but fresh gives a brighter flavor.
1/2 teaspoon vanilla extract (optional, but lovely)

1 cup (2 sticks / 226 g) unsalted butter, softened to cool room temperature
- I prefer a European-style butter like Kerrygold for extra richness, but any real butter works.
3/4 cup (150 g) granulated sugar
1 large egg, room temperature
1 teaspoon vanilla extract
1/2 teaspoon almond extract
- This gives classic Linzer cookie flavor; skip it if you dislike almond.
2 cups (240 g) all-purpose flour
- Use a good basic brand like King Arthur or Gold Medal for consistent results.
1 cup (96 g) fine almond flour or almond meal
- Blanched almond flour gives a more delicate texture; almond meal adds a slightly rustic look.
1/2 teaspoon fine sea salt
1/4 teaspoon ground cinnamon (optional, but adds warmth)

To finish

1/2–3/4 cup raspberry chia jam (from above)
Powdered sugar, for dusting the tops

Equipment list

Mixing bowls (one medium, one large)
Hand mixer or stand mixer with paddle attachment
Rubber spatula
Small saucepan
Whisk or spoon for stirring jam
Measuring cups and spoons
Kitchen scale (optional, but very helpful for flour and almond flour)
Rolling pin
Heart-shaped cookie cutter (about 2–2.5 inches)
Small heart or round cutter for the “window” (about 1 inch)
Baking sheets
Parchment paper or silicone baking mats
Cooling racks
Fine-mesh sieve for powdered sugar (optional, but pretty)

Quick Tips & substitutions

Chill the dough at least 30 minutes so the cookies hold sharp edges and bake evenly.
Roll the dough between two sheets of parchment to prevent sticking and reduce extra flour.
Use frozen raspberries straight from the freezer; no need to thaw before cooking the jam.
Sweeten the jam with maple syrup, honey, or a sugar-free sweetener that measures like sugar.
Swap almond flour with finely ground hazelnuts or pecans for a twist on the classic flavor.
Use seedless raspberry preserves if you want to skip the chia jam step entirely.
Dust only the top cookies with powdered sugar before assembly to keep the jam layer glossy.
Bake one sheet at a time in the center of the oven for the most even browning.

How to Make Raspberry Chia Jam Heart-Shaped Linzer Cookies Recipe

Step 1: Cook the raspberry chia jam

Add raspberries to a small saucepan and set the heat to medium. Stir as the berries break down and release juices, about 5–7 minutes. Mash them lightly with a fork or spatula until the mixture looks saucy with small bits of fruit.

Stir in maple syrup or honey, lemon juice, and vanilla. Sprinkle chia seeds over the top and stir well so they distribute evenly. Lower the heat and cook 2–3 more minutes while the mixture thickens slightly, then turn off the heat.

Let the jam cool in the pan for 10–15 minutes, then transfer it to a jar or bowl. The chia seeds continue to thicken the jam as it cools. You want a spreadable texture that doesn’t run; if it looks too thin after cooling, stir in another teaspoon of chia seeds and wait 5 more minutes.

In a large bowl, beat the softened butter and granulated sugar with a mixer on medium speed until the mixture looks light and fluffy, about 2–3 minutes. Scrape down the bowl once or twice so no butter hides at the bottom. Add the egg, vanilla, and almond extract, then mix again until the mixture looks smooth and creamy.

In a separate bowl, whisk together the all-purpose flour, almond flour, salt, and cinnamon. Add the dry ingredients to the butter mixture in two additions, mixing on low speed just until the dough comes together. The dough should feel soft but not sticky; if it seems too sticky, sprinkle in 1–2 extra tablespoons of flour and mix briefly.

Step 3: Chill and roll the dough

Divide the dough into two equal portions and shape each into a flat disk. Wrap each disk in plastic wrap or place it in a reusable bag. Chill the dough in the refrigerator for at least 30 minutes, or up to 2 days.

When you feel ready to roll, line two baking sheets with parchment paper. Unwrap one dough disk and place it between two sheets of parchment. Roll the dough to about 1/8–1/4 inch thickness; thinner cookies taste more delicate, thicker cookies feel a bit sturdier.

Step 4: Cut the heart shapes

Peel off the top sheet of parchment. Use the larger heart-shaped cutter to cut as many hearts as you can from the rolled dough. Transfer the hearts to the prepared baking sheets, leaving a little space between each cookie.

Count how many hearts you cut, then cut out the same number from the second dough disk. Use the smaller heart or round cutter to cut a “window” from the center of half of the hearts. These “window” hearts become the tops, and the solid hearts become the bottoms.

Gather the dough scraps, press them together, chill them briefly if they feel soft, then roll and cut more cookies. Keep the dough cool so the shapes stay clean and don’t spread too much in the oven.

Step 5: Bake the cookies

Preheat your oven to 350°F (175°C) while you finish cutting the cookies. Place one baking sheet in the center of the oven and bake 9–12 minutes, until the edges look just barely golden and the centers look set. The “window” cookies may bake a little faster, so keep an eye on them.

Remove the sheet from the oven and let the cookies sit on the pan for 3–4 minutes. Transfer them to a cooling rack to cool completely. Repeat with the remaining tray of cookies.

Step 6: Dust and fill

Once the cookies cool completely, arrange the tops (the ones with the heart cut-out) on a wire rack or sheet of parchment. Use a fine-mesh sieve to dust them lightly with powdered sugar. This step keeps the sugar off the jam and gives that classic Linzer cookie look.

Spread about 1 teaspoon of raspberry chia jam onto each bottom cookie, leaving a small border around the edge. Gently place a sugared top cookie over each jam-covered bottom and press very lightly so the jam reaches the edges without squishing out. The jam acts like edible glue and holds the sandwich together.

Let the assembled cookies sit for 20–30 minutes so the jam sets slightly and the flavors mingle. The cookies soften a bit over time, which gives that tender, melt-in-your-mouth texture Linzer cookies always promise.

Recipe Variations

Gluten-free version: Use a 1:1 gluten-free baking flour blend in place of all-purpose flour and chill the dough well before rolling.
Vegan version: Use vegan butter sticks, a flax egg (1 tablespoon ground flax + 3 tablespoons water), and maple syrup in the jam.
Low-carb twist: Use a low-carb sweetener that measures like sugar, and swap some of the all-purpose flour with extra almond flour, adding a tablespoon of coconut flour if the dough feels too soft.
Different jam flavors: Use strawberries, blackberries, or a mix of berries in place of raspberries, and adjust the sweetener to taste.
Nut swap: Replace almond flour with ground hazelnuts, pistachios, or pecans for a different flavor profile.
Chocolate version: Spread a thin layer of dark chocolate ganache or dairy-free chocolate spread under the raspberry chia jam.

Ways to Serve Raspberry Chia Jam Heart-Shaped Linzer Cookies Recipe

Serve them with hot tea, coffee, hot chocolate, or a cold glass of milk for an afternoon treat.
Add them to a dessert board with fruit, chocolate squares, and a few other cookies.

Storage Success

Store Raspberry Chia Jam Heart-Shaped Linzer Cookies in an airtight container at room temperature for up to 3 days; they stay tender and the flavors deepen. If your kitchen runs warm, keep them in the refrigerator and bring them to room temperature before serving so the butter in the dough softens again. You can also freeze the unfilled cookies for up to 2 months, then thaw and fill with fresh raspberry chia jam when you need a quick dessert. Keep leftover jam in a jar in the fridge for up to 1 week and spoon it over yogurt, oatmeal, or toast if you somehow run out of cookies first.
