This recipe is my go-to for gatherings, afternoon tea, and those afternoons when I want something nostalgic but completely plant-based. I first developed this version of jam tarts during a weekend when I had a surplus of raspberries from a local farmers' market and a craving for something buttery and sweet. The result is a tender shortcrust that manages to be both crumbly and slightly crisp, paired with a quick, bright raspberry filling that highlights fresh fruit without overpowering it. Every time I bake a batch, the house fills with the scent of baked fruit and warm pastry, and people line up for seconds.

What makes these particularly special is how few ingredients they require and how adaptable they are: you can make the jam in a small saucepan in under 15 minutes, or use a good-quality store jam if you prefer to skip that step. The pastry relies on a vegan block-style spread for a rich mouthfeel — or, if you need an oil-based option, there's a clear swap that still yields excellent results. These tarts travel well, store beautifully, and are an easy dessert to scale up when company arrives.

Ingredients

• Quick Raspberry Jam: 1 cup fresh or frozen raspberries, chopped — choose ripe but firm berries for bright flavor; frozen works well when fresh aren’t available.
• Sugar: 1/2 cup granulated sugar — use regular granulated or caster sugar; adjust sweetness to taste if your berries are very sweet.
• Water: 1/4 cup water — just enough to help the fruit break down; add a splash more if needed to reach jam consistency.
• Cornstarch: 2 tablespoons cornstarch — acts as a thickener; swap for 2 teaspoons white chia seeds to make a chia jam alternative (no extra water needed).
• Flour: 1 3/4 cups all-purpose flour, plus extra for dusting — plain flour gives the right structure and a tender crumb.
• Vegan butter: 1/2 cup plus 1 tablespoon vegan block-style spread (approx. 125 g) at room temperature — a block spread gives the best shortcrust texture; brands with a higher fat content make the pastry more tender.
• Icing sugar: 1/3 cup powdered sugar — helps the dough bind and keeps the texture soft; sift to avoid lumps.
• Cold water: 3 tablespoons cold water, add more in teaspoons if dough is dry — helps bring the dough together without overworking it.
• Optional salt: pinch of fine salt — especially useful if using a neutral oil or unsalted alternatives to enhance the buttery flavor.

Instructions

Make the raspberry jam: Place the raspberries, sugar, water and cornstarch into a small saucepan and whisk until smooth with no visible lumps of cornstarch. Over medium heat, mash the fruit with the back of a fork or a stick blender and bring to a gentle simmer. Stir continuously for 5–10 minutes until the mixture thickens to a jam-like consistency. If it looks too thin, simmer a little longer; if it becomes too thick, add a teaspoon or two of water to loosen. Remove from heat and let cool — it will set further as it cools. Combine the pastry ingredients: In a large bowl or food processor, add the flour and powdered sugar and pulse briefly to combine. Rub in or pulse the vegan block spread until the mixture resembles coarse crumbs. Add the cold water, one tablespoon at a time, and bring the dough together just until it forms a soft, pliable ball. The dough should be soft enough to pinch without cracking but not sticky. If needed, add a tablespoon more water or a tablespoon more flour to reach the right texture. Avoid overworking. Shape and chill (optional): On a lightly floured surface, press the dough into a smooth disc, cover with plastic or a bowl and chill for 15–30 minutes if you have time — chilling helps relax the gluten and makes rolling easier. If short on time, you can roll immediately; just handle gently. Cut and assemble: Preheat the oven to 350°F (180°C). Grease around 20 mini shallow tart tins. Roll the dough to about 1/4 inch thickness and cut 2 1/2-inch circles using a fluted cutter. Gently press each circle into the tart moulds, pressing to the edges and bottom. Spoon about 1 tablespoon of cooled jam into the centre of each pastry shell, smoothing gently to level. Bake and cool: Bake for approximately 18–22 minutes, or until the pastry is lightly golden at the edges. Remove from the oven and place the pans on a wire rack to cool completely — the pastry firms up as it cools and the jam sets. Once cool, carefully remove tarts from the tins.

Storage Tips

Store these tarts in a single layer in an airtight container to preserve the delicate edges. At room temperature they remain crisp and enjoyable for up to two days; after that the jam may begin to weep slightly. For longer storage, refrigerate for up to a week — allow chilled tarts to come to room temperature for 20–30 minutes before serving to restore tenderness. To freeze, flash-freeze on a tray until firm, then layer between sheets of parchment in a freezer container; reheat briefly in a low oven (300°F / 150°C for 8–10 minutes) to revive crispness.

Ingredient Substitutions

If you prefer not to use a block-style vegan spread, you can use spreadable margarine or coconut oil. For spreadable margarine, omit the extra added water and increase flour slightly if the dough seems soft; for coconut oil, use the same quantity but expect a slightly different texture and a hint of coconut flavor — add a pinch of salt to mimic buttery notes. To make the jam without cornstarch, replace it with 2 teaspoons of white chia seeds and omit the water; the jam will thicken as the chia hydrates and produces a slightly seedy texture.

Serving Suggestions

These mini tarts are delightful on a dessert spread alongside shortbread and fruit slices. For afternoon tea, dust with a light sprinkle of powdered sugar and serve with plant-based cream or a dollop of coconut yogurt. They also pair wonderfully with chamomile or Earl Grey tea, and make a charming addition to picnic boxes — pack them flat to prevent crushing. Garnish ideas include a small fresh raspberry, a tiny mint leaf, or a thin lemon zest curl for brightness.

Cultural Background

Jam tarts have a long heritage in British baking, where simple combinations of pastry and fruit were valued for both their flavor and economy. Mini versions became popular as finger-food desserts for tea and social gatherings. This vegan adaptation keeps the traditional shape and balance while swapping in plant-based fats — a modern update that honors the classic texture and appearance. In Australian baking culture, jam tarts are equally popular and often appear in school bake sales and home afternoon snacks.

Seasonal Adaptations

Switch the filling with seasonal fruit: use strawberry or apricot in summer, spiced apple in autumn (cook apples with a touch of cinnamon), or a cranberry-orange conserve for winter holidays. In warmer months, fold a little lemon zest into the jam for extra brightness. For holiday tarts, brush the tops with a thin glaze of warmed jam and sprinkle with finely chopped toasted almonds or coconut for a festive finish.

Meal Prep Tips

For efficient meal prep, make the jam and dough a day ahead. Store the jam chilled in a sealed jar and the dough wrapped in the fridge. On the day you bake, roll and cut the shells and fill just before baking for the freshest texture. Alternatively, press the dough into tart pans and freeze unbaked shells for up to one month; fill from frozen and bake a few minutes longer until golden.

These tarts are small, unfussy, and full of nostalgia — a simple pleasure worth sharing. Try a batch this weekend and adapt the filling to whatever fruit is most abundant where you live; I guarantee they'll disappear fast.
