Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

• All‑purpose flour

• Unsalted butter, chilled and cubed

• Granulated sugar

• Egg yolk

• Vanilla extract

• Dark chocolate (at least 70% cocoa), chopped

• Heavy cream

• Cornstarch

• Gel food colouring: midnight blue, violet, and black

• Edible lustre dust or shimmer powder (silver or iridescent)

• Edible stars or silver dragees

Directions

1. Prepare the tart shells:

   • Preheat your oven to 180 °C (350 °F).

   • Combine flour, chilled butter, and sugar in a mixing bowl. Pulse or rub together until the mixture resembles coarse crumbs.

   • Add egg yolk and vanilla extract, mixing until the dough just comes together. Do not overwork.

   • Press the dough into tart pans, lining the bottom evenly. Prick with a fork. Chill in the refrigerator for 30 minutes.

2. Bake the tart shells:

   • Line the chilled tart shells with parchment paper and fill with pie weights or dried beans.

   • Bake for 15 minutes, then remove weights and parchment. Bake for an additional 10‑12 minutes or until golden.

   • Allow to cool completely.

3. Make the chocolate ganache filling:

   • Heat the heavy cream gently until it just begins to simmer.

   • Pour over chopped dark chocolate, let sit for 2 minutes, then stir until smooth and glossy.

   • If a thicker texture is desired, dissolve cornstarch in a little cold cream and stir into the ganache while gently reheating until it thickens slightly.

4. Create the galaxy effect:

   • Divide the ganache into three portions. Tint one portion with midnight blue, another with violet, and the last portion remains chocolate dark (or black‑tinted).

   • Spoon or pipe small amounts of each colour into the cooled tart shells, alternating to create swirling patterns. Use a toothpick or skewer to drag through colours to form stars and galaxies.

5. Add shimmer and decorations:

   • Dust the surface lightly with edible lustre or shimmer dust for a celestial glow.

   • Place edible stars or silver dragees sparingly to mimic stars.

6. Set the tarts:

   • Chill the tarts in the refrigerator for at least 2 hours or until the ganache is firmly set before serving.

Servings and Timing

• Servings: Makes approximately 6 standard tartlets (about 8 cm / 3‑inch diameter each) or 1 large tart (about 22‑24 cm / 9‑10‑inch).

• Preparation time: ~ 30 minutes for dough and setting up tart shells + about 20 minutes to prepare ganache and decorate.

• Baking time: ~25‑30 minutes.

• Chilling/setting time: Minimum 2 hours.

• Total time: Approximately 3 hours (including chilling time).

Variations

• White chocolate galaxy: Use white chocolate for the ganache, and tint with pastel blues, pinks, and purples for a softer galaxy aesthetic.

• Fruit‑filled centre: Add a thin layer of berry compote (such as blueberry or blackberry) at the bottom of the tart before adding the ganache swirl for added flavour.

• Vegan or dairy‑free option: Substitute butter with plant‑based margarine, use coconut cream instead of heavy cream, and choose dairy‑free chocolate.

• Mini bites: Use mini muffin tins to create bite‑sized tarts for parties or events.

Storage/Reheating

• Storage: Store the galaxy tarts in the refrigerator, covered with plastic wrap or in an airtight container, for up to 4 days.

• Freezing: You may freeze unfilled tart shells for up to 1 month. For filled tarts, freezing is not recommended as decoration may degrade and texture may suffer.

• Reheating / Serving: Remove from fridge about 10‑15 minutes before serving to allow flavours to soften. Do not heat in oven or microwave — the shimmer decorations may melt or lose appearance.

FAQs

What kind of chocolate works best for the ganache?

Dark chocolate with at least 70 % cocoa gives richness and depth. If you prefer milder flavour, a 55‑65 % chocolate or even white chocolate can be used with appropriate adjustments in sweetness.

Can I make the tart shells ahead of time?

Yes, you can bake the tart shells a day in advance. Store them in an airtight container at room temperature. Fill the next day for best texture.

How do I prevent the crust from shrinking during baking?

Chill the dough thoroughly before baking. Also, ensure you press the dough firmly into the sides and bottom of the pan, and use pie weights (or dried beans) during the first bake to prevent puffing or shrinking.

What if the ganache is too runny?

If it is too runny, warm it gently and whisk in a small amount of cornstarch dissolved in cold cream, or allow it to cool and thicken on its own in the refrigerator.

Can I use gel colourings, or should I use liquid food colouring?

Gel colourings are preferable for vibrant, intense colours without altering the consistency. Liquid colourings can work but may thin the ganache if used in excess.

How do I get the swirling galaxy design just right?

Spoon or pipe your different coloured ganaches in alternating spots, then drag a toothpick or skewer through the colours in gentle curves. Work quickly before ganache sets.

Will the shimmer dust affect taste?

Edible lustre or shimmer dust is typically flavourless, so it does not alter taste but does add visual sparkle. Ensure it is labelled as food‑safe.

How do I store these tarts if I’m transporting them?

Place them in a rigid container to protect the decoration, keep cool (using ice packs if needed), and avoid stacking. Chill thoroughly before transport.

Can I adapt this recipe for gluten‑free?

Yes. Substitute the all‑purpose flour with a gluten‑free flour blend that contains a binder (such as xanthan gum). Be mindful that texture may be slightly more crumbly.

What if I want to make vegan shimmer galaxy tarts?

Use dairy‑free alternatives: plant‑based butter, coconut cream, and vegan chocolate. Make sure all decorative elements (lustre dust, stars) are certified vegan.
