Exquisite and delightful Mooncakes with Lotus Seed Paste and Salted Egg Yolks, perfect for celebrating the Lunar New Year and Mid-Autumn Festival! Full and comprehensive recipe to make mooncakes and their fillings from scratch with step-by-step photos.
For the Mooncake Dough
For the Egg Wash
For the Salted Egg Yolks (see my recipe for Salted Egg Yolks with step-by-step photos)
- This step requires approx. 10 hours or overnight.
- If you are making the Salted Egg Yolks from scratch, start this step at least a day before making the mooncakes.
For the Lotus Seed Paste (see my recipe for Lotus Seed Paste with step-by-step photos)
- This step requires approx. 12 hours or overnight.
- If you are making the Lotus Seed Paste from scratch, start this step at least a day before making the mooncakes.
For the Mooncake Dough (this step requires approx. 45 mins)
- Make the Mooncake Dough on the day you plan to make the mooncakes.
- In a large mixing bowl, whisk together the golden syrup, oil and lye water.
- Add the flour.
- Mix everything together until a dough forms.
- Lightly knead the dough until you have a soft and smooth ball of dough. If the dough is too crumbly and doesn’t come together well, add some water.
- Wrap the dough in some cling film.
- Leave the dough to rest at room temperature for at least 30 minutes.
To Prepare the Mooncake Filling
- For a 50 g mooncake mould, the filling should weigh 30 g (together with the Mooncake Dough of 20 g, the cake will weigh 50 g).
- Use a sharp knife to halve the Salted Egg Yolks.
- Place a plate on a digital kitchen scale. Place a piece of Salted Egg Yolk onto the plate, and add enough Lotus Seed Paste until you have 30 g.
- Roll the Lotus Seed Paste into a ball, flatten it into a round shape, and then fully encase the Salted Egg Yolk. Roll the mixture into a small ball. Repeat with the remaining Salted Egg Yolks and Lotus Seed Paste.
- If you are not using Salted Egg Yolks, simply use 30 g of Lotus Seed Paste for the filling.
- For a 100 g mooncake mould, the filling should weigh 60 g (together with the Mooncake Dough of 40 g, the cake will weigh 100 g). Follow the steps as above, but use a whole Salted Egg Yolk.
To Prepare the Mooncake Dough
- For a 50 g mooncake mould, the Mooncake Dough should weigh 20 g.
- For a 100 g mooncake mould, the Mooncake Dough should weigh 40 g.
- At this stage, the dough should feel slightly oily and sticky.
- Portion the dough as necessary using a digital kitchen scale.
- Roll each piece of dough into a smooth ball.
To Assemble the Mooncakes
- Line a large baking tray with baking paper.
- Flatten a piece of Mooncake Dough into a thin round shape which is just large enough to encase the filling.
- Bring the edges of the dough up around the filling, cupping the mixture between your thumb and forefinger as you do so.
- Gently pinch the dough until it stretches to completely cover the filling.
- Pinch any cracks together, or even add a bit of extra dough to patch up any cracks if necessary.
- Roll the mixture into a smooth ball.
- Place the balls of filled dough onto the lined baking tray.
To Shape the Mooncakes
- Prepare the mooncake moulds by affixing your desired stamp to the plunger.
- It may be wise to lightly dust the moulds with some flour to stop the cakes from sticking to the stamps. But I generally find that the dough does not stick, especially if you are using the plastic mooncake moulds like I have.
- Place one ball into the mould. For square moulds, I recommend gently pushing the ball of dough into a squarish-shape with your fingers before inserting it into the mould.
- Place the plunger directly onto the baking tray, and press the plunger down with some gentle pressure. If you press down too hard, you might flatten the cakes too much.
- Gently release the mould from the cake.
- Repeat with the remaining balls of filled dough.
- The cakes do not spread as they bake, but I would still recommend spacing them apart so that they bake evenly.
To Bake the Mooncakes
- Preheat the oven to 180°C/356°F (without fan).
- Bake the mooncakes for 10 minutes.
- Remove the baking tray from the oven and let the cakes cool for 10 minutes.
- Reduce the oven temperature to 160°F/320°F (without fan).
- Meanwhile, make the Egg Wash by whisking the egg with some water in a small bowl.
- Lightly brush the mooncakes with the Egg Wash, using a pastry brush with fine bristles (a silicon brush picks up too much egg wash for this task). Try to avoid putting too much Egg Wash onto the intricate patterns on the surface. If you have too much Egg Wash on the cakes, use some kitchen paper to blot the cakes.
- Return the baking tray to the oven.
- Continue baking the mooncakes for 10-15 minutes, or until they are golden brown all over.
- Let the mooncakes cool completely on the baking tray, which will allow them to develop a crisp bottom.
To Store the Mooncakes
- Store the mooncakes in an air-tight container at room temperature for up to 1 week.
- The mooncakes are typically served after 1-2 days when the dough has softened slightly and the patterns become more settled and defined. However, I recommend trying at least one while it is still fresh and the dough is somewhat crispy.
- The mooncakes can also be stored in an air-tight container in the fridge. Bring the cakes to room temperature before serving.
