Pumpkin Spice Mochi
Whenever autumn rolls around, my thoughts turn to all things pumpkin spice, and this Pumpkin Spice Mochi Cake is a new favourite in our home. What is delicious about a baked mochi cake is the crispy topping and edges which contrasts beautifully against the soft and chewy cake slice. My son and I compete against each other for the edges and, as mochi cake loses any crispness the next day, it is one of the rare times when I let my family eat a cake from the outer edges inwards.
But even if it is not autumn and you have access to canned pumpkin, this mochi cake is a relatively quick and simple dessert, perfect for pot-luck parties or a delicious dessert after an Asian meal.
What is Pumpkin Spice Mochi Cake?
This Pumpkin Spice Mochi Cake is similar to a Hawaiian-style Butter Mochi Cake, but with the autumnal addition of pumpkin purée, cinnamon and nutmeg. It has the soft and chewy texture of a traditional mochi, but with the cosy flavours of pumpkin spice which we all love.

Pumpkin Spice Mochi Recipe
Traditional mochi is made by steaming the cake batter, before shaping it into balls or encasing it around different kinds of fillings.
A Hawaiian-style Butter Mochi Cake, on the other hand, is a baked cake, and which happens to be a lot easier to make because you don’t have to handle any sticky dough, nor shape any little cakes.
I have altered my Butter Mochi Cake recipe and transformed it into this autumnal treat by simply including some pumpkin purée and additional spices. I have actually been light-handed with the spices, so if you prefer a more robustly spiced cake, I recommend adding more cinnamon and freshly grated nutmeg.
This dessert does not taste overly of pumpkin; like most pumpkin desserts, the pumpkin mostly adds sweetness, as well as colour.

What is Glutinous Rice Flour?
Glutinous rice flour is milled from sweet rice grains, hence it is sometimes labelled as sweet rice flour. However, glutinous rice flour is not sweet in flavour.
Also, contrary to the use of “glutinous” in its name, glutinous rice flour does not contain gluten. Glutinous rice flour is gluten-free. This means that Butter Mochi Cake is gluten-free.
The term “glutinous” refers to the thick and sticky consistency of the rice flour when it is cooked.
When buying glutinous rice flour from an Asian grocery store, be careful that you are not buying rice flour. Both products look the same but, when cooked, they behave very differently.
Most Asian grocers will stock glutinous rice flour and rice flour side-by-side. One trick which seems to work for most Asian brands is that glutinous rice flour has green packaging, whereas rice flour has red packaging.

How to Make Pumpkin Spice Mochi Cake
Step 1
Whisk the eggs and sugar until the mixture is light and pale.

Step 2
Add the melted butter, coconut milk, vanilla, and pumpkin purée. Whisk to combine.

Step 3
Add the glutinous rice flour, salt, ground cinnamon, ground ginger, and nutmeg.

Step 4
Whisk until you have a thick and smooth batter.

Step 5
Generously grease a round baking dish measuring 24 cm/9.5 inches with some butter. For this recipe, I like to use a ceramic dish which will look nice for serving.
Pour the batter into the dish, and use an off-set spatula to evenly spread the batter. Tap the dish a few times on the bench top to remove any air bubbles.

Step 6
Bake for about 40-55 minutes, or until the cake is lightly golden all over and the centre feels firm when lightly touched. The cake will rise and crack a little upon baking, but it will settle as it cools.
Let the cake cool in the baking dish for at least 30 minutes before slicing and serving.



Pumpkin Spice Mochi Cake
Ingredients
- 1 teaspoon unsalted butter, for greasing
- 2 eggs
- 220 g (1 cup) caster sugar, (superfine sugar)
- 25 g (1 ½ tablespoons) unsalted butter, melted and cooled
- 400 ml (1 ½ cup plus 1 tablespoon) coconut milk
- 1 teaspoon vanilla extract
- 100 g (⅓ cup) pumpkin purée, fresh or canned
- 225 g (8 oz) glutinous rice flour, also called sweet rice flour or Mochiko flour
- 3 g (½ teaspoon) fine salt
- 1 teaspoon ground cinnamon
- ½ teaspoon ground ginger
- ¼ teaspoon nutmeg, freshly grated, or more to taste
Instructions
- Preheat the oven to 180°C/350°F (without fan).
- Generously grease a round baking dish measuring 24 cm/9.5 inches.
- In a large mixing bowl, whisk together the eggs and sugar until the mixture is a pale yellow.
- Add the melted butter, coconut milk, vanilla extract, and pumpkin purée.
- Whisk to combine.
- Slowly whisk in the glutinous rice flour, salt, cinnamon, ginger, and nutmeg.
- Keep whisking until you have a thick and smooth batter. You don’t have to worry about over-mixing because this batter does not contain any gluten.
- Pour the batter into the greased baking dish.
- Tap the baking dish on the bench top a few times to bring any air bubbles to the surface.
- Bake the cake for about 40-55 minutes, or until the cake is lightly golden all over and the centre feels firm when lightly touched. The cake should puff up slightly during baking, which will indicate that it is cooked all the way through. Upon cooling, the cake will settle a little.
- Place the baking dish on a wire rack and allow the cake to cool (in the baking dish) for at least 30 minutes.
- Use a sharp knife to slice the cake and serve immediately.
- This mochi cake tastes best on the day it is baked because the topping and the edges will be nice and crispy. Any leftovers can be kept in the fridge and reheated (see below), but it will lose its crispness.
Kitchen Notes
- DOUBLE THE RECIPE
You can double this recipe to make a bigger serving for large gatherings. I recommend using a baking dish measuring approximately 30 x 40 cm/12 x 16 inches. Bake for 60-75 minutes, or until lightly golden all over and cooked in the centre. - MAKE IT DAIRY-FREE
Substitute the butter for margarine or another plant-based alternative to make the cake dairy-free. - STORING LEFTOVER MOCHI CAKE
Leftovers can be kept in the fridge for several days, or individually wrapped in the freezer. I like to freeze two slices at a time in a vacuum-sealed bag or ziplock freezer bag. - REHEATING LEFTOVER MOCHI CAKE
Leftover mochi cake tastes best when it is reheated. Reheat them in the microwave until they are just warmed through (about 15-20 seconds). - HOMEMADE PUMPKIN PURÉE
* Peel and remove the seeds from about 500 g (1 lb) of pumpkin.
* Cut the pumpkin into large pieces of roughly equal size.
* To boil, bring a large pot of water to the boil, add the pumpkin and cook for about 30 minutes until the pumpkin is tender.
* To steam, bring a large pot of water to the boil, place the pumpkin in the steamer basket and steam for about 50-60 minutes, or until the pumpkin is tender (the timing will depend on how large the pumpkin pieces are).
* Place the cooked pumpkin into the bowl of a large food processor and blitz until you have a fine purée.
* Leave the purée to cool completely before using in this recipe.
* Any leftover pumpkin purée can be kept in a covered container in the fridge for a few days. - OVEN & STOVE TEMPERATURES
