Japanese steam cake, or mushi pan, is a delightful treat that is light, fluffy, and subtly sweet. This cake is steamed rather than baked, giving it a unique texture that is both moist and airy. Perfect for a quick snack or a light dessert, mushi pan is easy to make and requires just a few simple ingredients.
Most of the ingredients for this recipe are common pantry staples. However, if you don't have vanilla extract at home, you might need to pick some up at the supermarket. It's a key ingredient that adds a lovely aroma and flavor to the steam cake.

Ingredients for Japanese Steam Cake (Mushi Pan)
All-purpose flour: The base of the cake, providing structure and texture.
Baking powder: A leavening agent that helps the cake rise and become fluffy.
Sugar: Adds sweetness to the cake.
Egg: Binds the ingredients together and adds richness.
Milk: Adds moisture and helps create a tender crumb.
Vegetable oil: Adds moisture and helps keep the cake soft.
Vanilla extract: Adds a pleasant aroma and enhances the flavor of the cake.
Technique Tip for Making Mushi Pan
When mixing the wet ingredients with the dry ingredients, be careful not to overmix the batter. Overmixing can lead to a dense and tough texture in your steam cake. Aim for a smooth consistency, but stop mixing as soon as the ingredients are just combined. This will help ensure your Mushi Pan remains light and fluffy.

Alternative Ingredients
all-purpose flour - Substitute with cake flour: Cake flour has a lower protein content, resulting in a lighter and more tender texture, which is ideal for Japanese steam cake.
all-purpose flour - Substitute with gluten-free flour blend: For those with gluten intolerance, a gluten-free flour blend can be used to achieve a similar texture.
baking powder - Substitute with baking soda and cream of tartar: Use ¼ teaspoon baking soda and ½ teaspoon cream of tartar to replace 1 teaspoon baking powder, as they create the same leavening effect.
sugar - Substitute with honey: Honey adds a natural sweetness and moisture, but reduce the milk slightly to balance the extra liquid.
sugar - Substitute with maple syrup: Maple syrup provides a unique flavor and sweetness, but again, reduce the milk slightly to account for the extra liquid.
egg - Substitute with flaxseed meal and water: Mix 1 tablespoon flaxseed meal with 3 tablespoon water to replace one egg, providing a similar binding effect for a vegan option.
egg - Substitute with applesauce: Use ¼ cup applesauce to replace one egg, adding moisture and a slight sweetness, suitable for a vegan alternative.
milk - Substitute with almond milk: Almond milk is a dairy-free alternative that provides a similar consistency and mild flavor.
milk - Substitute with coconut milk: Coconut milk adds a rich, creamy texture and a subtle coconut flavor, suitable for a dairy-free option.

How To Store or Freeze Mushi Pan
- Allow the Japanese steam cakes to cool completely at room temperature before storing. This prevents condensation from forming, which can make the cakes soggy.
- Place the cooled mushi pan in an airtight container. If stacking them, separate each layer with parchment paper to prevent sticking.
- Store the container in a cool, dry place if you plan to consume the cakes within 1-2 days. For longer storage, refrigerate them. They can last up to a week in the refrigerator.
- For freezing, individually wrap each steam cake in plastic wrap to protect them from freezer burn. Then, place the wrapped cakes in a resealable freezer bag or an airtight container.
- Label the container with the date of freezing to keep track of freshness. The mushi pan can be frozen for up to 2 months.
- To thaw, remove the desired number of cakes from the freezer and let them sit at room temperature for about 1-2 hours. Alternatively, you can microwave them on a low setting for a few seconds until they are soft and warm.
- For a freshly steamed texture, reheat the thawed steam cakes in a steamer for 3-5 minutes. This will help restore their original softness and moisture.
- Enjoy your Japanese steam cakes as a delightful snack or dessert, pairing them with a cup of green tea or your favorite beverage.
