Pumpkin is an essential ingredient from Halloween through Thanksgiving. This a unique pumpkin dessert to share with loved ones this holiday season! Since this mochi cake is so easy to make, you’ll want to make it repeatedly all season along.

Pumpkin butter mochi is a gluten-free alternative to traditional pumpkin pie or pumpkin cake. This recipe highlight’s the versatility of pumpkin!

Classic Hawaiian butter mochi is made with coconut milk and evaporated milk. This version swaps in canned pumpkin puree in place of evaporated milk. The resulting mochi cake is super moist and quite orange!

It’s a bit difficult to categorize butter mochi. Is it a cake, a brownie, or pudding? Well, it’s a mixture of everything! The use of glutinous sweet rice flour creates a soft, chewy, and bouncy cake like texture.

Ingredients

mochiko box, eggs, melted butter, sugar, canned pumpkin puree, and coconut milk can.

You will need: a box of Mochiko, baking powder, sugar, spices, salted butter, canned pumpkin puree, canned coconut milk, and vanilla.

Mochiko is the Koda Farms brand of sweet rice flour. Other brands label the same product as glutinous sweet rice flour. If you opt for a different brand, be sure to use sweet rice flour, not regular rice flour. Sweet rice flour is made from glutinous rice or sticky rice. Its high starch content gives mochi butter cake that iconic chewy texture.

Use your favorite store-bought pumpkin pie spice mix or make your own blend. I don’t like the flavor of ground ginger that is a traditional components of pumpkin spice mix. Instead, I prefer to make a blend of ground cinnamon, ground cloves, and ground nutmeg.

I highly recommend using salted butter for this recipe. It results in an overall tastier mochi cake.

Use full-fat canned unsweetened coconut milk. Check the label to ensure coconut is the first ingredient. Do not use light coconut milk. These lighter coconut milks will not produce the same flavorful results.

Instructions

You simply need a large bowl and a good sturdy whisk to mix together this spiced pumpkin butter mochi cake.

STEP 6: Mochi may rise and puff up during baking. It will settle during cooling. Completely cool pumpkin mochi before slicing.

Serving Suggestions

Cool pumpkin butter mochi for at least an hour before slicing. The cake will be soft while warm, making it difficult to slice clean cuts. The mochi cake can be left in the pan to cool, or unmolded and cooled on a wire rack.

This is best enjoy the same day it is baked! On the first day, the crunchy sugar topping is a nice contrast against the soft and chewy cake portion. Butter mochi is best served at room temperature.

Notes

Baking Vessel (Glass vs Metal): Glass bakeware will result in a firmer, browner crust along the exterior of the cake. However, the interior of the cake will remain soft and chewy.  Metal bakeware is more versatile and can withstand much higher temperatures than glass bakeware. The metal heats up quickly and also cools down faster than glass.
Ingredients:
  • I recommend using Koda Farms Mochiko. Otherwise, look for glutinous sweet rice flour or sweet rice flour. DO NOT USE plain rice flour.
  • Use store-bought pumpkin spice mix or make your own version.  Or, simply use ground cinnamon. I prefer a mixture of cinnamon, nutmeg, and cloves. 
  • Use full-fat canned unsweetened coconut milk. Do not use light coconut milk. It will not produce the same creamy results.
  • Make to to sure pure pumpkin, not “pumpkin pie mix.” 
  • I prefer to make this recipe using salted butter. It makes the overall dessert much tastier. 
Storage:
  • Keep in an covered container at room temperature for up to three days.
  • Freeze leftovers for up to three months. Reheat using a waffle iron to make mochi waffles. Place frozen square in preheated waffle iron. Cook for about 5 minutes, until it stops steaming. Waffle exterior will crisp up as they cool, yet remain chewy on the inside.

    Excellent recipe. Seems too soft at first and while a bit warm, but when it’s really cooled, the texture is perfect.
