Step‑by‑Step Instructions for Butter Mochi
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures that the oven reaches the ideal temperature when you’re ready to bake your butter mochi, resulting in a perfectly set cake. While the oven heats, gather your ingredients and prepare your baking pan.
Step 2: Prepare the Baking Pan
Grease a 9 x 13-inch baking pan with a little butter or non-stick spray. Then, line the bottom with parchment paper for easy removal later. This preparation will help create a smooth surface when you slice your butter mochi and ensures it won’t stick to the pan.
Step 3: Mix the Butter and Sugar
In a large mixing bowl, combine the melted unsalted butter and granulated sugar. Using a whisk or electric mixer, blend them together until the mixture is thoroughly combined and appears smooth and glossy. This step lays the foundation for the rich flavor and texture of your butter mochi.
Step 4: Incorporate the Wet Ingredients
Next, add the evaporated milk, coconut milk, vanilla extract, and large eggs to the butter and sugar mixture. Mix everything together until fully combined, ensuring a creamy consistency without any lumps. This step enhances the tropical flavor profile of your butter mochi.
Step 5: Add the Dry Ingredients
Gradually fold in the glutinous rice flour and baking powder. Use a spatula to gently mix on low speed or by hand until the batter is smooth and everything is well incorporated. Avoid over-mixing, as this can affect the cake’s chewy texture, a key characteristic of butter mochi.
Step 6: Bake the Butter Mochi
Pour the prepared batter into your greased and lined baking pan, spreading it evenly. Place it in the preheated oven and bake for about 60 minutes. You’ll know it’s ready when a toothpick inserted in the center comes out clean, with a slightly golden top.
Step 7: Cool and Serve
Once baked, remove the butter mochi from the oven and let it cool in the pan for at least 15 minutes before transferring it to a wire rack. Allow it to cool completely before slicing it into squares. This cooling period is essential for achieving the perfect chewy texture in every bite.

Expert Tips for Butter Mochi
- Premeasure Ingredients: Gather and measure all ingredients beforehand to ensure a smooth baking process, keeping your butter mochi consistent every time.
- Avoid Over-Mixing: Gently fold the flour into the batter; over-mixing can lead to a denser texture, which is not the goal for this chewy delight.
- Cooling Time Matters: Allow the butter mochi to cool completely before slicing. This step is crucial to achieve that wonderfully chewy consistency.
- Check Bake Time: Ovens may vary, so check for doneness a few minutes early; a toothpick should come out clean, not wet.
- Storing for Freshness: Keep the leftovers in an airtight container at room temperature. Refrigeration can change the delightful chewy texture of your butter mochi.
Storage Tips for Butter Mochi
Room Temperature: Store your butter mochi in an airtight container at room temperature for up to 2 days to maintain its chewy texture and delicious flavor.
Fridge: If you want to extend its freshness, refrigerate for up to 5 days. However, avoid chilling if you prefer to keep that delightful chewiness.
Freezer: For longer storage, wrap slices in plastic wrap and place them in an airtight container. Butter mochi can be frozen for up to 3 months.
Reheating: To enjoy this tropical delight after freezing, simply thaw in the fridge overnight and warm in the microwave for about 10-15 seconds before serving.
Make Ahead Options
These Butter Mochi squares are perfect for meal prep enthusiasts looking to save time during busy weeknights! You can prepare the batter up to 24 hours in advance by mixing all the ingredients (just remember to refrigerate it to maintain freshness). The unique chewy texture of the butter mochi can be preserved by ensuring it’s tightly covered to prevent it from drying out. When you’re ready to bake, simply pour the batter into your greased pan and follow the baking instructions as usual. This method allows you to enjoy a delightful Hawaiian treat without much fuss, giving you restaurant-quality results with minimal effort!

Butter Mochi Recipe FAQs
How do I select the right ripeness of ingredients for Butter Mochi?
Absolutely! Ensure your eggs are fresh and at room temperature for optimal mixing. For the best flavor, use high-quality coconut milk or cream, which should be rich and without dark spots. If you’re using evaporated milk, check the expiration date to ensure freshness, as old dairy can negatively impact your cake.
What’s the best way to store Butter Mochi?
To keep your Butter Mochi fresh, store it in an airtight container at room temperature for up to 2 days. If you want it to last longer, refrigerate it for up to 5 days, but be aware that chilling may make it less chewy, as the texture could change slightly.
Can I freeze Butter Mochi, and if so, how?
Yes, you can! To freeze Butter Mochi, first allow it to cool completely. Then, slice the cake into squares and individually wrap each piece in plastic wrap. Place these wrapped portions in an airtight container or freezer-safe bag and freeze for up to 3 months. When you’re ready to enjoy, thaw in the fridge overnight and warm in the microwave for 10-15 seconds before serving to regain that delightful chew.
What if my Butter Mochi doesn’t rise properly?
If your Butter Mochi doesn’t rise as expected, there are a couple of things to check. Ensure your baking powder is fresh; an old leavening agent may lose its potency. Also, be cautious not to over-mix the batter after adding glutinous rice flour, as this can lead to a denser texture. Quick checks with a toothpick inserted into the center of the cake will help ensure it rises appropriately and is baked through.
Is Butter Mochi suitable for people with allergies?
While Butter Mochi is gluten-free, it does contain eggs and dairy. For those with egg allergies, I recommend using a flaxseed egg (1 tablespoon ground flaxseed mixed with 2.5 tablespoons of water, let sit for a few minutes to thicken) as a replacement. For a dairy-free version, use non-dairy milk alternatives, such as almond or oat milk, and ensure your butter is substituted with a plant-based version. Always double-check ingredient labels if sharing with others who have allergies.
