Must-Have Components

  • Mochiko Sweet Rice Flour: 16 oz/454g box, crucial for authentic mochi chew
  • Butter: 1 cup/226g unsalted, melted, forms crunchy borders
  • Sugar: 2 cups/400g granulated, delivers proper sweetness
  • Milk: 1 cup/240ml whole, contributes smooth richness
  • Eggs: 4 large, room temperature, holds everything together
  • Coconut Milk: 13.5 oz/400ml can unsweetened, adds island zing
  • Baking Powder: 2 teaspoons, creates slight rise
  • Vanilla Extract: 1 tablespoon pure, boosts taste profile
  • Salt: 1 teaspoon kosher, cuts through sweetness
  • Coconut: 1 cup/85g unsweetened shredded, builds distinctive topping
  • Sea Salt: 1/2 teaspoon flaky (optional), finishing touch

In my family, the corner bits always get snatched up first since they've got those extra chewy edges plus the soft middle. I've started cutting those pieces bigger to avoid arguments.

Oven Watch

Look for golden brown color with slight movement in the middle. When you gently shake the pan, it should wiggle a bit which shows it's perfectly done.

Rest Time

Cool fully on a wire rack for one hour before slicing. This waiting period lets the texture fully set and helps you get clean cuts.

Setup Advice

Get all ingredients ready and laid out before you start. This neat approach makes the whole process run smoothly from beginning to end.

Serving Ideas

Slice into big squares when serving. While they're fantastic on their own, fresh tropical fruits make a wonderful side addition.

Twist Options

Try adding a splash of almond or coconut extract for different flavor notes while keeping the classic stretchy mochi feel.

Keeping Fresh

Keep in an airtight box at room temp for up to three days. The texture changes but stays wonderfully chewy throughout.

Frequently Asked Questions

→ What’s mochiko flour, and where can I get it?
Mochiko is a type of sticky rice flour, often called sweet rice flour. Try looking in Asian grocery stores or the international aisle of your supermarket.
→ Why is cutting mochi easier with a plastic knife?
Since mochi sticks a lot, using a plastic knife gives you smooth cuts without it clinging to the blade.
→ How do I make this dairy-free?
Use coconut oil instead of butter and extra coconut milk instead of regular milk for a delicious dairy-free version.
→ How can I keep butter mochi from drying out?
Put it in an airtight container. It’ll stay good for three days on your counter or up to a week in the fridge.
→ Why are there cracks on my mochi's surface?
Small cracks are fine and don’t change the taste. To avoid them, ensure your oven’s set at the right temp, and let the dessert cool slowly after baking.

Ingredients

→ Base Ingredients

01 2 teaspoons baking powder
02 2 cups granulated sugar
03 1/2 teaspoon sea salt
04 1 pound mochiko (sweet rice flour)

→ Wet Ingredients

05 4 large eggs
06 2 cups of any milk you like
07 A 13.5-ounce can of unsweetened coconut milk
08 2 teaspoons vanilla extract
09 1 stick of butter (8 tablespoons), melted, and a bit extra for greasing

→ Topping

10 1/2 cup unsweetened shredded coconut
11 Optional: flaky salt if you’re into it

Instructions

Step 01

Set your oven to 350°F and place an oven rack in the middle position. Use some butter or oil to grease a 9x13-inch baking pan. While you're doing this, go ahead and melt your stick of butter.

Step 02

Grab a big bowl. Add in the mochiko, sugar, salt, and baking powder. Whisk them together until everything looks evenly mixed.

Step 03

In a smaller bowl, beat the eggs, milk, and vanilla together until smooth.

Step 04

Take the wet mix and slowly stir it into the dry bowl using a wooden spoon. Once blended, pour the melted butter and coconut milk in. Keep stirring until there are no lumps left.

Step 05

Pour the finished batter into your greased baking dish. Gently tap the pan on the counter to smooth it out and remove any trapped air bubbles.

Step 06

Sprinkle the shredded coconut evenly across the top. If flaky salt sounds good to you, add a light sprinkle, but don’t go overboard or mess up the smoothed batter.

Step 07

Slide the pan into your preheated oven. Bake it for about an hour to 70 minutes, or until the top looks golden and the cake feels firm.

Step 08

Once out of the oven, place the pan on a cooling rack. Leave it for about an hour to fully cool. To cut, use a greased plastic knife to get clean edges, and slice into 20 neat rectangles.

Notes

  1. Use a plastic knife to slice the cooled dessert cleanly.
  2. Stores might label sweet rice flour as 'mochiko' flour.
  3. If your knife sticks, butter or oil it a little.
