These matcha mochi brownies are cakey, yet dense, moist, and chewy! They’re full of deep, earthy matcha flavor, which is perfectly balanced out by the sweetness of my homemade microwave matcha ganache.

What Are Mochi Brownies?

Mochi brownies are pretty comparable to traditional brownies—both use similar ingredients and can be fudgy, dense, or cakey, depending on the specific recipe. However, despite whether they’re fudgy or cakey, mochi brownies also have an added chewy, bouncy texture to them, just like Japanese mochi!

This is because instead of using all-purpose flour like conventional brownies, mochi brownies use sweet glutinous rice flour, aka mochiko. A higher amount of liquid in the batter yields much chewier, squishier, mochi-like bars, similar to butter mochi. Less liquid yields much more cake-like brownies.

And since I was going for cakey and dense brownies, I had to play around with the ingredients. After testing this recipe about 8 times (omg), I found the perfect ratio.

So, if you’re looking for deliciously cakey, yet chewy mochi brownies, I highly recommend this recipe!

Ingredients

For the matcha mochi brownies:

Instead of all-purpose flour like conventional brownies, we’ll be using mochiko. This creates the signature chewy, bouncy texture we’re looking for!
The unsalted butter, milk, and vanilla adds moisture and a rich flavor to the brownies. The granulated sugar provides sweetness, which enhances the earthiness of the culinary matcha powder.
Eggs bind the ingredients together and also helps the brownies rise a bit in the oven.
I like to use table salt because it is more readily available in home kitchens.

For the matcha ganache:

💡 Baking Tip

Weigh your ingredients! One of my favorite kitchen tools is a kitchen scale because it’s more accurate than measuring by volume. If you use cups, spoon the flour in gently, then level it with a knife or spatula.

Matcha Mochi Brownies FAQs

Can I use regular rice flour for mochi brownies?

No, regular rice flour will not work for this recipe.

Rice flour is completely different than sweet glutinous rice flour, aka mochiko. They are from different grains of rice and yield very different textures when baked.

Why use culinary grade matcha instead of ceremonial?

I like to use culinary grade in all of my matcha baking, since ceremonial matcha is more expensive and best enjoyed as a simple tea.

Storage

Room Temperature: The mochi brownies can be stored in an airtight container at room temperature for up to 3 days.
Freezing Instructions: Freeze fully cooled mochi brownies in an freezer-safe container for up to 3 months. I recommend letting them thaw at room temperature for 15-20 minutes before eating.
