What makes these mochi brownies the BEST?
Yo girl has eaten A LOT of brownies and brownie recipes. Almost every month I crave brownies and I sample a new recipe. I am a self-proclaimed brownie connoisseur. And I must say, this butter mochi brownie is truly *chef's kiss. They have that signature crackly top, a beautifully chewy texture, and a rich chocolatey fudgy flavor. Don't believe me? Go try it out yourself!
Are Mochi Brownies gluten-free?
Yes! These butter mochi brownies are a little bit cake and a little bit brownie. This is a delicious gluten-free alternative because it uses glutinous sweet rice flour instead of regular all-purpose flour. The rice flour creates a soft, chewy, and spongy mochi texture that we all love.
Can you make this Butter Mochi Brownie in a different sized pan?
Of course! I used a standard aluminum 8x8 baking pan for the thickness of these butter mochi brownies. You can also use a 9x9 baking pan or a 9x13 baking pan. But please note that using a large pan will result in a shorter thickness! Moreover, the larger pan will also require a shorter baking time.
Ingredients For This Recipe
- Mochiko Rice Flour: can also be called glutinous sweet rice flour. Make sure you use SWEET rice flour and not regular rice flour. It gives the best chewy texture that you want. You can buy Mochiko online here or at your local Asian grocery market in the baking aisle.
- Cocoa powder: for best results use dutch processed cocoa powder. I love using Rodelle's cocoa powder for all my chocolate recipes. You can buy Rodelle's cocoa powder online here.
- Baking Powder: the baking powder acts as the rising agent in this recipe. It allows the mochi to be less dense and have a bit of that airy brownie texture.
- Kosher Salt: the salt balances out all the sugar and chocolate flavors
- Chocolate Chips: you can pick dark, semi-sweet, or milk chocolate chips for your flavor preferences. I recommend buying high-quality melting chocolates. I love using Callebaut melting chocolates.
- Unsalted butter: unsalted butter allows you to control the salt level in your bake.
- Large Eggs: eggs act as a binding and rising agent for the brownies.
- Granulated Sugar: granulated sugar sweetens the recipe.
- Vanilla: the vanilla sweetens the mochi brownies.
- Coffee: the coffee deepens the chocolate flavor without actually coming through. You won't be able to taste the coffee at all. For best results, make sure your coffee is deep, rich, and at room temperature. I used Vietnamese coffee for that bold flavor.
- Whole Milk: You can use other milk alternatives. If you are lactose-free like us, we recommend lactose free milk for that rich milk flavor without the lactose.
- Coconut Milk: Use whole fat canned coconut milk. Do not use reduced-fat coconut milk it is not as thick is more liquidy than full fat. I used Chaokoh Coconut milk in this recipe.
How To Make This Recipe
This recipe is pretty simple and no fancy equipment is needed. All you need are 3 mixing bowls and a whisk and you are ready to go!
- Prepare the oven and the pan. Preheat the oven to 350°F. Line a square 8x8-inch baking pan with parchment paper. Generously butter the parchment paper.
- Whisk the dry ingredients. In a large mixing bowl, whisk together sweet rice flour, cocoa powder, baking powder, and kosher salt.
- Melt the butter and chocolate chips. Using a double boiler, melt the chocolate in a heat-proof bowl over a pot of boiling water until smooth. Stir often to prevent burning. Alternatively, microwave the butter and chocolate chips in a microwave-safe bowl in 30-second increments and stir in between each increment to ensure even melting. Set aside to cool.
- Whisk the remaining wet ingredients + sugar. In a third mixing bowl, whisk together the eggs, sugar, vanilla, room temperature coffee, milk, and coconut milk until thoroughly mixed and the sugar has dissolved.
- Combine the mixtures. Pour the wet ingredient mixture into the dry ingredients and whisk until smooth. Then pour in the chocolate-butter mixture and mix until combined.
- Bake and cool. Pour the mixture into the prepared baking pan. Bake at 350°F in the center of the oven for 50-55 minutes or until a toothpick inserted comes out clean. Cool the mochi brownies on a wire rack in the pan before unmolding.
Tips For This Recipe
- Use a scale! For the best results, use a scale to measure out the ingredients instead of relying on your measuring cups and spoons. This allows for more accuracy.
- Use Koda Farms Mochiko. This is by far the best quality glutinous rice flour out there on the market. For the best chewy texture, go with Mochiko.
- Prepare your pan with parchment paper and butter. This mochi brownie will come out pretty sticky and having a lined and greased cake pan will help you remove the brownie easily.
- For that shiny crinkle top, whisk the sugar with the wet ingredients. Dissolving the sugar in the wet ingredients dissolves the sugar and that is key for the crinkle top.
- Don't be alarmed if the brownies puff up during baking. This is due to the baking powder in the recipe. The brownies will settle and fall once you pull them out of the oven.
Storage Instructions
You can keep these butter mochi brownies in an airtight container in a cool dry place at room temperature for up to 4 days.

Great recipe! Came out so chewy, everyone loved them. I'd recommend using semisweet or milk chocolate chips because I used a mix of semisweet and dark and it came out with a little more dark chocolate bitterness than expected. Also the coffee didn't make a huge differnce but I actually think I liked the batch I made without the coffee better, even though I love coffee 😛 Overall awesome recipe!
