Ingredients
- Nonstick cooking spray
- ½cup/113 grams unsalted butter (1 stick), sliced into ½-inch pieces
- 1¼cups/200 grams semisweet chocolate chips, plus more for topping
- 1cup/200 grams granulated sugar
- 3large eggs
- 1cup/150 grams mochiko (sweet rice flour), such as Blue Star brand
Preparation
- Step 1
Spray an 8-inch square cake pan with nonstick spray and line with parchment paper. Heat oven to 350 degrees.
- Step 2
To a large microwave-proof bowl, add the butter and chocolate and microwave on high for 1 minute. Give it a quick stir and microwave for another 15 seconds. Stir well until the chocolate is all melted and well combined with the butter.
- Step 3
To the chocolate and butter, add the sugar and stir well until combined. Add the eggs and stir (or use a whisk but a wooden spoon or flexible spatula is fine) until the eggs are completely combined. Lastly, add the mochiko and stir until you have a thick batter. Pour into the prepared pan, then tap it against the counter to get rid of any air bubbles. Scatter with a few more chocolate chips.
- Step 4
Place in the oven and bake until the center is dry to the touch but with a slight wobble when you press it, about 30 minutes. Cool completely in the pan on a wire rack. Use the parchment paper to slide the cooled mochi brownie out of the pan and allow to cool completely, 1 to 1 ½ hours. Cut the brownie into 16 pieces. (Mochi brownies can be stored in an airtight container at room temperature for up to 3 days or frozen for 3 months. To reheat from frozen, microwave for 30 seconds or longer until warm.)

A cooking time note for my half batch friends: this can be easily made in an 8x4 loaf tin at 350 for 22 minutes. I know because I am hovering over my mochi brownies eagerly waiting for them to cool. The scale is your friend here.
Instead of spraying the baking pan with some oil, I would recommend using the wrapper from the butter that you will be melting.
Having made these twice and read through the comments, I believe some people are simply using rice flour versus Mochiko flour which are two fairly different things. I would highly recommend reaching for the Mochiko flour and seeking it out at a local grocery store, Hmart, or Amazon. If you go with regular rice flour, that will yield a rather grainy/rice-flavored brownie. These are a bit sweet, though, and I would definitely cut the sugar by 1/3-1/2.
I made exactly as directed and they turned out good! I just cooked for 30 minutes in oven and didn’t bother checking the wobble or whatever. It was fun to find a Japanese market and get mochiko, and these came together very quick and easy, not much harder to make than boxed brownies, but way better. I didn’t think they were overly sweet and I don’t think you need to add salt and vanilla and whatever. Just make it the way it’s written and enjoy it for what it is. Solid 4 stars.
Very good brownie recipe, and very simple. I like how rich and fudgy these are; very good use of mochiko! My recommendations, however, are the addition of salt and vanilla. 1/4-1/2 tsp each. This will definitely help with the flavor and break up that rich chocolaty-ness. I also would recommend adding something to break up the texture, like chocolate chips in the batter or nuts of some kind. The mochi created a very even, kinda boring texture that would benefit from a little pizzazz.
I made these yesterday, VERY rich. I cut each Brownie in 4's and eat it as fudge bite! It is intensely chocolate and quite sweet. It is more fudgy than Brownie. The crumble is sticky, so while I don't get the descriptive "tender" it is definitely chewy. I baked for 30 minutes in an 8x8 glass dish and it could have used a good 10 minutes more. It seemed dry in the middle, with a bit of jiggle, but once completely cooled, the 4 in the middle were gooey. Mochi flour here was difficult to find.
