These chewy chocolate mochi squares blend the rich taste of fudgy chocolate with mochi's unique bite. I stumbled upon this gem while hunting for a gluten-free twist on classic brownies, and it's become my favorite way to wow friends who think they've sampled every brownie type out there.

I first whipped these up during a wet, dreary weekend when I needed something different to tackle my chocolate cravings. The surprising texture totally won me over, and now I bake them whenever I want a dessert that gets people talking.

Ingredients

  • Mochiko flour: Creates that special chewy feel that makes these squares stand out
  • Unsweetened cocoa powder: Adds deep chocolate punch without making things too sweet
  • Granulated white sugar: Works with the cocoa and helps form that glossy top
  • Baking powder: Adds just a touch of rise without making them too fluffy
  • Unsalted butter: Brings moisture and flavor - try the fancy European kind for extra indulgence
  • Large eggs: Hold everything together while adding to that fudgy goodness
  • Whole milk: Gets the wetness just right - don't skimp with low-fat stuff
  • Vanilla extract: Boosts those chocolate notes - grab the real stuff, not fake
  • Chopped dark chocolate pieces: Make little pockets of intense flavor - go for 70% cocoa for best results

Step-by-Step Instructions

Prepare the Baking Pan:
Heat your oven to 350°F and put parchment in an 8x8 inch pan with extra hanging over the sides so you can lift it out later. The paper keeps things from sticking and makes cleanup super easy.
Mix the Dry Ingredients:
Put the mochiko flour, cocoa powder, sugar and baking powder in a bowl. Stir really well for about half a minute to get rid of lumps and mix the raising agent evenly. This stops any weird bitter spots from powder that didn't mix in.
Combine the Wet Ingredients:
Take a bigger bowl and mix the melted butter, eggs, milk and vanilla until everything looks the same color. Let the butter cool a bit first so it doesn't cook the eggs. You want it smooth and shiny.
Create the Batter:
Pour the dry stuff into the wet stuff and stir for a minute or two until it's all mixed. Don't worry if it seems runnier than normal brownie mix - that's how it should be. Just keep stirring until you can't see any dry patches and it's all one chocolate color.
Bake to Perfection:
Pour your mix into the pan and scatter the chocolate bits on top. Cook for 60-70 minutes, but watch carefully after an hour. They're done when the edges pull away from the pan a tiny bit and a toothpick comes out mostly clean with a few wet crumbs. Let them cool for at least 2 hours before cutting.

What I love most about these brownies is how the super chocolatey inside contrasts with the slightly crunchy top. The first time I brought them to a dinner with friends, they spent ages trying to figure out what made them so special before I told them the secret was mochi flour.

The Magic of Mochiko

Mochiko is just sweet rice flour, sometimes called glutinous rice flour even though it doesn't have any gluten. It's what makes these brownies so delightfully chewy, and they get even better the day after baking. The starch in mochiko builds a different structure than what you'd get from wheat flour brownies. If you can find it, grab the Japanese brand mochiko for the most authentic results, but any sweet rice flour will do the job.

Storage Instructions

These mochi brownies actually taste better with age. Keep them in a sealed container on your counter for up to 3 days, or in your fridge for a week. Putting them in the fridge makes them even chewier, more like traditional mochi. You can even freeze them for up to 3 months - just wrap each piece in plastic and put them in a freezer bag. Let them sit out for about an hour before you eat them.

Serving Suggestions

These mochi brownies taste great on their own, but they're even better with some vanilla ice cream or whipped cream to balance out how rich they are. For a fancy touch, sprinkle some powdered sugar on top right before serving, or drizzle some caramel over them. They go perfectly with afternoon coffee or tea, and their unusual texture always gets people talking.

Frequently Asked Questions

→ What is mochiko flour?

Mochiko flour comes from short-grain Japanese rice and is also known as sweet rice flour or glutinous rice flour. The name might trick you - it doesn't have gluten at all but gets called that because it turns sticky and chewy when you cook it. This special flour gives these brownies their bouncy, chewy feel that makes them so unique.

→ Can I substitute regular flour for mochiko flour?

Sadly, you can't swap in all-purpose flour for mochiko in this recipe. The bouncy, chewy texture only happens because of the sticky rice properties in mochiko. You'll spot mochiko flour at Asian markets or sometimes in the world foods section of bigger grocery stores.

→ Why do these brownies need to bake so long?

The brownies need 60-70 minutes because mochiko flour makes a super wet batter that takes its time to set up right. This longer bake makes sure the middle cooks through while creating that awesome chewy texture we want. Don't stress - they won't dry out like normal brownies would with such a long bake time.

→ How should I store mochi brownies?

Keep your mochi brownies in a sealed container at room temp for about 3 days. You can also pop them in the fridge for up to a week, though they'll get a bit firmer when cold. Just warm chilled brownies in the microwave for 10-15 seconds to bring back their soft, chewy goodness.

→ What's the texture difference between these and regular brownies?

Regular brownies are dense and rich but can fall apart easily. Mochi brownies have this cool stretchy, bouncy feel with a soft bite. They stay together better and have a nice springiness from the mochiko flour while still tasting super chocolatey. The texture reminds you a bit of mochi treats but with all that brownie flavor you love.

→ Can these brownies be frozen?

Absolutely! Mochi brownies freeze great. Just cut them into pieces, wrap each one in plastic, and tuck them into a freezer bag. They'll stay good for up to 3 months. Let them thaw on the counter or zap frozen ones in the microwave for 20-30 seconds when you need a quick sweet fix.
