Ingredients

Dry Ingredients:

• 1 cup mochiko flour (sweet rice flour)
• ½ cup cocoa powder
• 1 teaspoon baking powder
• ½ teaspoon salt

Wet Ingredients:

• ¾ cup granulated sugar
• ½ cup brown sugar
• ½ cup unsalted butter, melted
• ½ cup milk (or coconut milk for dairy-free option)
• 2 eggs
• 1 teaspoon vanilla extract
• ½ cup melted dark chocolate

Optional Add-ins:

• ½ cup chopped walnuts or pecans
• ½ teaspoon espresso powder (for richer chocolate flavor)
• ¼ cup chocolate chips

Step-by-Step Instructions

Step 1: Preheat and Prepare the Baking Dish

Preheat your oven to 350°F (175°C). Lightly grease a 9×9-inch baking pan and line it with parchment paper for easy removal.

Step 2: Mix the Dry Ingredients

In a large bowl, whisk together the mochiko flour, cocoa powder, baking powder, and salt until well combined. This helps evenly distribute the dry ingredients, ensuring a smooth batter.

Step 3: Melt the Butter and Chocolate

In a microwave-safe bowl, melt the butter and dark chocolate together in 30-second intervals, stirring in between. Once melted, let it cool slightly before adding to the batter.

Step 4: Combine the Wet Ingredients

In another bowl, whisk together the granulated sugar, brown sugar, eggs, vanilla extract, and milk until smooth. Slowly pour in the melted butter and chocolate mixture, whisking continuously.

Step 5: Incorporate Dry and Wet Mixtures

Gradually fold the dry ingredients into the wet mixture, stirring until a thick, smooth batter forms. If using add-ins like chocolate chips or nuts, gently fold them in now.

Step 6: Bake the Brownies

Pour the batter into the prepared baking dish, spreading it evenly. Bake for 40–45 minutes, or until the top is set and slightly cracked. A toothpick inserted should come out with a few moist crumbs (not wet batter).

Step 7: Cool and Slice

Allow the brownies to cool completely in the pan before slicing. This ensures they set properly and maintain their chewy texture. For best results, chill in the refrigerator for 30 minutes before cutting.

Ingredient Background

• Mochiko Flour – The key ingredient that gives these brownies their signature chewiness.
• Cocoa Powder & Dark Chocolate – A combination that deepens the chocolate flavor.
• Brown Sugar – Adds moisture and caramel undertones.
• Eggs – Help create structure and a slightly cakey top.
• Milk – Keeps the brownies soft and tender.

Technique Tips

• Don’t Overbake – Mochi brownies will continue to set as they cool.
• Use High-Quality Chocolate – For the richest flavor, use good-quality dark chocolate.
• Let Them Cool Completely – This improves the texture and chewiness.

Alternative Presentation Ideas

Additional Tips for Success

Frequently Asked Questions

1. Can I make this recipe dairy-free?

Yes! This recipe can be easily adapted for a dairy-free version without sacrificing flavor or texture. Instead of butter, use coconut oil, vegan butter, or a neutral oil like avocado oil. For the milk, swap in coconut milk, almond milk, or oat milk. If you want to keep the rich taste, full-fat coconut milk is the best option, as it adds a slight creaminess to the batter.

Additionally, make sure your chocolate chips or dark chocolate are dairy-free if you’re using them in the recipe. Many brands offer vegan-friendly chocolate, which works perfectly for mochi brownies.

2. Why are my mochi brownies too hard?

If your mochi brownies turned out too firm or tough, there are a few possible reasons:

• Overbaking – Mochi brownies continue to firm up as they cool, so if they’re left in the oven too long, they can become overly dense and dry. Bake only until the center is slightly soft and the edges look set.
• Incorrect flour – If you used regular rice flour instead of mochiko sweet rice flour, the texture will be completely different. Mochiko is essential for the chewiness.
• Not enough liquid – Mochi brownies require a good balance of moisture. If you used less milk than called for or skipped an ingredient like eggs, it could lead to a harder texture.
• Cooling too fast – Let the brownies cool gradually at room temperature. Placing them in the fridge immediately can cause them to harden too quickly.

To soften hardened mochi brownies, microwave them for 10–15 seconds before serving. This will help bring back some of the chewy texture.

3. Can I use regular flour instead of mochiko?

No, regular flour cannot be substituted for mochiko in this recipe. Mochiko (sweet rice flour) is made from glutinous rice, which gives the brownies their signature chewiness. Regular wheat flour or even normal rice flour does not contain the same sticky, elastic properties and will result in a dry, crumbly texture.

If you don’t have mochiko, look for another brand of glutinous rice flour, but make sure it’s labeled “sweet rice flour” or “glutinous rice flour” (not just rice flour). Some popular brands include:

• Koda Farms Mochiko (USA)
• Erawan Brand Glutinous Rice Flour (Thailand)
• Shiratamako (Japanese Glutinous Rice Flour, often used for mochi desserts)

4. What’s the difference between sweet rice flour and regular rice flour?

Though they sound similar, sweet rice flour (mochiko) and regular rice flour are very different:

• Sweet rice flour (mochiko): Made from glutinous rice (sticky rice), it has a chewy, stretchy, and slightly elastic texture. It’s often used in mochi, butter mochi, and chewy baked goods.
• Regular rice flour: Made from long-grain or medium-grain rice, it has a dry, powdery texture and is mainly used for crispier baked goods or as a thickening agent.

For this recipe, only mochiko or glutinous rice flour will work. Using regular rice flour will result in a completely different texture.

5. Can I reduce the sugar?

Yes! If you prefer a less sweet version, you can reduce the sugar by ¼ cup without significantly affecting the texture. Here are some sugar reduction tips:

• Use ½ cup granulated sugar instead of ¾ cup.
• Reduce brown sugar slightly but keep it for moisture and depth of flavor.
• If you reduce sugar too much, add 1 tablespoon of honey or maple syrup for moisture balance.

For a low-sugar option, consider using monk fruit sweetener or coconut sugar instead of white sugar. Keep in mind that reducing sugar may slightly change the texture, making the brownies a little less soft and gooey.

6. How do I store mochi brownies?

Mochi brownies stay soft and chewy for days, but proper storage is key:

• At room temperature: Store in an airtight container for up to 3 days. Keep them in a cool, dry place.
• Refrigerator: Store for up to 5 days. They may become firmer in the fridge, so microwave them for 10–15 seconds before eating to restore their chewiness.
• Freezer: Wrap individual pieces in plastic wrap, then place them in a ziplock bag. Freeze for up to 3 months. To eat, thaw at room temperature or microwave for a few seconds.

7. How can I make these brownies extra fudgy?

If you love super fudgy mochi brownies, try these tips:

• Add an extra egg – This makes the brownies richer and slightly denser.
• Use more melted chocolate – Increase melted dark chocolate to ¾ cup for a deeper flavor.
• Add a splash of coffee – 1 teaspoon of espresso powder enhances the chocolate richness.
• Reduce baking time – Bake for 35–38 minutes instead of 45 minutes. The center will stay softer.

8. Can I add toppings or mix-ins?

Yes! Mochi brownies are very customizable. Try these fun add-ins:

• Chocolate chips – Stir in ½ cup for extra melty pockets of chocolate.
• Walnuts or pecans – Add a crunch to balance the chewiness.
• Shredded coconut – Pairs well with coconut milk for a tropical twist.
• Matcha powder – Replace 2 tablespoons of cocoa powder with matcha for a green tea flavor.
• Peanut butter swirl – Drop small spoonfuls of peanut butter on top and swirl with a knife before baking.

9. Can I make these brownies vegan?

Yes! Here’s how to make vegan chocolate mochi brownies:

• Replace eggs with flax eggs (1 tbsp flaxseed + 3 tbsp water per egg, let sit for 5 minutes).
• Use coconut oil or vegan butter instead of regular butter.
• Use dairy-free chocolate (check labels for vegan-friendly brands).
• Use plant-based milk such as almond, oat, or coconut milk.

These swaps will maintain the chewy texture while keeping the recipe completely plant-based.

10. Can I double the recipe?

Yes! If you’re baking for a crowd, double the recipe and bake in a 9×13-inch pan. You may need to increase the baking time by 5–10 minutes to ensure even cooking. If the top browns too quickly, cover loosely with foil for the last 10 minutes.
