Ingredients
-
1 cup unsalted butter (2 sticks), browned
-
1 ¼ cups granulated sugar
-
½ cup light brown sugar, packed
-
4 large eggs, at room temperature
-
2 tsp pure vanilla extract
-
¾ cup all-purpose flour
-
½ cup mochiko (sweet rice flour)
-
½ cup unsweetened cocoa powder
-
½ tsp salt
-
1 cup semi-sweet chocolate chips
-
Optional: ½ cup chopped nuts (walnuts or pecans)
Each ingredient plays a critical role: brown butter brings nutty richness, mochiko provides chewiness, and chocolate chips add pockets of melty decadence. Using room-temperature eggs ensures a smoother batter, and the optional nuts give a satisfying crunch.
Pro Tips
-
Brown the Butter Carefully: Keep a close eye while browning your butter. Stir continuously over medium heat until it turns a golden brown with a nutty aroma. Remove immediately from heat to prevent burning. This step is crucial for developing flavor.
-
Mix Dry Ingredients Gently: Combine flour, mochiko, cocoa, and salt in a separate bowl before folding into wet ingredients. Avoid overmixing once combined to preserve a tender, fudgy texture.
-
Pan Prep Matters: Line your baking pan with parchment paper and lightly grease it. This ensures easy removal of the brownies without damaging the chewy edges or sticky interior.
Instructions
Step 1: Brown the Butter
In a medium saucepan, melt butter over medium heat. Stir constantly until it turns golden brown and releases a nutty aroma. Remove from heat and let it cool slightly while you prepare the other ingredients.
Step 2: Mix Sugars and Eggs
In a large mixing bowl, whisk together granulated sugar and brown sugar. Add the eggs one at a time, whisking thoroughly after each addition. Stir in vanilla extract.
Step 3: Combine Dry Ingredients
In a separate bowl, sift together all-purpose flour, mochiko flour, cocoa powder, and salt. This ensures an even distribution of dry ingredients and prevents clumping.
Step 4: Incorporate Butter
Slowly pour the cooled brown butter into the egg and sugar mixture while stirring continuously. Then fold in the dry ingredients gently using a spatula until just combined.
Step 5: Add Chocolate Chips and Nuts
Fold in the chocolate chips and optional chopped nuts, making sure they’re evenly distributed. This step adds bursts of melty chocolate and extra texture.
Step 6: Bake the Brownies
Preheat your oven to 350°F (175°C). Pour the batter into a prepared 9×9-inch baking pan and smooth the top. Bake for 35–40 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. Avoid overbaking to maintain fudginess.
Step 7: Cool and Serve
Allow the brownies to cool in the pan for at least 20 minutes. Lift out using the parchment paper and transfer to a wire rack. Slice into squares and enjoy warm for the meltiest experience, or chill slightly for a firmer texture.

Variations
-
White Chocolate Mochi Brownies: Substitute semi-sweet chocolate chips with white chocolate chunks for a creamier, sweeter flavor.
-
Vegan Adaptation: Replace butter with coconut oil and use flax eggs (1 tbsp flaxseed meal + 3 tbsp water per egg) to make a vegan version.
-
Spiced Mochi Brownies: Add ½ tsp cinnamon and a pinch of cayenne pepper to the dry ingredients for a subtle warmth that complements chocolate.
Storage and Serving
Store Fudgy Brown Butter Mochi Brownies in an airtight container at room temperature for up to 4 days. For longer freshness, refrigerate for up to a week or freeze for up to 2 months.
Serving ideas:
-
Warm with a scoop of vanilla ice cream and a drizzle of chocolate sauce.
-
Cut into small squares and serve alongside coffee or tea for a decadent afternoon treat.
-
Sprinkle with sea salt and crushed nuts for a sophisticated dessert presentation.
FAQs
1. Can I use regular flour instead of mochiko?
Using all-purpose flour alone will yield traditional brownies, but you’ll lose the chewy, mochi texture that makes these special.
2. Why are my brownies too dry?
Overbaking is the most common cause. Keep an eye on them and remove from oven when the toothpick shows moist crumbs.
3. Can I double this recipe?
Yes, double all ingredients and bake in a 9×13-inch pan. Adjust baking time to 45–50 minutes.
4. How do I get the fudgy top layer?
Brown the butter properly and avoid overmixing the batter. Also, don’t overbake, as this helps form the signature glossy, slightly crackled top.
5. Can I add mix-ins?
Absolutely! Chopped nuts, caramel bits, or toffee pieces can enhance flavor and texture. Just fold them in before baking.
