This ultra-chewy malted brownie recipe transforms simple ingredients into bakery-quality treats with the nostalgic flavor of malted milk. The brown butter adds a nutty depth while the malted milk powder creates that distinctive sweet, toasty taste that makes these brownies truly exceptional.
I created this recipe during a weekend when my usual box mix was nowhere to be found, and it has become our family's go-to brownie recipe. The first time my daughter tried these, she declared them the only brownies she ever wants to eat again.

Step-by-Step Instructions
- Prepare the Pan:
- Preheat your oven to exactly 325°F not hotter or the edges will overcook before the center sets. Line your metal pan with parchment creating handles for easy removal and spray lightly with cooking spray to ensure nothing sticks.
- Brown the Butter:
- In a small saucepan over medium-low heat melt the butter completely then increase to medium heat. Watch carefully as the butter foams swirling occasionally until you see amber bits forming at the bottom and smell a nutty aroma. Immediately transfer to your mixing bowl making sure to scrape in all those flavorful brown bits.
- Create the Base:
- Add powdered sugar to the hot browned butter and stir until it forms a thick paste. Let this mixture cool for about 5 minutes until barely warm to prevent cooking the eggs. This cooling step is crucial for the perfect texture.
- Mix the Wet Ingredients:
- Vigorously whisk in the cold eggs egg yolk and vanilla for a full 30 seconds. The mixture should become smooth glossy and noticeably lighter in color. This intense whisking creates that beautiful crackly top.
- Add Dry Ingredients:
- Switch to a spatula and gently fold in the cocoa powder until fully incorporated. Then add the flour malted milk powder cornstarch and salt mixing just until no dry streaks remain. Fold in the chocolate chips with just a few strokes. The batter will be very thick almost like a dough.
- Bake to Perfection:
- Spread the batter evenly into your prepared pan using the spatula to push it into the corners. Bake for exactly 30 to 33 minutes. The brownies are done when the center is set but a tester comes out with moist crumbs attached not wet batter. Remember they will continue cooking from residual heat.
The malted milk powder is truly the star ingredient here. I discovered its magic when experimenting with ways to recreate that nostalgic soda fountain flavor my grandmother always loved. Whenever I make these the kitchen fills with an aroma that immediately takes me back to childhood visits to her house where treats were always waiting.
Perfect Storage
These brownies actually improve with a day of rest as the flavors meld together. Store them in an airtight container at room temperature for up to 3 days. For longer storage keep them in the refrigerator where they'll last up to 5 days. The chilled brownies become even fudgier which some family members prefer. You can also freeze them individually wrapped for up to 3 months just thaw at room temperature for about an hour before serving.
Easy Substitutions
If you don't have malted milk powder you can substitute nonfat dry milk powder though the distinctive malt flavor will be missing. For a dairy-free version replace butter with coconut oil and use dairy-free chocolate chips but note the texture will be slightly different. Dutch-process cocoa can replace natural cocoa for a deeper color and slightly different flavor profile. For gluten-free brownies use a 1-to-1 gluten-free flour blend but add an extra tablespoon to maintain structure.
Serving Suggestions
These brownies shine on their own but transform into a decadent dessert when served warm with a scoop of vanilla ice cream. For the ultimate treat crumble them over malted milk ice cream. At parties I cut them into smaller two-bite squares and arrange them on a platter with fresh berries. For a special occasion drizzle with warm caramel sauce and a sprinkle of crushed malted milk balls.
The Science Behind the Chew
The unique combination of powdered sugar brown butter and malted milk powder creates the perfect chewy brownie texture. Powdered sugar contains cornstarch which contributes to tenderness while the proteins in the malted milk powder enhance chewiness by creating additional structure. The brown butter adds fat that coats the flour proteins preventing them from forming too much gluten which would make the brownies tough rather than tender.
