Ingredients
- 1 cup unsalted butter, melted
- 1 cup packed light brown sugar
- 2 cups all-purpose flour
- ¾ cup malted milk powder
- 1½ cups milk chocolate chips
Instructions
Step 1: Prepare the Baking Pan
Preheat the oven to 350°F (175°C). Line a 9-by-13-inch baking pan with parchment paper, leaving a little overhang on the sides for easy removal.
Step 2: Make the Malted Base
In a large mixing bowl, combine the melted butter and brown sugar. Stir until smooth.
Add the all-purpose flour and malted milk powder. Mix until a soft, crumbly dough forms and no dry patches remain.
Step 3: Press into the Pan
Transfer the mixture to the prepared baking pan. Press it evenly into the bottom using the back of a spoon or your hands.
Step 4: Bake
Bake for 18–22 minutes, or until the edges are lightly golden and the center looks set. Avoid overbaking to keep the bars tender.
Step 5: Add the Chocolate
Remove the pan from the oven and immediately sprinkle the milk chocolate chips evenly over the warm base.
Let them sit for 3–5 minutes to soften, then spread the melted chocolate into an even layer with a spatula.
Step 6: Cool and Slice
Allow the bars to cool completely at room temperature. Refrigerate briefly if needed to help the chocolate topping firm up.
Lift the bars out using the parchment paper and cut into squares or rectangles with a sharp knife.
Tips for the Best Malted Milk Chocolate Bars
- Use malted milk powder: Choose malted milk powder rather than malted drink mix, which may contain additional sugar and flavorings.
- Measure flour correctly: Spoon flour into the measuring cup and level it off to avoid a dry base.
- Don’t overbake: The base should be set but not deeply browned.
- Spread the chocolate while warm: This creates a smooth, even topping.
- Cool completely: Let the chocolate firm before slicing for cleaner edges.
Easy Variations
- Dark chocolate topping: Replace milk chocolate chips with dark chocolate chips for a less-sweet finish.
- Extra malt flavor: Sprinkle a little additional malted milk powder over the chocolate before it sets.
- Crunchy topping: Add chopped toasted almonds or crushed malted milk balls. These additions make it a version with more than five ingredients.
- White chocolate finish: Use white chocolate chips instead of milk chocolate for a sweeter variation.

Frequently Asked Questions
What is malted milk powder?
Malted milk powder is a blend of malted grain extract and milk ingredients. It gives desserts a distinctive sweet, toasted, milkshake-like flavor.
Can I use chocolate malt drink mix?
It is better to use plain malted milk powder. Chocolate drink mixes often contain extra sugar and cocoa, which can change the flavor and texture of the bars.
Can I use dark chocolate instead of milk chocolate?
Absolutely. Dark chocolate provides a richer, less-sweet topping that pairs nicely with the sweet malted base.
Why are my bars crumbly?
The flour may have been overmeasured, or the base may have been overbaked. Measure carefully and remove the pan once the center is set.
Can I make these bars ahead of time?
Yes. Bake them a day ahead, allow them to cool completely, and store them in an airtight container until serving.
