Ingredients You'll Need
For the Bars
1 cup unsalted butter, melted
2 cups graham cracker crumbs
1 can sweetened condensed milk, 14 ounces

That's the complete ingredient list.

Tools You'll Need
You don't need much equipment for this recipe.
9x13-inch clear glass baking dish
Medium mixing bowl
Spoon or spatula
Measuring cups
Parchment paper, optional
Sharp knife for slicing
A clear glass baking dish is specifically used in the recipe. Lightly grease it, or line it with parchment paper if you'd like to lift the finished bars out more easily.
Ingredient Variations and Substitutions
The basic recipe is delicious as written, but there are a few easy ways to change things up.
Use Different Chocolate Chips
For extra chocolate flavor, replace ½ cup of the semi-sweet chocolate chips with either milk chocolate or dark chocolate chips.
Milk chocolate can make the bars a little sweeter, while dark chocolate gives them a richer flavor.
Add a Little Flaky Salt
A light sprinkle of flaky salt over the bars immediately after baking creates a salty-sweet contrast.
It's a tiny addition, but it can make the dessert feel a little more special.
Adjust the Malted Milk Balls
If whole malted milk balls feel too chunky for younger children, roughly chop some of them while leaving the rest whole.
That way, you still get the malty crunch without having every piece quite as large.
How to Make Malted Milk Crunch Bars
Step 1: Prepare the Baking Dish
Preheat your oven to 350°F.
Lightly grease a clear glass 9x13-inch baking dish.
For easier removal and slicing later, you can line the dish with parchment paper instead.
Step 2: Make the Graham Cracker Crust
Add the melted butter and graham cracker crumbs to a medium bowl.
Stir until the crumbs are evenly moistened.
Transfer the mixture to the prepared baking dish and press it firmly into the bottom.
Try to create an even layer so the finished bars have a consistent crust.
Step 3: Add the Condensed Milk
Pour the 14-ounce can of sweetened condensed milk evenly over the graham cracker crust.
Take your time with this step so the condensed milk is distributed across the surface.
Step 4: Add the Chocolate and Malted Milk Balls
Sprinkle the 2 cups of semi-sweet chocolate chips over the condensed milk.
Then scatter the 3 cups of whole unwrapped malted milk balls evenly across the dish.
Now you can really see what these bars are going to become!
Step 5: Bake
Place the baking dish in the preheated oven.
Bake for 22 to 26 minutes, or until:
The edges are lightly golden
The chocolate is melted
The malted milk balls look glossy on the outside
The center appears set
Keep an eye on the edges toward the end of the baking time.
Step 6: Cool and Slice
Remove the dish from the oven and allow the bars to cool in the pan until they're firm enough to slice cleanly.
Cut into 16 squares.
You can serve them as they are, or refrigerate them for a firmer, crunchier texture.
What to Serve With Malted Milk Crunch Bars
These bars are sweet enough to stand on their own, but a few simple pairings make them even more enjoyable.
For a Classic Treat
Serve them with a cold glass of milk.
It's hard to go wrong with that combination.
With Coffee or Hot Cocoa
The chocolate and malt flavors pair nicely with coffee or a mug of hot cocoa.
This makes them especially cozy for movie nights or relaxed evenings at home.
With Vanilla Ice Cream
Want to turn these simple bars into a more dressed-up dessert?
Serve one slightly warm with a scoop of vanilla ice cream.
The contrast between the warm bar and cold ice cream is a delicious way to serve them.
Add Fresh Fruit
Fresh strawberries or raspberries on the side can provide a bright contrast to the sweetness of the bars.
Tips for Making the Best Malted Milk Crunch Bars
Press the Crust Firmly
Don't simply scatter the graham cracker mixture into the pan. Press it firmly and evenly across the bottom.
A well-pressed crust gives the bars a more cohesive base.
Don't Overbake
The recipe calls for 22 to 26 minutes.
Watch the edges toward the end. The goal is lightly golden edges, melted chocolate, glossy malted milk balls, and a settled center—not a dry-looking top.
Remember That Glass Holds Heat
The glass baking dish can retain heat after the bars come out of the oven.
That's another reason to avoid leaving them in the oven longer than necessary. The bars will continue setting as they cool.
Refrigerate for Cleaner Slices
If you're preparing these for a party or dessert tray, let them cool completely and refrigerate them for 30 to 60 minutes before cutting.
A sharp knife wiped clean between slices can help create neat squares.
Keep Some Malted Milk Balls Whole
The whole malted milk balls are part of what makes these bars fun.
If you're modifying the recipe for younger kids, chop some while leaving others whole so you get a mixture of textures.
How to Store the Bars
The source recipe does not provide specific long-term storage instructions or a defined storage duration.
For the texture described in the recipe, the bars can be chilled for a firmer, crunchier texture before serving.
If you're preparing them ahead for a gathering, chilling also makes them easier to slice neatly.
