How to Make Malted Milk Ball Dessert Bars

1. Preheat the oven to 350°F. Lightly grease a rimmed sheet pan or line it with parchment paper for easy cleanup.
2. In a medium bowl, combine the crushed graham crackers and melted butter. Mix until the crumbs are evenly coated, then press the mixture into an even layer across the bottom of the prepared sheet pan.
3. Sprinkle the mini marshmallows evenly over the graham cracker crust. Add the whole malted milk balls on top, spreading them across the pan so every serving has a crunchy candy bite.
4. Slowly drizzle the sweetened condensed milk over the marshmallows and malted milk balls. Try to cover as much of the surface as possible for a rich, gooey texture.
5. Bake for 18 to 22 minutes, or until the marshmallows are puffed, lightly golden, and the edges are bubbling.
6. Let the dessert cool for at least 20 minutes before slicing into bars or breaking into rustic pieces. Serve warm or chilled.

Serving Ideas

Serve these easy dessert bars with vanilla ice cream, fresh strawberries, sliced bananas, or a cold glass of milk. They are also delicious on a dessert table with lemonade, iced coffee, fresh fruit, or other summer party snacks.

Tips and Variations

For a richer chocolate flavor, sprinkle ½ cup of semisweet chocolate chips over the marshmallows before baking. The chocolate melts into the dessert and gives these bars a delicious s’mores-inspired taste.

For thicker and gooier malted milk ball bars, use a smaller baking pan. A larger sheet pan creates thinner, crispier pieces that cool quickly and are easy to transport.

For clean slices, allow the bars to cool completely, then refrigerate them for 20 to 30 minutes before cutting. This is especially useful when preparing the dessert ahead of time for a picnic, potluck, or family gathering.

You can also replace the graham cracker crumbs with crushed vanilla wafers, chocolate cookies, or digestive biscuits for a different flavor and texture.

Storage

Store leftover malted milk ball dessert bars in an airtight container at room temperature for up to 2 days. For a firmer texture, keep them in the refrigerator. Warm individual servings in the microwave for a few seconds to bring back their soft, gooey, freshly baked texture.
