Chocolate Malt Bars are creamy, chocolatey dessert bars with rich chocolate malt powder, set over a buttery Oreo cookie crust and topped with crushed malted milk balls. This no-bake treat delivers all the flavors of a classic chocolate malt milkshake in a cool, satisfying bar form—perfect for parties, potlucks, or a sweet after-dinner indulgence.
Line an 8x8-inch baking dish with parchment paper, allowing the sides to overhang for easy removal.
In a small bowl, combine the crushed Oreo cookies and 4 tablespoons of melted butter. Press firmly into the bottom of the prepared dish. Chill in the refrigerator while preparing the filling.
In a medium saucepan over medium-low heat, melt 2 tablespoons of butter. Add marshmallows, chocolate chips, and salt. Stir until marshmallows are just melted and smooth. Remove from heat and let cool for 5-8 minutes until slightly thickened.
In the bowl of a stand mixer with the paddle attachment, beat cream cheese, confectioners' sugar, chocolate malt powder, and vanilla until smooth and creamy.
Switch to the whisk attachment. With the mixer on low, pour in the heavy cream. Whip until the mixture is light, fluffy, and fully combined.
Gradually fold the cooled marshmallow-chocolate mixture into the whipped cream base. Mix until fully incorporated.
Pour the filling over the chilled crust, spreading it into an even layer. Sprinkle the top with crushed malted milk balls.
Refrigerate the bars for 3-4 hours, or until completely set. Lift out with parchment, slice into squares, and serve cold.
Notes
For best results, chill the bars for at least 4 hours or overnight. Store leftovers in an airtight container in the refrigerator for up to 5 days.
