-
1 teaspoon vanilla extract

2 1/2 cups (300 g) crushed vanilla wafers or graham crackers

-
1/4 teaspoon salt
For the Frosting

1/2 cup (113 g) unsalted butter, softened

1 teaspoon vanilla extract

Instructions
Before starting, heat-treat the flour by microwaving it for 1–2 minutes, stirring every 30 seconds, or baking at 350°F (175°C) for 5 minutes. Allow it to cool completely.
In a large bowl, whisk together the melted butter, granulated sugar, milk, and vanilla extract until smooth and well combined.
Stir in the crushed vanilla wafers or graham crackers, heat-treated flour, and salt. Mix until a thick, soft dough forms.
Line an 8×8-inch or 9×9-inch pan with parchment paper. Press the dough evenly into the pan, smoothing the top with a spatula.
Refrigerate the cookie base for 30–45 minutes, or until firm enough to frost.
In a mixing bowl, beat the softened butter until creamy. Gradually add powdered sugar, milk, and vanilla extract, beating until smooth and spreadable.
Spread the frosting evenly over the chilled cookie base using an offset spatula.
Immediately top with Christmas sprinkles, sanding sugar, or festive candy shapes.
Refrigerate for an additional 30 minutes to set the frosting. Lift from the pan and slice into bars.
Notes
-
Always heat-treat flour for no-bake recipes.
-
Press the base firmly for clean slices.
-
Chill thoroughly for best structure.
-
Frost only after the base is fully set.
-
Decorate immediately so sprinkles adhere.
