Leftover S'Mores Pie - cooking recipe

Ingredients

3 (4.8 ounce) packages graham crackers, crushed
6 tablespoons butter, melted
1/4 cup white sugar
1/4 (10 ounce) package marshmallows, or more to taste
6 cups milk
2 (3.5 ounce) packages instant vanilla pudding mix
1 banana, sliced
1/4 (12 ounce) package vanilla wafer cookies (such as Nilla(R))
1 tablespoon chocolate syrup, or to taste

Preparation

Preheat oven to 350 degrees F (175 degrees C).
Pour crushed graham crackers into a 9x13-inch baking dish. Mix butter and sugar into the graham crackers using your hands until crumbs are moist; press into the dish forming a crust.
Arrange marshmallows in the crust, leaving space between each marshmallow.
Whisk milk and pudding mix together in a bowl until pudding thickens, 1 to 2 minutes. Pour pudding over marshmallows. Arrange banana slices and vanilla wafer cookies atop the pudding.
Bake in the preheated oven until marshmallows melt, 20 to 30 minutes. Drizzle with chocolate syrup.
