Step-by-Step Cooking Instructions
Step 1: Prepare the Crust
Line an 8×8-inch baking dish with parchment paper for easy removal. In a mixing bowl, combine the crushed graham crackers and melted butter. Stir until the mixture resembles wet sand.
Press it firmly into the bottom of the dish, ensuring an even layer. Place in the refrigerator to chill while you prepare the filling.
Step 2: Whip the Cream
In a large bowl, use a hand mixer to whip the heavy cream until stiff peaks form. Set aside.
Step 3: Make the Marshmallow Filling
In another bowl, beat the softened cream cheese, powdered sugar, and vanilla extract until smooth and creamy. Gently fold in the whipped cream, mixing until fully incorporated.
Step 4: Add the Marshmallows & Chocolate Chips
Fold in the mini rainbow marshmallows and white chocolate chips (if using), ensuring they are evenly distributed throughout the mixture.
Step 5: Assemble the Slice
Spread the marshmallow filling evenly over the chilled crust, smoothing the top with a spatula. Cover and refrigerate for at least 4 hours, or until firm.
