Preparation Method

Base Preparation
Crush crackers to fine crumbs. Combine with melted butter until mixture resembles wet sand. Press firmly into pan.
Cream Cheese Preparation
Beat cream cheese thoroughly until completely smooth and lump-free.
Cream Whipping
Using chilled equipment, whip cream to firm peaks, being careful not to overbeat.
Combining Components
Gently fold ingredients together until fully incorporated.
Final Assembly
Spread mixture evenly over prepared base, creating decorative swirls if desired.

The corner pieces, with their extra crust, are particularly popular. Consider making additional crust mixture for garnishing.

Recipe Development

The combination of marshmallows and cream cheese creates an exceptionally light, cloud-like texture. Through multiple iterations, proper timing and patience have proven essential for optimal results.

Serving Suggestions

Consider enhancing with a warm Nutella drizzle before serving. Fresh raspberries provide a pleasant tartness contrast, while crushed toffee adds textural interest.

Variations

Incorporate creamy peanut butter for nutty depth, crushed Oreos for texture, or seasonal additions like crushed candy canes during holidays. Fresh banana slices work well but should be added just before serving.

Storage Guidelines

Store covered in refrigeration for up to five days. Transport in an insulated container with ice packs. Cut while chilled for cleanest results.

Frequently Asked Questions

→ Can this be prepped in advance?
Absolutely, you can make it up to two days before and keep it chilled in the fridge.
→ Why is my cream cheese lumpy?
Make sure the cream cheese has fully warmed to room temperature before blending it.
→ Can this dessert be frozen?
It sure can! Freeze for up to three months, and allow it to thaw in the refrigerator overnight before serving.
→ What type of cookies make a good base?
Try using graham crackers, vanilla wafers, shortbread, or digestive biscuits.
→ Why do I need to chill the crust first?
Chilling gives the crust time to firm up, so it doesn’t mix in with your creamy filling when you layer it.
