Step 1: Prepare the Graham Cracker Crumbs

1. In a bowl combine:
   • Graham cracker crumbs
   • Melted butter
   • Sugar
   • Pinch of salt
2. Stir until evenly moistened.

Texture Check

The mixture should resemble wet sand and hold together when pressed.

Set aside.

Step 2: Make the Cheesecake Base

1. Place softened cream cheese in a large mixing bowl.
2. Beat for 2–3 minutes until completely smooth.

Scrape down the bowl frequently.

3. Add:
   • Powdered sugar
   • Key lime zest
4. Beat until fluffy.
5. Add:
   • Key lime juice
   • Vanilla extract
6. Mix until fully incorporated.

The mixture may look slightly loose—that’s normal.

Step 3: Whip the Cream

1. In a separate cold bowl, add:
   • 1 cup cold heavy cream
2. Beat on medium-high speed until stiff peaks form.

Stiff Peaks Test

When the beaters are lifted, the whipped cream should stand upright without collapsing.

Step 4: Create the Mousse

1. Add one-third of the whipped cream to the cream cheese mixture.
2. Fold gently with a spatula.

This lightens the base.

3. Add the remaining whipped cream in two additions.
4. Fold gently until smooth and fluffy.

Avoid overmixing to maintain the airy texture.

Step 5: Prepare the Whipped Cream Topping

   • 1 cup heavy cream
   • Powdered sugar
   • Vanilla
2. Beat until medium-stiff peaks form.

Transfer to a piping bag if desired.
