Step-by-Step Instructions

1. Prepare the Watermelon
Start with about 2 cups cubed seedless watermelon. Blend until smooth, then strain through a fine mesh sieve to remove pulp. You’ll need:
-
½ cup watermelon juice
Let it chill in the fridge while you prep the other ingredients.
2. Make the Crust
In a bowl, combine:
-
1½ cups graham cracker crumbs
-
6 tbsp melted butter
-
1 tbsp sugar (optional)
Mix until the texture resembles wet sand. Press firmly into the bottom of a 9-inch springform pan. Chill in the freezer for 15–20 minutes.
3. Whip the Cream
In a cold bowl, whip:
-
1 cup heavy cream
Beat to soft peaks. Set aside in the fridge.
4. Make the Cheesecake Base
In another bowl, beat until smooth:
-
16 oz (2 blocks) cream cheese
-
½ cup powdered sugar
-
1 tsp vanilla extract
-
1 tbsp fresh lime juice
-
½ cup strained watermelon juice
Beat until fluffy and smooth. Gently fold in the whipped cream until fully incorporated.
5. Assemble and Chill
Pour the watermelon cheesecake filling over the chilled crust. Smooth the top with a spatula.
Cover and refrigerate for at least 6 hours or overnight for best set.

FAQs
Q1: Can I make this ahead?
