Preheat oven to 325°F (160°C). Line a 12-cup muffin tin with paper liners.
Mix graham cracker crumbs, 1/4 cup sugar, and melted butter. Press 1 tablespoon of the mixture firmly into the bottom of each liner.
Bake crusts for 5-7 minutes. Let cool completely.
Whip the heavy cream to stiff peaks in a separate chilled bowl. Set aside.
Beat the softened cream cheese and 1/2 cup sugar until completely smooth. Mix in vanilla and lemon juice.
Gently fold the whipped cream into the cream cheese mixture. Divide evenly among the cooled crusts.
Refrigerate for at least 4 hours (preferably overnight) until fully set.
Before serving, toss diced strawberries and kiwis in the fruit glaze and top each mini cheesecake.
