Combine graham cracker crumbs and melted butter in a bowl until the mixture resembles wet sand.
Press 1 tablespoon (15g) of crust mixture firmly into the bottom of 24 mini muffin cups or silicone molds. Chill while preparing the filling.
Beat softened cream cheese and sugar on medium speed until smooth and creamy, 2 to 3 minutes. Scrape bowl sides as needed.
Add vanilla and lemon juice, mix until incorporated.
In a separate bowl, whip heavy cream to stiff peaks. Gently fold into the cream cheese mixture until uniform.
Spoon or pipe filling over crusts, filling each about three quarters full. Smooth tops.
Chill for at least 3 hours or overnight. Top with berries before serving.
