Mix crushed graham crackers, butter (melt it first), and sugar until it looks like wet sand. Once combined, press this mixture firmly into the base of a 9-inch springform pan, making it as even as possible. Place the pan into the fridge to let it firm up while you move on to the next task.

Get a big bowl and blend softened cream cheese, sugar, and vanilla until it's all smooth and lump-free. In another bowl, whisk heavy cream until stiff peaks form, meaning it should hold its shape when you lift the whisk. Combine the whipped cream with the cream cheese mixture smoothly. Pour it over the chilled crust and level out the top. Chill for a good 2 hours or so.

Throw the blueberries, lemon juice, and sugar into a small pot. Warm it up over medium heat, stirring every now and then, until the blueberries break down and release their juice (this takes 5–7 minutes). Let it cool completely after lightly mashing or straining it smooth if you'd like. Whip some heavy cream until it forms stiff peaks. If you've got gelatin, dissolve it in warm water and stir it into the cooled blueberry mixture. Carefully fold the cream and blueberry mix together until it's blended and fluffy.

Once your cheesecake layer has set, spread the blueberry mousse across the top in an even layer. Put it back in the fridge and chill for at least 2–3 more hours until the whole thing is nice and set.

Take your cheesecake out of the springform pan gently after it's completely firm. Add a few fresh blueberries on top if you'd like and grab a plate to serve.
