Combine your graham cracker crumbs, melted butter, granulated sugar, and salt in a bowl and mix until it's the texture of wet sand. Press this mixture firmly into a 9-inch tart pan with a removable bottom, making sure you go up the sides evenly. Chill the crust for 15 minutes while you prep the filling—this helps it hold its shape.

Beat your softened cream cheese with powdered sugar until it's totally smooth and creamy, about 2-3 minutes with an electric mixer. This no bake blueberry lemon tart needs a light, fluffy filling, so don't rush this step. Scrape down the bowl halfway through to make sure everything combines evenly.

Stir in your lemon zest, fresh lemon juice, honey, and vanilla bean paste until everything is well incorporated. The filling should smell incredible at this point—seriously, that lemon aroma is chef's kiss. Taste it and adjust lemon juice if you want it brighter (I always do).

In a separate bowl, whip your heavy whipping cream to stiff peaks using an electric mixer—takes about 3-4 minutes. You want it thick enough to hold peaks when you lift the beaters out, not soupy.

Gently fold the whipped cream into your lemon mixture in two additions using a spatula, being careful not to deflate all those beautiful air bubbles. This folding technique is what keeps the no bake blueberry lemon tart so light and creamy instead of dense and heavy.

Pour the lemon cream filling into your chilled crust and spread it evenly across the top with an offset spatula or the back of a spoon. Refrigerate for at least 4 hours, though overnight is honestly better if you can wait that long.

Top with fresh blueberries just before serving—I arrange them in a pretty pattern, but honestly scattered works too. Slice with a warm, wet knife between each cut so you get clean edges and happy guests.
