Line a muffin tin with paper liners — this makes removing the frozen strawberry cheesecake bites so much easier. Mix graham cracker crumbs with melted butter and sugar until it looks like wet sand, then press about 1 tablespoon into the bottom of each liner. Pop the tin into the freezer for 10 minutes while you prep the filling.
Beat room-temperature cream cheese with powdered sugar until it's completely smooth and fluffy, which takes about 2–3 minutes with an electric mixer. Scrape down the bowl halfway through because there's always cream cheese hiding in the corners. Add vanilla bean paste and lemon juice, then beat again until you don't see any lumps.
Pour heavy whipping cream into a separate bowl and whip it until you get stiff peaks — this takes about 3–4 minutes with an electric mixer on high. This is your secret to making these bites so light and creamy instead of dense and heavy like regular cheesecake.
Gently fold the whipped cream into the cream cheese mixture using a rubber spatula, being super careful not to deflate all those air bubbles you just created. Fold slowly in thirds and stop as soon as you don't see white streaks. Over-mixing kills the fluffy texture, so less is more here.
Fold in diced strawberries, strawberry jam, and orange zest until just combined — you want little bursts of fruit throughout. The mixture should look like pale pink clouds with strawberry pieces peeking through. I personally don't like to overmix at this stage because the frozen strawberry cheesecake bites taste better when the fruit stays in chunks.
Spoon the filling into each lined cup until it's about three-quarters full, then top each with a pinch of crushed pistachios. The toppings are key because they add that fancy restaurant touch without any extra effort. Freeze for at least 4 hours, though overnight is honestly better.
Pop them out of the liners when you're ready to serve — they should come out cleanly because the paper actually helps. Let them sit at room temperature for 2–3 minutes if they're too hard to bite through easily. Store extras in an airtight container in the freezer for up to two weeks.
