Line a mini muffin tin with paper liners first — trust me, trying to pop them out later is frustrating. Mix together 1 cup graham cracker crumbs, 1/4 cup melted butter, and 1/4 cup granulated sugar until it looks like wet sand. Press about 1 tablespoon of the mixture firmly into each liner to create your crust base. You'll want that bottom layer nice and compact.

Beat 16 oz softened cream cheese for about 2 minutes until it's super fluffy and smooth. Scrape down the sides with a spatula because cream cheese loves to hide in the corners. Add 1/4 cup fresh lemon juice, 2 tbsp lemon zest, 1 tsp vanilla extract, and 1/4 tsp salt. Mix on medium speed for another minute until everything is combined and bright yellow.

Pour 1 cup heavy cream into a separate clean bowl and whip it by hand or with an electric mixer until you get stiff peaks. This takes about 3-4 minutes if you're using a mixer, longer if you're doing it by hand (yes, I've been there). Don't skip this step because the whipped cream is what makes frozen lemon cheesecake bites so light and airy instead of dense.

Fold the whipped cream into the lemon cream cheese mixture gently using a spatula — don't overmix or you'll deflate all those beautiful air bubbles. Sprinkle in 1 tsp agar-agar powder and fold that in too, working slowly so there are no lumps. This powder keeps everything creamy when frozen instead of getting those weird ice crystals.

Whisk together 1/2 cup powdered sugar separately, then fold it into the lemon mixture just until combined. Taste it now and add more lemon juice if you want it tangier — I usually add an extra tablespoon. The filling should taste pretty lemony and just slightly sweet because the graham cracker base adds more sweetness.

Spoon the lemon filling into each prepared liner, filling each one about three-quarters full. Use a small cookie scoop if you have one because it makes everything consistent and honestly just faster. Top each bite with a tiny pinch of lemon zest for that fancy presentation moment. Pop the whole tin into the freezer for at least 4 hours, but overnight is even better.

Once completely frozen, you can pop them out of the liners and store them in an airtight container in the freezer for up to 2 weeks. They thaw for about 10 minutes at room temperature before serving, which is the perfect amount of time to plate everything else. I always pull mine out of the freezer about 5 minutes before guests arrive for that ideal texture.
