Line a small cookie sheet with parchment paper. Combine cream cheese, sugar, and vanilla in a small bowl. Beat with an electric mixer on medium-high speed for about 2 minutes until fluffy and sugar is dissolved. Scoop into 18 portions (each 2 tsp) and flatten into discs. Freeze until completely firm.

Heat blueberries and sugar in a medium pot over medium heat. Cook for about 40 minutes, smashing halfway through. Stir continuously towards the end as the mixture thickens. Once reduced to about 1/2 cup (120 ml), chill in the fridge.

Preheat the oven to 350℉ (175℃) and line two baking sheets with parchment paper. In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside. In a large bowl, rub lemon zest into sugar, then cream with softened butter using an electric mixer until light and fluffy. Add the egg and vanilla, beating until pale and fluffy. Gradually mix in the dry ingredients until just combined.

Divide the dough into quarters. Flatten one-quarter in the bowl, spread one-quarter of the blueberry jam on top, and layer with another quarter of dough. Repeat until all the jam is incorporated into dough layers. Fold and swirl lightly without fully mixing in the jam.

Place cookies on parchment-lined baking sheets, spacing adequately. Bake in batches of six for 11-12 minutes. Optionally, use a circular cookie cutter to shape cookies immediately after baking. Cool on the baking sheet for 10 minutes, then transfer to a wire rack to cool completely.
