Preheat your oven to 350°F and line a small loaf pan with parchment paper to prevent sticking.
In a medium bowl, stir together the almond flour, melted coconut oil, and sea salt until the mixture resembles wet sand.
Press the almond dough firmly into the bottom of the prepared pan and bake for 10 minutes until the edges are lightly golden.
While the crust bakes, place the silken tofu, egg whites, maple syrup, lemon zest, lemon juice, and vanilla extract into a high-speed blender.
Blend on high until the filling is completely smooth and creamy with no visible tofu particles.
Pour the silken lemon mixture over the warm crust and scatter the fresh blueberries evenly across the top.
Bake for 35 to 40 minutes until the edges are set and the center has a slight, firm jiggle.
Remove from the oven and allow the bars to cool to room temperature, then refrigerate for at least 3 hours to ensure clean, firm slices.
