Preheat your oven to 350°F and line a small loaf pan with parchment paper for easy removal.
Combine the almond flour, melted coconut oil, and sea salt in a bowl until a crumbly dough forms.
Press the dough firmly into the bottom of the prepared pan and bake for 8 minutes until the edges are lightly golden.
Place the firm tofu, egg whites, maple syrup, lemon zest, lemon juice, and vanilla extract into a high-speed blender.
Process the mixture until it is completely smooth and velvety, ensuring no tofu lumps remain.
Pour the lemon filling over the warm crust and scatter the fresh blueberries evenly across the top.
Bake for 30 to 35 minutes until the edges are set and the center has a slight, firm jiggle.
Allow the bars to cool at room temperature, then refrigerate for at least 2 hours to achieve a clean slice.
