A crisp almond flour crust forms the base here, pressed firm and baked until golden before it's topped with a silky lemon filling made from fresh lemon juice, plenty of zest, and whole eggs whisked smooth with tapioca starch. That starch does double duty, setting the filling into a clean, sliceable layer with just the faintest wobble when it comes out of the oven. A long chill in the fridge is what gives these bars their signature dense, custardy texture and lets you cut them into neat, tidy squares. The bright citrus punch balances beautifully against the nutty, buttery crust underneath, so every bite has that classic sweet-tart lemon bar contrast. It's an easy make-ahead treat to slice and share, and it fits neatly into an added sugar free spread without missing a beat.

Preheat the oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving a 2-inch overhang on two opposite sides to use as handles for lifting.
In a medium bowl, whisk together the almond flour, tapioca starch, powdered sugar, and salt until evenly combined. Pour in the melted butter and stir with a rubber spatula until the mixture clumps together and holds its shape when pressed.
