01 - Preheat oven to 350°F. Line an 8-inch square baking pan with parchment paper, allowing overhang for easy removal of bars.
02 - Whisk together flour, matcha powder, powdered sugar, and salt in a bowl. Cut in cold butter until mixture resembles coarse crumbs. Press evenly into the pan bottom. Bake for 12–15 minutes until just set. Let cool slightly.
03 - Combine strawberries, sugar, and lemon juice in a small saucepan. Cook over medium heat, stirring and mashing, until strawberries break down and mixture thickens, about 8–10 minutes. Cool slightly, then purée with a blender or mash until completely smooth.
04 - Beat cream cheese until smooth and creamy. Add condensed milk, egg, and vanilla extract; mix until fully incorporated and silky in texture.
05 - Pour the cream mixture evenly over the cooled matcha base. Drop spoonfuls of strawberry purée across the surface. Gently drag a knife or skewer through the fillings to create a marbled swirl pattern.
06 - Bake for 20–25 minutes until the center is just set and edges are lightly golden. Cool completely to room temperature, then refrigerate for at least 2 hours before slicing into clean bars.
