Instructions
Preheat oven to 350°F (175°C). Line a 9×13-inch pan with parchment, leaving overhang, and spray lightly.
Cream butter and sugar until light and fluffy, about 2–3 minutes.
Add egg, vanilla, and almond extracts; mix until smooth. Whisk dry ingredients separately, then combine into a soft dough.
Press 2/3 of dough into the prepared pan for the crust. Bake 12–15 minutes until lightly golden.
Loosen jam, stir in lemon zest if using, warm briefly if needed, then spread over the crust. Crumble remaining dough on top and sprinkle with sliced almonds.
Bake 25–30 minutes until golden and bubbly. Cool completely, then lift from pan and cut into 24 bars.
Notes
Chill bars before cutting for cleaner slices and better setting.
