Preheat oven to 400°F. Spray an 8 inch square baking pan with non-stick cooking spray.
In a medium bowl, combine the flour, baking powder, salt and sugar. Add butter, egg, milk and vanilla, almond extract and lemon extract. Mix until just combined.
Pour about half of batter into prepared pan, spreading evenly. Stir the preserves and spread it evenly over batter. Top with remaining batter, again spreading evenly.*
In a small bowl, combine topping ingredients; mix until crumbly. Sprinkle over top of the batter.
Bake in preheated oven for 20 to 25 minutes or until a toothpick inserted in the center comes out clean or with dry crumbs.
