Combine the flour, sugar, baking powder, and salt in a medium bowl and mix well. Cut in butter with a pastry blender or fork until crumbly. Add egg and milk and stir until just moistened.
Spread in a well greased 9x9 baking dish. Spread both preserves over top using a knife to swirl the preserves through the batter. Don't swirl too much ~ you want to be able to see some swirls. Sprinkle evenly with the topping.
Bake at 400º for 25-35 minutes. Use a toothpick to check for doneness.
Topping: In a small bowl, mix all ingredients with a fork until crumbled.
