RECIPE NOTES & TIPS
I like to use Arnott's Butternut Snap's for the biscuit base, as the butternut flavour compliments the raspberries well, however any crunchy plain, coconut or chocolate biscuit could be used if you cannot find Butternut Snaps.
Use room temperature ingredients (butter and eggs) as this helps the ingredients to blend easier and allows the baking process to start straight away when placed in the oven.
If your tart is browning too much on top, loosely cover tart with a piece of foil and continue baking.
Storing - store covered, in the fridge for up to 3 days.
Freezing - raspberry frangipane tart also freezes well, however I recommend it be frozen for no more than 6 weeks otherwise it loses some of the delicate flavours. Allow to thaw completely in the refrigerator before serving either cold, or slightly warmed.
