Custard Slices

I am starting to think I should have called my book – All of Mandy’s Favourites.  Custard Slices are one of those yummy treats that I love seeing on the table at tea parties, next to the quiche, you know, just to balance the sweet and savoury taste buds in one go along with the ever important cup of tea.

  1. My mother used to make a similar custard slice when I was a kid – only much more basic. Just Sao crackers (a plain, dry cracker available here in Australia), custard made from straight custard powder and lemon or passionfruit icing. This looks to be much more the thing with the added eggs and butter!

  2. YUMM!! Now I have something ELSE to bake today……I’m already in the kitchen baking birthday cakes and some other stuff so why not add this deliciosity to my retinue today?? Have not made these in years. Thank you for the fabulous memory jog!! MWAH! xx

  3. I kinda disagree with you, if I’d see a custard slice near a quiche I’m 110% sure the custard would disappear faster :))
    Your slice look stunning, thanks for sharing.
    Have a wonderful weekend

  4. Mandy, this looks so rich and creamy. I’ve never had a “real” custard like this. Is it similar to a bread pudding? Sounds delicious.
