“I wish I could bake” is one comment I here a lot from people!

I always tell them “ yes you can” –  just start off with something simple like muffins or fairy cakes or even this very simple Custard Cream Sponge Tray-Bake.

It’s a quick very simple recipe and  I’m sure everybody could bake it, even a complete beginner at baking.

This recipe which I got from my Mum is an all-in-one recipe, which means its mixed in one bowl.   My Mum was famous for her tray-bakes especially when it came to school bake sales.  She used a very simple sponge recipe but added great flavours to make them a bit special.  Everybody was crazy for her Chocolate Knickerbocker Glory tray-bake.  I promise I’ll share that recipe one day, but to-day Its my Custard Cream Tray-Bake.

Custard creams biscuits are the cheap and cheerful of the supermarket biscuits!  You can get a packet in any supermarket for around 50c sometimes cheaper.  When I was young they were a very posh biscuit and could be only found in the special tin of biscuits that you could only buy at Christmas.  My brother’s and I had many fights on Christmas day over those biscuits. There was always only 3 custard creams in the tin and there was 4 of us.

Speaking of Christmas last week my local supermarket had it’s Christmas tins of biscuits on the shelves along with tubs of Cadbury Rose’s Chocolates and it’s not even Halloween yet.



Back to the recipe. I was going to make an apple sponge tray-bake, but that went out the window when I saw my oldest and his friends chomping down the last of the apples.  I made myself a cuppa and  grabbed two sneaky custard creams to dunk and bingo “light bulb” moment, why not use the custard creams  in the sponge tray-bake.

I whisked together the very easy sponge recipe, broke the biscuits into small pieces and just folded these into the batter. Pour the batter into the baking tin , dollop spoonfuls of custard on top and bake for 30 mins.

It might be cheap and cheerful l but I promise you this Custard Cream Tray-Bake makes a delicious dessert especially with some extra warm custard poured on top.

If my American or Australian friends find it hard to get these biscuits, then try substituting with Golden Oreos!!!

    Hi Karyn, Thanks for all your lovely recipes. Love your blog especially with the great photos. Just a clarification on this recipe – the butter measurement – is it really only 75 gms? Thought I would check before I attempt to make it. Regards, Jackie

    • Karyn September 7, 2017 at 7:38 am

      Hey Jackie😁 thanks a million for spotting that the correct amount is 175g. Have changed it now phew! appreciate you letting me know x

  • Joanna @ Everyday Made Fresh September 8, 2017 at 1:40 pm

    This looks extremely decadent. I’m not sure if it’s because of the custard cream or what, but I’d love to have one of those squares.

    • Karyn September 10, 2017 at 8:11 pm

  • Jodi @ Create Kids Club September 9, 2017 at 6:04 pm

    I am not much of a baker, but you make it sound so easy! And I love the converter at the bottom, I am not great at doing that math on my own! 😉

    • Karyn September 10, 2017 at 8:14 pm

  • Nadja | Nashi Food September 9, 2017 at 8:52 pm

    • Karyn September 10, 2017 at 8:08 pm

      Thank’s Venna 😉 my kids love it too

  • Marisa Franca @ All Our Way September 10, 2017 at 7:21 pm

    What a great recipe. It certainly looks easy and there are so many variations you can make. I believe that if people take a little time they can bake. It’s not difficult — it’s a matter of following directions. Your mum must have made lots of tray bakes — they sound delicious.

    • Karyn September 10, 2017 at 8:07 pm

      She did Marisa lol ; She was always experimenting, still does 😉

  • Dene' Alexander September 10, 2017 at 10:28 pm

    This looks absolutely divine! Between the lemon curd, the biscuits and the sponge cake, I have no idea where to start!! Yummmmm-e

    • Karyn September 11, 2017 at 3:00 pm

      It’s one of those addictive cakes lol one square is never enough Dene x

  • Christine - Jar Of Lemons September 10, 2017 at 10:35 pm

    This looks and sounds AMAZING! Yum!

    • Karyn September 11, 2017 at 2:59 pm

      Thanks Christine.. the simple things are always the best

  • Ashley - Forking Up September 11, 2017 at 12:06 am

    I’ve never had a custard creme biscuit, but I love sponge and I love custard sooo… I think I’d love this!

    • Karyn September 11, 2017 at 2:58 pm

      You really would Ashley especially if you like could try using golden oreos if you have trouble getting custard creams

  • Teri September 11, 2017 at 12:37 am

    My favorite part about this recipe is it looks so moist and yummy. I think I will show this recipe to my daughter, a great thing for her to try her hand at. (She 11 and will love this.)

    • Karyn September 11, 2017 at 2:56 pm

      Absolutely Teri It’s a great one for kids to try their hands at..It’s brilliant that you daughter likes to bake especially at a young age x

  • Kylee from Kylee Cooks September 11, 2017 at 3:36 am

    I LOVE me some custard creams. I can’t say “no custard creams were harmed during the making of this dessert” because I’d have to buy 2 packs – one to snack on while making – and one to use for the recipe!! yum!!

    • Karyn September 11, 2017 at 2:57 pm

      Me too Kylee.. I always have a sneaky one or two while I’m baking. I have no will power

  • Catherine September 11, 2017 at 2:06 pm

    This looks absolutely fabulous!! Saving this recipe for a later date…I’ve never made a custard cake but I’d love to give this one a try!

    • Karyn September 11, 2017 at 2:55 pm

  • Swathi September 11, 2017 at 5:53 pm

  • Andrea September 12, 2017 at 8:51 pm
