    This recipe is on my ‘to try’ list, but have a question on the pastry.
    Which brand of Puff Pastry is vegan ?

    • Nikki December 2, 2014 at 6:50 am #

      Hi Sylvie,
      I use “Borgs” puff pastry. It even has ‘vegan’ written on the front of the packet.
      Enjoy 🙂

    Hi Nikki, what custard powder do you use for this lovely recipe! 🙂 Thanks

    • Nikki January 11, 2015 at 7:38 am #

      Hi Ollie,
      I use the ‘orgran’ brand. Just my preference 🙂

    I love how simple all your recipes are. Can I ask what brand pastry and custard powder you use and where you get vegan versions of these?
    Also what vegan margarine do you use, as the usual stuff in the super markets all have dairy in it. Nuttalex doesn’t have dairy but only their Sunburst version has no palm oil in it. The rest do and I think it’s coconut based. Is this okay to use?

    • Nikki April 17, 2015 at 7:21 am #

      Hi Kristy,
      Thanks for dropping me a line 🙂
      I use “Borgs” pastry & I find it is available in most supermarkets in the freezer section. It even has vegan written on it 🙂
      The custard powder I prefer is “Orgran”. Again I find it at most supermarkets in the health food or gluten free section. Plus our local health food store.
      Sunburst is fine to use! I believe the olive nuttalex doesn’t have palm oil in it……but I could be wrong as companies like to change their ingredients around to keep us on our toes.
      Enjoy the vanilla slice & WOW your pre-vegan family & friends.
      Stay kind xx

    I love this slice!
    Today I tried it with almond milk, and it turned out a little bit sweet for my taste. Checked the ingredients on the almond milk and it contained sugar. D’oh!

    • Nikki June 29, 2015 at 1:21 pm #

      Glad you liked it Emma & thanks for the feedback. I know when I make my own soy milk it needs sugar…otherwise it’s pretty rank haha
      I’ve never made vanilla slice with oat milk but thought I’d share this with you: (maybe omit the maple syrup?)

      Oat Milk

      1 cup of rolled oats
      3 cups water
      1.5 – 2 tablespoons maple syrup
      1 teaspoon vanilla essence
      ¼ teaspoon of salt
      ¼ teaspoon cinnamon

      1. Soak your oats for at least 30 minutes. Overnight is fine
      2. Drain & rinse oats well
      3. Place oats in blender with water
      4. Blend on low for 20 seconds & on high for 10 seconds
      5. Place a fine sieve over a large bowl/jug & pour contents through. Use a spoon to move the pulp around to ensure all liquid makes it into the jug
      6. Clean out sieve & blender, place sieve over the top of blender & pour contents back in
      7. Add maple syrup, vanilla essence, salt & cinnamon & blend to combine
      8. Pour into a clean bottle & keep in fridge for 4-5 days

    does this recipe freeze?

    • Nikki October 26, 2015 at 2:36 pm #

      Hi Joan,
      I’ve never frozen vanilla slice ever so honestly couldn’t tell you. Perhaps if you discover the answer you can let me know.
      I’d be prone to think they wouldn’t but who knows. They don’t last long enough around here to find out.

    • Nikki December 22, 2015 at 6:39 pm #

      That’s a record Kara! Enjoy 🙂

    Made this yesterday. It is so good, but i think i would have liked it a tad sweeter so will use maybe almond milk next time. Thanks, another great recipe! x

    • Nikki January 11, 2016 at 9:52 am #

      I like the idea of the almond milk. Very nice 🙂
      Thanks for your feedback Angela 🙂

  11. Ruth February 28, 2016 at 5:54 pm #

    Is it okay to use coconut spread?

    • Nikki February 29, 2016 at 7:20 am #

      I can’t see why not Ruth. Give it a go & maybe report back to let others know how you went.
      Nikki 🙂

  12. Sandy May 17, 2017 at 3:44 pm #

    i dont have egg free custard powder… any alternatives?

    • Nikki May 23, 2017 at 2:06 pm #

      Hi Sandy,
      Sorry about the delay – you could sub with cornflour & add a little extra vanilla essence.

  13. Wendy March 29, 2019 at 8:16 am #

    OH MY GAWD Nikki this is the BEST Vanilla Slice I have had!

    • Nikki March 29, 2019 at 4:43 pm #

      I’d say ‘enjoy in moderation’ but we know how hard that is don’t we?

  15. Zoe October 28, 2019 at 4:37 am #

    I have been using this recipe for years now! Friends and family are always asking me to make it – sooo tasty especially with passion fruit.

    • Nikki October 28, 2019 at 5:31 am #

      That’s awesome Zoe! Do they know it’s vegan? 😀

      • Zoe October 29, 2019 at 6:56 pm #

        They do, but don’t notice a difference between this and a non-vegan version 😍

    • Nikki October 30, 2019 at 9:16 am #

      I love it!! 😀

  16. Joanna November 19, 2019 at 5:58 pm #

    Recipe looks great, I’m keen to try it out!
    I make it Just about the same way, except I don’t add margarine – can I ask what it does?

    Thank you

    • Nikki November 20, 2019 at 10:30 am #

      It just makes it a little creamier Joanna 🙂

      • Joanna November 21, 2019 at 6:15 pm #

        Thanks so much, I’ll try yours next time!
