Speculoos marble cake with speculoos streusel

First off, let me just say that I LOVE speculoos! But it is really a guilty treat for me, as I do try and avoid super-sugary spreads like this. But it is just so good! Great on toast, as a dip for fruit sticks, or – my favourite late night indulgence – spread it onto a plain biscuit and top with melted chocolate. YUM! Instant, gooey, millionaire’s shortbread. You can thank me later.

Speculoos aka biscoff aka Lotus caramelised biscuit spread aka cookie butter is one of those spreads, like Nutella, that can do so much more than tart up a slice of toast or a sandwich. The Internet abounds with recipes that use Nutella (including several of mine!), and speculoos/biscoff/cookie butter as an ingredient is rapidly catching up. It’s even been made into speculoos hamantaschen!

I decided to use it to make a moist and delicious swirl for my marble cake, and then in a moment of craziness, I added a layer of speculoos crumble to the top for good measure. The finished cake looked fab under its streusel topping (and no need to mess about with frosting – hurrah!) and was get-in-my-face fantastic! We ate it after Shabbat lunch with some fruit salad and ice-cream and it was gorgeous! It also goes brilliantly well with a nice cup of tea 🙂

A moist, delicious marble cake, swirled with cookie butter & topped with a gorgeous crumble of speculoos crumbs, oats & nuts. Lovely served cold, wonderful warm as a pudding with cream, custard or ice-cream.

Later on, I briefly microwaved a slice of the leftover cake and ate it with a dollop of natural yogurt – terrific! So I can personally vouch that this cake works well as a pudding too – simply warm gently (or serve it still warm from the oven) and accompany with ice-cream, custard, cream or yogurt, then sit back and listen to the compliments come rolling in…

This makes one 21cm square cake, which can be cut into 9-16 squares, depending on how generous you’re feeling! Go on – indulge!

For the streusel topping
  1. 1 tbsp speculoos spread

  2. Sprinkle the streusel topping over the cake to give an even layer.
  1. Bake at 180C for 25-30 minutes until golden and a toothpick inserted into the centre of the cake comes out clean.

I’m joining this recipe in with a few foodie link-ups and challenges. Firstly, Cook Once Eat Twice hosted by Searching for Spice, since we enjoyed this first as a cake, and then later on warm as a pudding. The No Waste Food Challenge hosted by Elizabeth’s Kitchen Diary, since I used up the end of a jar of speculoos making this cake. The Food Year Link-Up, hosted by Charlotte’s Lively Kitchen, as this would be a fab treat for Mums on Mothers’ Day (or any time!). And finally CookBlogShare hosted by Snap Happy Bakes.

  3. Wow this sounds delicious – and thank you for finally explaining to me what speculoos is, I’ve been meaning to google it for ages as I keep seeing it everywhere but you’ve saved me a job!

  4. Oooh yes! You’ve outdone yourself Helen!

  5. I have never tried speculoos but I love the sound of it. In fact, I think I’m afraid if I do try it I’ll eat way way too much! Thank you so much for joining in with #CookOnceEatTwice.

    • Thanks Corina. It’s a bit like Nutella in that respect. I may once have eaten it straight from the jar with a spoon. Only once though… honest.

    Oh wow this sounds amazing. I could do with a slice now 🙂 Thanks for linking up to #CookBlogShare

  7. Oh, I know just what you mean. Not a single good ingredient included, but it tastes so good. I love the consistency too. Lovely idea to swirl it through a cake.

  8. Oh my goodness, what have you done to me??! I’ve never tried Speculoos, and had to go google it – I assumed it would have dairy in, but it turns out it doesn;t and now I have to hunt down a jar and try it 😀
    You are fully to blame for my latest addiction Helen!
