Biscoff Caramel Slice Thermomix

Biscoff Caramel slice is another way to enjoy the uniquely flavoured, spiced Biscoff cookie in a dessert-style treat. This layered slice starts with a Biscoff biscuit crumb base, a layer of rich baked caramel, and a thin chocolate layer that holds the Biscoff crumb topping in place.

This is a three-layer slice but it's super simple to make and can be easily prepared on the stove-top if you don't have a Thermomix. I will directions for both methods below. Making the caramel filling in the Thermomix feels like cheating as you just add the ingredients and walk away. It's a completely "hands-free" layer!

The Biscoff Caramel Slice Story

The other day I needed a coffee whilst I was out and about near Terrigal. Happily, I spotted a car park right out the front of a cafe called Sal & Co. If you know the area you would know that a carpark is GOLD, it means the Gods are smiling. I nabbed the park and went inside to order. The aroma of coffee was music to my nose. As I waited in line I noticed a ver enticing cake display.

I knew it was a mistake to look at the array of slices, cakes, cheesecakes, and more, but I couldn't help it. Before I knew it I was choosing between a mini Lemon Meringue Pie and a Biscoff Caramel Slice. I ordered the Biscoff Slice with my coffee and hurried to the car.

After craving a coffee all morning I had barely a mouthful before I took a generous bite of the slice. Oh, Dear!! It was so much better and sweeter and more delicious than I imagined it would be. I knew I was in trouble! This cafe was WAY too close to home!

As I savoured every bite I analysed the layers. It was a really simple slice but it certainly added up to more than the sum of its layers.

At that point, I decided I would make my own Biscoff Slice. Of course, that meant going back a few more times to the Sal & Co cafe... for quality control purposes of course.

Biscoff Slice Ingredients and Substitutes

When I was testing the recipe I had trouble finding Biscoff Biscuits, so I first made the slice with Speculaa biscuits. Speculaa's are a Dutch spiced cookie that is sometimes found in the international section of the supermarket. I also found a version in Aldi!

Speculaa V's Biscoff

Speculaa's and Biscoff are different biscuits but they both have a rich dark caramel flavour. The Speculaa's add a hint of cinnamon, cloves, cardamom, and ginger to the base and crumb.

The Biscoff has a more caramelised crispy, toffee sugar taste. The crumb topping is slightly darker and sweeter.

The results were fabulous with either brand of cookie. If you have trouble finding the cookie of your choice, feel free to substitute it with the other. I had more luck in Aldi and Coles. I have a feeling Woolworths have discontinued both.
