Millionaire's Shortbread - these delicious Millionaire's Shortbread squares have all the delicious taste of their regular version, but are slightly lower in sugar and calories.

Caramel Chocolate Shortbread
If you love twix bars, then you will just love these, biscuity crumb base topped with toffee and milk chocolate what more could one ask for.
I've had this idea in my head for a while. The toffee and the chocolate was easy, but coming up with a biscuity base was the test. But I am not one to be defeated and after a few experiments with different mixes, I am really happy with the results of these.
Best Natural Sweetener
To reduce the amount of sugar in these Millionaire's Shortbread I use a naturally derived sweetener call Erythritol. I have tested many different types over the years and this is the closest in taste to normal sugar.
Can I use any granulated sweetener?
I will only use the sweetener as mentioned above, so haven't tested these out with any others, so can't say how well they will turn out or taste.
There are a couple of things to bear in mind when using different types and that is that not all granulated sweeteners are equal. Erythritol is generally used in the same quantity as sugar, other sweeteners you may need to more or less. So I always advise checking the label of the one you use as it will tell you the ratio to sugar and you can therefore adjust correctly.
Can I use low fat margarine?
I use real butter as it is all I buy in my house, we as a family do not like margarine or low fat spreads. For this reason the shortbread has not been tested using a margarine.
You would have to try it yourself if you want to try and reduce the calories a little more.

Can I use light evaporated milk?
Light evaporated milk doesn't yield as good a caramel, so I would definitely stick to the original kind for this to ensure it yields a nice creamy caramel.
Can you freeze evaporated milk?
This gets mixed answers, while you can freeze it, it can seperate onced thawed so is not suitable for some recipes.
If you are wondering what you can do with the remainder, you could make a double or triple batch of the caramel sauce, this is great for drizzle on low calorie icecream or for serving with some sliced apple.
Another way I like to use it, is by adding a little to this Creamy Rice Pudding to make it extra creamy or add a little bit to this Quick Mac and Cheese is delicious too. You can actually add it to anything to add a little bit of creaminess, so things like soups are good too.
Can I use all Sweetener in the Caramel?
I don't recommend using just sweetener in the caramel, it needs some sugar to ensure it caramelizes and the demerara sugar really adds to the flavour.

What size baking tin for Millionaire's Shortbread?
I use an 8inch square brownie pan lined with some parchment paper to baking the shortbread base. You don't really want to use any bigger that this as the shortbread mix won't be enough to cover the base.
Can Millionaire's Shortbread be frozen?
If you are worried about the temptation of eating more than you should, then I recommend freezing these in a container. You can then just take one or two out as you want them and defrost before enjoying. A yummy sweet treat with a cuppa.

Hi Siobhan,
I was just wondering if I might be able to substitute the plain flour for coconut flour?
Many thanks, Rhiannon
Katie says
Hi I have a large tub of sweetener which is 75 grams, so is it the whole tub plus a little more?? It seems too much so I wanted to check! Thank you
Siobhan (Slimming Eats) says
certain sweeteners are not equal to each other, Sukrin is used like for like for sugar, other sweeteners are not, you would need to check the tub of the sweetener you have for the sugar to sweetener ratio.
