As a child, I was utterly fascinated by science. That is, when I wasn’t drawing , baking with my nan or building abstract structures with blocks of wood from my Dad’s offcuts bucket in the garage. On days when my bookshelf sang it’s siren song to me, I would frequently be found with my nose firmly wedged in my Usborne Encyclopedia of Science reading over and over again all about what the world around us was made up of and how it functioned. I’d marvel at the odd luminescent creatures that lived only in the depths of the Marianna Trench and was utterly captivated by those giant prehistoric lizards-cum-birds, the dinosaurs. The chapters on space were filled with pretty drawings of the planets and it tried to explain the incomprehensible vastness of space to this starstruck, mouth opened, eyes wide little tot. I still stare up at the night sky with fascination at the stars twinkles millions of light years away and now, we can all get a little bit of that celestial wonder in the form of my Galaxy Glazed Millionaire’s Slice

What we have here is a take on millionaire’s shortbread. To make it a little easier, this slice is made with a crushed biscuit base like you would do for cheesecake (I think Custard Creams are the best biscuit but you could use Shorties or a similar brand of shortbread biscuit instead). The caramel layer is one I’ve worked on for years and go back to with confidence tie and time again – it always sets well. It is sliceable but still softly set, no fillings will be pulled out by this treat! As it’s almost Christmas (and I think it works better anyway) I poured a layer of dark chocolate ganache over the caramel. I always use Callebaut dark callet for all my dark chocolate needs – it’s 55% and even dark chocolate loathing Hungry Hubby loves this particular one. To finish the slice, I top it with a set glossy glazed swirled with bright wisps of colour depicting cosmic dust and sprinkled with edible purple and gold glitter to depict all those twinkly stars. Watch this brief video showing you just how easy it is to get a galaxy glaze finish:

See – super easy! And it really is delicious to eat too – I spent a lot of time trying different ideas I had for the glaze and this is the best (and luckily the easiest one) to make! The craze for galaxy glazed confections started with donuts that you dip into a bowl of glaze with the colours already swirled into it. If I’m honest, the illusion of a whirling vortex of stars around the perimeter of a Black Hole are a little better for the dipping, pouring it over a Millionaire’s slice is not too shabby a way of creating a similar effect. I’m still working (painfully) hard on my donut recipe so there may well be more galaxy glazes coming your way soon! For now, I hope you enjoy my Galaxy Glazed Millionaire’s Slice – I think it is a perfect sweet treat for the festive season as you can slice it into long bars for an out-of-this-world dinner party dessert, or chop it up into little chunks for bite sized sweet treats.

Galaxy Glazed Millionaire's Slice
Serves 10
A Millionaire's shortbread taken out of this world by a glossy Galaxy Glaze on top of the luxurious chocolate ganache.
Print
For the base
  1. 200g custard creams
  2. 50g melted butter
For the caramel layer
  1. 200g condensed milk
  2. 40g soft light brown sugar
  3. 1 tbsp golden syrup
  4. 50g soft butter
  5. 1 tsp vanilla extract
For the chocolate ganache
  1. 200g dark chocolate
  2. 100g double cream
For the Galaxy Glaze
  1. 2 tsp powdered gelatine dissolved in 40ml water
  2. 40g double cream
  3. 30g caster sugar
  4. 30g golden syrup
  5. 50g white chocolate
  6. Black, purple, blue, pink and yellow food colouring gels*
  7. Gold and Purple edible glitter (Disco Dust)
Equipment
  1. Removable bottom tart tin (35x12cm) or foil tray (I've used 7x5 inches to good effect)
  2. 6 small bowls
  3. A whisk
  4. A palette knife
  5. A pastry brush
  6. A cocktail stick or skewer
  7. Flat bladed/ dinner knife
Instructions
  1. You can either a removable base rectangular tart tin as per the blog post or I have made this in a 7x5 inch disposable foil brownie/fudge pan.
  2. Make the base by blitzing the biscuits in a food processor until a fine crumb is achieved (check for big lumps) then with the motor running, pour in the melted butter and stop once well mixed. Tip into your tart tin/foil tray and press down really firmly (use a glass or measuring cup with a flat bottom). Pop in the fridge whilst you make the caramel.
  3. Put everything for the caramel layer in a medium sauce pan and stirring constantly, cook over medium heat until it has turned a few shades darker - you are looking for the brown of a manila envelope or slightly darker. You must stir constantly or it will definitely burn!
  4. Quickly and carefully pour all the caramel over the biscuit base and if necessary, use a palette knife run under hot water to smooth. If you work quick enough, it wont be necessary as it will find it's own level.
  5. Leave to cool completely before making the ganache - don't put it in the fridge though, leave at room temp so the caramel doesn't sweat.
  6. When cold, make the ganache by heating the cream to the boiling point in a medium saucepan and then stir in the chocolate - I use callets (chips) but you'd need to chop a bar up into small pieces to get it to melt quick enough. Beat well with a spatula so there are no streaks remaining then pour over the set caramel. Again use a hot palette knife if necessary to smoothen it off but you really don't need to be too precious about it here.
  7. Once cold, make the glaze - it is very worth getting all the ingredients and kit you need ready before you start so you don't have to stop to get what you need before the glaze sets.
  8. Stir the gelatine and 40mls water together in one of the small bowls and allow to sit. Pour the cream, caster sugar and golden syrup into a small saucepan and bring up to a rolling boil, stirring regularly to ensure it doesn't catch and burn.
  9. Take off the heat, whisk in the bloomed gelatine and when smooth, tip in the white chocolate and whisk until no streaks remain. Pour about half of it into one bowl and add a few drops of black food colouring to this one - stir well. Divide the rest between the remaining four bowls and add a little food colouring to each, again mixing each well (I use one teaspoon per bowl).
  10. Now, take your tart and pour over the black glaze. Immediately, drizzle over the other colours one at a time, swirling them haphazardly - watch the video to see how I do it. Use a cocktail stick or flat bladed dinner knife to swirl so you have thin wisps of colour, like streaks of colour in a depiction of the Milky Way and Galaxies! Work promptly but don't go crazy - the gelatine will set within an hour but if you do find any of the glazes are setting too quickly, rewarm over a Bain Marie or give 15 seconds blasts in the microwave.
  11. Before set, dip your pastry brush in the purple Disco Dust and flick all over the surface of the tart (again the video helps here). Finally, dip the pastry brush in the gold Disco Dust and flick in just a few places to give a nice cluster of bright shiny stars in the night sky you have just created.
  12. Leave at room temp to set before slicing - you can pop it in the fridge if it very warm where you live to no ill effect.
Notes
  1. *= I use Sugarflair food colouring gels for everything apart from the black one - I like PME black liquid food colouring here.
