Ingredients

Here’s everything you should know about the ingredients needed to make Halloween millionaire brownies.

Brownie

• Unsalted Butter – Unsalted butter is best here as it gives you full control over the salt content. It doesn’t matter if it’s straight out the fridge as you will be melting it anyway.
• Dark Chocolate – Don’t sub this for milk chocolate or your brownies will be too sweet! Use a good quality dark chocolate if you can afford it as you will taste this in the end result.
• Eggs – Free range organic are my go to but any you have will work. A medium size is perfect.
• Golden Caster Sugar – I like to use golden caster sugar as it gives a slight caramel flavour. Regular white caster sugar (superfine in the US) will work great too though.
• Vanilla Extract – Always use a good quality vanilla, you really do taste the difference!! My favourite is Nielsen Massey (affiliate link) as it gives a wonderfully strong vanilla flavour.
• Salt – Salt is salt. Table salt will work fine! No need to get fancy here.
• Plain Flour – Plain flour (all purpose in the US) is ideal for this. Don’t sub for self raising as we want gooey brownies not cakey ones!
• Cocoa Powder – Make sure you use baking cocoa powder and NOT drinking chocolate as that already has added sugars.

Caramel

• Condensed Milk – Sweetened condensed milk here please! The brand doesn’t matter, all kinds I’ve tried have worked just fine.
• Unsalted Butter – As said above, using unsalted gives you control over the salt content. It’s a no brainer.
• Golden Caster Sugar – See above.
• Golden Syrup – Golden syrup gives a unique and wonderful flavour to your caramel. You can use corn syrup in the US but it won’t taste the same.
• Vanilla Extract – As mentioned before, use a good quality vanilla as you will taste the difference!
• Salt – Again, table salt is fine here. No need for fancy sea salts or anything.

Topping

• White Chocolate – You can get away with using a cheaper brand of white chocolate here if you wanted to. A good quality brand will obviously taste a little nicer, but no one will notice if you don’t as there’s a lot going on in the 3 layers!
• Red Food Colouring – This is important. Use an extra strong food colouring gel like this sugar flair one (affiliate link). Liquids will change the consistency too much and regular strength gels won’t give you a dark enough colour.
• Edible Eyes – You can usually buy these in most supermarkets around Halloween. Failing that, you can easily buy them off Amazon or eBay.

Recipe tips

Here are some tips I think you will find helpful when making this recipe. I make the mistakes so you don’t have to!

• Use actual baking measuring spoons (affiliate link). The teaspoon you use to make your cuppa is not the same!!
• Allow the brownie to cool COMPLETELY before continuing with the recipe. Trapped heat can effect the consistency of the caramel in a negative way.
• When making the caramel, use a thermometer to take out any guess work. It makes is SO much easier!
• Ensure you stir the caramel constantly, getting right into the edges of the pan. Otherwise your caramel might burn and you’ll get horrible dark bits floating through it.
• Do NOT use liquid food colouring when making the chocolate topping. It will affect the consistency too much. Instead use an extra strong red food colouring gel like this sugar flair one (affiliate link). It won’t affect the consistency and will give you a lovely deep red colour.
• Don’t heat the white chocolate/red colouring gel for longer than 10 seconds at a time. The colouring gel could burn and the white chocolate could overheat, leading to unsightly ‘bloomed’ chocolate.
• It’s important to melt the white chocolate with the food colouring. If you add it after – the chocolate could seize due to the temperature difference.
• Decorate each bar one at a time. This will prevent the chocolate from setting too quickly ensuring you can still push the edible eyes into the top.

(For a printer friendly version, see the recipe card at the end of this post)

Ingredients

Here is what you will need to make 16 bars.

Brownie

• 110g (1/2 Cup) Unsalted Butter, cubed
• 110g (3.9 oz) Dark Chocolate
• 2 Eggs
• 225g (1 + 1/8 Cup) Golden Caster Sugar
• 1 tsp Vanilla Extract
• 1/4 tsp Salt
• 60g (1/2 Cup) Plain Flour
• 2 tbsp Cocoa Powder

Caramel

• 200g (2/3 cup) Condensed Milk
• 125g (1/2 cup) Unsalted Butter, cubed
• 125g (2/3 cup) Golden Caster Sugar
• 2 tbsp Golden Syrup
• 1 tsp Vanilla Extract
• Pinch Salt

Topping

• 200g (7oz) White Chocolate
• 1 tsp Red Food Colouring Gel *
• 32 x Edible Eyes

*I used Sugar Flair Extra Strong Red Food Colouring Gel (affiliate link)

Essential equipment

• 20cm (8″) Square Baking Tin
• Large Microwavable Bowl
• Medium Saucepan
• Sugar Thermometer (Optional but recommended)

Brownie instructions

Firstly, grease and line your baking tin and preheat the oven to 180°C/Fan 170°C/356ºF.

Then put the unsalted butter (110g | 1/2 Cup) into a microwavable bowl and break in the dark chocolate (110g | 3.9 oz). Heat in the microwave in 10 second intervals, stirring well after each time.

Once it’s two thirds melted, stir the rest of the way until completely melted.

Next add in the eggs (x2) one at a time, beating well after each one.

Now add in the sugar (225g | 1 + 1/8 Cup) and beat thoroughly until it no longer feels grainy on the bottom of the bowl anymore.

Time to add in the vanilla (1 tsp) and salt (1/4 tsp) and give it a brief stir.

Finally, fold through the plain flour (60g | 1/2 Cup) and cocoa powder (2 tbsp) and fold gently, just until you can no longer see any streaks left in the batter.

Smooth the batter into your prepared tin. Oh the pegs? Yeah – I’m a very lazy liner, hahaha!

Bake in the preheated oven for 21-25 mins until the top is crispy on top.

Leave in the tin and allow to cool completely before moving on to the next step.

Caramel instructions

Place all the caramel ingredients into a medium saucepan and set over a low-ish heat. (200g | 2/3 cup condensed milk, 125g | 1/2 cup unsalted butter, 125g | 2/3 cup golden caster sugar, 2 tbsp golden syrup, 1 tsp vanilla extract, pinch of salt).

Bring to the boil, stirring constantly. This is important – you need to stir all the time, right into the edges of the pan, to ensure your caramel doesn’t burn.

Once boiling, simmer (still stirring constantly!) until the mixture thickens, darkens in colour and hits 107ºC/224ºF on your thermometer. It will take roughly 10-15 mins.

Turn off the heat and continue to stir for a few minutes to help cool the mixture, then pour over the brownie base and smooth out.

Allow to cool completely at room temperature, then slice into 16 bars, before moving on to the next step.

Topping instructions

Break the white chocolate (200g | 7oz) into a microwavable bowl and add the red food colouring gel (1 tsp). Heat in 10 second intervals in the microwave and make sure you stir well after each time.

When it’s two thirds melted, stir continuously (don’t reheat) until it’s completely melted.

Spoon the chocolate onto a few of the bars, allowing it to drip down the sides here and there. Then top each one with two edible eyes. Repeat until all your bars are decorated.

How to store Halloween millionaire brownies

Allow the chocolate to completely set then transfer them to an airtight container (I prefer metal) and store at room temperature. Consume within 5 days.

What makes brownies more fudgy than cakey?

Usually fudgy brownies contain a higher fat to flour ratio. In this brownie recipe – I melt chocolate and butter into the batter. This gives it quite a high fat content and a lovely fudgy texture. Cakey brownies tend to have more flour.

What is the best way to melt chocolate?

There are many different ways to melt chocolate. I’ve found the easiest to be in the microwave – heating in 10 second intervals and stirring well after each time.

Once the chocolate is two thirds melted, stir until it’s completely melted. This method ensures the chocolate doesn’t get too hot, which can have all kinds of annoying consequences!

What do I do if I burned my caramel?

If the whole thing is completely burnt, there’s not much you can do I’m afraid. It’s back to the drawing board!

Have burnt bits running through your caramel? If you act quickly, you can run the caramel through a sieve. This should get most of it out and leave a nice caramel to for you to work with.

To prevent your caramel from burning, make sure you stir constantly and right into the edges of the pan throughout the whole cooking time. If it’s getting a bit much, turn the heat down a little too.
