How to Make Millionaire’s Shortbread
We’ll tackle this one layer at a time. It’s easy when you break it down.
Part 1: The Shortbread Base
The base is the foundation. It needs to be sturdy, buttery, and delicious.
Step 1: Heat your oven to 350°F (175°C). Line your 8×8 inch pan with parchment paper, leaving some hanging over the sides. This will help you lift the bars out later.
Step 2: In a bowl, mix the flour, sugar, and salt. Add the cold, cubed butter.
Step 3: Use your fingertips or a pastry cutter to rub the butter into the flour mixture. Keep going until it looks like coarse breadcrumbs.
Step 4: Dump the mixture into your prepared pan. Press it down firmly and evenly with your fingers or the back of a spoon.
Step 5: Bake for about 20 minutes, or until it’s lightly golden. Let it cool completely in the pan. Don’t rush this part.
Part 2: The Gooey Caramel Layer
This is where the magic happens. A perfect caramel is soft, chewy, and rich.
Step 1: In a medium saucepan, combine the sweetened condensed milk, butter, brown sugar, and golden syrup.
Step 2: Heat it over medium-low heat. Stir constantly with a whisk until the butter is melted and the sugar is dissolved.
Step 3: Once it starts to bubble, keep stirring for about 5-7 minutes. The caramel should thicken and turn a beautiful golden-brown color.
Step 4: Remove it from the heat and stir in the vanilla extract and salt.
Step 5: Pour the hot caramel over your cooled shortbread base. Spread it out evenly. Let it cool and set for at least an hour. You can put it in the fridge to speed it up.
Part 3: The Chocolate Top
The final layer is a simple, crisp chocolate topping.
Step 1: Melt your chocolate. You can do this in the microwave in 30-second bursts, stirring in between. Or, use a double boiler on the stove.
Step 2: If you’re using it, stir in the coconut oil or butter. This makes the chocolate a little shinier and easier to cut.
Step 3: Pour the melted chocolate over the set caramel layer.
Step 4: Gently tilt the pan or use a spatula to spread the chocolate into an even layer.
Step 5: Let the chocolate set. You can leave it at room temperature for a few hours or pop it in the fridge for about 30 minutes.
Pro Tips
I’ve made these bars hundreds of times. Here are a few things I’ve learned that make a huge difference.
- Don’t Overwork the Shortbread: When you’re mixing the butter and flour, stop as soon as it looks like breadcrumbs. Overmixing makes the base tough instead of tender.
- Patience with the Caramel: The key to smooth, not grainy, caramel is low heat and constant stirring. Don’t walk away from the stove. It can burn in an instant.
- Cutting the Bars Cleanly: The chocolate top can crack when you cut it. To avoid this, use a large, sharp knife. Run it under hot water, wipe it dry, then make your cut. Repeat for every single cut.
- The Parchment Paper Sling: Seriously, don’t skip the step of leaving parchment paper hanging over the sides. It makes lifting the entire block out of the pan so easy.
Substitutions and Variations
Want to change things up? Here are some ideas.
| Swap For | Substitution | Notes |
|---|---|---|
| Gluten | 1:1 GF Flour | Check if it has xanthan |
| Dairy | Vegan Butter | Use a good quality one |
| Sweet Milk | Coconut Milk | Gives a slight coconut taste |
You can also get creative with the toppings.
- Sprinkle flaky sea salt on the chocolate before it sets.
- Use dark chocolate for a richer taste or white chocolate for a sweeter one.
- Add a swirl of peanut butter into the chocolate.
- Sprinkle chopped nuts or toffee bits on top.
Leftovers and Storage
These bars are great for making ahead of time.
They store best in an airtight container. They’ll last at room temperature for about 3 days.
If you want them to last longer, keep them in the fridge. They’ll be good for up to a week. The caramel will be a bit chewier when it’s cold.
FAQs
Q1. Why is my caramel layer grainy?
Ans: This usually happens when the sugar doesn’t dissolve completely or the heat is too high. Cook the caramel low and slow, and stir constantly until you can’t feel any sugar granules.
Q2. My caramel is too hard/too runny.
Ans: This is all about cooking time. If it’s too hard, it was cooked a little too long. If it’s too runny, it needed a few more minutes on the stove to thicken up.
Q3. Why did my chocolate layer separate from the caramel?
Ans: This can happen if the caramel is a bit greasy or if you put the chocolate on when the caramel is still too warm. Make sure the caramel is fully set and cool before adding the chocolate.
Q4. Can I freeze Millionaire’s Shortbread?
Ans: Yes! They freeze really well. Cut them into bars first, then place them in a single layer on a baking sheet to freeze. Once solid, you can transfer them to a freezer bag. They’ll last for up to 3 months.
