Low Carb Millionaire Caramel Shortbread

  • 1g of carbs
  • 90 mins
  • Serves 24


  • For the shortbread:
  • 125g / 1 1/4 cups almond flour or ground almonds
  • 45g / 1/3 cup sweetener, I used erythritol
  • 1/4 tsp salt
  • 25g / 1/4 cup unsalted butter

  • For the caramel:
  • 35g / 1/3 cup salted butter
  • 3 tbsp sweetener, I used Sukrin Gold
  • 160ml / 2/3 cup double cream/whipping cream
  • 1 tsp vanilla extract

  • For the chocolate coating:
  • 85g dark chocolate, I used 85%
  • 2 tbsp unsalted butter


  1. To make the shortbread:
    Preheat the oven to 180℃/350℉/Gas Mark 4. Grease and line a square baking tin, I used an 8inch x 6inch sized tin.
  2. Place the dry ingredients for the shortbread into a blender (ground almonds, salt, and sweetener). Briefly blitz these ingredients to get rid of any lumps.
  3. Add the unsalted butter to the blender and blitz until a crumbly texture forms.
  4. Spoon the crumbly mixture into the lined baking tin. With the back of a spoon, smooth the mixture evenly across the bottom of the tin. Bake in the oven for 15 minutes. Remove from oven and set aside to cool.

  5. To make the caramel:
    In a medium sized pan, heat the salted butter and sweetener on a low heat. Stir continuously until melted.
  6. Once the butter has melted and the sweetener has dissolved, add the cream and switch to a medium heat, stirring regularly as you do not want this to burn. As soon as the mixture starts to boil, reduce the heat so that it goes to a light simmer. Let the mixture simmer for 10 minutes or until the mixture has thickened and coats the back of a spoon, stirring regularly.
  7. Remove pan from heat and whisk in the vanilla extract.
  8. Pour the caramel over the shortbread and smooth over until it is evenly covered with caramel. Leave in the fridge to set for 15-30 minutes.

  9. To make the chocolate topping:
    Melt the dark chocolate and unsalted butter in the microwave. This can be done by heating for 30 seconds and then stir and repeat until the chocolate and butter are melted. Alternatively, you can add the chocolate and butter into a heatproof bowl set over (not in) a saucepan of simmering water; cook, stirring occasionally, until melted, for 2 to 3 minutes.
  10. Pour the melted chocolate over the caramel and smooth over until the top is fully coated with chocolate.
  11. Leave the chocolate to set at room temperature. This will take between 1-2 hours.
  12. Once the chocolate has set, cut the shortbread into squares. I managed to cut 24 squares.
  13. Store the shortbread in the fridge and consume within 3-4 days. They taste best at room temperature so I recommend leaving them out for an hour before eating them. Or, you can be impatient like I am and eat them straight from the fridge!

I am obsessed with these Millionaire Shortbreads! It was my first time making a low carb caramel and I was pleasantly surprised how good it tasted. These are nice and easy to make. Be warned, these are moreish! Luckily they are nice and low in carbs. I had a serving of two and had no spike in my blood sugar levels.

In this recipe I used Sukrin Gold, an alternative to brown sugar. However, you can use a normal sweetener such as Erythritol or Xylitol.

I managed to cut 24 pieces of shortbread from this recipe, which makes them 1g of carbs per serving! As they are so low in carbs you could half it and cut it into 12 pieces to have a bigger shortbread.
