🛒 Key Ingredients
A full ingredients list along with Metric and US Customary measurements, can be found in the recipe card at the end of this post.
Mars Bars - The base of the slice, melted down to create that signature chewy, caramel flavour. Substitute with Milky Way bars for a similar result.
Rice Krispies - Adds a light, crispy crunch that balances the richness. Any puffed rice cereal works well.
Mini Eggs - Brings a festive Easter touch with a crunchy shell and chocolate centre. Swap for crushed chocolate eggs, M&M's, or Maltesers if needed.
Chocolate (Milk & Dark) - Melted on top for a rich, smooth finish. You can use all milk chocolate for a sweeter taste or all dark for a deeper flavour.
Butter (Unsalted) - Helps melt the Mars bars smoothly and binds everything together. Margarine can be used, but butter gives the best flavour.

🔪 How to make mini egg mars bar slice
One: Place the chopped mars bars and butter in a pan and melt on a low heat.
Two: Take the pan off the heat and stir in the Rice Krispies and mini eggs.
Three: Press the mixture into a 20cm lined tin. Press down with the back of a heavy metal spoon.
Four: Melt the dark chocolate and milk chocolate in microwave in 30 second bursts, stirring in between. Pour the melted chocolate on top of the Mars Bar slice then sprinkle over chopped mini eggs. Allow to set for at least 3 hours before cutting into squares.
Top Tips
- Line your tin - Prevents the Mars Bar slice from sticking and makes it easy to lift out and cut.
- Melt gently on low heat - Mars bars can burn or split, so keep the heat low and stir constantly.
- Press the mixture firmly into the tin - Helps it hold together and gives neat, even slices.
- Add a little vegetable oil to the topping - Keeps the chocolate smooth and prevents cracking when cut.
- Allow it to set properly - Chill for at least 3 hours, but ideally overnight for the best texture and clean slices.
Storage
Store - Keep in an airtight container in the fridge for up to 5 days. It's best served chilled for the perfect chewy texture.
Freeze - Freeze in a sealed container (or wrapped individually) for up to 3 months. Defrost in the fridge overnight before serving.
