Mars Bar Slice
Description
The Mars Bar Slice blends chopped Mars bars with butter and golden syrup, heated gently until smooth and runny. This caramel-like mixture is quickly combined with rice bubbles, which add a crunchy texture throughout the slice. The mixture is pressed firmly into a lined and greased slice tin. Once settled, a layer of melted milk chocolate is poured over the top and spread evenly. The slice is then chilled until firm, allowing the chocolate to set into a glossy finish.
The final slice offers chewy, chocolate-caramel richness paired with the crispness of rice bubbles. The golden syrup contributes to a smooth caramel flavor, complementing the distinct Mars bar sweetness. This slice is suitable for casual gatherings or a sweet treat at home and can be stored cool to maintain its chewy yet crunchy texture.
For best results, store the slice in the refrigerator, especially during warm weather, to keep it firm. It can last several weeks when kept in an airtight container. The slice also freezes well for one to two months; thaw before eating. Variations on the golden syrup include maple syrup, honey, or corn syrup to adjust sweetness or availability.
Ingredients
- 4 ½ Mars bars (47 gram bars)
- 3 cups rice bubbles (100 grams)
- 60 grams butter
- 2 teaspoons golden syrup
- 240 grams milk chocolate (you can get away with 180 grams, which is one family block of Cadbury's, but the extra 60 grams is ideal)
Instructions
- Grease a slice tin (around 27 x 17cm) with butter and then line with baking paper, leaving extra on sides (to pull the slice from the tin once cooked) (see picture above).
- Measure rice bubbles into a large mixing bowl.
- Break mars bars into pieces with your hands and put into a saucepan. Add butter and golden syrup.
- Place saucepan on low heat while stirring to combine.
- Keep stirring until the mixture reaches a smooth, runny consistency. Use a whisk to stir the mixture towards the end of the process to help get that completely smooth consistency. The mixture should resemble melted chocolate, with no lumps.
- Add mixture to rice bubbles and stir quickly to combine.
- Spread out mixture in the slice tin, spreading evenly to the edges and then pressing into the tin firmly with the back of a metal spoon.
- Melt chocolate in the microwave using 20 second bursts (check and stir after each burst).
- Pour melted chocolate over the slice and angle tin from edge to edge to help chocolate reach each side and corner of the slice tin.
- Place in fridge for 15-30 minutes. Ideally, the chocolate shouldn't be completely set when cutting (it will crack as you're cutting if it's too hard). Alternatively, if you've left the slice in the fridge for longer just let the slice rest at room temperature for at least 20 minutes before cutting into squares.
- Remove slice from tin by lifting edges of baking paper, cut into squares and return to the fridge.
Notes
- Store the Mars Bar Slice in the refrigerator to maintain firmness, especially in warm weather.
- Slice will keep several weeks if stored in an airtight container.
- Freeze for up to two months; thaw fully before serving.
- You can substitute golden syrup with maple syrup, honey, or corn syrup.
- Use fresh, good-quality ingredients for the smoothest texture.
