Easy no-bake Maltesers Rice Krispie slices with a crunchy chocolate base, chopped Maltesers and a delicious caramel layer. Perfect traybake treat.

Malteser Millionaires Rice Krispies

These easy no-bake Maltesers Rice Krispie slices are honestly my favourite no-bake recipe right now and if you love Maltesers, you’re going to be obsessed. There’s just something about bag Maltesers that tastes better than the boxed ones… and this recipe uses plenty of them.

The base starts with a simple chocolate Rice Krispie layer, made by mixing crispy rice cereal with melted chocolate to create the most delicious crunchy no-bake base. I used classic Rice Krispies, but you could easily swap them for Coco Pops if you want an even more chocolatey slice (and I fully support that decision).

Chopped Maltesers are mixed straight into the base, but because there’s no such thing as too many Maltesers, even more are added on top. The crunchy base is finished with a smooth microwave caramel layer, making this recipe incredibly beginner-friendly, no candy thermometers or hob cooking required.

To take things to the next level, the caramel is topped with Maltesers spread for extra flavour and creaminess. If you can’t get hold of the spread, don’t worry, melted milk chocolate works perfectly and can be finished with even more Maltesers on top.

This no-bake Maltesers traybake is quick, easy and completely oven-free, making it ideal for busy days or last-minute desserts. Loved by both kids and adults, these slices are perfect for school lunchboxes, work snacks, parties, bake sales, or an indulgent dessert when you’re craving a caramel chocolate treat.

Microwave Caramel

Microwave caramel is honestly my go-to caramel method and one I recommend all the time, especially for no-bake recipes. It’s far simpler than the hob method and much less stressful, no boiling sugar, no thermometers, and no burnt fingers. If you’ve ever struggled with stovetop caramel, this method is a game changer.

To make easy microwave caramel, simply add condensed milk, butter, golden syrup and caster sugar to a large microwave-safe bowl. Microwave in short bursts of 30 seconds to 1 minute, depending on how powerful your microwave is. If your microwave runs hot, always stick to 30-second bursts. Stir thoroughly after every burst to ensure the ingredients combine evenly and don’t catch on the bottom.

The caramel usually takes around 8–10 minutes in total and will gradually turn a rich golden colour as it thickens. Patience is key here, rushing the process can cause the caramel to split.

If your microwave caramel splits, don’t panic. This usually happens when the mixture gets too hot, causing the fat to separate from the sugar. If it’s only slightly split, you can often rescue it by using a hand blender to bring it back to a smooth, glossy consistency.

For more stubborn cases where the caramel separates into oily and sugary layers, transfer it to a saucepan over low heat. Add 1–2 tablespoons of milk, cream, or water to help re-emulsify the mixture. Whisk constantly and gently until the caramel comes back together and becomes smooth again. Once fixed, remove from the heat immediately to avoid it splitting again.

Ingredients

• Rice Krispies– These form the base of the no-bake traybake, adding a light, crunchy texture that pairs perfectly with chocolate and caramel.
• Milk chocolate– Melted and mixed with the Rice Krispies to create a rich chocolate base that helps the slice set firmly without baking.
• Maltesers– Adds delicious honeycomb chocolate.
• Sweetened condensed milk– Essential for making the microwaveable caramel. Do not substitute with evaporated milk, as it won’t set correctly.
• Unsalted butter– Adds richness and helps create a smooth, creamy caramel texture.
• Golden syrup– Used in the caramel layer to add sweetness and that classic millionaire flavour.
• Caster sugar– Helps thicken and sweeten the caramel for a perfectly indulgent layer.
• Maltesers spread– Spread over the top to add even more Maltesers flavour and an extra indulgent finish (and yes, it’s as good as it sounds).

Tips & Tricks

• Line your tin well– Use baking paper with overhang so the slice is easy to lift out once set.
• Melt chocolate gently– Overheating milk chocolate can cause it to seize. Melt slowly and stir often.
• Press the base firmly– Compacting the Rice Krispie mixture well will prevent the base from crumbling when slicing.
• Microwave the caramel in short bursts– Stir between each burst to keep the caramel smooth and prevent burning.
• Let each layer set slightly– Allow the base to cool before adding the caramel for neat, defined layers.
• Use a warm knife to slice– This helps cut clean squares through the chocolate and caramel layers.
