No-bake Rainbow Slice - VJ Cooks (2024)

If you love my collection of no-bake slices then get ready to addRainbow Sliceto your favourites. With a crunchy, dark chocolate base and white chocolate topping, this slice is hard to resist! Decorated with smarties and sprinkles it looks great on the table at birthday parties.

This slice is so easy to make. If you have young kids around, they love to get involved by sorting the smarties into colours, counting them (and let's be honest, eating them!). I like to make rainbow rows of smarties but if you're relaxed about it, you could let the kids arrange them.

HOW TO MAKE rainbow slice:

Start by lining a slice tin (approx 19 x 29 cm) with baking paper. Next melt the butter, condensed milk and dark chocolate together in the microwave then mix well. Place the crushed biscuits in a large bowl together with the rice bubbles. Pour in the melted chocolate mixture and stir until combined. Press the base mixture into the lined slice tin, spreading it all the way to the edges. Use the back of a metal spoon to smooth it out.

For the topping, melt the white chocolate in the microwave, add the oil and stir until smooth. Pour the white chocolate mix over the base, spreading it out evenly to the corners. Arrange the smarties in lines of each colour, then shake over the sprinkles.

Chill in the fridge for at least 4 hours (or overnight) until set. Take the slice out of the fridge a good 20 minutes before cutting into slices.
