No-Bake Chocolate Hazelnut Traybake

On a hot day, when I don’t want to turn on the oven, I often look for a no-bake traybake. And this No-Bake Chocolate Hazelnut Traybake fits the bill beautifully. You don’t even need to use the stove, as this can all be prepared in the microwave. Chocolate, biscuits, marshmallows and hazelnuts. Mixed together and topped with a layer of chocolate and Nutella.

If you don’t have a microwave, then you can easily do this in a double boiler instead. Just set a large bowl over a saucepan of simmering water and heat until the butter and chocolate are melted. (Making sure that the bottom os your bowl doesn’t touch the water.) Then add most of the marshmallows and heat a little more until the marshmallows are puffy and starting to melt, then mix in the rest of the ingredients.

Because of the hazelnuts in the base of this No-Bake Chocolate Hazelnut Traybake, I added a couple of tablespoons of Nutella (chocolate hazelnut spread) to the melted chocolate on top. Simply melt the chocolate first and then stir in the Nutella until well incorporated, before spreading over the top of the traybake.

The white chocolate is mostly decorative, so you can leave it out if you prefer. Feel free to be as abstract or as precise as you like with the drizzling!

And that’s about it really. Super simple. Although, if it’s too hot to turn the oven on, like it has been here recently, then it’s best to keep this traybake in the fridge so the chocolate doesn’t melt too much!
