Ingredients
Method
1.Butter a shallow 30cm x 21cm tin or line it with baking paper.
2.Sift the cocoa and brown sugar into a large saucepan and add the butter, honey and walnuts. Set over a gentle heat and stir constantly until the butter and honey melt and everything is well combined.
3.Increase the heat to medium and bring to a simmer, stirring all the time. Simmer for 3 minutes, still stirring constantly. The mixture will bubble up and thicken as the sugar cooks.
4.After 3 minutes, remove the pan from the heat and add the vanilla followed by the rice bubbles. Mix everything together quickly and press evenly into the prepared tin. Leave for a few minutes to cool a little and then cut into neat fingers. (The mixture sets firmly almost immediately.)
5.Leave until completely cold before removing from the tin and breaking into fingers along the cutting lines. Store airtight.
