Line a 7x10 rectangular baking dish with wax paper.

In a small saucepan over medium-low heat, melt the chocolate. Spoon 1/3 of the melted chocolate into the pan.

Stir the peanuts into the remaining melted chocolate.

Gently press the Twix bars into the pan. Spoon the remaining chocolate and peanut mix over the bars, smoothing as best as possible.

Place in fridge to chill completely.

When ready to serve, chop into strips (like biscotti!) and dish up.
