Step 1

Preheat oven to 170°C. Grease a 19cm x 30cm slice pan and line the base and sides with baking paper. (If you do not have a tray this size, use a similar, smaller pan rather than a large one. This is a thin slice and the mixture may not be enough to fill a large pan.)

Step 2

Combine the butter, sugar, flour and almond meal in a large bowl and mix well to combine (if the mix seems floury, add a little extra butter). Spread evenly over the base of the prepared pan. Bake for 12-15 minutes until lightly golden. Remove from the oven and stand on a wire rack.

Step 3

Meanwhile, to make the topping, place the butter and honey in a small heavy-based saucepan over medium heat. Simmer, stirring occasionally, for 3-4 minutes until mixture is lightly caramelised. Stir in the nuts. Pour evenly over the cooked base. Bake for a further 12-15 minutes until golden. Remove and stand on a wire rack and cool completely. Cut into slices to serve.
