Step 1

Preheat oven to 180°C. Brush a 17 x 27cm (base measurement) slice pan with melted butter to lightly grease. Line the base and 2 long sides with non-stick baking paper, allowing the sides to overhang.

Step 2

Sift the combined flours into a bowl, returning the husks to the bowl. Add the oats, coconut, sugar, sunflower seeds and sesame seeds, and stir to combine. Make a well in the centre.

Step 3

Place the peanut butter, honey and butter in a saucepan over low heat. Cook, stirring, for 2 minutes or until melted and well combined. Remove from heat. Add peanut-butter mixture and egg to the flour mixture and stir until well combined.

Step 4

Press the mixture into the prepared pan. Bake in preheated oven for 20-25 minutes or until slice is golden brown and set. Set aside to cool completely. Cut into squares to serve.
