Preheat oven to 170 C.

Line two baking trays with parchment paper.

Put butter into a medium-large bowl and soften. Add sugar and beat with an electric mixer until pale and creamy (approx 2 mins).

Add egg and vanilla and beat through on low setting.

Sift in spelt flour and baking powder and fold through until just combined (I actually get my hands in and mix it together)

Add peanuts and choc chips and fold thorugh

Put tablespoons of the batter around 4 cm apart onto the tray and gently flatten

Bake 10 minutes, spin trays around, bake another 5 minutes until just golden.

Cool on trays for a few minutes allowing them to set slightly.

Cool completely on wire rack.

Store in airtight container.
