Method

1. Lightly grease 2 large baking tins.
2. In a SPAR Good Living 3 litre porcelain mixing bowl, place the margarine, peanut butter, sugar, eggs and vanilla essence. Mix thoroughly on high speed if using a hand-held electric mixer, to a creamy mixture.
3. Blend in the remaining ingredients in the order they appear.
4. Roughly divide the mixture in half, and shape each into a log resembling the diameter of a swiss-roll. Freeze for at least 30 minutes.
5. Meanwhile pre-heat the oven to 180 ºC.
6. Slice both rolls into 8, and place each slice spaced well apart onto prepared baking tins, pushing down on each with your palm to flatten further and increase their size.
7. Bake for 15 - 20 minutes.
8. Using a broad lifter, transfer the biscuits to cooling rack a few minutes after removing from the oven.
9. Store in an airtight container.
