Chocolate Rum & Raisin Oaty Cookies

These are a lovely new version of my popular Adaptable Oaty Biscuits*. The chocolate flavour is lusciously dense then the rum comes through just enough to make its presence felt in a tasty way.

Makes: About 20

Level: Very easy

Time: 30 minutes hands on & prep. then 15 minutes baking + cooling. (+ Another 20 minutes if you can’t get them all in the oven in one go.)

Equipment: Nothing special, just a bowl a saucepan, wooden spoon and baking trays.


  • 100g/3½oz raisins
  • 50ml/1¾fl oz  rum
  • 150g/5½oz porridge oats
  • 150g/5½oz plain flour
  • 20g/¾oz  cocoa powder
  • 100g/3½oz choc chips or pieces (dark or milk)
  • pinch of salt
  • 100g/3½oz unsalted butter
  • 150g/5½oz light soft brown sugar
  • 30g/1oz treacle
  • 30g/1oz golden syrup
  • 1½ Tbsp boiling water
  • ½ tsp bicarbonate of soda


Pre: Soak the raisins in the rum the night before baking.

1. Heat oven to 170°C / fan 150°C / 325°F / Gas 3.  Line two or three large baking trays with non-stick baking parchment.

2. Heat the butter, sugar, treacle and golden syrup in a medium saucepan.

3. In a large bowl, mix the oats, flour, cocoa powder and choc chips with a pinch of salt. Strain the raisins. (If you do it over the pan of butter and sugar the rum won’t be wasted.)

4. Once the butter and sugar mixture has melted, remove from the heat. Mix the boiling water and bicarbonate of soda in a small bowl then pour this into the butter and sugar mix. It will froth up so quickly stir to combine. Mix this into the dry ingredients and stir until everything is fully coated and all combined.

5. Make balls of the mixture and put on the lined trays, leaving lots of space between them. Flatten each ball slightly. (walnut size = medium biscuits)

6. Bake for 13-15 minutes. (*Even though I have a fan oven I still change the trays around halfway through baking to ensure an even bake, but I have to move quickly to avoid losing too much oven heat.)

7. Leave the baked biscuits on the trays for about five minutes then transfer to wire racks to cool completely.
