Chef’s Notes
The key to “smells that sell houses” is butter and sugar caramelisation — don’t underbake.
Oats add texture and give that comforting bakery aroma.
Let biscuits cool fully before storing to maintain crispness.
If they soften over time, refresh in the oven at 160°C for 5 minutes and cool again on a rack.
Stored correctly in an airtight tin, they’ll stay fresh for up to one week.
STORAGE
Cool completely before storing.
Use a metal tin or sealed glass jar.
Layer with baking parchment if stacking.
For crisp insurance, place a small muslin bag with uncooked rice in the container (do not let it touch biscuits directly).

Method
Preheat oven to 180°C (fan 160°C). Line two baking trays with parchment paper.
In a saucepan over low heat, melt the butter, sugar and golden syrup until smooth and combined.
Remove from heat and allow to cool slightly — this prevents the chocolate chips from melting prematurely.
Stir in flour, bicarbonate of soda, oats, cocoa powder and chocolate chips until fully combined.
Roll dough into walnut-sized balls and place on trays, leaving space between each.
Flatten slightly with the back of a spoon.
Bake for 14–16 minutes until golden at the edges.
14 minutes = softer centre
16 minutes = crispier finish
If adding filling, gently press an indentation into the centre while biscuits are still warm.
Cool for 5 minutes on trays before transferring to a wire rack.
Filling & Topping
Once fully cooled, spoon a small amount of caramel into each indentation.
Melt chocolate gently over warm water.
Spoon over caramel and spread evenly.
Allow to set completely before storing.
