Step 1. Gather the ingredients
Step 2. Combine all ingredients (except Tim Tams)
Step 3. Spread a layer of brownie goo in a pan
Step 4. Mmmmm Tim Tams
Step 5. Cover with more brownie goo
Step 6. Cook for 30 minutes at 190C
Step 7. Lick the bowl
Step 8. It’s done when a skewer comes out clean, then cool in the pan for 15 minutes
Step 9. Remember that you should have used baking paper to line the tin
Step 10. Try drowning it in faux cream to see if that helps
VERDICT: Tim Tam brownies are not as nice as they sound. Apart from all the cooking problems that may have been related to my lack of skills – the chocolate melts, but the biscuits stay hard. In fact the biscuits get harder. Maybe if you crushed the biscuits up, or soaked them in something for an hour or two first… but I think you’d be better off making brownies AND having Tim Tams.
